Mini Excavator Parts: OEM Rubber Products from Elasto Proxy

Описание: Mini Excavator Parts: OEM Rubber Products from Elasto Proxy Mini excavator parts from Elasto Proxy are industrial rubber products for sealing and insulation. They are designed for compact or mini excavators, tracked or wheeled vehicles that can weigh up to 20,000 lbs. and are used in construction, landscaping, hole digging, pipe trenching, and snow removal. Unlike standard excavators, compact excavators can fit into smaller spaces and are easier to transport. The mini excavator parts that original equipment manufacturers (OEMs) can buy from Elasto Proxy include: Door gaskets Window seals Headliners Floor mats Firewall insulation Silicone hoses and connectors Other molded rubber and plastic parts OEMs who partner with Elasto Proxy can buy mini excavator parts in low-to-medium volumes and benefit from of our value-added services. For example, Elasto Proxy can ship door seals on demand or according your sales forecast. With our kitting and assembling packaging, we can also deliver all of the rubber parts that you need for a build in the parts’ order of assembly. Mini Excavator Cabin Parts Door and window gaskets for mini excavators need to provide environmental sealing and sound reduction. Rubber seals that admit wind, water, dirt, and outside temperatures are ineffective, but so are gaskets that don’t reduce noise. If you’ve been cutting and bonding lengths of rubber in-house, ask Elasto Proxy how outsourced rubber fabrication can also help you to reduce labor costs and material waste. For example, if a worker cuts a profile incorrectly, the mis-cut probably winds up in the trash. Asking a higher-paid employee such as a welder to cut and bond rubber adds excessive labor costs. Attaching gaskets with hand tools or messy liquid adhesives extends assembly times. Outsourced fabrication that’s combined with gasket taping, kitting, parts marking, and custom packaging can add value instead. In addition to door seals and window gaskets, Elasto Proxy makes acoustic insulation such as headliners for mini excavators. Elasto Proxy can supply you with headliners in the colors and sizes that you need, and with pre-cut openings for fasteners. With our water jet cutting services, you won’t have to pay for or wait for tooling either. If you need molded parts, we can source these for you, too. Mini Excavator Engine Parts Mini excavator parts from Elasto Proxy include thermal-acoustic insulation that keeps heat and noise in the engine bay from reaching the cabin where the operator sits. Thermal insulation protects the cab from high temperatures that can cause driver discomfort and damage electronics. Acoustic insulation dampens sound-induced vibrations that can loosen fasteners and harm human hearing. Thermal-acoustic insulation can provide mini excavator manufacturers with a complete solution. It consists of specialized materials that are assembled into a sandwich-like structure. The top layer is an aluminum facing or metallized Mylar that’s laminated to an elastomeric foam. This facing reflects radiant heat and withstands water and engine oil. The middle of this insulation sandwich consists of a layer of hard rubber that stops loud engine sounds and a layer of acoustic foam for additional sound absorption. The bottom layer uses a pressure-sensitive adhesive with a removable liner. Taped insulation installs easily and eliminates the health and safety concerns of adhesive spraying. OEM Rubber Products from Elasto Proxy Like the gaskets in the cabin, engine insulation needs quality fabrication. Otherwise, potential buyers may assume that poor-quality mini excavator parts reflect larger flaws in a product design. Sealing and insulation that fails in the field can result in warranty work and equipment downtime. Success is readily achievable, however, so partner with us for the rubber parts that you need. Demolition excavator parts need to provide reliable sealing and insulation because there are costs and consequences to defects. Leaky door and window gaskets can admit rain or snow that wets floors and seats. Using inadequate thermal or acoustic insulation can also diminish operator comfort and put safety at risk. From the cabin to the engine bay, demolition excavators need quality rubber components. Rubber gaskets are demolition excavator parts that provide both environmental sealing and acoustic insulation. Seals that admit wind, water, dirt, and outdoor temperatures are ineffective, but so are gaskets that fail to absorb road noise. In addition to quality, manufacturers need to consider labor and material costs. Ease-of-installation and the added value a gasket fabricator can provide are also worth considering. Seal design follows a formula with three basic elements: compound, hardness, and profile. Use a compound, or type of rubber, that can withstand tough outdoor environments. Harder rubber provides greater impact resistance but can make it more difficult for a door or window to close. Softer rubber provides greater cushioning but is more prone to compression set, or permanent deformation. Profile refers to the shape of the gasket material, which is extruded into coils or lengths. Cutting and bonding your own gaskets may seem inexpensive enough until you consider the true costs. If a worker cuts a profile incorrectly, the mis-cut become material waste. Asking a higher-paid employee such as a welder to cut and bond rubber adds excessive labor costs. Attaching gaskets with hand tools or messy liquid adhesives extends assembly times. Outsourced fabrication that’s combined with gasket taping, kitting, parts marking, and custom packaging can add value instead. Engine Insulation Demolition excavator parts include engine insulation that keeps heat and noise from the engine bay from reaching the cabin where the operator sits. Thermal insulation protects the cab from high temperatures that can cause driver discomfort and damage electronics. Acoustic insulation dampens sound-induced vibrations that can loosen fasteners and harm human hearing. Thermal-acoustic insulation can provide equipment manufacturers with a complete solution. It consists of specialized materials that are assembled into a sandwich-like structure. The top layer is an aluminum facing or metallized Mylar that’s laminated to an elastomeric foam. This facing reflects radiant heat and withstands water and engine oil. The middle of this insulation sandwich consists of a layer of hard rubber that stops loud engine sounds and a layer of acoustic foam for additional sound absorption. The bottom layer uses a pressure-sensitive adhesive with a removable liner. Taped insulation installs easily and eliminates the health and safety concerns of adhesive spraying. WHAT IS VIBRATORY HAMMER? Vibratory hammer is a machine used to drive tube and sheet piles in/out of the ground for constructing structures like bridges, harbours, roads, airports, canal works and so on. So they are quiet and have many advantages compared to traditional pile drivers which use a large weight to strike the pile. As an example, the greatest advantage is that vibratory hammers can drive and extract piles much faster. Besides this, they are small and lightweight, environmentally friendly and they can be used underwater. Moreover, in some vibratory hammers vibration can be fully controlled, which is a necessity if the work has to be carried out in residential or historical places. Because vibro hammers use spinning counter-weights to create a vibration to the pile the resistance of the ground is reduced with vibration and by changing the formation of the ground. The vibratory piling machine transfers vertical vibrations to the pile via the hydraulic clamp. This, in turn, transfers vibration to the ground which reduces the friction between the pile and the ground. In other words, the high-speed vibration causes the soil to actually “liquefy” allowing the pile to be driven or extracted with less force. As a result, the pile is driven into the ground by a combination of the vibrator’s weight and centrifugal force it creates. VIBRO HAMMER COMPONENTS: Vibration Suppressor, Vibration Case, Hydraulic Clamp and Power Unit. VIBRATION SUPPRESSOR The vibration suppressor assembly is mounted to the top of the vibration case to isolate vibration to the crane and permit pile extraction. VIBRATION CASE The vibration case contains high amplitude eccentric weights cast in one piece with gear which rotates in a vertical plane to create vibration. The eccentric weights are driven by hydraulic motors mounted on the vibration case. So the motors and eccentrics are all gear connected to maintain proper synchronization. The eccentrics and motor shafts are mounted in a heavy-duty cylindrical bearing. The gear and bearing lubrication are provided by the radiator located in the Power Unit. There are oil pumps, installed to vibration case, circulating the oil between vibration case and radiator to reduce the oil heat in the vibration case. HYDRAULIC CLAMP Hydraulic clamp is the part of the vibrator which grips pile or tube. It contains two gripping jaws. One is “fixed” and one is “moveable”. Movable jaw is operated by the cylinder located in the clamp body. Besides this,there is a check valve on the clamp which keeps jaws closed in any kind of emergency. POWER UNIT (HYDRAULIC POWER PACK) Vibratory hammers are powered by the power unit. For excavator mounted hammers power unit is the excavator itself. For crane suspended hammers there is a power unit which is connected to the hammer by hydraulic hoses. There is a diesel engine inside the power unit which drives hydraulic pumps that create hydraulic pressure to operator vibro hammer. The diesel engine is mounted to a tubular frame that also serves as a diesel fuel tank. There are also emergency stop buttons on the machine. If you are interested in vibratory hammer you may also want to learn about production process of vibro hammer in our manufacturing facility. Using our 30 years experience in this field we can perform special design and production to meet customers’ needs and requests. FEATURES AND ADVANTAGES OF VIBRATORY PILE DRIVERS Vibratory pile drivers are used to build harbors, bridges, airports, buildings, roads, rails, infrastructure, solar power, wind turbines, walls and many other foundation types. Vibratory pile drivers are modern and popular machinery for pipe, sheet and wooden piles. The most prominent feature of vibratory pile drivers is the sound power level. Impact hammers are very noisy owing to the fact that they make use of overweight to impact. However, vibratory hammer drivers are lighter and much faster as they do not apply extra force to the ground. Therefore that are more preferable in urban areas and downtowns.

The Best Folding Saws for Hunting and Bushcraft

Описание:  The Best Folding Saws for Hunting and Bushcraft Breaking sticks over your knee is not a good strategy. For starters, it’s not precise. If you’re building a blind or lean-to, you need matching lengths. And if you’re hunting, you obviously can’t be cracking wood. What’s the solution? Folding saws may seem like just another piece of gear to stuff in an already overflowing pack, but like everything else, they’re essential for solving common problems in the woods. A great saw keeps you prepared without weighing you down. We’ve put together a guide on folding saws specifically for hunters and outdoorsmen and finished it off with our six favorites. Our Top Folding Saw Picks Eversaw All Purpose– “All-purpose saw for wood, bone and plastic” No products found.– “Light weight and compact size make it great for serious outdoorsman” arvol Folding Handsaw– “An excellent option for thick woods” Coher Folding– “Its versatility make it great for DIY projects” Corona RS 7255D Razor Tooth– “Stand hunters can benefit from its power in small spaces” Tabor Tools TTS25A– “The ergonomic design makes this saw a top choice” Why do I need a folding saw? Like most outdoor activities, hunting requires at least some wilderness survival skills and the tools that go along with them. The more tools you have to assist you, the easier your hunting trip will be. Chances are you’ll run into some tough obstacles, so a folding saw to cut through them is an essential accessory. Saws are great for bushcraft like building your own ground blind or prepping a tree for your stand. If you’re camping on your hunting trip, then of course you’ll have to cut would to clear an area and make a fire. Folding saws are compact and much easier to pack with your gear than an axe or full-sized saw. You can even use some folding saws to field dress animals. Wouldn’t an axe be better? Axes do have certain advantages. You can put a lot of power behind them. However, axes tend to be large and bulky to carry while saws are more compact. Saws have other upsides as well. Using a saw is actually quicker than an axe as well, on average about one-third of the effort is required. You also don’t need a ton of room for a saw like you do an axe. For branches which may be hard to reach, you can even ‘pole mount’ the blade for that sawing action. Bushcraft saws vs pruning saws There are some important factors you should consider when specifically choosing a bushcraft saw. Pruning saws can be a vital part of a home gardener’s arsenal, but they may not be as useful in the wilderness. When choosing a saw for camping, survival or bushcraft, you want something lightweight and portable, but still reliable. Build quality is more important since you’ll be packing it in with gear a lot. Unlike in your yard, you may not know exactly the types of trees and wood you’re going to encounter while hunting. It’s best to choose a tool that is as versatile as possible. Many of the woods you come across will be softwoods, like willow, which need large teeth for cutting. However, areas with harder wood will need a small-toothed blade. It’s probably best to choose a medium blade if you’re going to be hunting a lot of unfamiliar areas. Can you sharpen a folding saw? The blade of a folding saw may become dull over time, which results in a rough cut. A dull blade can also slow down your work or be more dangerous to use. Although many hardware or outdoor shops offer professional sharpening services, it’s easy to do at home. Tightly clamp the blade into a vise and use a small metal file or grindstone to sharpen the blade. You will notice the teeth of the saw alternate between flat and beveled edges. You only have to sharpen the beveled edges. Cutting Blades If you’ll be doing mostly up-close work, opt for shorter blades (about 6 inches) and short handles. For big jobs, such as cutting back an extensive privet hedge, choose longer blades (9 to 12 inches) and longer handles. Most quality hedge shears on the market are straight-blade shears made from forged steel. One advantage of straight blades is that they can be easily sharpened by hand with a millstone and/or sharpening stone. Ideally, the blades on your hedge shears should touch only at the cutting point to reduce friction and sticking. Some shears have serrations on one or both blades, which can be helpful when gripping and cutting twigs larger than ? inch. Another feature on some designs is a non-stick coating, purportedly to keep the blades from gumming up and/or rusting. Wavy-blade shears are also sold. They grip the twigs, preventing them from sliding along the blade while you’re cutting, an advantage with open-structured plants. The disadvantage is that wavy blades require professional sharpening. Another feature to look for is a good adjustable pivot-bolt assembly, which allows you to adjust the blade tension as necessary. This is often the first part of the tool to fail, so being able to buy replacement pivot bolts is an advantage. How to Choose the Best Loppers for You Loppers come in a range of styles, sizes, and price points; what’s best for you depends on the kind of pruning you’ll be doing, your size and strength, and your budget. Pruning can be heavy, repetitive work so it’s important to buy the right loppers. Loppers come with a wide range of handle/grip sizes, shapes, and materials. Some are “ergonomically designed” to fit your hand, while others are made of softer material to cushion impact. We found that the softer, foam grips are most comfortable, but they’re also the most prone to damage. Handles with contoured grips may be most comfortable for some people, but try it out before buying as not everyone holds loppers the same way. Also check on the size of the grips; some are rather short, which limits hand placement on the handles when pruning. All better loppers have a bumper or other cushioning mechanism (usually near the blades) to prevent the handles from smashing together as you complete a cut. Make sure that the bumper prevents your hands from touching as you cut and try closing the loppers forcefully to see how well the bumper absorbs shock. How a Pruning Saw Differs From Other Saws & Why It Matters Some saws might appear the same at first glance, but some key differences make the pruner saw ideal for the job of tricky pruning work. Anyone who knows me well (or has read my columns here) knows that I thoroughly enjoy pruning trees. It’s one of my favorite farming tasks—nothing can change a landscape more quickly than trimming the messy lower branches of a spruce tree, and I spend a good portion of the year going around the farm and working to keep encroaching trees and branches under control. There are also plenty of apple trees to care for, and of course they require occasional pruning as well, albeit with a focus on fruit production more than aesthetics. With this in mind, I was recently given a new pruning saw as a gift, and suffice to say I’m excited to start using it now that spring is just around the corner. You might wonder what makes a pruning saw different from any other saw. Pruning saws come in a few different shapes and sizes, with some of them attached to long poles and aimed at pruning out-of-reach branches high above your head. My new pruning saw is simpler—at first glance, it’s not much different than a regular hand saw—but a closer examination quickly reveals a few key differences that make it more ideal for tricky pruning work. First let’s consider shape. Rather than having a straight blade, my new pruning saw features a curved blade, and from what I understand this is often the preferred shape for pruning work. Having never used a curved blade before, I’m looking forward to comparing and contrasting the strengths and weaknesses of the two designs. What Is A Pruning Shear A pruner shear is a tool that is used for cutting and trimming plants. It has a long blade and a short blade. The short blade is for cutting and the long blade is for trimming. It is used to cut and trim plants such as roses and shrubs. There are various types of pruners on the market, but they all have similar blades. The difference between them is their size, shape and other features. Some are designed for indoor gardening or home use while others can be used outdoors. They are also made in different sizes, shapes and prices. The most common type of pruner shears is called an angled pruner. Many garden centers sell this kind of pruner because it is fairly easy to handle when you need to do some trimming around your house. It allows you to get close to the plant without having to bend over much. If you want a good quality pruning shear that is not expensive, then look for one with a rubberized grip to make sure it will hold up against rough surfaces. You should also check if it has a comfortable handle and easy-to-hold trigger lever. Most of all, try out the pruner by using it first before buying it. Are You Using Your Pruning Shears Correctly? Every gardener will need a pair of pruning shears at some point. Regular scissors may work, but they are not designed for severe cutting jobs. Before choosing on a pair of pruning shears for my garden, I broke a pair of kitchen scissors twice. I now use pruning shears for the majority of my pruning tasks in the garden. Pruning shears are a must-have gardening equipment for every gardener. However, utilizing it for the first time might be challenging. Fortunately, I have these suggestions, strategies, and a guide to assist you.Discover the many types of pruners. Pruners are classified into two sorts depending on their cutting mechanism. These are the anvil and bypass types. Similarly, in terms of blade design, the traditional parrot beak pruner is the third kind. The bypass type is compatible with the popular ratchet pruner, which can cut branches up to two centimeters thick.

Is Paper Lunch Box More Affordable than Plastic Container?

Описание: Is Paper Lunch Box More Affordable than Plastic Container? When you started your research to find the right packaging for your restaurant, you quickly realized that there was a multitude of different packaging options. Different materials, different shapes, different designs, etc. Depending on your needs, the choice can be complicated. To help you see more clearly, first, you can take a look at our article “How Select The Best Food Packaging for My Restaurant“. Before looking at the specific technical or visual characteristics of your packaging, you must first choose a material. As you may have already seen, the majority of food packaging is made of plastic, paper, aluminium or corn starch. Here, we will focus particularly on plastic containers and paper box lunch containers. Is paper packaging more expensive than plastic packaging? At first sight, we tend to think that paper packaging is more expensive than plastic packaging. Yes, the shortcut between more ecological and therefore more expensive is very often made by us, lambdas consumers. But know that this is not necessarily true. It all depends on the type of packaging we are talking about. In the rest of this article, we will compare 2 types of plastic packaging with a classic paper lunch box. This will allow us to analyse their prices as well as their strengths and weaknesses. The first plastic packaging in which we will be interested in the microwave plastic container and the second is the TAGE plastic container. Microwave Plastic Container The microwave plastic container is a rigid plastic packaging. In its form, it is similar to Tupperware. As its name suggests, it is possible to put it in the microwave. It is presented in 2 parts. The first is the main container and the second is the lid. This type of packaging is totally leakproof and food grade. Its price is generally around RM0.40 per piece TAGE Plastic Container The TAGE plastic container is made of thinner plastic than the previous one. It is presented in a single block with 2 symmetrical parts. That is to say, the part containing the food is the same as the lid. It also has all the characteristics of a food packaging. That is to say, it is completely leakproof and food grade. As for it, its price is RM0.15 per piece. Paper Lunch Boxes Finally, let us talk about paper box lunch containers. As its name suggests, this type of packaging is made of paper, but not just any type of paper. The latter is PE coated which makes it totally leakproof and grease proof. These lunch boxes are also totally food grade. Their price is about RM0.26 per piece. The Choice Is Yours Now that we have briefly seen these 3 types of packaging, what makes them different? Mainly their price will you tell me? Indeed, price is an element of decision that cannot be neglected during the purchasing process. But do you have to rely on that alone? The quality of the product is obviously an issue. You may want to choose the cheapest packaging but does the TAGE plastic container really reflect your brand? Is the quality of this packaging in line with the quality of your products? Each of the packaging presented obviously has its strengths and weaknesses. But to know which one you match, you have to ask yourself what are the values of your brand that you want to present through this packaging. What is a corrugated box? You are wondering that what is a corrugated box than we can come up with a single definition that when a flute paper which is made by compressing the Kraft containerboard in the shape of S arch and then sandwiched between the linear board with the help of the adhesive. This sheet is called a corrugated sheet and the box made out of it are called corrugated box. Why we use corrugated box? Well, there cannot be one particular answer to this as there are many advantages of using a corrugated box. This lightweight box can provide enough protection against the packed goods. We can look at the following points to understand the advantage of using a corrugated box. Corrugated box are much stronger than cardboard box Can be recycled and reused are made of biodegradable material Corrugated box offers flexibility and are also cost-effective Sustainable and cost-efficient Corrugated boxes are easily customizable and provides branding option. They are cost-effective, lightweight and provide sustainability. The Corrugated box is designed in such a way that it helps to protect the product from moisture and bacteria. Thus, is a great option for the packaging of food products ex: – Corrugated pizza box.Difference Between Corrugated vs Cardboard Boxes If you considered the cardboard box as same as corrugated box than you are having a lot of confusion in your head. Yes, they are not the same at all. Corrugated box are specially designed for shipping and packaging of larger products such as home appliances, or products which needs to be shipped with great care. Due to its durability, lightweight and product protection it is a better choice over cardboard box. Cardboard boxes are generally made up of a single layer of sheet with heavy paper-pulp. The Cardboard box is generally used as packaging material in the form of a cereal box, greeting boxes, food products, etc. The main difference between corrugated box and cardboard box is the process through which they are built. Though the raw material used in the manufacturing of both type of boxes is the same. The construction is pretty much different, the corrugated box usually consists of 3 or more than 3 layers of linear board with a flute sandwiched between them which increases the overall durability of the box. Whereas the cardboard box is made of a single sheet of heavy paper-pulp which is less durable as compared to corrugated boxes. Plastic Bags A major advantage of plastic bags is that, when compared to other types of shopping bags, producing them carries the lowest environmental toll. The thin, plastic grocery store bags are most commonly made from high-density polyethylene (HDPE). Although production of these bags does use resources like petroleum, it results in less carbon emissions, waste, and harmful byproducts than cotton or paper bag production. Plastic bags are also relatively sturdy and reusable. Many of the studies about different bagging options that show plastic bags production demands less resources assume plastic bags are used at least twice—once coming home and once as a trash bag—and factor this into the calculations about which bags are more sustainable. Plastic bags are recyclable, though few people recycle them. Recycling plastic bags is a difficult task; they fly away in the recycling plant and get stuck in machinery. Because of this, many cities do not offer curbside recycling for plastic bags. Instead, large-scale retailers offer bag recycling services. However these services are dependent on the consumer bringing the plastic bags back to the store. Bags that are not recycled end up becoming litter, because they do not biodegrade. In addition to filling up landfills and becoming eyesores, plastic bags that become litter endanger many facets of the environment, including marine life and the food chain. This is because plastic bags, like all plastic materials, eventually break up into microscopic pieces, which scientists refer to as microplastics. Microplastics have been found nearly everywhere: in marine animals, farmland soil, and urban air. Though scientists have only just begun studying the consequences of microplastic proliferation, and we do not yet know their effect on animals, humans, and the environment, scientists are concerned about how this level of plastic pollution could change our planet. The studies that found plastic bags to be less harmful to the environment than paper and reusable bags did not take effects of litter into account and instead assumed that the plastic bags would be recycled or used as trash bags. Paper bags have some advantages over plastic bags when it comes to sustainability. They are easier to recycle, and, because they are biodegradable, they can be used for purposes like composting. However, paper is very resource-heavy to produce: Manufacturing a paper bag takes about four times as much energy as it takes to produce a plastic bag, plus the chemicals and fertilizers used in producing paper bags create additional harm to the environment. Studies have shown that, for a paper bag to neutralize its environmental impact compared to plastic, it would have to be used anywhere from three to 43 times. Since paper bags are the least durable of all the bagging options, it is unlikely that a person would get enough use out of any one bag to even out the environmental impact. Still, the fact that paper is recyclable helps lessen its impact. In 2018, 68.1 percent of paper consumed in the United States was recovered for recycling, a percentage that has been rising in the last decade. However, because paper fibers become shorter and weaker each time the recycling process takes place, there is a limit to how many times paper can be recycled. Plastic cards, which today are already considered outdated, were not a thing not long ago. Even physical money - cash had to be born for a list of specific reasons. Before the invention of money, as a universal means of payment, people had a different approach to the process. Services and products were exchanged among the members of the commune. It successfully served the purpose for a long time, but when the world became more global, the need for more convenient methods arose. To trade goods between different groups, the universal payment method was needed. That is exactly how the first metal coins were invented. At first, they were made either from gold or silver to highlight their value. However, as money became more widely used, precious metal coins became simply metal coins. This was followed by the introduction of paper banknotes. The primitive ones were very basic pieces of paper with the value indicators on them. However, due to safety concerns and possibilities of crime, layered security systems were introduced and advanced for them. Whether we are talking coins or paper banknotes, cash, physical money remained unchanged for thousands of years. Despite their development, the system maintained its principles and worked the same way for a long time. This changed in the mid 20th century when the first plastic cards were introduced in 1950. This was a credit card, a completely innovative technology for that time. Later in 1966, the world’s first debit card was launched as well. However, neither one of them gained popularity until the 1990s. This was the era of credit cards and international phone calls. Cashless payments became widespread in the United States first, followed by other developed nations later, including the United Kingdom. From that period, plastic cards have become a part of our reality. We pay and get paid using them. Having one is almost a necessity for a modern human. One other thing that the global spread of the internet brought is online shopping. Yes, the talk is about web stores where almost anything can be purchased. However, mentioning online trading is also important. On Forex trading platforms, anyone is able to purchase, sell or exchange currencies. They have become so popular that authorized FCA Forex brokers are quite common these days. Plastic cards also played a crucial role in shaping the trading platforms online, as a means of payment. However, the birth of cryptocurrencies has already reduced their importance in the field.

3 BENEFITS OF HVLS CEILING FANS IN YOUR FACILITY

Описание: 3 BENEFITS OF HVLS CEILING FANS IN YOUR FACILITY Large warehouse fans can do a lot to improve working conditions at a facility. High-volume, low-speed fans have extra-long, slow-turning blades that move a great deal of air at once, which keeps facility temperatures consistent. Here are a few examples of the advantages that facilities can experience with HVLS fans: 1. COMFORT AND SAVINGS AT THE SAME TIME When it’s hot out, HVLS fans are a real relief. They stir up huge columns of air instead of just small sections, making them highly effective at cooling off anyone working on the floor. Since the HVLS fans work so well at keeping people cool, there’s less of a need for air conditioning in facilities that are equipped with these appliances. An HVAC system is still good to have, but HVLS fans will supplement it well, which can reduce the cost of cooling. For facility managers trying to find the right balance between comfortable employees and affordable heating and cooling, pairing HVLS fans with an HVAC system is a win-win. 2. WORKPLACE SAFETY Does your facility suffer from sweating slab syndrome? Many do. Sweating slab syndrome occurs when condensation builds up on cement floors. The floor becomes slippery, and workers are now at risk of falls. Equipment like forklifts may also have a hard time retaining traction. Because HVLS fans encourage evaporation, they are excellent for reducing moisture on the ground and alleviating this safety risk. Heat stress is another safety concern that facility managers should be aware of. When temperatures rise, workers need to keep themselves cool and safe. The Centers for Disease Control and Prevention recommend increasing air velocity as a way to reduce the risk of heat stress. HVLS fans are perfect for this task. 3. PEST CONTROL No facility manager wants pests in his or her building. However, some pests are tricky, especially those that can fly. Physical barriers like dock shelters or door screens can prevent creatures from flying into a warehouse, but these are most effective when paired with additional measures to keep pests out. HVLS ceiling fans can help with this issue too. Large turning blades will scare away birds, and the air movement can push bugs away as well. 3 Ways Industrial Ceiling Fans Can Benefit Your Work Environment It’s not uncommon for large, open facilities such as warehouses, barns, and aviation hangars to battle undesirable climates. These work environments can quickly become uncomfortable for employees– sometimes too hot, other times too cold– and also might be the cause of extraneous expenses for your company. When facing a facility maintenance issue of this sort, a high-volume, low-speed fan can be the ultimate solution. Originally designed for use in dairy barns to increase cow comfort, the technology has since evolved into what you see now– Large commercial ceiling fans (also called HVLS fans) that span greater than 7 feet in diameter and create small, turbulent air streams that quickly disperse and move a significant amount of air.These industrial fans are the best solution for a variety of applications in workplaces such as manufacturing facilities, distribution centers, warehouses, aircraft hangars, malls, gyms, atriums, hockey arenas, indoor swimming pools, and car dealerships. Adding this type of innovative commercial ceiling fan to your facility is going to bring you a variety of benefits, but three major ones are outlined below. Keep It Cool – with a fan Or warm. Commercial fans help balance the temperature in your space by redistributing the air that typically gets trapped at ceiling level. During the coldest times of the year, hot air is pushed back down to ground level where it is needed. In a process known as destratification, your HVLS energy-saving fan will draw heated air down and mix it with cooler air that settles near the floor. In the summer months, these industrial ceiling fans blanket a massive area, moving air to create an expansive comfort zone with an evaporative cooling effect of up to 10 degrees. And while fans don’t technically cool the air around you, the circulating air encourages evaporation, which can make people feel several degrees cooler. These commercial ceiling fans keep your employees cool, comfortable and working at their peak performance. Control Costs When you have a workspace that is temperature-regulated, by a HVLS ceiling fan, you will be able to turn your thermostat down and maintain the desired temperature while reducing energy consumption and saving money. A facility manager’s top priority is to keep everything running smoothly and ensuring the environment is right for the supplies, equipment, and employees. Your energy spend can and will be reduced with the implementation of an industrial ceiling fan. Additionally, the best commercial ceiling fans encourage evaporation while they circulate air which means excessive moisture is controlled and your facility is safer from corrosion and rust which can cause expensive damage. Protect The Environment A really, really big reason to consider adding a really, really big industrial fan to your workspace is that along with saving money, and controlling the temperature, your commercial ceiling fan will also help you protect the environment. Industrial ceiling fans can greatly reduce the amount of energy consumed by heating and air conditioning systems. When commercial fans are used in combination with a standard HVAC system, companies generally see a reduction in air conditioning usage. This means the HVAC system is using less energy and in turn, emitting less greenhouse gas thanks to the HVLS ceiling fan. Large commercial ceiling fans are typically seen as making a bold statement in a building’s design, but all you have to look at is the science behind the big fan to understand that these large fans are more than just for show and more about how they make people feel. Design is being redefined according to the human comfort of the end-user, and now more than ever, design is about helping the clients become more resourceful, resilient, and regenerative. From facilities as large as industrial warehouses to buildings as small as specialty coffee shops, large industrial fans in many shapes and sizes are being utilized—seemingly everywhere—to create environments where people want to gather and thrive. These large commercial ceiling fans help thermally equalize a space by moving air in the most efficient way possible. The fans use their long airfoil blades to move high volumes of air at low speeds, which provides a balanced airflow without the kind of disruptive air movement that could blow the hat off of your head. The end result is a gentle breeze that circulates the air, improving comfort and indoor air quality. This puts less demand on HVAC systems, reduces moisture, and, most importantly, makes the occupants of a building feel more comfortable. How Does Air Cooler Work? Air coolers, also known as evaporative or swamp coolers, cool an atmosphere by evaporating water. As air flows over water, certain particles on the water's surface are carried away. These particles take the heat with them, and this allows the air to cool. This is the main mechanism behind air coolers. Continue reading the article to know more about them. Sweating also functions in the same way: the water particles on the skin's surface bring heat away with them as they evaporate, cooling the skin. It is also known that these air coolers are able to make use of 75% less energy as compared to the central air conditioners. Evaporative coolers come in a variety of styles. A fine mist is sprayed into the air and then whipped out by a fan in some methods. Since the water in this mist is made up of fine droplets, it evaporates easily and absorbs heat from the air. In some other methods, the air is made to blow through a material that has been wetted. It can be blown through a fine mesh or past wet sheets, for example. This wet material then cools as it evaporates, and this in turn cools the air. Depending on the temperature, the air is only able to retain a certain amount of moisture. When the temperature exceeds that amount, water begins to condense out of the air at the same rate as it evaporates into it, and this leads to effectively preventing evaporative cooling. How does Air Cooler Work Without Water? Direct evaporation is used in both residential and industrial state shift coolers, which are described by an inside metal or plastic box with ventilated sides. A centrifugal fan or blower drives the air, and a water pump wets the evaporative cooling pads. Cooling units may be mounted on a building's roof, exterior walls, or windows. The fan draws in near air through vents on the unit's sides and damp pads to keep it cool. Heat in the air evaporates water from the sheets, which are continuously re-dampened to keep the cooling process going.

The Benefits and Application of Steel Pipes

Описание: The Benefits and Application of Steel Pipes Steel pipes have various advantages for your next industrial or residential project. Steel tubing is used in a variety of industries, from industrial manufacturing to sculpture. One of the applications for steel tube is in plumbing, where it is used to replace traditional plastic pipes with stainless steel pipes. Stainless steel piping is more expensive than plastic piping, but it has a number of advantages over the latter. Steel pipe buyers consider these advantages - ANTI-STAIN AND ANTI-CORROSION Corrosion is the number one adversary of metal piping. The exterior of iron, steel and concrete pipework will deteriorate due to soil and UV rays. Other types of piping inside walls appear to rust, become damaged by abrasion, or accumulate debris. However, due to corrosion resistance of stainless steel, this happens rarely. This gives stainless steel an advantage in areas such as sanitary water distribution and hospital applications. VALUE When you buy stainless steel 316 pipes, you're getting a durable product that will last for decades. It is a long-lasting substance that is simple to maintain and install. Because of its corrosion-resistant qualities, stainless steel is low-maintenance and unlikely to need to be replaced for decades. STABILITY AND ADAPTABILITY Stainless steel can be treated with various elements such as molybdenum, nickel, or nitrogen to improve its corrosion resistance. Stainless steel can endure high temperatures. By adding various materials to stainless steel, thin pipe walls can be achieved, resulting in a lighter finished product that is suited for a wide range of commercial and industrial applications. ATTRACTIVENESS Exposed stainless steel pipes and fittings are a good choice for commercial premises because the material is naturally bright and attractive. ENVIRONMENT-FRIENDLY Stainless steel is not a petroleum-based product. Unlike other pipe materials, it does not require any type of coating or lining. When you require disposing of or repairing stainless steel piping, it is 100% recyclable, reducing the environmental impact. Steel, like iron, has helped building in particular since it is a more practical alternative to other metals. Steel is corrosion-resistant, making it more long-lasting and cost-effective. It also means that, because they can survive them, these pipes can be used in regions that are constantly exposed to the elements. Steel pipes can be used for a variety of purposes. DOMESTIC BUSINESS Stainless steel 304 pipes are a popular choice in many homes since they are more durable, which means you won't have to replace them every few seasons. Any plumber would recommend stainless steel pipe for your tub, tap, and the rest of the structure, especially exposed pipes, because it is more resistant to the elements. They're also thought to be hardier. INDUSTRY OF MEDICINE If doctors use it, it must be safe, therefore that's another steel tick. Steel pipes have been utilized for everything in the medical field, including shattered bones, medical equipment, surgical tools, dental treatments, and even pharmaceutical assistance. Steel's versatility is a testament to its durability, protection, and adaptability. INDUSTRY OF CONSTRUCTION This is one of the most obvious uses for steel pipes. They are preferred by many construction companies because they are both pliable and sturdy. Steel pipes are utilized as building piles when the soil is too thin to support the weight of big structures. The structure itself, as well as its architectural style, are frequently included. In fact, construction companies are one of the major steel pipe buyers. Steel pipes are frequently used in the construction of ships, oil refineries, and even space stations, and they are housed in a shipyard. Steel pipes are a good choice for building on the ground, in the ocean, or in space. How It Works: Ball Valves A ball valve is a device with a spherical closure unit that provides on-off control of flow. Ball valves have a spherical closure unit that provides on/off control of flow. The sphere has a port (bore) through the center. When the valve is positioned such that the bore is aligned in the same direction as the pipeline, it is in the open position, and fluid can flow through it. When rotated 90°, the bore becomes perpendicular to the flow path, meaning the valve is closed, and fluid cannot pass through. Ball, butterfly, and plug valves make up the quarter-turn valve family. The most common ball valve design is two way, which enables flow to linearly travel from the inlet to the exit. Three- and four-way ball valves enable flow to travel in multiple directions, including 90° angles. Differences in ball movement Trunnion-mounted ball valves feature additional mechanical anchoring at the top and bottom on the ball. This design makes them suitable for larger-bore and higher-pressure operations as well as reduces valve torque because the ball is supported in two places. The trunnion-mounted stem absorbs the thrust from the line pressure, preventing excess friction between the ball and seats; therefore, at full-rated working pressure, operating torque remains low. CAMERON T30 Series fully welded ball valves are trunnion mounted. These ball valves deliver maximum strength and resistance to pipeline pressure and stress. Plus, their compact, spherical design also eliminates body flanges, thus reducing overall size and leak paths. Floating ball valves are attached only to the stem, not held in place by a trunnion. This sometimes causes the ball to float slightly downstream, which then causes the ball to press against the seat, creating a positive seal. Rising stem ball valves incorporate tilt-and-turn operation, eliminating seal rubbing—one of the primary causes of valve failure. When the valve is closed, the core is wedged against the seat, ensuring positive shutoff. When the valve is open, the core tilts away from the seal, and flow passes uniformly around the core face. ORBIT rising stem ball valves leverage this operating principle, delivering fast, low-torque operation and long-term, reliable performance. They also eliminate localized high-velocity flow, which can create uneven seat wear in conventional ball, gate, and plug valves. Differences in bores Full-port (fullbore) ball valves have a bore internal diameter (ID) approximately equal to the pipeline ID, which reduces friction and pressure loss across the valve and eliminates flow restrictions. This type of bore is ideal when pigging may be necessary. Reduced-port (reduced-bore) ball valves have bores that are one or two nominal sizes smaller, providing more restricted flow path that generally result in higher energy losses. Available in full and reduced ports, TK trunnion-mounted ball valves feature robust design, superior sealing, and stainless steel overlays. They are widely used in the oil and gas industry’s most severe service applications. V-port ball valves have a “V”-shaped ball or seat. Also known as control valves, they control flow velocities when the application requires. How It Works: Gate Valves Very low friction loss, saving energy and reducing cost of ownership All valves are designed to stop, allow, or throttle the flow of a process fluid. Gate valves—one of the original valve designs—are ideally suited for on-off, primarily liquid, service. A gate valve functions by lifting a rectangular or circular gate out of the path of the fluid. When the valve is fully open, gate valves are full bore, meaning there is nothing to obstruct the flow because the gate and pipeline diameter have the same opening. This bore diameter also determines the valve size. An advantage of this fullbore design is very low friction loss, which saves energy and reduces total cost of ownership. Gate and segment There are four primary designs for gate valves. Slab gate valves comprise a single gate unit that raises and lowers between two seat rings and are primarily used for transporting crude oil and NGLs. The G4N fabricated gate valve in the GROVE valves portfolio and the WKM Saf-T-Seal slab gate valve are ideal choices for this application. Expanding gate valves include two units—a gate and segment—in contrast with slab gate valves, which have one unit. The gate and segment units collapse against each other for travel and separate when the valve is fully opened or fully closed to affect a mechanical seal. Wedge gate valves are engineered with a tapered gate with metal-to-metal sealing. In contrast with a slab or expanding gate valve, wedge gate valves are not piggable because of the void that is left in the bottom of the valve body when the valve is open. These valves do not have a bore through the gate itself; instead, the gate retracts into the valve body when open, which saves height space. Knife gate valves are used to cut through extremely thick fluids and dry bulk solids. The design of this valve makes it inherently self cleaning because the knife is cleared of abrasives with each stroke as it passes the seat rings and skirts. The gate unit of this type of valve is thin compared with other gate valve types and is guided in place by the water-type body that sandwiches the gate.

How Smart Homes Work

Описание:  How Smart Homes Work When you're not home, nagging little doubts can start to crowd your mind. Did I turn the coffee maker off? Did I set the security alarm? Are the kids doing their homework or watching television? With a smart home, you could quiet all of these worries with a quick glance at your smartphone or tablet. You could connect the devices and appliances in your home so they can communicate with each other and with you. Any device in your home that uses electricity can be put on your home network and at your command. Whether you give that command by voice, remote control, tablet or smartphone, the home reacts. Most applications relate to lighting, home security, home theater and entertainment, and thermostat regulation. The idea of a smart home might make you think of George Jetson and his futuristic abode or maybe Bill Gates, who spent more than $100 million building his smart home . Once a draw for the tech-savvy or the wealthy, smart homes and home automation are becoming more common. What used to be a quirky industry that churned out hard-to-use and frilly products is finally maturing into a full-blown consumer trend. Instead of start-up companies, more established tech organizations are launching new smart home products. Sales of automation systems could grow to around $9.5 billion by 2015 . By 2017, that number could balloon to $44 billion . Much of this is due to the jaw-dropping success of smartphones and tablet computers. These ultra-portable computers are everywhere, and their constant Internet connections means they can be configured to control myriad other online devices. It's all about the Internet of Things. The Internet of Things is a phrase that refers to the objects and products that are interconnected and identifiable through digital networks. This web-like sprawl of products is getting bigger and better every day. All of the electronics in your home are fair game for this tech revolution, from your fridge to your furnace. On the next page, we'll take a look at the technology in a smart home. Smart home hub security Because smart home devices connect to the internet and communicate wirelessly, they are inherently at risk of attack. There have been several notable smart home hub security events in recent history, including: In July 2019, researchers at BlackMarble found an issue with Zipato’s ZipaMicro smart hubs where a combination of three security flaws could be exploited to open a smart lock connected to the hub. In May 2018, researchers from Pen Test Partners found a five-year-old software flaw in the Z-Wave protocol, dubbed Z-Shave, affecting an estimated 100 million chips in smart home devices sold by more than 2,400 vendors. If attacked, hackers could potentially intercept smart lock keys and unlock home doors. In February 2018, researchers at Kaspersky Lab found vulnerabilities in an unnamed smart home hub that could potentially allow remote attackers to access the server and exfiltrate user data, resulting in a potential takeover of the entire smart home system. In 2017, Rapid7 researchers found plaintext credentials stored in configuration files in the Android applications used to control the Wink Hub 2 and Insteon Hubs. Unless the phone had strong authentication, full phone encryption or used Android's built-in secure keystores, user data could be lifted from the app. In 2016, a Cognosec researcher discovered a flaw in the SmartThings Hub that could potentially allow a robber to break into a smart home by opening smart locks and jamming motion sensors. To prevent security issues within a smart home hub and entire smart home network, it is suggested to use multifactor authentication, change any default usernames or passwords, update software and firmware, and to never share serial numbers, IP addresses or other sensitive network information. The use of antimalware and avoidance of public Wi-Fi are also advised. Segmenting IoT traffic to a guest network is also an option. What is a smart switch? You’re probably familiar with those regular old light switches that you fumble for in the dark, but maybe you’re unclear on what a smart switch is. Good news: you’ve come to the right place. A smart switch is still a light switch, but with advanced features that help automate your home. They resemble traditional switches and plug into the same spaces that traditional outlets are found, except: They have radio wave capabilities that allow the switches to connect to a nearby wireless network and become part of the Internet of Things. This makes the devices “smart” and gives them an array of capabilities, including app or voice control. Their design tends to be a bit more complicated. Some may have extra buttons for more specific light control, while others may come with additional sensors or light indicators. Smart switches provide a solution for upgrading current light switches that you use every day, typically for built-in lights (as opposed to lamps, which are upgraded with smart plugs instead). Smart switches tend to cost around $50: At this price, You may not want or need to upgrade every switch in your house, but there are probably a few light switches that see very frequent use—these would make good candidates for a smart upgrade. Benefits of using a smart switch To get a better idea of how smart switches work and whether or not you want one, let’s look at the benefits and features that these switches provide. Note that other smart devices like smart bulbs also offer similar capabilities, but smart switches tend to be the most cost-effective solution if you’re already happy with your bulbs. App controls: Smart switches often come with their own smart device app, based on the brand. You can download this app and use it to control the connected light from a mobile device. This means you don’t technically have to use the switch at all, although it’s still handy to have. For example, if you’re on vacation, you could turn on your light at home so that people think someone’s home. Dimming options: Dimming does depend on the bulbs you are controlling, as not all bulbs support dimming, especially CFL bulbs. However, if your lights are compatible, most smart switches provide dimming options to control brightness until you find the levels you want. You do not need to have a dimmer installed on the actual switch on the wall. Advanced versions can automatically change brightness settings throughout the day, so you get lighter as it grows darker outside. Smart bulb control: You can control both smart bulbs and smart switches remotely, but you can also link them together in interesting ways. Program a smart switch to turn on smart bulbs through your house, and it will manage those bulbs as well as the lights that it is wired to. Scheduling: Most smart switch apps also allow you to create schedules for your lighting. This is an increasingly common way of saving energy and providing some extra convenience around the house: You can program lights to come up as you are heading home from work, for instance, or set a vacation program that only keeps a couple lights on at night for safety. Sensors: Not all smart switches have sensors, but many do. The two most common are the motion sensor, which can detect movement and turn on lights automatically (common in office buildings for energy savings), and the touch sensor that’s used as a modern way of turning the light on and controlling the dimmer. Integration with more advanced setups: Connect your smart switch to a whole ecosystem of smart devices, and you will quickly find that it can interact in a number of useful ways. You can create “scenes” with your lights that include automatic operation of multiple smart devices at one time. For example, you can connect your lights via the switch to a distant motion sensor, and have the lights turn on when motion is detected. Little scenes like these can change the way that you use your lights. What is a Motion Sensor? A motion sensor (or motion detector) is an electronic device that is designed to detect and measure movement. Motion sensors are used primarily in home and business security systems, but they can also be found in phones, paper towel dispensers, game consoles, and virtual reality systems. Unlike many other types of sensors (which can be handheld and isolated), motion sensors are typically embedded systems with three major components: a sensor unit, an embedded computer, and hardware (or the mechanical component). These three parts vary in size and configuration, as motion sensors can be customized to perform highly specific functions. For example, motion sensors can be used to activate floodlights, trigger audible alarms, activate switches, and even alert the police. There are two types of motion sensors: active motion sensors and passive motion sensors. Active sensors have both a transmitter and a receiver. This type of sensor detects motion by measuring changes in the amount of sound or radiation reflecting back into the receiver. When an object interrupts or alters the sensor’s field, an electric pulse is sent to the embedded computer, which in turn interacts with the mechanical component. The most common type of active motion detector uses ultrasonic sensor technology; these motion sensors emit sound waves to detect the presence of objects. There are also microwave sensors (which emit microwave radiation), and tomographic sensors (which transmit and receive radio waves).

What Gaming Chairs do Pros Use?

Описание:  What Gaming Chairs do Pros Use? You may wonder if they use these pro gaming chairs for the sole purpose of appeal or if they serve any other purpose as well. TO answer that in brief, they sure serve a purpose beyond fancy looks. Even though these chairs add up to great overall aesthetics, they are beneficial for long hours of gaming, competing in a gaming competition, and daily long streaming sessions as they are designed ergonomically. They reduce the stress your back and arms take so when you game for long hours; your body does not take a toll. Streamers and professional gamers often have to sit in the same chair for hours every day, and as we all have experienced, we go from a straight sitting position to a reclined one within the first hour. This can cause backache and shoulder pain in the short term; in the long term, it can cause permanent back problems, muscle damage etc. And when your main job is to sit in the same position every day for hours, like that of streamers, then it can start affecting your body pretty quickly. A good seat is a racing essential, but there is a lot to know if you want to pick the right seat. This buyer’s guide is meant to help you get started, answering your questions to make sure you are making the right purchase. There are a lot of options, after all, and in the end, you need to make sure you’re asking yourself the right questions. The chair has 20 years of innovation put behind it, making it one of the most comfortable. It has refined tilt mechanism, adjustable Posture Fit SL, and 8Z Pellicle suspension. You have 3D armrest support for your arms. Aeron is not a one size fit all, so it comes in three different sizes. One thing you might notice is that it does not have lumbar support, that is because the ergonomics are so advanced that you don’t need one. It does not come with all flashy racing colors but with a mesh on the back which makes long hours of sitting comfortably on your back as well as skin. So, if you are someone who likes to keep their set up minimal and but does not like to give up on comfort, then Aeron is the chair for you. Check our detailed Herman Miller Aeron Review before deciding if it’s best for you. If you have more questions about racing seats that haven’t been addressed, feel free to comment, and we’ll add your answer to this guide when we can. When and why is a racing seat recommended? A racing seat is recommended in a track setting, particularly in a car that isn’t used on the road. Any dedicated racecar should be fitted with a racing seat. A racing seat is meant to hold the driver in place. This increases driver control, providing a better grip on the steering wheel and better foot placement on the pedals. Better driver control means faster laps. Racing seats are about safety. They are meant to protect you in the event of a crash. A good racing seat can prevent or lessen injuries, and even save your life. Sanctioning bodies require specific standards when it comes to the racing seat you use in your car for just this reason. In many instances, racing seats also have the added benefit of weight savings. What features are most important when choosing a seat? First and foremost, you want the seat to comply with the rules and regulations of your track or sanctioning body. Make sure you know the rules and choose a seat accordingly. The type of racing you’re doing will dictate what type of seat you choose. Pick a seat with the proper support, good construction, and keep in mind any driver needs. Just as with helmets, and racing suits, certification is important. Look for FIA or SFI approved seats to make sure they’re up to the standards of safety for the type of racing you’re doing. What Are the Different Types of Forklift Seats? There are several different types of forklift seats available as direct factory replacements or as upgraded seating. They include ultra-soft forklift seats designed for comfort and tilt-up models that offer little in cushioning, but plenty in the ability to tilt up to remove rainwater from the seat. Many models and styles of forklift seats are similar to other models, with only a small differentiating feature of the seat to differentiate the seat from others. Some seats offer leg and shoulder protection in the event of a rollover, while others provide high-back neck and head protection.One of the most uncomfortable features of the forklift, for many operators, is the seat. Many of the original forklift seats are manufactured from very hard foam to increase the seat's durability, and sitting on this type of seat for an extended period of time can be very uncomfortable. Replacing hard forklift seats with softer versions can not only increase employee morale, it can reduce injuries related to the unforgiving nature of the stock seat materials. Even the slightest bump can be transmitted through the hard seat and into the hips and spine of the operator, creating sore spots and injuries.Some forklift seats are available on a swiveling base to allow the operator to get on and off of the machine without twisting the torso, which can result in injury. The use of swiveling seats can also eliminate the possibility of banging the operators' knees into the steering gear and creating injuries. Choosing forklift seats that have adjustable tracks under the seat can provide comfort options for different-sized operators. This can also convert into better control and better operation of the forklift by placing the operator in a more comfortable seating position to the steering wheel, foot pedals and other mast controls.Seats equipped with armrests can also offer the operator a more comfortable operating posture. The arm rests can be used to place an inventory sheet on as the operator fills a specific order. When used in cold climates, electrically heated seating can often allow an operator to work much longer between breaks, thereby increasing the productivity of the operator during a typical shift. No matter the reason for changing forklift seats, the ultimate goal is often to provide a more comfortable machine for an operator to work from. This equates to less down time due to poor blood circulation in the legs and feet, as well as increased safety by allowing the operator to have better visibility from a seat that can be appropriately adjusted to suit her. Integration of semi-active devices in Automotive Seating System (ASS) with intelligent control policies help attenuation of the vibration transmitted to the occupant. The current work investigates the effectiveness of a semi-active magnetorheological (MR) damper with ASS for a quarter car model with the application of suitable control algorithms. The system controller calculates the desired damping force using proportional integral derivative (PID), skyhook on/off, PID tuned using genetic algorithm (GA), skyhook continuous and modified skyhook controllers. The signum function damper controller estimates the command voltage required for tracking the desired damping force. The displacement and acceleration of the passive seat system was compared with the semi-active seat suspension system in time and frequency domains. The results from the frequency domain shows that the lowest resonance peaks for the seat system can be achieved using the modified skyhook control policy. The effectiveness of the modified skyhook controller is evaluated in terms of peak to peak (PTP) acceleration, root mean square (RMS) acceleration, frequency weighted RMS acceleration, seat effective amplitude transmissibility (SEAT), vibration dose value (VDV) and crest factor (CF) for enhancing the ride quality. The modified skyhook controller can dissipate the energy better than the passive system. The modified skyhook controller increased the occupant ride quality of SEAT, VDV and CF by 30.41%, 52.84% and 11.62% on account of small bump excitation and 31.76%, 53.27% and 11.02% on account of large bump excitation compared with passive system. The modified skyhook control policy attenuates the vibration better than other control policies addressed in this paper. ? 2019, Springer-Verlag GmbH Germany, part of Springer Nature. The most common type of fabric used in homecare equipment is nylon, since it is slightly less expensive than vinyl, especially when purchased as replacement upholstery. Nylon, a synthetic fabric, is somewhat porous, and offers breathability when a patient sits. It is used commonly on ultralight, lightweight and rehab wheelchairs that are usually more expensive overall than standard wheelchairs, due to its porous nature. Nylon takes longer to reach maximum body heat reflection, thus insulating the user better than vinyl. A downside is that nylon is harder to clean. Because it is so porous, it absorbs more liquids like body fluids, which it almost permanently retains. This translates into more frequent upholstery replacement depending on the continence needs of the user, or other issues. Vinyl: Here’s What You Should Know Vinyl is also a synthetic material. It was created to simulate leather. That’s why it is also known by another nickname: leatherette. Vinyl is a non-woven material that is normally used in hospital settings. It is non-breathable since it is not porous. As a result, it tends to be warmer than nylon, causing patient perspiration, since it does not allow airflow or ventilation. Vinyl, a slightly more expensive material than nylon, is used for almost all standard wheelchair upholstery. Colors vary by manufacturer, with black and navy blue the most common. Vinyl upholstery comes in a much broader color range than nylon. Health Considerations to Keep in Mind As people age, they lose skin collagen and elastin, decreasing the skin’s tensile strength and making it more susceptible to tears or wounds. Also, this contributes to circulatory issues like the advance of vascular atrophy. If an individual uses a wheelchair for most of their mobility needs, they will have a tendency to develop pressure ulcers due to skin deterioration or muscle loss and pressure on extremities. All of these issues should be points of discussion with a medical professional in the decision process for what type of wheelchair seat to get, along with the type of upholstery material used on the wheelchair. Caring for Your Graham-Field Wheelchair Normal wear and tear will cause all seat and back upholstery to stretch on a wheelchair. Room temperature does not affect nylon, so it takes longer to stretch than vinyl does. Vinyl is affected by temperature changes, and with normal wear and tear, vinyl seat and back upholstery will tend to stretch naturally, and much faster than nylon does. The most important decision factor in choosing your wheelchair’s upholstery, though, is how easy the fabric is to clean and maintain from a hygiene standpoint.

Understanding the role of inductors in power electronics

Описание: Understanding the role of inductors in power electronics Inductors are typically used as energy storage devices in switched-mode power devices to produce DC current. The inductor, which stores energy, supplies energy to the circuit to maintain current flow during “off” switching periods, thus enabling topographies where output voltage exceeds input voltage. Due to the way they work—by not only altering electric field but the magnetic field around it—many people struggle to understand them. What is an inductor? An inductor is arguably the simplest of all electronic components. It’s a passive two-terminal electrical component that stores energy in a magnetic field when electric current flows through it. Typically, an inductor will consist of an insulated wire that’s wound into a coil, much like a resistor. This design was settled on following extensive trial and error methods that considered methods like Hanna curves and area-product. When the current flowing through the coil changes, the time-varying magnetic field induces voltage in the conductor with a polarity which opposes the change in current that created it. As such, inductors oppose any changes in current that pass through them. The induced magnetic field also induces an electrical property known as inductance—the ratio of voltage to the rate of change of current. Inductance quantifies how much energy an inductor is capable of storing. Inductor design and key components The design of an inductor is governed by electrical, mechanical, and thermal requirements of a given application. In general, it involves: Selecting the core material Deciding a core shape and size Selecting a winding wire The core material is an enamel-coated magnetic wire typically made of copper which is then coated in layers of insulating polymer material. The winding can form many shapes, including circular, rectangular foil, and square cross-section. A magnetic wire is chosen to confine and guide the magnetic fields, and this is insulated to prevent problems like short circuits and breakdowns. The different types of inductor Different applications require different types of inductor. In almost all cases, you’ll find that an inductor in a system is formed around a core material—generally iron or iron compounds—to support the creation of a strong magnetic field. Iron core inductors Iron is the classic and most recognizable magnetic material, making it the perfect choice for use in inductors. As above, iron in inductors takes the form of an iron core. They are typically used for low frequency line filtering due to their relatively large inductances. They are also used a lot in audio equipment. Inductors don’t always need to have an iron core, though. Air core inductors As the name suggests, air core inductors have no core—the core is open air. Since air has a low permeability, the inductance of air core inductors is very low. This means that the rate of current rise is relatively fast for an applied voltage, making them capable of handling high frequencies found in applications like RF circuits. Ferrite core inductors A ferrite is a ceramic material made by mixing and firing iron(III) oxide blended with small amounts of one or more additional metallic elements, such as nickel and zinc. When used in inductors, ferrite powder is mixed with an epoxy resin and molded to form a core around which a magnetic wire can be wound. Ferrite inductors are the most widely used type as it’s possible to finely control their permeability by tuning the ratio of ferrite to epoxy. power inductors A coil is a generic name for an electrode in the shape of a spiral. Among the different types of coils, there are coils called “inductors” which are used for electrical applications. Inductors can be further categorized into RF inductors used for signal processing, and power inductors for power supply lines. The power inductors discussed in this section form part of the voltage conversion circuit in a DC-DC converter or other device. Here we will explain the operation of a power inductor in a DC-DC converter. A power inductor is used in a step-up, step-down, or step-up/step-down circuit to convert a certain voltage to the required voltage. Among those different circuits, it is primarily used in a type of circuit called a “switching regulator.” Figure 1-1 shows an example of a switching regulator step-down circuit. It uses an IC, power inductor, and capacitor to convert a DC input voltage to the required output voltage. The power inductor works with the capacitor to play the role of rectifying the rectangular wave output from the IC to a direct current. If either one of these components is missing, the output cannot be properly rectified. What is a transformer? A transformer is a device that transfers electric energy from one alternating-current circuit to one or more other circuits, either increasing (stepping up) or reducing (stepping down) the voltage. Where are transformers used? Transformers are employed for widely varying purposes. For example, a transformer is often used to reduce the voltage of conventional power circuits to operate low-voltage devices and to raise the voltage from electric generators so that electric power can be transmitted over long distances. Why is the iron core of a transformer laminated? The iron core of a transformer is laminated to reduce eddy currents. Eddy currents are the small currents that result from the changing magnetic field created by the alternating current in the first coil. They need to be minimized so they won’t disturb the flow of electricity from the primary coil to the secondary coil. transformer, device that transfers electric energy from one alternating-current circuit to one or more other circuits, either increasing (stepping up) or reducing (stepping down) the voltage. Transformers are employed for widely varying purposes; e.g., to reduce the voltage of conventional power circuits to operate low-voltage devices, such as doorbells and toy electric trains, and to raise the voltage from electric generators so that electric power can be transmitted over long distances. Transformers change voltage through electromagnetic induction; i.e., as the magnetic lines of force (flux lines) build up and collapse with the changes in current passing through the primary coil, current is induced in another coil, called the secondary. The secondary voltage is calculated by multiplying the primary voltage by the ratio of the number of turns in the secondary coil to the number of turns in the primary coil, a quantity called the turns ratio. Operation Current transformers are unique because they usually have only one winding. The primary is connected to the line load in series. When the primary has a high current rating, the primary winding may be a straight conductor that runs through the magnetic circuit's center. This straight conductor indicates a one-turn winding.  When the primary has a low current rating, the primary winding may consist of several turns wrapped around the core. This provides the required flux on low-current applications or to compensate for line drop to a power meter. The secondary consists of many turns of wire wrapped around a core. The number of turns is determined by the desired turns ratio of the current transformer. The primary current of a current transformer is not controlled by the secondary, as it would be in a two-winding potential transformer. The secondary of a current transformer cannot affect the current in the primary, as the load on the feeder determines the primary current. When the primary circuit is energized, the secondary of a current transformer must never be left open. When the circuit is operational, the load on the secondary maintains low magnetizing currents and thus low turn-to-turn potentials. When the secondary becomes an open circuit, the magnetizing currents rise, and the current transformer acts as a step-up potential transformer. The voltage can rise to a destructive level and cause a short between the turns as the result of the degradation of the insulation. Therefore, a current transformer should always have its secondary shorted when not connected to an external load. What is a High Voltage Transformer? A high voltage transformer is a type of transformer that operates at a high voltage level. High voltage transformers are normally used in high voltage labs for testing purposes. These high voltage transformers are subjected to transient voltages and surges during their normal operation when the insulation under test breaks down. To withstand these impulse voltages, the insulation of these transformers must be carefully designed. These are usually single-phase core-type transformers. This type of transformer is generally oil immersed. Bakelite sheets are used for separating high tension and low tension windings. The high voltage transformers used for HV cable testing also need to supply sufficient electric current. This can generate a lot of heat, and as such the cooling system of these transformers is very carefully designed. Special care also needs to be taken to ensure proper transformer voltage regulation. For insulator testing purposes, the required current is very less but, while the insulator breaks down during testing, there would flow huge current through the transformer. To limit this current, a high resistance is connected in series with transformer.

The Leather Knife Roll Designed by a Chef

Описание: The Leather Knife Roll Designed by a Chef You can tell a lot about a chef from their knife roll. Unfortunately, from what we hear often, finding a high quality knife roll to protect chefs’ knives doesn’t seem like such an easy task. That’s probably why this beautiful leather knife roll has got so many chefs excited. Called the “perfect storage tool” by Food & Wine, the beautiful piece of kit is part of a collaboration between an award-winning chef, an artisan blacksmith and some outdoor gear craftsmen. “Durability, balance and comfort” were the three key attributes that chef Chris Hastings (Hot and Hot Fish Club and OvenBird) looked to incorporate in the leather knife roll, and working together with Radcliffe Menge, the founder of Tom Beckbe, Alabama-based outdoor apparel company, they came up with the perfect piece of gear for professional chefs. It comes in a full-grain vegetable tanned leather that is durable and elegant, and it is functional with space for 18 knives and eight additional pieces of hardware. Adjustable shoulder straps make this high quality roll bag comfortable and ergonomic. The key feature of the knife roll is that it is balanced – knives are placed on both sides so the blades cross over one another in opposing pockets. A three-part interior flap system and two exterior belts make sure knives are secure.If you want to fill up your new leather knife roll with a set of equally good-looking knives - and have US$2,499 to spare - check out the limited edition chef knives also available on their website. Hastings and Menge teamed up with Will Manning, the blacksmith of Tennessee knife brand Heartwood Forge, who created the set that includes three knives - an elongated paring knife, a traditional chef’s knife and a cleaver-like knife that Menge calls the Butcher’s Haste. Most slitter blades feature a beveled edge for optimal cutting power. A beveled edge allows a blade to slit material instead of creating standard cuts. When a slitting knife has the primary purpose of making punctures, it will have teeth. These teeth create smaller slits in progression, such as the ones found on tear-off paper products. Our sales engineers can help you determine which blade solution will work best for your application. At York Saw & Knife, we manufacture all of our slitter blades in-house.

Their sharpness and durability allow you to work with a wide range of synthetic materials. And more This list includes just a few of the possible applications for slitting knives. Thanks to our versatile capabilities, you can specify a slitting blade design for a variety of uses. Long blade knives In this article, we will introduce you to knives that have a blade length of at least 20 centimetres. It is obvious that long blades are particularly well-suited to larger ingre-dients, but these knives excel in different areas too, as you will find out: Super Slicer: the cut-anything knife There are some ingredients that demand a truly exceptional knife: the tough skin of a pineapple, for example, or the stalk of an artichoke. And the Super Slicer can easily handle both: the convex, outwardly shaped serrations of the blade ensure pow-erful and clean cuts - even with very fibrous, tough foods. Salmon knife: sharp and flexible Granted, there isn’t always a suitable knife for every possible situation. But, if you have a whole salmon in front of you, or at least half of one, you'll love this blade. The Salmon knife is very long, sharp and flexible, so you don't tear the fine flesh of the fish and you can cut wafer-thin slices. Ham knife: also suitable as a carving knife Of course we have the right speciality knife in our range when it comes to smaller hams. Thanks to its long, narrow blade, the Ham knife is also suitable as a carving knife, as you can use it to carve up roasts, hams or poultry – whether raw or cooked – very efficiently. How to choose the suitable material for cutting knife blade of industrial shredders Shredder blade is a kind of cutter that is equipped on industrial shredder or granulator. They are machines for crushing waste materials like rubber, tires, wood, paper, polymers, plastic, textiles and so forth. As we all know, industrial waste shredders are playing a critical role in the recycling industry. For one thing, they can save a lot of storage space. Data indicates a shredder can reduce the total volume of processed industrial waste by 30%-50% on average. For another thing, shredders optimize the value of industrial wastes by forming them into granule reaching a recyclable level. As space is limited, we only pay attention to the cutter part of a shredder. Many variables to affect shredder cutter’s efficiency, such as cutting angle, numbers of knives, cutting velocity, chip load, etc. Above all, A primary factor is If the cutter material is suitable to deal with the industrial waste. That’s always the first thing on your concern. Materials of shredder cutter out there vary, so do the materials of industrial waste, too. Common trash wood includes cardboard, paper, solid wood, and plywood board. For brittle wood, such as branches, twig, cardboard, SK5 is a practical and economical option. The steel is a kind of carbon tool steel with nice resistance to wear, but poor plasticity and hardenability. SK5 is often used to make woodworking knives, and sample-sized dies. Its performance is not super outstanding, which results in its cheaper price, compared with other types of wood-processed steels. However, for high-strength trash wood, such as stumps, plywood boards, and discarded furniture, SK5 is not competent. We’d turn to use high manganese steel, accordingly. High manganese steel is generally used to make a smashing hammer in mining and architecture industry. Its metal hardened depth can reach 10mm-20mm and remain as hard as HB500-550. When working at a high torque, the manganese steel will not be easily deformed or even broken like SK5. In addition to this, the high manganese steel is more affordable, compared with other alloy carbon steel. 2.For shredding plastic In the plastic industry collectors and recyclers started their business pretty late compared to areas of scrap wood and paper&cardboard. Trash plastic can be generally a huge blend with at least the same amount of possible additives and fillers. They contain not only lower grade plastic but also high-value ones. Thus we need to recognize which type of plastic is in the input mixture. The principle of the crusher blade is to use a set of running knives to smash the target (pulverized material). When the target (pulverized material) is broken by the crusher blade, the blade is gradually worn out. There are many applications at different industries which are using crusher knives . Therefore, Jiuli Knives will base on the client's application to select the right material to produce the crusher blade, and it will influence the wear resistance and toughness of the crusher knife to be optimized, the product life of the blade to be increased, the pulverizing ability to be maximized and the thickness of the pulverized powder is uniform. The slitter rewinder blades are mainly applied to rewinders for slitting of tissue paper. The quality of rewinder blades directly affect the production quality and efficiency. Seton developed circular tungsten carbide and inlay carbide rewinder blades to improve customers' use effect and blades' service life. As for the selection of cutting tool materials, we can make recommendation according to customers' cutting materials, so as to ensure that customers can use the appropriate knives during production. The common specifications of blades may be not suitable for your machines, and if needed, please send us the samples or drawings. We will manufacture strictly in accordance with the design precision.

Benefits of CNG

Описание: Benefits of CNG Environmentally Friendly, Reduced maintenance cost, CNG Produces significantly less Pollutants than petrol/diesel, natural gas is cheaper & safer than Petrol/diesel, Green fuel. Greenfuel: Commonly referred to as the green fuel because of its lead and sulphur free character, CNG reduces harmful emissions thus reducing the effect of global warming. Being non-corrosive, it enhances the longevity of spark plugs. Due to the absence of any lead or benzene content in CNG, the lead fouling of spark plugs, and lead or benzene pollution are eliminated. Safety: CNG is less likely to auto-ignite on hot surfaces, since it has a high auto-ignition temperature (540 degrees centigrade) and a narrow range (5%-15%) of in flammability. It means that if CNG concentration in the air is below 5% or above 15%, it will not burn. This high ignition temperature and limited flammability range makes accidental ignition or combustion very unlikely. Low operational cost: The operational cost of vehicles running on CNG, as compared to those running on other fuels, is significantly low. At the prevailing price of fuel in Delhi, Operational cost of CNG vehicles is 66% lower than petrol and 28% lower than diesel.
