Axial Flow Fans date back to the horizontally configured windmills of Europe in the Middle Ages. The first electrically powered fans, introduced in the 1880s, were axial fans. Axial fans are named for the direction of the airflow they create. Blades rotating around an axis draw air in parallel to that axis and force air out in the same direction. Axial fans create airflow with a high flow rate, meaning they create a large volume of airflow. However, the airflows they create are of low pressure. They require a low power input for operation. http://www.dhlcentrifugalfan.com/axial-flow-fan/

A carton machine will pick up a single piece from a stack of fold carton and then get it to stand up straight, or erect. The machine will fill it with a product or a number of products horizontally through an end that is open, and then close it by tucking an end flap of the carton or putting on glue or adhesive. It is not that hard to understand, but for those who aren’t involved in the cartoning field, it can be a little tricky to understand if they haven’t seen one first-hand in action. http://www.kdpackmachine.com/cartoning-machine/

Further classifications might be by size. For instance, miniature linear bearings might work well moving a biologic slide sample just a few millimeters beneath a microscope lens while industrial-bearings on injection molding machines carry tooling of several tons. Bushings provide possibly the simplest linear bearing. These thin-walled cylinders can be injection molded of proprietary polymers infused with a lubricant. An oil-infused bronze design, also cylindrical, rides on a polished round rod. This linear-bearing classification is often referred to as slides. http://www.lsyongrun.com/sbr-rail-and-block/

Since greater cell density results in increased surface area, this means that a metal substrate of a given volume will be more catalytically active than a ceramic one. Most metal substrates used in the cooking and heating sectors have between 100 and 200 cells per square inch (cpsi). Metal substrates can be made in a variety of profiles, with round, square and rectangular being most common. Another variable is the pattern of the corrugations in the foil, which can either be straight through or involve changes of direction. http://www.sheungwell.com/auto-exhaust-purification/metal-honeycomb-substrate/

There are various methods and technologies to store various forms of energy. The choice of energy storage technology is typically dictated by application, economics, integration within the system, and the availability of resources. And they are often used as Residential Energy Storage System or Commercial Energy Storage System for Outdoor Power Supply. Energy storage systems are also involved in converting energy from forms that are difficult to store to forms that are more convenient or economical. http://www.suntrver.com/residential-energy-storage-system/

Another popular knitting machine is Shoes Upper Knitting Machine, which is mainly circular knitting machine. Compared to warp knitting machines, circular knitting machines create shoe upper material that offers better breathability, more design possibilities and less waste. Even when used for more casual physical activity, athletic shoes must be designed in a way that keeps feet cool and dry. Because of this, the vast majority of shoe upper material is made using spacer fabric. http://www.tckjknittingmachine.com/shoes-upper-knitting-machine/

Simply put, roller conveyors are a form of conveyor belt that utilizes rollers - evenly-spaced rotating cylinders - to allow objects to skate across its surface. They move material from one place to another destination, and often leverage gravity or implement small motors to do so. The transported material must have a rigid riding surface that is supported by a minimum of three of the rollers. http://www.wxhq-group.com/roller-conveyor/

Fire doors are an engineered component which includes the frame, door leaf and any fixtures and fittings. They can be solid or made with a special core, often flax board or a wood composite material. They will be fitted with intumescent seals, installed in the frame or leaf, which seal the door on impact with heat to stop the spread of fire and/or smoke around the edges of the door. Doors will similarly be fitted with smoke seals to prevent the passage of smoke in the early stages of a fire. http://www.firedoorfactory.com/fire-door/wood-fire-door/

Your timing belt is responsible for keeping your engine's various components working together in synchronization. Because it is made of rubber, it will stretch and crack overtime. A slipped timing belt can cause engine misfiring and a completely severed timing belt can cause a complete engine breakdown. Just like all the other belts in your vehicle that provide power to other major systems like your ac compressor and your power steering pump, the upkeep of these belts is extremely vital to your vehicle's systems running safely and efficiently. http://www.goodwillrubber.net/automotive-rubber-parts/

Wear Pipelines Layer is a seamless steel pipe, and the inner layer is alumina ceramics. Ceramic liner layer hardness is up HV1100-1400, which is equivalent to tungsten carbide cobalt. The wear resistance performance is 20 times higher than carbon steel tubes. Alumina Ceramic Sheet Wear-resistant Tube can resist industrial wear problem mainly by a few millimeters thick corundum inner layer, which is much better than alloy steel pipe and cast tube resisting by both composition,organization and thickness. http://www.hznmpipeline.com/alumina-ceramic-sheet-wear-resistant-tube/
