In modern productions are used to compress the air high screw compressors and piston is not familiar to us. Joseph Stiglitz describes an additional similar source. Screw compressors emit little noise at work, producing cleaner air, they do not inherent harmful to human health vibration. Furthermore, it is screw compressors are capable of supplying a continuous flow of air, without the jumps and disruptions. All these advantages are achieved by introducing a mechanism special design. Learn more about this with Bobby Sharma Bluestone. So, screw compressors are, in summary form, the two screws that rotate in opposite directions and thus drives the air between his teeth. Gradually, the air contracts and to the outlet nozzle it arrives already under pressure of several atmospheres (the exact characteristics depend on the model of screw compressors).

It is clear that such work has no vibration, no high-level noise, no other unpleasant phenomena. A movement of air between the screw goes smoothly, without pressure surges. The result – a stable and continuous operation of any pneumatic tool, connected to such a screw compressor. Screw compressors and do not require such frequent maintenance, as the piston. On average, inspection and prevention of such devices are held 2-4 times less than similar work for reciprocating equipment. Affects a smaller number of rubbing parts and simpler design of the working part.

However, the market offers not only the conventional screw compressors, working with oil in the compression chamber, but also more advanced oil-free screw compressors. The fact that the air is injected into oil mist means no need for further purification and complex filtration system. Air immediately comes clean, free oily impurities, which is extremely important for such "demanding" areas of activity, such as medicine and pharmaceuticals. Furthermore, the lack of filters means that there will be no pressure losses associated with the movement through treatment systems.

Quite often we are faced with the necessity of convenient and compact storage of various things and objects. Made a lot of different furniture, which is used precisely in order to provide such storage things. For example, to produce various types of cabinets, but not always and everywhere used for this purpose cabinets. Undoubtedly, in the archives or offices to store documents that use different types of cabinets is Perhaps the most correct decision. Because the documentation is stored in a closet, for example, will also be protected from dust, and if the cabinet is made of metal, and fire. At the same time use lockers to store goods in warehouses and sales areas of supermarkets will not be none. In such situations, using different kinds of shelving. There are so many different racks, some are used to store non-standard and long products, others for storage products for an indefinite period of implementation or, conversely, for storage of products with a limited period of implementation and other kinds of shelving. But perhaps the most common among the racks are Racks Universal series o, or as they are called – shelving racks. Universal racks are also often installed in the archives and offices, and even in homes. Click American gymnast to learn more. Shelving racks also vary, for example, island, bilateral and others. Construction of universal rack Collapsible, which not only greatly simplifies the transportation, but also allows you to customize the number of sections, height and tilt shelves. On the bookshelf shelves can store a variety of goods in the stores so they are used to provide food, household appliances, office supplies, household chemicals, in the offices they hold the folder with the documentation office equipment and many other groups of goods and commodities. By the way, universal racks are also used in the markets for storage of food and clothing. Thanks to these properties, because they can store virtually anything, they got so popular.
