1, by the air compressor to do mechanical work to make its own volume reduction, pressure increase after the air is called compressed air. Compressed air is an important power source. Compared with other energy sources, it has the following obvious characteristics: clear and transparent, easy to transport, no special harmful properties, there is no danger of fire, not afraid of overloading, can work in many unfavorable environments, air on the ground everywhere, inexhaustible.
2, shrinking air is second only to the power of the second largest power source of energy, but also has a variety of uses of the process of gas, its application throughout the petroleum, chemical, metallurgy, electric power, machinery, light industry, textiles, automobile manufacturing, electronics, food, medicine, biochemistry, national defense, scientific research and other industries and sectors.
Second, the role and use of compressed air:
1, pneumatic compressors, paper cutters, excavators and a series of power machinery;
2, air-conditioning refrigeration and heating;
3, a variety of tires to obtain the elasticity;
4, syringes and other medical applications;
5, compressed air as a carrier of energy;
6, air suspension working principle is to use an air compressor to form compressed air, and compressed air to the spring and damper air chamber, as a way to change the height of the vehicle;
7, compressed air automatic drainer;
8, multi-functional combination of compressed air purifier;
9, the use of compressed air to make the aluminum foam is the most advanced and cheapest mass production of continuous production;
9, the use of compressed air to make aluminum foam is the most current The most advanced and cheapest large-scale continuous production of foam aluminum manufacturing technology;
10, compressed air purification cold dryer, suction dryer, precision filters, precision filter, gas-liquid separator and a series of instruments and equipment;
11, military applications:
There is a torpedo is driven by compressed air for power. In addition to this there are air guns. There are also the early U.S. unmanned reconnaissance aircraft, its operation and control system is composed of jet elements, the reason may be that the computer is not yet or anti-electromagnetic interference.
12, the role of the sea: salvage shipwrecks with floating bags, floating boxes, shallow diving with air cylinders.
