Air compressor function and use

1, can be used as aerodynamic

after compression, the air can be used as power, mechanical and pneumatic tools, as well as control instruments and automation devices, instrument control and automation devices, such as tool replacement of machining centers.

2, can be used for gas transmission

air compressors are also used for gas pipeline transportation and bottling, such as remote gas and natural gas transportation, chlorine and carbon dioxide bottling.

3. For gas synthesis and polymerization

in the chemical industry, some gases are synthesized and polymerized by increasing the pressure of compressors. Such as atmosphere and hydrogen synthesis of helium, hydrogen and carbon dioxide synthesis of methanol, carbon dioxide and ammonia synthesis of urea. And add high pressure to produce polyethylene.

4. For refrigeration and gas separation

the gas is compressed, cooled, and expanded by an air compressor and liquefied for artificial refrigeration. This type of compressor is usually called an ice maker or ice machine. If the liquefied gas is a mixed gas, each group can be separated separately in the separation device to obtain various gases with qualified purity. For example, the separation of petroleum cracking gas is first compressed, and then the components are separated separately at different temperatures.

Extended Data

the full name of the air compressor is air compressor (English: air compressor), which is the main body of the air source device. It is a device that converts the mechanical energy of the prime mover (usually an electric motor) into gas pressure energy. It is a pressure generating device for compressed air.

There are many types of air compressors, which can be divided into positive displacement compressors, reciprocating compressors, and centrifugal compressors according to their working principles.

Now commonly used air compressor piston air compressor, screw air compressor, centrifugal compressor and sliding vane air compressor, scroll air compressor.

Screw air compressor is a kind of positive displacement compressor. The compression of air is achieved by the volume change of the cogging grooves of the male and female rotors that are equally meshed with each other in the casing. The male and female rotors rotate in the casing that is precisely matched with it, so that the gas between the rotor teeth continuously produces periodic volume changes and pushes from the suction side to the discharge side along the rotor axis, completing the suction, closed transportation, Compression, exhaust and other working processes.

The scroll compressor is formed by the intermeshing of two dynamic and static scrolls with two double function equation type lines. In the work process of suction, compression, and exhaust, the static disk is fixed on the frame, and the moving disk is driven by an eccentric shaft and restricted by an anti-rotation mechanism. It rotates on a plane with a small radius around the center of the static disk base circle. The gas is sucked into the periphery of the static disc through the air filter element. With the rotation of the eccentric shaft, the gas is gradually compressed in several crescent-shaped compression chambers formed by the static and dynamic disc, and then continuously sent out by the axial hole of the central part of the static disc.
