Air compressor can be used in various industries

Air compressor is used in electric power, textile, steel, food, pharmaceutical, breathing, diving, fire, electronics, machinery, equipment, automobile, packaging, printing, toys, chemical, energy, glass, environmental protection, hardware, PET bottle blowing, ship, military and other aspects.

1. Compressed air as power:

A total of all kinds of pneumatic machinery are driven. The exhaust pressure of pneumatic tools is 7-8kg/cm2, which is used to control instruments and automatic devices. The pressure is about 6kg/cm2, the vehicle is automatic, the doors and windows are opened and closed, the pressure is 2-4kg/cm2, the stirring pressure in the pharmaceutical industry and brewing industry is 4kg/cm2, and the weft blowing pressure in the air jet loom is 1-2kg/cm2, the starting pressure of medium and large diesel engines is 25~60kg/cm2, the pressure of oil well fracturing is 150kg/cm2, the pressure of "secondary method" oil recovery is about 50kg/cm2, and the pressure of high-pressure blasting coal mining is about 800kg/cm2, and the pressure compressed air in the national defense industry is its power. The ups and downs of submarines, the firing and driving of torpedoes, and the salvage of sunken ships are all powered by compressed air at different pressures.

2. Compressed gas is used for refrigeration and gas separation:

gas is compressed, cooled, expanded and liquefied, used for artificial refrigeration such as ammonia or freon compressor. Its compression pressure is mostly 8 to 12kg/square centimeter, and this type of compressor is usually called a "refrigerator" or "ice machine". In addition, if the liquefied gas is mixed gas, the components can be separated separately in the separation device to obtain various gases with qualified lip reading. Such as air liquefaction can be obtained after separation of pure oxygen, pure nitrogen, and pure xenon, krypton, argon, helium and other rare gases.

3. Compressed gas for synthesis and polymerization:

in the chemical industry, gas compression to high pressure, often favorable synthesis and polymerization. For example, nitrogen hydrogen synthesis of ammonia, hydrogen and carbon dioxide synthesis of methanol, carbon dioxide and ammonia synthesis of urea. In the chemical industry, for example, the pressure of high-pressure polyethylene reaches 1500-3200kg/cm2.

4, compressed gas is difficult about oil hydrogenation refining:

in the petroleum industry, hydrogen is heated by artificial methods and reacted with oil after pressurization, which can crack the heavy parts of hydrocarbons into light components of hydrocarbons, such as the lightening of heavy oil and the hydrofining of lubricating oil.

5. Gas delivery:

compressors used for piping gas whose pressure depends on the length of the pipe. When sending remote gas, the pressure can reach 30kg/cm2. Chlorine bottling pressure is 10~15kg/square centimeter, carbon dioxide

the bottle pressure is 50-60kg/cm2.
