The specific application of air compressors in various industries? Air compressors are widely used in electric power, textile, steel, food, pharmaceutical, respiratory, diving, fire, electronics, machinery, equipment, automotive, packaging, printing, toys, chemicals. , energy, glass, environmental protection, hardware, PET blowing, shipping, military and other aspects.

1. Compressed air as power:

A total of a variety of pneumatic machinery, pneumatic tools exhaust pressure of 7 ~ 8 kg / cm2, used to control instruments and automation, pressure is about 6 kg / cm 2, the vehicle is automatic, doors and windows open and close, pressure is 2 ~ 4 kg / cm 2 , the pharmaceutical industry, the mixing in the wine industry, the pressure is 4 kg / cm 2 , the weft blowing pressure in the air jet loom is 1 ~ 2 kg / cm 2 , the starting pressure of the medium and large diesel engine is 25 ~ 60 kg / cm 2 , oil well fracturing, pressure 150 kg / cm 2 , "secondary method" oil production, pressure is about 50 kg / cm 2 , high pressure blasting coal pressure is about 800 kg / cm 2 , the defense industry The pressure in the compressed air is the power. Submarine ups and downs, torpedo shooting and driving, and wreck salvage, etc., are powered by different pressures of compressed air.

2. Compressed gas for refrigeration and gas separation:

The gas is liquefied by compression, cooling, expansion, and is used for manual refrigeration such as ammonia or Freon compressors. The compression pressure is usually 8 to 12 kg/cm 2 , and this type of compressor is usually a "refrigerator" or "ice machine". Further, in the case where the liquefied gas is a mixed gas, the components may be separately separated in a separating apparatus to obtain various gases which are acceptable for lip reading. Such as pure oxygen, pure nitrogen, and pure rare gases such as helium, neon, argon, and xenon, which can be obtained after air liquefaction separation.

3. Compressed gas for synthesis and polymerization:

In the chemical industry, gas is compressed to high pressure, which is often advantageous for synthesis and polymerization. For example, nitrogen and hydrogen are used to synthesize ammonia, hydrogen and carbon dioxide to synthesize methanol, carbon dioxide and ammonia to synthesize urea. In the chemical industry, for example, high pressure polyethylene has a pressure of 1,500 to 3,200 kg/cm.

4. It is difficult to compress the gas with regard to the hydrorefining of the oil:

In the petroleum industry, hydrogen is heated by artificial means, and reacted with oil after pressurization, so that the recombination of hydrocarbons can be cracked into light components of hydrocarbons, such as lightening of heavy oil, hydrorefining of lubricating oil, and the like.

5, gas delivery:

Compressors used to pipe gases, depending on the length of the pipe, determine its pressure. When sending remote gas, the pressure can reach 30 kg/cm2. The chlorine gas bottling pressure is 10 to 15 kg/cm 2 and the carbon dioxide bottling pressure is 50 to 60 kg/cm 2 .
