What is the purpose of a small air compressor

The uses of small air compressors are as follows:

　　1, compressed air as power:

Drive all kinds of pneumatic machinery. The exhaust pressure of pneumatic tools is 7-8 kg/cm². It is used to control instruments and automation devices. The pressure is about 6 kg/cm². The vehicle automatically opens and closes doors and windows. The pressure is 2～ 4 kg/cm2, mixing in the pharmaceutical industry and wine industry. The ups and downs of submarines, the shooting and driving of torpedoes, and the salvage of sunken ships are all powered by compressed air under different pressures.

　　2, compressed gas is used for refrigeration and gas separation:

　　 The gas is compressed, cooled, expanded and liquefied, and is used for artificial refrigeration (refrigeration and air conditioning, etc.) such as ammonia or freon compressors. The compression pressure is mostly 8-12 kg/cm², and this type of compressor is usually called a "refrigerator" or "ice machine". In addition, if the liquefied gas is a mixed gas, the components can be separated separately in the separation device to obtain qualified lip-reading gases. For example, pure oxygen, pure nitrogen, and pure xenon, krypton, argon, helium and other rare gases can be obtained after air liquefaction and separation.

　　3, compressed gas is used for synthesis and polymerization:

　　In the chemical industry, gas is compressed to high pressure, which is often advantageous for synthesis and polymerization. For example, the synthesis of ammonia from nitrogen and hydrogen, the synthesis of methanol from hydrogen and carbon dioxide, and the synthesis of urea from carbon dioxide and ammonia. In the chemical industry, for example, the pressure of high-pressure polyethylene can reach 1500-3200 kg/cm².

　　4, gas delivery:

　　 (1) The pressure of the compressor used for pipeline transportation of gas depends on the length of the pipeline. When sending remote gas, the pressure can reach 30 kg/cm². The chlorine bottling pressure is 10-15 kg/cm², and the carbon dioxide bottling pressure is 50-60 kg/cm².

　　 (2) In the chemical industry, gas is compressed to high pressure, which is often advantageous for synthesis and polymerization. For example, the synthesis of ammonia from nitrogen and hydrogen, the synthesis of methanol from hydrogen and carbon dioxide, and the synthesis of urea from carbon dioxide and ammonia. In the chemical industry, for example, the pressure of high-pressure polyethylene can reach 1500-3200 kg/cm².
