The role of the air compressor in specific applications in various industries? Air compressors are widely used in electric power, textile, steel, food, pharmaceutical, breathing, diving, fire, electronics, machinery, equipment, automotive, packaging, printing, toys, chemicals , energy, glass, green, metal, PET blow molding, shipbuilding, military and other aspects. 1, compressed air as a power: total drive various pneumatic machinery, pneumatic tools discharge pressure of 7 to 8 kg / cm, instrumentation and automation equipment for controlling pressure of about 6 kg / cm, automatic vehicle empty press brand faucet, doors and windows open and close, a pressure of 2 to 4 kg / cm, the pharmaceutical industry, wine industry stirring, pressure of 4 kg / cm, air jet loom weft blowing pressure of 1 to 2 kg / cm, medium and large diesel engine starting pressure of 25 to 60 kg / cm, well fracturing pressure of 150 kg / cm, "second law" oil pressure of about 50 kg / cm, high pressure blasting mining coal pressure of about 800 kg / cm, the pressure in the air defense industry for its power. The ups and downs submarine, torpedo firing and driving and wreck salvage, etc., all with different pressure compressed air for power. 2, the compressed gas used for refrigeration and gas separation: gas compressed, cooled, liquefied and expanded for artificial cooling, such as ammonia or freon compressor. More compression pressure of 8 to 12 kg / cm, this type of compressor is usually a "refrigerator" or "ice." Also in the case of gases liquefied gas mixture, it can be in the separation apparatus, the components are separated out, get qualified lip reading to a variety of gases. As after air separation can be pure oxygen, nitrogen, and pure xenon, krypton, argon, helium and other rare gases. 3, the compressed gas used in the synthesis and polymerization: In the chemical industry brand air compressor supply, gas compressed to high pressure, often advantageous synthesis and polymerization. Such as ammonia, nitrogen and hydrogen, hydrogen and carbon dioxide synthesis of methanol, carbon dioxide and ammonia synthesis urea. Chemical industry piston air compressor brands, such as high pressure polyethylene pressure of 1500 to 3200 kg / cm. Reciprocating piston compressor works Reciprocating piston compressor is generally driven by the electric motor through V-belt axis, and then the rod driven piston reciprocating motion, so that the valve, piston, cylinder piston cavity volume consisting of changes reach r of the compressed air. Compressed air is compressed in the cold again, and finally into the gas tank. Mainly by the gas tank cylinder, pressure gauge, safety valve and other components, pressure can stabilize the air line pressure to reduce fluctuations caused by the compressor. If for some reason it inside the air than the rated pressure, the safety valve will automatically open, the compressed air is discharged into the air compressor brands to ensure safe operation. I use the plant's Fujian Compressor Plant production V-0.3 / 10-type and W-0.6 / 10 air compressor safety valve opening pressure rated discharge pressure of 1.05 to 1. 08 times. Of course, different specifications of the air compressor, safety valve opening pressure is not the same.
