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, the vehicle automatically, doors and windows open and close, a pressure of 2 to 4 kg / cm, the pharmaceutical industry, the wine industry stirring, pressure of 4 kg / cm, air jet loom weft blowing pressure of 1 to 2 kg / cm, medium and large Diesel starting pressure of 25 to 60 kg / cm screw compressor brand, the well fracturing pressure of 150 kg / cm, "second law" brand air compressor oil, a pressure of about 50 kg / cm high pressure blasting mining pressure of about 800 kg / cm air compressor brand supply, 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, the gas is 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. The chemical industry, such as high pressure polyethylene pressure of 1500 to 3200 kg / cm. Compression principle (1) the process of breathing: the motor drives the rotor, Lord, from the red rotor groove space go to the inlet opening in the end wall, the space, the outside air is filled wherein, when the intake side turned away from the end face of the rotor the air intake when the air between the tooth groove is closed in the main, from between the rotor and the casing, complete shell of the intake process. (2) compression process: at the end of inspiration, Lord, enclosed volume peak from the rotor teeth and the casing is formed with the change of angle of the rotor is reduced, according to a spiral movement, this is "the compression process." (3) and the compressed gas injection process: during transfer, decreasing the volume of the gas continue to be compressed, the pressure increase, the temperature increases, at the same time, due to the pressure difference becomes mist lubrication is injected into the compression chamber, whereby achieve compression and reduce the discharge temperature of the seal lubrication effect. (4) Exhaust process: when the tooth peak enclosed rotor is rotated to meet with the cabinet exhaust port, the compressed air begins to discharge until the tooth peaks coincide with the tooth surface grooves moved exhaust face, this time tooth groove space zero discharge process is complete. At the same time, the main rotor from the other tooth ditch has been rotated to the inlet end of the oil-free compressor brand, the formation of the largest space to begin the process of breathing, which began a new compression cycle.
