Compression principle (1) the process of breathing: the motor drives the rotor, Lord, when the rotor is in the red groove space go from the inlet end wall opening, the space is large well-known compressor manufacturers, the outside air is filled wherein, when the rotor into When the gas-side end face turned away from the shell of the inlet, the air between the tooth groove is closed in the main, from between the rotor and the casing, complete the process of breathing. (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 compressor manufacturers start of discharge until the tooth peaks coincide with the tooth surface grooves moved exhaust face, In this case tooth groove space zero discharge process is complete. At the same time large air compressor manufacturers, the main rotor from the other tooth ditch has been rotated to the intake side, forming the largest space Cottle compressor manufacturers, began the process of breathing, which began a new compression cycle. The main fault 1, piston oil-free air compressor piston rings and packing devices are aircraft without greasing. Under normal circumstances, after essentially pure compressed gas free of oil, but because of the oil scraper ring often scraping the oil is not complete, sealed well, often resulting in oil filler device even went on the piston ring, so that the compressed gas oil. In addition, the exhaust temperature is high, sometimes up to 200 ℃; cooler clogged, so that the cooling effect is not good; piston ring touches the oil, are particularly vulnerable to wear and tear; beat leak valve; cylinder liner wear. 2, screw-type air compressor screw air compressor malfunction little, as long as regular maintenance of oil separator, air and oil filters, etc., will be able to ensure their normal operation.
