中英文翻译 The screw air compressor Screw air compressor is the injection of single stage double screw compressor, divided into single screw air compressor and screw air compressor, efficient use of belt drive, drive the host rotation of compressed air, through the oil for cooling the compressed air in the host, the host of air and oil discharge of the mixed gas after coarse, fine two channel separation, the compressed oil separated out in the air, finally get the clean compressed air. Cooler for cooling the compressed air and oil. With reliable performance, small vibration, low noise, convenient operation, few wearing parts, high efficiency is the biggest advantage of. Screw compressor is a new type compressor, air is compressed alveolar ridge volume change installed on the casing are mutually parallel rotor meshing and achieve. The rotor side in the case and it with precision internal rotation so that gas rotor slot between continuously cyclical changes in volume and along the rotor axis, by the suction side to the discharge side suction, compression, exhaust, complete three working process. Twin screw compressor is a double volume type rotary compressor, which is the main (Yang) side (Yin) with two rotor, composed of meshing pair, vice principal of rotor profile of external components of the element volume closed with the inner wall of the casing, shortage of twin screw is 40 cubic meters and above machine type to add gear, increase power consumption and prone to head lock; while the worm compressor is a uniaxial volume type rotary compressor, the meshing pair is composed of a worm wheel and two symmetrical layout, wall by the worm screw groove and the star wheel tooth surface and the casing form element volume closed, but the problem is the Star blade material has yet to be improved. The main performance parameters of screw type air compressor power, volume flow rate, pressure, exit temperature, discharge pressure and speed etc.. And in the design of screw air
