Screw air compressor main components and principles

Screw air compressor is a screw compressor , motor , oil separators , coolers , fans, water separator, electrical control box and trachea Road , oil pipeline , regulating system components. Compressor casing body has a pair of precision machined teeth together in mutual yin and yang of the rotor . For Direct unit, direct drive motor through flexible coupling male rotor , the gear unit, the motor drive shaft through a flexible coupling gear , rotating through the gear to Yoko . Injected into oil mixed with air in the rotor slot after the effective compression , the oil forms a film between the rotor slots , avoid direct contact with metal sealing gap between the rotor and the ministries and absorb most of the heat of compression . Unit without pump, relying on oil and gas separator gas through hydraulic pressure to the lubrication points . Oil , gas mixture discharged from the compressor through the oil separator, cyclone separation method of most oils , residual oil through the oil separator filter for further settled in the bottom of the fine separation filter. Use of pressure filter at the bottom of the oil return pipe into the compressor , the oil level gauge mounted on the oil separator, minimum pressure valve and safety valve . Oil separator tank and also doubles as a gas tank .
