Screw compressor has two twin-screw and single screw. Single screw compressor screw air compressor invention than ten years later, the twin-screw compressor design more reasonable, advanced. Twin-screw air compressor to overcome the single screw compressor imbalance disadvantage bearing fragile; a long life large screw air compressor, screw air compressor manufacturers low noise, more energy saving. In the 1980s the technology is mature, widening its scope of application. Screw Compressors Symptom: The fan motor overload distortion fan; fan motor failure; fan motor thermal relay fault (aging); loose wiring; cooler blockage; large exhaust resistance. Screw Compressors Symptom: Unit current large voltage is too low; loose wiring; unit pressure exceeds the rated pressure; oil separator core blockage; contactor fault; host failure; Main motor failure screw compressor is a working volume rotary movement The volume of gas compression machinery. Depend on the volume of the compressed gas changes to achieve, and the volume change is by means of a compressor of a rotary movement of the rotor within the housing to achieve. Screw compressor basic structure: In the body of the compressor screw air compressor, arranged in parallel to a pair of spiral intermeshing rotors, usually outside of the pitch circle of the rotor has teeth, called the male rotor or male thread . The inner circle of the rotor section having a concave tooth sell screw air compressor, known as the female rotor or female screw, usually male rotor is connected with the prime mover, driven by the male rotor female rotor rotating rotor bearing on the final realization of axial positioning and bear the compressor axial force. Both ends of the rotor cylindrical roller bearings radial position of the rotor to achieve and sustain a compressor radial force. At both ends of the compressor body, respectively, to open a certain shape and size of the orifice. One for sucking, called intake port; and the other for the exhaust, referred to as an exhaust port.
