Screw compressor is a kind of working volume for rotary movement of positive displacement type gas compression machinery is divided into Belt Driven Screw Air Compressor, Oil-free Screw Air Compressor and so on. The compression of the gas depends on the change of volume to realize, and the change of volume and with the help of a pair of compressor rotor in the casing for rotary movement to achieve.
In the compressor body, parallel to the configuration of a pair of intermeshing spiral rotor, usually outside the pitch circle with a convex tooth rotor, known as the sun rotor or sun screw. The pitch circle with concave teeth within the rotor, known as the yin rotor or yin screw, generally the yang rotor and the prime mover connection, driven by the yang rotor yin rotor rotation rotor on the last pair of bearings to achieve axial positioning, and to withstand the axial force in the compressor. Cylindrical roller bearings at both ends of the rotor to achieve radial positioning of the rotor, and bear the radial force in the compressor. At both ends of the compressor body, respectively, open a certain shape and size of the orifice. One for suction, known as the inlet; the other for exhaust, known as the exhaust port.
Rotor rotation, yin and yang rotor teeth groove space in the turn to the inlet end wall opening, its space is the largest, at this time, the rotor teeth groove space and the inlet of the communication, because in the exhaust of the teeth groove of the gas is completely discharged, the exhaust is completed, the teeth groove is in a vacuum state, when the turn to the air inlet, the outside world that is sucked in the gas, along the axial direction into the teeth groove of the yin and yang rotor. When the gas fills the whole tooth groove, the rotor inlet side end face turns away from the casing inlet, the gas in the tooth groove is closed. Yin Yang rotor in the end of suction, the tip of its Yin Yang rotor teeth will be closed with the casing, at this time the gas in the tooth groove is no longer outflow. Its engagement surface gradually moves towards the exhaust end. The space of the tooth groove between the meshing surface and the exhaust port is gradually small, and the gas in the tooth groove is compressed to increase the pressure. When the rotor's meshing surface to the exhaust port with the case, the compressed gas began to discharge, until the tooth tip and the tooth groove of the meshing surface to the exhaust surface, at this time the yin and yang rotor's meshing surface and the case of the exhaust port of the tooth groove space is 0, that is, to complete the exhaust process, at the same time, the rotor's meshing surface and the case of the air inlet between the tooth groove between the length of the longest, and then the process of intake and then carry on.
