High Pressure Air Compressors

The gas compression of Screw Air compressor is achieved by the volume change of the cogging of the male and female rotors installed in the casing and meshed with each other in parallel. The rotor pair rotates in the casing which is precisely matched with it, so that the gas between the rotor slots continuously produces periodic volume changes, and pushes from the suction side to the discharge side along the rotor axis to complete the three working processes of suction, compression and exhaust. In the process of air intake, when the rotor rotates, the tooth groove space of the male and female rotor is transferred to the opening of the air inlet end wall. At this time, the tooth groove space of the rotor is connected with the air inlet. Because the gas in the tooth groove is completely discharged during exhaust, the tooth groove is in a vacuum state when exhaust is completed. When it is transferred to the air inlet, the external gas is sucked in and enters the tooth groove of the male and female rotor along the axial direction. When the gas fills the whole tooth groove, the end face on the inlet side of the rotor rotates away from the air inlet of the casing, and the gas in the tooth groove is closed. During the compression process, when the suction of the male and female rotors ends, the tooth tips of the male and female rotors will be closed with the casing, and the gas will no longer flow out in the tooth groove. The meshing surface gradually moves to the exhaust end. The groove space between the meshing surface and the exhaust port gradually decreases, and the gas in the groove is compressed and the pressure increases. During the exhaust process, when the meshing end face of the rotor turns to be connected with the exhaust port of the casing, the compressed gas begins to be discharged until the meshing surface of the tooth tip and the tooth groove moves to the exhaust end face. At this time, the space between the meshing surface of the male and female rotor and the tooth groove of the exhaust port of the casing is zero, that is, the exhaust process is completed. At the same time, the length of the tooth groove between the meshing surface of the rotor and the air inlet of the casing reaches, The intake process proceeds again.
