Oil-injected air compressor
Screw compressor is composed of a pair of parallel, meshing female and male screws, which is one of the most widely used rotary compressors. Divided into single screw and twin-screw two, usually said that the screw compressor refers to the twin-screw compressor.
Screw compressor compression principle:
Suction process: when the rotor rotates, the volume between the teeth formed by the main and auxiliary rotors gradually expands, which is only connected with the suction port, and the outside air is sucked into the volume between the teeth. When the volume between teeth increases to a large value, the volume between teeth is disconnected from the suction port, and the suction ends. This is the "intake process".
Sealing and conveying process: at the end of suction, the teeth of the main and auxiliary rotors are sealed with the casing, and the air in the volume between the teeth is sealed in the closed cavity composed of the main and auxiliary rotors and the casing, which is called "sealing process". When the two rotors continue to rotate, the teeth of the main and auxiliary rotors mesh with each other, the meshing surface gradually moves to the exhaust end, and the air in the volume between the teeth is also transported to the exhaust end, which is the "conveying process".
Compression and fuel injection process: in the conveying process, with the rotation of the rotor, the volume between the teeth decreases due to the meshing of the rotor teeth, and the gas volume in the volume between the teeth also decreases, the gas is compressed, and the pressure increases, which is called "compression process". At the same time of compression, lubricating oil is sprayed into the groove due to pressure difference and mixed with air.
