Principle of screw compressor
lubricating ：Due to the lubricating effect of the lubricating oil, the female screw can be directly driven by the male screw, which can reduce the pair of synchronous gears compared with the oil-free screw, simplifying the main structure and reducing the cost.
seal ：Due to the structural limitation of the screw compressor, there must be a certain gap between the screw rotor and the casing. The oil film formed by the lubricating oil can seal the air, reduce the gas leakage between the rotor and the casing, and improve the compression efficiency.
clean ：The lubricating oil can take away impurities in the compressed air during the compression process and reduce the wear on the rotor.
Anti-oxidation, anti-corrosion
cool down
