Background technique

Air compressor is the basic product of industrial modernization. It is often said that electrical and automation have the meaning of full pneumatic; and air compressor is to provide air source power, which is the main body of the electromechanical air source device, which is the core equipment of the pneumatic system. It is a device that converts the mechanical energy of the prime mover (usually an electric motor) into gas pressure energy, and is a gas pressure generating device for compressed air. There are many types of air compressors, which can be divided into volumetric compressors and speed compressors according to the working principle. The working principle of the positive displacement compressor is to compress the volume of the gas, so that the density of the gas molecules in the unit volume increases to improve the compressed air. Pressure; The working principle of the speed compressor is to increase the movement speed of gas molecules, so that the kinetic energy of gas molecules can be converted into the pressure energy of the gas, thereby increasing the pressure of compressed air. Now commonly used air compressors include piston air compressors, screw air compressors (screw air compressors are divided into twin-screw air compressors and single-screw air compressors); centrifugal compressors and sliding vane compressors. Air compressors; scroll air compressors, etc.

Take the screw piston supercharger as an example. It is a rotary volumetric compressor, in which two rotors with helical gears mesh with each other, so that the volume of the two rotors meshes from large to small, thereby compressing and discharging the gas. The supercharger capable of boosting to 4.0 MPa level in the prior art is mainly boosted by combining an oil injection screw rod and an oil dripping piston machine. This structure has the following disadvantages in actual use: the oil content in the air is high, polluting the environment, and the oil and gas must be separated by an oil-gas separator after the first-stage compression, which increases the pressure loss of the gas circuit.
