Air compressor

Air compressor
1. Air compressor is the main body of the air source device. It is the device that converts the mechanical energy of the prime mover into gas pressure energy and is the pressure generating device of compressed air.
2. There are many kinds of air compressors, which can be divided into volumetric compressors, centrifugal compressors, and piston compressors according to the working principle.
1) The working principle of a positive displacement compressor is to compress the volume of gas so that the density of gas molecules in unit volume increases to improve the pressure of compressed air;
2) The working principle of a centrifugal compressor is to improve the movement speed of the gas molecules so that the kinetic energy of the gas molecules is converted into the pressure energy of the gas, so as to improve the pressure of the compressed air.
3) The working principle of the piston compressor is to directly compress the gas, and when the gas reaches a certain pressure, it is discharged.
3, now commonly used air compressors are piston air compressor, screw air compressor, centrifugal compressor, and slide vane air compressor, scroll air compressor.
Relevant people said that the choice of air compressor is mainly based on the working pressure and flow of the pneumatic system. The working pressure of the gas source should be about 20% higher than the maximum working pressure in the pneumatic system because the loss along the gas supply pipeline and local loss should be considered. If the operating pressure in some parts of the system is low, a pressure-reducing valve can be used to supply air. The rated exhaust pressure of the air compressor is divided into low pressure (0.7~1.0MPa), medium pressure (1.0~10MPa), high pressure (10~100MPa), and super high pressure (over 100MPa). The rated exhaust pressure of the air compressor can be selected according to actual requirements. The common pressure is generally 0.7~1.25MPa.
