The screw air compressor is divided into two screw air compressor and single screw air compressor

The type and principle of air compressor, air compressor (aircompressor: English) is the main body of the gas source device. It is a device that converts the mechanical energy of the prime motor (usually motor) to the gas pressure energy, and is the pressure generating device of the compressed air.
The types and principle, many different types of air compressors, according to the working principle can be divided into the compressor, compressor speed, volume of the compressor working principle is the volume of compressed gas, the gas molecules in the unit volume density increased to increase the pressure of compressed air; working principle of speed compressor is to improve the speed of gas molecules the kinetic energy to make the gas molecules has transformed into gas pressure energy, thereby increasing the pressure of compressed air.
Commonly used air compressors are piston air compressors, screw air compressors, and screw air compressors. They are divided into two screw air compressors and single screw air compressors, centrifugal compressors and sliding vane air compressors, and scroll air compressors. (below) is the definition of all kinds of compressors. The compressors such as cam, diaphragm and diffuser are not included, because they are relatively small in size and special in use.
