Air compressor 
 Air compressor air compressor screw air compressor piston air compressor 
 Air compressor is the main gas supply, it is the prime mover (usually motor) and mechanical energy can be converted into gas pressure device, is the air pressure generating device 
 Many different types of air compressors, according to the principle can be divided into positive displacement compressors, reciprocating compressors, centrifugal compressors, positive displacement compressor is the volume of gas is compressed, so that the gas molecules per unit volume density to increase the pressure of compressed air; centrifugal compressor works to increase the velocity of gas molecules, so that gas molecules have the kinetic energy into pressure energy of the gas, thereby increasing the pressure of compressed air. Reciprocating compressors (also known as piston compressor) works directly compressed gas, when the gas reaches a certain pressure after discharge. 
 There are now commonly used in air compressor piston air compressor, screw air compressors (screw air compressor is divided into twin-screw and single screw air compressor air compressor), centrifugal compressors and sliding chip-type air compressors, scroll air compressor. 
 Air compressor features 
 Directly driven by the compressor motor, the crankshaft rotation, so that the piston rod driven by reciprocating motion produced, causing the cylinder volume change. As the cylinder pressure change, the air through the intake valve through the air filter (muffler) into the cylinder, the compression stroke, due to the reduced volume of the cylinder, the role of compressed air through the exhaust valve, the exhaust pipe, one-way valve (check valve) into the gas tank, when the pressure of 0.7MPa rated discharge pressure by the pressure switch control and automatic shutdown. When the tank pressure down to 0.5 - 0.6MPa pressure switch automatically when the connection starts.
