1. Classification of Air Compressor The air compressor is the main body of the air source device. It is a device that converts the mechanical energy of the prime mover (usually an electric motor) into gas pressure energy, and is a pneumatic 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 volumetric compressor is to compress the volume of gas, so that the density of gas molecules per unit volume is increased to increase the pressure of compressed air. The working principle of the speed compressor is to increase the velocity of gas molecules and the kinetic energy of gas molecules. It is converted into the pressure energy of the gas, thereby increasing the pressure of the compressed air.

2. Working principle of piston air compressor In the pneumatic transmission, a positive displacement piston type air compressor is usually used. Here are two typical structures to help understand how air compressors work. Figure 3.33 (animated) and Figure 3.34 (animated) give the working principle of the vertical and horizontal air compressors. The center line of the cylinder of the vertical air compressor is perpendicular to the ground, and the center line of the cylinder of the horizontal air compressor is parallel to the ground. The rotary motion of the prime mover (motor or internal combustion engine) is converted into a reciprocating linear motion of the piston via the crank-link mechanism. The process of intake and exhaust in the air compressor is similar to the process of oil absorption and oil pressure of the hydraulic pump, and will not be described here.
3. Selection of Air Compressor 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 highest working pressure in the pneumatic system, because the loss and local loss of the gas supply pipeline should be considered. If the working pressure requirements are low in some parts of the system, 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 ultra high pressure (100MPa or more), which can be selected according to actual needs.
