What is the difference between an air pump and an air compressor?


The basic principle is the same. The only difference is that the structure is not the same. The intake and exhaust of the air compressor have valves, and the exhaust of the air pump is generally straight.

It is better to use an air compressor.

There are many types of air compressors, which can be divided into positive displacement compressors, speed compressors, and positive displacement compressors according to their working principles. Pressure; The working principle of the speed compressor is to increase 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, thereby increasing the pressure of the compressed air.


Air compressor and air pump are two names for the same type of machine. The principle is the same, and the structure is similar. The main differences are:

1. The distinction between names: Small air compressors are called air pumps, and air compressors used in vehicle pneumatic braking systems are generally called air pumps.

2. There are different levels of pressure provided. In addition, there are valves for the intake and exhaust of the air compressor, and the exhaust of the air pump is generally straight.
