There are many kinds of air compression pumps, which can be divided into positive displacement compression pumps and speed compression pumps according to their working principles. The working principle of positive displacement compression pump is to compress the volume of gas, so as to increase the density of gas molecules in unit volume and increase the pressure of compressed air. The working principle of speed compression pump is to improve the moving speed of gas molecules, so that the kinetic energy of gas molecules can be converted into pressure energy of gas, thus increasing the pressure of compressed air.
