Why does the air booster pump need to be driven with clean air at 2-8 bar
Why does the air booster pump require clean air with a driving pressure range of 2-8 bar? Below, the editor will take you to learn more.
According to theory, the drive can be driven from 0-8 bar, but it involves the sensitivity of the directional valve, and the friction between the sealing rings causes the driving air pressure to be between 1.5-2 bar to push the directional valve to work. Therefore, the lower driving pressure of the air booster pump is set at 2 bar by Feentor. Why is the upper line pressure set at 8 bar? This is also determined based on the material of the directional valve. The material shell of the directional valve is generally aluminum alloy, which facilitates the diffusion of high temperatures caused by frequent friction between the valve core and valve cover. Because the material is aluminum alloy, it has better impact resistance than other metals. Therefore, it is recommended to drive the air pressure below 8 bar. The higher the air pressure, the faster the valve core runs, and the greater the impact force. Why do we need clean compressed air? Because the directional valve is sealed by a sealing ring, inhaling unclean compressed air for a long time can cause impurities to settle, leading to increased wear on the sealing ring and affecting the service life of the booster pump.
