Vacuum booster pump working principle and maintenance matters

Vacuum booster pump is mainly used for drawing light vacuum booster brake system can also be used for other transport vehicles and construction machinery. The use of vacuum assisted braking system can improve brake reliability and reduce driver fatigue, help to reduce the incidence of traffic accidents and improve vehicle safety. At present, the rapid development of domestic light vehicles, which undoubtedly for the vacuum booster pump provides a vast market. Therefore, in the promotion and use of the process, we must understand and master its performance, principles. The only way to effectively ensure the pump braking performance, extend the service life, play a safety role.
1, vacuum booster pump working principle

The vacuum booster pump is mainly composed of the pump body, rotor, slider, pump cover, gear, seal and other components. When the pump is working, the eccentric rotor with four slides rotates counterclockwise and the slider rotates in its own centrifugal force Under the action, close to the inner wall of the pump glide, suction studio continues to expand, was pumping gas through the suction tube to open the one-way valve (pump built-in check valve, the system from the packing effect) into the suction studio. When the slider to a certain position, the inhalation is completed, then inhaled gas is isolated, the rotor continues to rotate, the isolated gas is gradually compressed - the pressure rise. When the studio goes to communicate with the vent, the gas is vented from the vent. Pump work process, the slider will always be divided into four pump chamber, the rotor per revolution, there are four suction and exhaust process.

2, the use and maintenance considerations Vacuum booster pump is a high precision, more sensitive to the work of the pump, the use of the following rules must be strictly followed:

(L) The vacuum booster pump uses oil to lubricate the friction surfaces and seals all clearances (rotor, slider, pump body and pump cover). Therefore, appropriate lubricant and suitable lubrication method must be selected.

(2) should be used regularly check the operation and lubrication is normal, with or without abnormal noise, so that timely detection and troubleshooting.

(3) should always check the use of the pump leaks.

(4) If you do not use the vacuum booster pump for a long time, do not immediately work full load when reused
