Why add atmospheric ejector to vacuum pump?

Addtime: 2020-07-16 Browse times: 2529

The problems of high noise and impeller cavitation often occur in the operation of water ring vacuum pump. It is generally believed that the reason is that the inlet pressure of vacuum pump is too low, resulting in bubble rupture, and in serious cases, the rotor of vacuum pump will be broken and scrapped; when the capacity of vacuum pump is too large, the above problems are especially serious. The practice shows that this problem can be effectively solved by adding atmospheric ejector to vacuum pump.


The functions of atmospheric ejector are as follows:


First, expand the working range of vacuum pump to prevent cavitation;


The second is to increase the suction capacity of vacuum pump. The practice of a unit shows that the noise of the vacuum pump is significantly reduced and the vacuum of the unit is less affected by the installation of atmospheric ejector. The overall performance of the vacuum pump is better when the ambient temperature is lower in winter.
