Liquid ring vacuum pump is by relying on the impeller rotary motion in the pump chamber to periodically change the working chamber volume in order to achieve vacuum pump, which works, making the liquid ring vacuum pump in the selection Need to pay attention to the problem compared to other vacuum pumps is even more complex, then we will bring liquid ring vacuum pump selection considerations. Liquid ring vacuum pump selection notes 1, the type of liquid ring vacuum pump to determine the type of liquid ring vacuum pump mainly by pumping medium, the amount of work required, vacuum or exhaust pressure may be. 2, as far as possible in the high efficiency area, that is, critical vacuum or critical exhaust pressure in the region. 3, according to the amount of exhaust system required to select the right vacuum pump, initially selected the type of pump, the vacuum pump, but also according to the amount of gas required to system selection of pump models. About pumping speed selection and pumping time calculation can refer to: vacuum calculation formula. 4, should be avoided in the maximum vacuum or maximum exhaust pressure near the operation. Operating in this area is not only inefficient but also unstable and prone to vibration and noise. Cavitation occurs frequently in vacuum applications where the vacuum is high, and the obvious hallmark of this phenomenon is noise and vibration in the pump. Cavitation can cause damage to the pump body, impeller and other parts, so that the pump can not work. Each product because of the different working environment and ability to work, so in the selection of the focus may need to be different, from the above analysis, we can find that the liquid ring vacuum pump, it not only pay attention to the product type, at the same time Also ensure that the parameters meet the needs of work.
