Effect of Water Temperature on Performance of Liquid Ring Vacuum Pump

Today, I would like to share with you the effect of water temperature on the performance of liquid ring vacuum pumps. Many people may not have heard much about it and know little about it. So let's talk to Xiaobian to get more knowledge.

The absolute pressure in the pump chamber of liquid ring vacuum pump is the sum of gas partial pressure and saturated vapor pressure. Assuming that the relative humidity in the pump chamber is 100%, the higher the water temperature, the higher the saturated vapor pressure and the higher the absolute pressure in the corresponding pump chamber, the lower the vacuum pumped by the pump. That's why high water temperatures reduce vacuum. The limit vacuum degree of the liquid ring vacuum pump is basically equal to the saturated vapor pressure of the corresponding water temperature.
