Working Principle of Liquid Ring Vacuum Pump

The liquid ring vacuum pump (hereinafter referred to as the liquid ring pump) is a kind of coarse vacuum pump. The maximum vacuum it can obtain is 2000-4000Pa, and the series air ejector can reach 270-670Pa. Water-ring pump can also be used as compressor, called water-ring compressor. It belongs to low-pressure compressor, and its pressure range is 1-2*105Pa gauge pressure.

Water ring pumps were initially used as self-suction pumps, and then gradually used in petroleum, chemical industry, machinery, mining, light industry, medicine and food and many other industrial sectors. In many industrial processes, such as vacuum filtration, vacuum water diversion, vacuum feeding, vacuum evaporation, vacuum concentration, vacuum moisture regain and vacuum degassing, water ring pumps are widely used. Due to the rapid development of vacuum application technology, the water ring pump has been attached great importance in obtaining rough vacuum. Because the gas compression in the water ring pump is isothermal, it can extract flammable and explosive gases, in addition, it can also extract dust and water containing gases. Therefore, the application of the water ring pump is increasing.

The working fluid of water-ring vacuum pump can also use other suitable liquids. Whichever working fluid is used, it is collectively called liquid-ring vacuum pump. Water ring vacuum pump is one of the most common and widely used liquid ring vacuum pumps.
