water ring vacuum pump structure and principle

Water ring vacuum pump (referred to as water ring pump) is a kind of crude vacuum pump. The ultimate pressure water ring pump it can obtain is in many processes of petroleum, chemical industry, machinery, mining, light industry, papermaking, power, metallurgy, medicine, food and municipal and agricultural sectors, such as vacuum filtration, vacuum feeding, vacuum degassing, vacuum evaporation, vacuum concentration and vacuum return, It has been widely used. Because the process of compressed gas in water ring pump is isothermal, it can pump out inflammable and explosive gas, as well as the gas containing dust and water. Therefore, the application of water ring pump is increasing day by day.

Water ring pump is composed of impeller, pump body, suction and exhaust disc, water ring formed by water on the inner wall of pump body, suction port, exhaust port, auxiliary exhaust valve, etc.

In the water ring pump, the auxiliary exhaust valve is a special structure. Generally, rubber ball valve is used. Its function is to eliminate the phenomenon of over compression and insufficient compression during the operation of the pump. Both of these phenomena will cause excessive power consumption. Because the water ring pump has no direct exhaust valve, and the exhaust pressure is always fixed, the compression ratio of the water ring pump depends on the end position of the air inlet and the start position of the exhaust port, but these two positions are fixed, so they are not suitable for the needs of the change of the suction pressure. In order to solve this problem, rubber ball valve is generally set under the exhaust port, so that when the pump cavity reaches the exhaust pressure too early, the ball valve will automatically open and the gas will be discharged, eliminating the phenomenon of over compression. Generally, in the design of water ring pump, the minimum suction pressure is used to determine the compression ratio, so as to determine the starting position of the exhaust port, so as to solve the problem of insufficient compression.
