Cavitation Erosion Principle and Prevention of Water Ring Vacuum Pump Casting

Jan 16, 2018

In the process of pump casting,there are many processes need attention. Cavitation is caused by liquid gasification, liquid molecules escaping liquid, into gas molecules inside, called "gasification." Liquid gasification level and the size of the pressure, the degree of heat has nothing to do. Gas dissolved in the liquid, the pressure and heat changes will also be released into the formation of cavitation.

Water ring vacuum pump cavitation scene purifying steps and prevention:

(1)increase the heat of water

(2)popularization and selection of the correctness of the vacuum pump to run in the insurance area

(3)Device cavitation shield tube

(4)Equipped with air jets

(5)Use lower saturated steam liquid as working fluid
