Liquid ring vacuum pump cavitation
Thread Content
The vacuum pump in the device broke yesterday. The vacuum pump is water-sealed and the negative pressure is around -0.03. After opening the pump body, it was found that the impeller was severely cavitated and most of the blades had been broken. I would like to ask everyone, what causes such serious cavitation.
No corrosion? If there is no corrosion, it is usually caused by the high temperature of the string water. Also, don’t ignore the issue of material
Yes, there is corrosion, and I personally think there is something wrong with the material. 2#yanan0930
I think it is possible that the temperature at your inlet is too high or there is a problem with the cooler of the water ring pump. The medium has a phase change, so cavitation occurs!
