Connecting a centrifugal impeller in series ahead of the vortex impeller in a centrifugal vortex pump can improve the cavitation performance of that pump
Thread Content
I would like to ask the experts for their analysis on how to improve cavitation in the centrifugal impellers of such pumps
1. Use materials resistant to cavitation. 2. Improve the conditions at the inlet. 3. Increase the inlet pressure, etc
Avoid bag-shaped shapes with the character “ji” at the inlet to reduce cavitation. The inlet pipe of the pump should not be smaller in size than the pump’s own inlet. Regularly clean the pump’s inlet filter.
