When the pump is subject to cavitation, the inlet and outlet pressures change
Thread Content
Why does the outlet pressure decrease when the pump is cavitating? If the outlet pressure decreases, then the inlet vacuum level should increase, right? Should I choose 1 for this question?
The vacuum level decreases, and the pressure gauge shows a drop
The vacuum level is high and the negative pressure is low; the original poster has it backwards.
I found this statement online: during cavitation, the vacuum level indicated by the vacuum gauge at the inlet fluctuates and increases, while the pressure indicated by the pressure gauge at the outlet fluctuates and decreases. How should this be understood? I still don’t understand why both charts are showing a decline?
An increase in vacuum level should mean lower pressure, not a decrease in negative pressure! Cavitation creates bubbles, resulting in insufficient flow and a definite decrease in outlet pressure! Please ask the experts for corrections!
