Cavitation in centrifugal pumps

How to deal with cavitation in a centrifugal pump? ! ? ? Solve? ? ? ? ?
1. Increase the pressure at the liquid level in the liquid storage tank ahead of the centrifugal pump. 2. Reduce the installation height of the suction device in front of the pump. 3. Replace the suction device with a reverse tanking device. 4. Reduce the flow losses in the pipeline before the pump
Close the outlet, and once the pressure has increased and stabilized, slowly open the outlet.
Reduce the pump’s installation height to minimize flow resistance losses
Increase the pressure head, fill the pump before starting it; ensure that the temperature of the medium at the inlet is not too high. After starting the pump, slowly open the inlet valve
