【Q&A Question 160】June 9, 2018: Briefly explain why, when starting a centrifugal pump, it is not possible to open or close it quickly – why the outlet valve must be opened slowly? When starting a centrifugal pump, the outlet valve should be opened slowly to prevent a too large increase in flow rate, which could cause damage to the equipment and pipelines. Additionally, this approach allows the pump to gradually transition from no load to normal load, thereby avoiding overloading of the motor.

Preventing large fluctuations in flow rate is not conducive to stable production; Prevent the centrifugal pump from failing to deliver flow after quickly opening the valve.

When starting a centrifugal pump, the outlet valve should be opened slowly to prevent an excessive increase in flow rate, which could cause damage to the equipment and pipelines. Additionally, this approach allows the pump to gradually transition from no load to normal load, thereby avoiding overloading of the motor.

Because rapid opening and closing can damage the pump at those moments

Prevent pump cavitation and vibration in the backflow pipeline
