The seal clearance of the pump is too large
Thread Content
Can an excessive sealing clearance in the pump cause the pump motor to trip due to overcurrent? Please those who know explain it, thank you, bonus points
It is possible that a larger gap in the mouthpiece will lead to increased internal leakage, reducing the pump’s efficiency; to achieve the desired flow rate, it is necessary to open the outlet valve more, which in turn increases the work required of the pump
The gap is large, resulting in increased internal leakage, reduced head, decreased efficiency, and increased power consumption
Large gap, high internal leakage, high internal circulation consumption, high total flow rate, high power, and high current. Trip
With internal backflow, the load increases, but the pressure doesn’t rise and the output volume doesn’t increase either
To be precise, it is the gap around the mouthpiece that increases, not the sealing gap
An increased gap in the pump inlet ring means an increase in internal leakage; to boost flow rate, it is necessary to increase the load.
