Reasons for the centrifugal pump to trip
Thread Content
Could everyone please help explain the reasons for an overload-induced shutdown of a centrifugal pump during normal operation? Thank you
There are mainly two reasons for the centrifugal pump to shut down: 1. The flow rate exceeds the specified value, causing the motor to overcurrent and shut down. This can be controlled by adjusting the outlet valve of the centrifugal pump to maintain an appropriate flow rate. 2. Mechanical failure: increased bearing friction leads to motor overload and shutdown; the pump needs to be stopped for maintenance.
What was said upstairs makes sense: victory:
1. Large voltage fluctuations, overcurrent; 2. Motor failure; 3. Phase loss, overcurrent, or issues with electrical wiring; 4. Damage to the bearings or blades of the motor or pump. Last edited by Dong Chenyuan on 2007-12-27 at 17:29.]
It could also be due to an unbalanced shaft connection between the motor and the pump, which results in excessive load and causes the machine to shut down. Alternatively, it might be caused by a detached or damaged seal ring on the pump, among many other possible reasons.
It’s usually caused by excessive load; check your operating current
If it shuts down when there is no load, that indicates a problem. You can disconnect the coupling connected to the pump and start the motor to see whether the issue lies with the electrical components or the pump itself. It’s not possible for us to provide an explanation based on the information you’ve given; it would be better if you could provide the electrical diagram as well as the motor’s power specifications
