Overcurrent in centrifugal pump, reasons for centrifugal pump tripping

Thread Content

Reasons for overcurrent in centrifugal pumps, reasons for tripping due to overcurrent in centrifugal pumps? 1. The power of the motor used with the centrifugal pump is too low ； Solution: Adjust the accessories and replace the motor. Reasons for excessive current in centrifugal pumps: 2. Excessively high rotation speed of the water pump ； Solution: Reduce the pump speed. 3. Pump shaft bent, bearings worn or damaged ； Solution: Align the pump shaft and repair or replace the bearings. 4. The filler is compressed too tightly ； Solution: Loosen the filler gland. 5. The actual operating head is much lower than the pump’s head, resulting in an excessive flow rate ； Solution: Reduce the outlet valve to control the water pump flow. 6. The couplings are not aligned, or the gap between them is too small ； Solution: Correct the concentricity or adjust the gap between the couplings. 7. Long shutdown time leads to thermal expansion, reducing friction in the seal ring ； Solution: Follow the standard operating procedures; in case of a malfunction, stop the machine immediately for inspection. 8. The motor became damp due to being submerged in water ； Solution: Dry the damp motor.
