Pump fault diagnosis and solution strategyIn the maintenance work, diagnosing pump fault is a crucial link. Here are a few common faults and their solutions for reference, which can help to diagnose water pump faults more accurately.
Abnormal vibration or sound: (1) The pump shaft is not concentric with the motor shaft. Solution: Adjust the pump shaft and motor shaft to ensure concentricity. (2) The anchor bolts are loose or the foundation is not firm. Solution: Tighten the anchor bolts and reinforce the foundation. (3) The bearing clearance is too large or damaged. Solution: Check and adjust the bearing clearance and replace the damaged bearing. (4) There are foreign objects in the pump casing. Solution: Inspect and remove foreign objects from the pump casing. (5) The rotating parts are unbalanced or loose. Solution: Check and balance the rotating parts and tighten the loose parts. (6) The installation height of the pump is too high, resulting in cavitation. Solution: Reduce the installation height of the pump to avoid cavitation. (7) The speed is too high. Solution: Check the motor speed to make sure it is within a reasonable range.
In the maintenance work, only by accurately diagnosing the pump can the fault problem be effectively solved and the normal operation of the pump can be ensured. At the same time, regular maintenance and maintenance are also important measures to prevent breakdowns.
