How to judge whether the drainage pump needs to be replaced
To determine whether the drainage pump needs to be replaced, the following aspects can be considered:
1. Aging or damage:
After long-term use, especially in harsh environments, the drainage pump may age and cause performance degradation. At this time, the degree of performance degradation of the pump should be evaluated. If it cannot meet normal drainage needs, it is necessary to consider replacement.
Pay attention to check whether key components such as the pump body, impeller, and bearings have obvious wear, cracks, or deformation.
2. Excessive noise:
If the drainage pump makes abnormal noise during operation, it may be that some parts are faulty or worn out. At this time, the machine should be stopped for inspection to find out the source of the noise.
If the fault or wear is serious and cannot be solved by maintenance, it is necessary to consider replacing the drainage pump.
3. Drop in water flow or water pressure:
When the drainage pump is running, if the water flow or water pressure drops significantly, it means that the pump's operating efficiency has decreased. This may be caused by blockage inside the pump body, wear of the impeller, or degradation of the motor performance.
You should first try to clean the inside of the pump body and check the status of components such as the impeller and motor. If normal performance cannot be restored, you need to consider replacing the drainage pump.
4. Leakage:
If the drainage pump leaks during operation, it is usually caused by damage or looseness of the sealing part. This may reduce the efficiency of the pump and even affect normal operation.
The status of the seals, such as sealing rings, gaskets, etc., should be checked first. If the damage is serious and cannot be repaired, the entire sealing part or the entire drainage pump needs to be replaced.
5. Abnormal heating:
If the drainage pump has abnormally high temperature during operation, it may be caused by poor heat dissipation or aging of the bearings. This may cause the performance of the pump to decline and even damage the motor.
The status of the heat dissipation device, such as fans, heat sinks, etc., should be checked first. If the problem cannot be solved, it is necessary to further check the status of the bearings and other components. If the bearings are seriously aged and cannot be repaired, the entire drainage pump needs to be replaced.
