Several basic knowledge points to pay attention to in water pump maintenance

1、 Common faults of water pumps

1. The water pump cannot start normally

Fault analysis: If the power supply of the water pump is normal, the failure to start may be due to damage to the control circuit or power supply, and it may also be due to a malfunction of the motor itself.

Troubleshooting method: First, check the power supply and control circuit to see if they need to be replaced or repaired. If the problem with the power supply and control circuit is ruled out, the motor needs to be checked.

2. Water pump leaking

Fault analysis: Common faults are aging or wear of seals, and it is also possible that water leakage is caused by mechanical seals, shaft seals, or loose connecting screws.

Troubleshooting method: First, turn off the water pump, check the specific location of the leakage, determine the problem, and then repair or replace it according to the specific problem.

3. Abnormal sound during water pump operation

Fault analysis: Usually caused by damage to bearings or bearing seats.

Troubleshooting method: Check the condition of the bearings or bearing seats to see if they need to be replaced or repaired.

2、 Maintenance precautions

1. Be sure to cut off the power supply before maintenance to avoid electric shock accidents.

2. When carrying out maintenance, the required spare parts should be selected and replaced based on the specific model, operating environment, and working conditions of the water pump. Non original parts or parts without guaranteed quality should not be used arbitrarily.

3. When disassembling the water pump, it is important to carry certain tools to prevent unnecessary damage or accidents during disassembly. At the same time, attention should be paid to the disassembly sequence and steps to ensure a smooth maintenance process.

4. When disassembling the water pump after maintenance, pay attention to checking the tightness of each part to ensure safe use.

5. After reassembly, the seal should be replaced, and good sealing materials should be selected as much as possible. Pay attention to the direction of seal assembly and do not install it in the opposite direction.

In short, for the maintenance of water pumps, we need certain professional skills and experience, and try to repair them in the original factory or professional institutions as much as possible to ensure the quality and safety of use. At the same time, in daily use, attention should also be paid to strengthening maintenance, timely detection and resolution of faults, in order to extend the service life of the equipment.

Summary: This article introduces common faults and maintenance precautions of water pumps, hoping to provide some reference and assistance for personnel who need to repair water pumps.
