How To Deal With The Motor Of An Out-tank Type Vertical Pump After It Is Damp or Flooded？
If the motor of an out-tank type vertical pump is damp or flooded, it must be dealt with as soon as possible to avoid damage to the motor and other electrical components.
Here are some steps to deal with it:
Here are some steps to deal with it:
1. Disconnect the power
Immediately cut off the power to ensure the safety of the operator and prevent short circuits or other hazards in the motor circuit.
2. Check the condition of the motor
Check whether the motor is obviously damaged, such as insulation damage, line aging, connector corrosion, etc. Confirm how the moisture entered the motor, which may be due to poor sealing or excessive humidity in the external environment.
3. Disassemble the motor
If there is moisture on the motor housing, the motor needs to be disassembled. Disassemble the motor and check for water stains and whether the internal coils, bearings, and insulation materials of the motor are wet or rusted.
4. Dry the motor
Clean up moisture: Wipe the outside of the motor with a clean rag or absorbent paper to remove visible moisture.
Drying: Place the motor in a well-ventilated area and let it dry naturally. A fan or drying equipment can be used to help speed up the drying process. Absolutely avoid using open flames to heat it to avoid damaging the motor insulation material.
If conditions permit, the motor can also be placed in an oven for low-temperature drying, generally at a temperature between 50°C and 70°C.
5. Check the motor insulation performance
After the motor is completely dry, use a megohmmeter to measure the insulation resistance of the motor. Make sure that the insulation resistance value of the motor meets the standard requirements, which should usually be no less than 1 megohm.
6. Cleaning and inspection
Check the internal parts of the motor: Check whether the bearings, rotors and stators are rusted, worn or otherwise damaged. If there is any abnormality, consider replacing the parts.
Clean the motor surface: clean the dust and debris on the motor housing, keep the motor clean and prevent water from entering.
7. Check the circuit and wiring
Check whether the electrical parts such as the motor terminals, connectors and control boxes have water stains or corrosion. If necessary, rewire or clean the contacts.
8. Restart the motor
Make sure that the motor is completely dry and all parts are back to normal before conducting a test run. Pay attention to whether the motor is working properly when starting. If there is any abnormal sound, vibration or overheating, stop running immediately and conduct further inspection.
9. Improve protective measures
If it is found that the reason for the motor to be damp or water ingress is due to poor sealing or high ambient humidity, the waterproof and moisture-proof measures of the motor should be improved in time.
If it is found that the reason for the motor to be damp or water ingress is due to poor sealing or high ambient humidity, the waterproof and moisture-proof measures of the motor should be improved in time.
Regularly check and maintain the seals, drain holes and housings of the motor to ensure that they are not damaged or blocked.
When working in an environment with high humidity, you can use moisture-proof equipment such as a humidifier or desiccant, or install a waterproof cover on the outside of the motor.
Through these steps, you can effectively reduce the damage caused by the motor being damp or water ingress and extend the service life of the motor. If you are not sure how to deal with it, you can contact a professional maintenance personnel for inspection and repair.
