Deep well submersible pump maintenance method

The submersible pump is a widely used water treatment tool. The deep well submersible pump is different from the ordinary water pump. The submersible pump is a submersible pump that is directly connected to the motor and the water pump. The submersible pump can be divided into a submersible pump for wells. Working surface submersible pump, submersible sewage pump, sand submersible pump, mine vertical pump, etc. This paper discusses the maintenance methods for deep well submersible pumps.

1. Minimize the number of starts during use.

2. Check the insulation resistance of the motor every four weeks and make a record.

3. Check the current voltage and outlet pressure every day, check the water level every 2 weeks, and make a record.

4. If the deep well submersible pump is not used continuously after going down the well, it should be turned on once a week and run for 5-10 minutes to prevent the electric pump from starting due to corrosion.

5. When storing the deep well submersible pump, the water in the motor cavity should be drained, the surface should be dried, and the shaft coupling should be coated with anti-rust grease, which should be placed upright. (In case the rotor is deformed) in dry, non-chemically corrosive articles, at room temperature, the temperature during winter storage is not lower than -3 °C.

In order to ensure the normal and reliable operation of the deep well submersible pump, prolong the service life and reduce accidents during use, it is necessary to strengthen the maintenance and repair of the submersible pump, and regularly carry out comprehensive maintenance on the submersible pump and its control system, at least once a year. Preventive testing.
