What details should be noted in the maintenance of deep well submersible pumps

When maintaining a deep well submersible pump, attention should be paid to the following details:
Firstly, mechanical maintenance is crucial. The mechanical seal of the submersible pump should be checked regularly, and various sealing components such as sealing rings, refueling screws, sealing boxes, etc. should be inspected. For worn parts and parts with poor sealing performance, they should be repaired or replaced in a timely manner. At the same time, it is also important to prevent corrosion of submersible pumps. If the surface of the pump is damaged or peeled off, the rust should be removed in a timely manner, and anti rust paint should be applied for protection. In addition, it is necessary to regularly check the condition of the bearings of the submersible pump, including checking for oil shortage, wear, and the presence of running inner or outer rings.
Secondly, electrical inspections are equally important. The working voltage and DC current of the submersible pump should be regularly checked to ensure they are within the normal range. At the same time, check the insulation of the cables to prevent leakage. For cables, it is necessary to regularly check for any damage. If they are bitten by small animals such as mice, they should be repaired or replaced in a timely manner.
In addition, when using deep well submersible pumps, it is important to ensure sufficient water supply and avoid prolonged dry operation to prevent equipment damage. Regular cleaning of the filter is also necessary, as dirt and impurities in the water can clog the filter, affecting the normal operation of the water pump.
Finally, it is also important to keep the equipment clean. Regularly clean the outer surface of the deep well submersible pump to prevent the accumulation of dust and debris, which can affect the heat dissipation effect of the equipment.
In summary, the maintenance and upkeep of deep well submersible pumps requires attention to both mechanical and electrical details, and adherence to certain usage principles to ensure the normal operation of the equipment and extend its service life.
