Submersible pump should be how specific maintenance

Submersible pump is a major water pumping device, then how should the repair and maintenance of it? The following by the Shanghai Submersible Pump manufacturers and we talk about, but also to provide a reference.

Before using the maintenance

1, submersible pump if not used for a long time and on the water when used before the pump from the machine downhole or other waters put up to check the parts, rust paint, to prevent corrosion of parts.

2, running 2-3 years of submersible pumps, pumps and motors should be removed, cleaning all the parts, but also remove the screws, cleaning the impeller in the chamber of sediment and debris.

3, check the pump and motor bearings, impeller ring, thrust bearings, thrust plate and other vulnerable parts, wear serious to be replaced.

4, check the pump on the fasteners, rust slowly unscrew, ritual a little oil , damaged to be replaced.

5, check the sealing parts of the pump, and some because of friction and washer rot, water into the sealed cavity, so that the rotating parts rust and not flexible or simply turn fixed. For the corrosion of the moving parts and damaged seals, to re-replace the new pieces.

6, to check the cleaning and repair parts, re-assembly together. Assembly, the bonding surface and the fastening body should be coated with butter, to prevent rust, affecting the next demolition.

If after a few steps above the maintenance, submersible pumps can basically be used normally.

If there is need to store, then the storage should be how to maintain it? Here we continue to say.

1, when not in use, the pump should be stored in the ventilation drying room, so as not to damp motor.

2, wet submersible pump storage in winter before storage, you must let go of the internal lubrication of the motor cooling water, so as not to freeze frozen bad motor.
