how to deal with mine submersible pump pump pipe fittings leakage

Daily use of mine submersible pumps in the process, we sometimes in the water pipe joints, connecting bolts, observed the phenomenon of leakage. The main reason: water pipe failure, defective, did not do the pressure test; installation of the pipeline process, the gasket is not put, the connector is not handled well, the coupling bolt is not even tightened. In response to these problems, we have to repair or even replace the defective pipes, tear off or re-arrange those centers that deviate from the larger butt joints. After aligning the hole, insert the coupling bolts into the tightening. After installing the complete piping, the pressure and the leakage test of the system are carried out.
In addition, due to mine submersible pump leakage will lead to insulation damage, bearing flooding, so that the unit to stop running, we should strengthen this precaution. The main reasons for the leakage of the pump include mechanical seal or cable inlet special seal, 0 type ring is damaged, power cable or signal cable is damaged; under normal circumstances, the protection device will promptly issued flooding, leakage, humidity and other alarm signals, Stop.
    In order to avoid the phenomenon of pump leakage, before the installation, check the motor surface with or without water leakage phenomenon, and check the quality of the sealing parts; installation must ensure that the sealing parts of the end contact is good; check the motor before and check the insulation and grounding insulation resistance and Alarm system sensor components are intact. Found in the operation of water leakage, the need to remove the relevant seals and damaged cable, put on a new.
