Solution to Seepage of Submersible Pump

Submersible pump pipeline in use, there may be leakage of the phenomenon, the reasons for this phenomenon are generally the following, detailed solutions, please refer to the following methods.
1, the pipeline itself may be a problem, the factory did not do the pressure test, is unqualified products.
2, another possible problem is that both ends of the flange pipe connection pipe handle was not good enough, there will be leakage.
3, the third possible situation is that the flange connection bolts are not screwed in place.
Solution: defective pipe can be repaired to repair, can not be repaired to replace the installation of docking pipe center deviation should be too large to re-install the alignment, bolt alignment in the relaxed state of freedom under the screw Tightening, installation is complete, but also for leakage and pressure strength of the experiment to ensure the normal work of the deep well pump.
