QJ long axis deep well pump structural features what?

The long shaft deep well pump is a water lifting equipment that is used to directly submerge the motor and the pump into the water and is used for irrigation of farmland and water for human and livestock in plateau and mountains. It can also be used for water supply and drainage in cities, factories, railways, mines and construction sites . Xiaobian now to introduce the structure of QJ-type long axis deep well pump What are the features? Long axis deep well pump QJ long axis deep well pump structural features 1, QJ submersible pump unit by: pumps, submersible motors (including cables), water pipes and control switch composed of four parts. Submersible pump for single-suction multi-stage vertical centrifugal pump: submersible motor for closed wet, vertical three-phase caged induction motor, motor and pump through claw or single-barrel coupling directly; equipped with different specifications of the three Core cable; starting equipment for different capacity levels of the air switch and self-dual decompression starter, water pipes made of steel pipes of different diameters, flange connection, high-lift pump gate valve control. 2, the submersible pump each stage of the diversion shell is equipped with a rubber bearing; impeller conical sleeve fixed to the pump shaft; diversion shell using threads or bolts into one. Supply 200QJ40-91 / 7 deep well pump stainless steel deep well pump long axis deep well pump 3, high lift submersible pump equipped with a check valve at the top to avoid downtime caused by water sag damage. 4, the upper part of the submersible motor shaft equipped with a labyrinth sand control and two reverse assembly of the skeleton seal to prevent the flow of sand into the motor. 5, submersible motor water lubricated bearings, the lower part with a rubber diaphragm, pressure regulating spring, the composition of the surge chamber, regulating the pressure changes due to temperature; motor winding using polyethylene insulation, nylon sheath durable consumer goods water magnet wire Cable connection by QJ-type cable connector technology, the joints off the net paint scraping net were separately connected, welded firmly, with a layer of raw rubber around. Re-use waterproof adhesive tape wrapped around 2 to 3 layers, outside the package on the 2 to 3 layers of waterproof tape or water adhesive bonded layer of rubber band (bike with) to prevent water seepage. 6, the motor closed, the use of precision bolts only, the cable outlet plus a pad to seal. 7, the motor has a water hole at the top, there is a vent, the bottom has a drain hole. 8, the lower part of the motor is equipped with thrust bearing, the thrust bearing groove for cooling, and it is stainless steel thrust plate, with the pump up and down axial force.
