Stainless steel submersible pump main features and structure introduction

Stainless steel submersible pump stainless steel submersible pump is directly connected to the motor and pump submersible work in the water lifting equipment, which is suitable for extraction of groundwater from deep wells, can also be used for rivers, reservoirs, drains and other water projects. Mainly used for farmland irrigation and plateau mountain water for human and livestock, but also for the city, factories, railways, mines, site water supply and drainage. Now to introduce the main features and structure of stainless steel submersible pump. Stainless steel submersible pump A stainless steel submersible pump Main features 1. Motor, pump body, submerged in water running, safe and reliable. 2. No special requirements for well pipe and lifting pipe (ie: steel tube well, gray tube well, soil well, etc. can be used; Under the pressure permit, steel pipes, hoses, plastic pipes, etc. can be used for pumping pipes). 3. Installation, use, easy maintenance, small footprint, no need to build pump room. 4. Simple structure, saving raw materials. Submersible pump conditions are appropriate, properly managed and have a direct relationship with the service life. Second, stainless steel submersible pump structure 1. Submersible pump unit by: pumps, submersible motor (including cables), water pipes and control switch composed of four parts. Submersible pump for single-suction multi-stage vertical centrifugal pump: Submersible motor is sealed wet-type, vertical three-phase squirrel cage different motor, motor and pump through the claw or in. Keyhole coupling direct; equipped with a different Specifications of the three-core cable: starting equipment for different levels of capacity of the air switch and auto decompression starter, water pipes made of steel pipes of different diameters, flange connection, high-lift pumps preclude the use of gate valve control. 2. The submersible pump is equipped with a rubber bearing in each stage of the diversion shell; the impeller is fixed on the shaft by a conical sleeve: the diversion shell is integrated with a rib or bolt. 3. High-lift submersible pump installed in the upper part of the check valve to prevent water hammer damage caused by unit damage. 4. The upper part of the submersible motor shaft is equipped with a labyrinth sand control and two reverse-mounted skeleton oil seals to prevent the runner from entering the motor. 5. Submersible motor water lubricated bearings, the lower part with a rubber diaphragm, pressure regulating spring, the composition of the pressure regulating chamber, adjust the pressure changes due to temperature; motor winding using polyethylene insulation, nylon sheath waterproof wire, cable connection Way by QJ-type cable connector technology, the joint off the net paint scraping net were separately connected, welded firmly, with raw rubber around the layer. Re-use waterproof adhesive tape wrapped around 2 to 3 layers, outside the package on the 2 to 3 waterproof tape or water adhesive bonding layer of rubber band (bicycle tire) to prevent water seepage. 6. Motor closed, the use of precision screw mouth only, the cable outlet plus a private supplementary school for sealing. 7. The motor has a water hole on the top, there is a vent, BU Department put a water hole. 8. The lower part of the motor is equipped with a thrust bearing, a thrust bearing with grooves for dry cooling, and a stainless steel thrust plate for grinding it.
