Description of deep well submersible pump structure

deep well submersible pump is the biggest characteristic of the motor and pump into one, it is immersed in underground water wells for pumping and conveying water of a pump, is widely used in farmland irrigation and drainage, industrial and mining enterprises, urban water supply and drainage and sewage treatment. There is no special requirement for the well pipe and the water pipe (ie, the steel pipe well, the ash pipe well, the soil well and so on can be used; under the pressure permission, the steel pipe, the hose, the plastic pipe and so on may serve as the water pipe). Installation, use, easy maintenance simple, small footprint, no need to build pump room.
deep well submersible pump structure description:
Diving deep well pump motor and pump directly into the water into the work of water lifting equipment, it is suitable for extraction from the deep wells of groundwater can also be used for rivers, reservoirs, canals and other water works, then we know what the structure is it? It is about the structure of the submersible deep well pump.
1, diving deep well pump unit consists of: water pump, submersible motor (including cable), water pipes and control switch composed of four parts.
Diving deep well pump pump is a single suction multi-stage vertical centrifugal pump: submersible motor for the closed water-filled wet, vertical three-phase cage asynchronous motor, motor and pump through the claw or single drum coupling directly; equipped with different specifications Three-wire cable; starting equipment for different capacity levels of air switch and self-decompression starter, the water pipe for the different diameter of the steel pipe made of flange connection, high-lift pump with gate valve control.
2, diving deep well pump each stage containing a rubber bearing; impeller with a conical sleeve fixed on the pump shaft; diversion shell with threads or bolts into one.
3, high-lift submersible pump equipped with a check valve, to avoid downtime caused by damage to the unit.
4, submersible motor shaft with a labyrinth sandstand and two reverse assembly of the skeleton oil seal, to prevent the flow of sand into the motor.
5, the submersible motor with water lubricated bearings, the lower part of the rubber pressure regulating film, pressure regulating spring, composed of surge chamber, adjust the pressure caused by temperature changes; motor winding with polyethylene insulation, nylon jacket durable consumer goods water , Cable connection by QJ-type cable connector technology, the connector insulation off scraping paint layer, were connected, welding firmly, with raw rubber around a layer. And then wrapped with water-resistant adhesive tape 2 to 3 layers, outside the package on the 2 to 3 layers of waterproof tape or glue with a layer of rubber tape (bike belt) to prevent water seepage.
6, the motor is sealed, the use of precision stop bolts, cable outlet plus gasket for sealing.
7, the motor has a water hole at the top, there is a vent hole, the lower part of a water hole.
8, the lower part of the motor with the upper and lower thrust bearings, thrust bearings on the groove for cooling, and it is grinding stainless steel thrust plate, with the pump up and down axial force.
