Deep well submersible pump is a water lifting machine with direct connection of motor and water pump. It has the advantages of simple structure, high unit efficiency, low noise, safe and reliable operation and convenient installation and maintenance. It is suitable for extraction from deep water wells, hot water wells and oceans. It can also be used for extraction from rivers, reservoirs and canals. It is mainly used for farmland irrigation and human and livestock water in plateau mountainous areas. It can also be used for water supply and drainage in cities, factories, railways, mines and construction sites.
characteristic:
1. QJ series submersible electric pump for well is composed of submersible three-phase asynchronous motor and water pump. The motor is directly connected with the upper pump body, and a reliable shaft sealing device is set at the upper end of the motor shaft, which can effectively prevent the exchange between the coolant in the motor and the pumped medium, and ensure the long-term safe and reliable operation of the water pump.
2. Submersible pump is a single suction multistage vertical centrifugal pump; The submersible motor is a water filled wet submersible asynchronous motor for vertical wells. The motor is directly connected with the water pump through a barrel coupling.
3. The motor winding is nylon sheathed polyethylene water-resistant electromagnetic wire. Fill the motor cavity with clean water
4. The motor guide bearing adopts water lubricated bearing. The lower part of the motor is provided with a thrust bearing that can bear the upper and lower axial forces of the water pump. The thrust bearing of the high lift water pump adopts nickel copper sector block, and it is opposite to the imported Philebus sliding plate to bear the upper and lower axial forces of the water pump.
5. For high lift submersible pump, an axial load carrier is added between the pump and motor, and the lift can be increased to 900m.
