QJ deep well submersible pump

口径2-230：

扬程1-65米

The deep well submersible pump is a water-lifting device that works directly in the water with a motor and a water pump directly connected together. It is composed of a submersible pump, a submersible motor, a water pipe cable and a starting protection device. It is suitable for extracting groundwater from deep wells, and can also be used in water lifting projects such as rivers, reservoirs and canals.
Deep well submersible pumps
It is mainly used for farmland irrigation and water for humans and animals in plateau mountains. It can also be used for urban factories, railways and mining sites. For drainage use.
b Three-phase AC power supply with power frequency and rated voltage of tolerance +.
rb
The solid content shall not be greater than by mass.
The acidity value of the pumped liquid is.
The temperature of the conveying medium does not exceed ℃.
The water inlet of the water pump must be below the dynamic water level, but the diving depth should not exceed the static water level. The distance between the lower end of the electric pump and the bottom of the well is the least.
The well is required to be straight, the well wall is smooth, and the well pipe must not be staggered.

The series of well submersible electric pumps are composed of two parts: a submersible three-phase asynchronous electric pump and a water pump. The motor is directly connected to the pump body above it. The upper end of the motor shaft is equipped with a reliable shaft seal device, which can effectively prevent the exchange between the coolant in the motor and the pumped medium, ensuring the long-term safe and reliable operation of the water pump.
The submersible pump is a single-suction multi-stage vertical centrifugal pump and the submersible motor is a water-filled wet vertical well submersible asynchronous motor. The motor and water pump are directly connected through a barrel coupling.
The motor windings are nylon-sheathed polyethylene water-resistant electromagnetic wires. Just fill the motor cavity with clean water
The motor guide bearing adopts water-lubricated bearings. There is no thrust bearing in the lower part of the motor that can withstand the up and down axial force of the water pump. The thrust bearing of the high-lift water pump uses a nickel-containing copper sector block, and it is ground with an imported Philerbus slide to bear the up and down axial force of the water pump. .
