Introduction

One, a brief introduction
QJ series well pump, deep well pump, apply to the extracted from deep groundwater, can also be used for rivers, reservoirs, canals and other water projects. It is mainly used for farmland irrigation and high mountain water, can also cities, factories, railways, mines, construction site drainage.
Second, the QJ series Wells with submersible electric pump features:
1, motor, water pump, body, run into the water, safe and reliable.
2, no special requirements for well tube, Yang pipes as long as it can bear the pressure.
3, installation is convenient in operation and maintenance is simple, cover an area of an area small, do not need to build the pump room.
4, simple structure, saves the raw material.
Three, use of the environment and working conditions
1, the power frequency 50 hz, the use of the rated voltage of 300 v or 660 v (tolerance of + / - 5%) of the three-phase ac power supply.
2, solid content (in quality) is not greater than 0.01%.
3, by pumping liquid pH pH 6.5 8.5.
4, medium temperature not to exceed 20 ℃.
5, water pump inlet must be under dynamic water level 1 m, but the diving depth is less than the static water level below 70 m, pumps from bottom bottom hole depth of at least 1 m.
6, demand upright well tube, wall smooth, well tube shall not stagger.
Four, structure features
1, QJ series Wells with submersible pumps, consists of two most, dive three-phase asynchronous motor and pump. Motor pump with its upper body straight, the motor shaft top a reliable shaft sealing device, can effectively prevent the cooling fluid for electric motor and the exchange between pumping medium, guarantee the pump running safely and reliably for a long time.
2, submersible pump is single-suction multi-stage vertical centrifugal pump; Submersible motor for filling water wet, vertical Wells with diving asynchronous motor. The motor and pump through drum coupling straight league.
3, motor winding for polyethylene water resistant nylon sheathed electromagnetic wire. Motor cavity filled with clean water.
4, guide bearing with water lubricated bearing of the electrical machinery. Lower part of the motor can afford to pump up and down the axial force of the thrust bearing, high lift water pump of thrust bearing with nickel copper fan, and it is import for the grinding of Loeb, skateboard, can withstand the water pump and axial force.
5, young Cheng Qian water pump in the middle of the pump and motor bearing device, additional axial force head can be raised to 900 m.
Five, the use matters needing attention
Inside the QJ series submersible motor, rear can run must be filled with clean water, in the winter when stopping stored should be no net water filling machine, to prevent the frost crack.
2, regular inspection units, insulation resistance shall be not less than 0.5 M Ω.
3, normal use warranty for one year.
