Features and principles of high lift submersible water pumps

Features and principles of high lift submersible water pumps

The characteristics and principle of young pump release date young pump features:AT540QJ mine submersible pump series features:

1, motor, water pump, body, run into the water, the Mars, explosion-proof, safe and reliable.

2, no special requirements for well tube, for delivery as long as can withstand the pressure can be accordingly.

3, installation maintenance convenience simple, cover an area of an area small, do not need to build the pump room.

4, simple structure, saves the raw material.

5, high efficiency, energy saving, single-stage high head, large flow, high head, imported high efficiency and energy saving motor, such as: Germany AT200QJ series submersible motor can do 110 kw (maximum overall diameter 184 mm), level 2 speed 410 kw (2900 / min) can do

Using the environment and conditions1, power frequency 50 hz, rated voltage of 300 v or 660 v or high voltage 6 kv, 10 kv (tolerance of + - 5%) of three-phase ac power supply.2, solid content (in quality) is not greater than 0.01%.3, shout by pumping liquid acid degree of PH value of 6.5 to 6.5.4, medium temperature not to exceed 20 ℃.5, water pump inlet must be below the water level dynamic lm, but diving depth is less than the static water level to 70 m, electric pump bottom hole depth at least lm.6, requirements well integrity, wall smooth, well tube shall not stagger. Structural characteristics of1, ATQJ mine submersible pump series, consists of two most, diving three-phase asynchronous electric and water 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. 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 cannot bear water pump 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, inherit and axial force of pump.5, young water pump in the middle of the pump and motor additional axial force bearing, head can be raised to 1500 m.
