SJ/QJ Submersible pump
The most professional manufacture of submersible pump and motor in china high efficiency, lower noise, long service life ,lower price with good quality. Popular in over 80 countries all over the world.
Brief introduction
The bore well submersible pump unit is composed of the motor and pump together which is placed in the bore well by connecting the motor cable withe the power supply which drives the impeller rotating. It's simple and small light-weight structure easy to maintain.it runs in a good condition and performs well .
This is new highly efficient machine and low cost for water supply. It can be used for drainage in mines,
a city's water supply, clean water ,irrigation and potable water and animals areas lacking water .
Work condition
1.Voltage: 380V
2.Frequency:50HZ(3phase AC)
3.Water temperature≤20°C
4.The sand content of the well water (weight ratio) should not be over 0.01% PH:6.5—8.5.
5.The pump units should be immersed below the dynamic water level.
Structure features
Pump: The pump is installed on the upper part of the pump units. It's centrifugal and has water lubricated bearing mounted with the motor shaft by a joint.
There is a check valve on top of the pump which could prevent rapid inverse rotation from backward flow.
The pump unit should be immersed below the dynamic water level when in using.
Motor: the motor is installed under the pump.
It is a water filled in hermetical structure. The stator windings are water-tight and PE insulating and multi-layers are covered with nylon.
The motor bearing is water-lubricated.
The inner motor contains clean water to cool the water body and the bearing.
The rubber diaphragm adjusts the pressure change caused when temperature rises.
There is a sand resistance system in the upper part of the motor.
