Video introduction:

product description:

QJ series submersible pumps are widely used in farmland drainage and irrigation, sprinkler irrigation, well water extraction, water supply and drainage systems for industrial and civil buildings, and water diversion in hills and mountains, drainage in low-lying areas, and water supply and drainage in urban and rural industrial and mining enterprises. . Its characteristics are that the motor and water pump are assembled into one body, with simple structure, convenient installation and disassembly, small footprint, simple use and maintenance, safe and reliable operation, and no pollution to water sources.

Conditions of Use:

38OV 偏差不超过 ±5% ,频率 50HZ ,偏差不超过 ±1 %的三相电源。 1 Three-phase power supply with voltage deviation of not more than ± 5% , frequency of 50HZ , and deviation of not more than ± 1 %.

2. The inner cavity of the motor must be filled with water.

2m 以下。 3. The first stage impeller of the pump should be immersed at least 2m below the moving water level surface . 70m ,电机底部距井底不得小于 3m The immersion of the electric pump unit below the static water level shall not be greater than 70m , and the bottom of the motor shall not be less than 3m from the bottom of the well .

20℃ 4. The water temperature is not higher than 20 ℃ .

0.01 %。 5. The sand content of the water (according to mass) is not more than 0.01 %.

PH 6.5-8.5 6 , pH value of water 6.5-8.5 .

1.5mg/l 7. The content of hydrogen sulfide in water is not more than 1.5mg / l .

400mg/l 8. The content of chloride ion in water is not more than 400mg / l .

9 , the amount of water from the water source should ensure the need for continuous operation of the electric pump.


Structural characteristics and working principle:

QJ submersible electric pump is a high-efficiency and energy-saving water-lifting tool that combines a pump and a pump to work in the water. It consists of a submersible motor, a pump, and a riser. The interior is filled with clean water. For cooling motors and lubricating bearings. / 多级离心闭式叶轮,导流壳输送液体。 The motor winding is made of polyethylene insulated nylon sheathed water-resistant electromagnetic wire. The upper part of the motor is sealed with a sand sling ring and a skeleton oil seal to prevent leakage of the medium inside and outside the motor . The shell conveys liquid.
