The submersible pump is a well pump, composed of YQS submersible motor and QJ submersible pump. It is suitable for extracting groundwater from deep wells. It is widely used in cities, industrial and mining enterprises, cooling systems, water supply and drainage and agricultural irrigation and drainage. Its main feature is that the motor and water pump are integrated into the water to work, without the need for pump house construction, its structure is simple, easy to use and maintain, high efficiency, safe and reliable operation.

This product implementation standards are: GB/T2816-2014 "well submersible pump", GB/T2818-2014 "well submersible asynchronous motor".

Conditions of use

1. Power supply: three-phase AC 380V (tolerance 5%),50HZ (tolerance 1%).

2. Water quality:

(1) The water temperature is not higher than 20 ℃;

(2) The solid impurity content (mass ratio) is not more than 0.01;

(3)PH value (pH) 6.5-8.5;

(4) The content of hydrogen sulfide is not more than 1.5mg/L;

(5) The content of chloride ion is not more than 400mg/L.

3. The inner cavity of the submersible motor must be filled with clean water.

4, submersible pump must be completely submerged into the water to work, the depth of the submersible pump is not more than 70m, the bottom of the submersible pump from the bottom of the well is not less than 3m.

The water inflow of the well should be able to meet the water output and continuous operation of the submersible pump, and the water output of the submersible pump should be controlled at 0.7-1.2 times the rated flow.

6, the well should be upright, submersible pump can not be used horizontally, can only be used vertically.

7, submersible pump must be required to match the cable, and external overload protection device.
