(1) sand content in water shall not be greater than 0.01% (weight ratio);
(2) The pH value ranged from 6.5 to 8.5
(3) The content of chloride ion is not more than 400 mg / L. 5. It is required that the well should be positive and smooth, and there should be no staggered well pipes.
Matters needing attention:
The cable joint shall be carried out in strict accordance with the attached drawings;
1. Before going down the well, check whether the screws of each part are loose, whether the cable is broken, whether the motor is leaking, and whether the rotation of the motor shaft and water pump shaft is flexible and free of obstruction;
2. Before running into the well, check that the motor resistance should be above 150 m Ω
