Submersible pump usage conditions

Submersible pump usage conditions:

1. The rated frequency of the submersible pump is 50±1%HZ for the voltage and frequency of the submersible pump, and the three-phase AC power (380±5%)V (except for special order) should be guaranteed at the motor terminal voltage.

2. Submersible pump protection device The submersible pump must be equipped with an overload protection device. The rated current of the submersible pump must not exceed 1.1 times the rated current of the submersible motor.

3, submersible pumps are divided into water-filled and oil-immersed (oil-filled), water-filled submersible pump motor cavity must be filled with distilled water (or non-corrosive water),

4. Submersible pump depth The depth of deep well pump diving is not greater than 70 meters. The diving depth of QS and QY submersible pumps shall not exceed 5 meters and shall not be less than 0.5 meters.

5, solid content in water (by mass) not more than 0.01%

6. The pH of water is between 6.5 and 8.5.

7, water temperature QS, QY submersible pump water temperature does not exceed 40 °C, QJ deep well pump is not higher than 20 °C (except QJR hot water deep well pump).
