 The well submersible pump is a pump suitable for clear water. It is strictly prohibited to dig new wells and pump out mud and sand. The voltage grade of the well pump is 380V/50HZ, and other voltage grades of the submersible motor need to be customized. Underground cables must be waterproof cables and must be equipped with starting equipment, such as distribution box, etc. The starting equipment should have common motor comprehensive protection functions, such as short circuit overload protection, phase loss protection, undervoltage protection, grounding protection and idling protection, etc. In abnormal cases, the protective device should be tripped in time. When installing and using the pump, it must be firmly grounded. It is prohibited to push and pull the switch when the hands and feet are wet. The power supply must be cut off before installing and maintaining the pump. An obvious "anti-electric shock" sign must be set up where the pump is used. Before going down the well or installing the motor, the inner cavity must be filled with distilled water or non-corrosive clean cold water, and the water injection/drainage bolts must be tightened. Fill the pump with water for ground test to lubricate the rubber bearings. The instant start time shall not exceed one second to check whether the direction is correct and consistent with the direction indication. Be sure to pay attention to safety when placing the pump upright to prevent overturning and causing injury. Strictly in accordance with the provisions of the pump lift and flow range of use, to prevent the pump flow at low lift or excessive pull at high lift, resulting in extreme wear of thrust bearings and other components, resulting in motor overload burn. After the pump into the well, the insulation resistance between the motor and the ground shall be measured, which shall not be less than 100MΩ. After the start, observe the voltage and current regularly, and check the motor winding insulation, to see if it meets the requirements; if the pump storage temperature is below the freezing point, the water in the motor cavity should be discharged, so as to avoid the water in the motor cavity freezing and damaging the motor due to low temperature.
