 This well submersible pump is a clean water pump. It is strictly prohibited to dig new wells and extract sediment and turbid water. The voltage grade of the well pump is 380/50HZ. Other submersible motors with different voltage grades need to be customized. Underground cables must be waterproof and equipped with starting equipment, such as distribution boxes, etc. The starting equipment should have conventional comprehensive motor protection functions, such as short circuit overload protection, phase loss protection, undervoltage protection, grounding protection and idling protection. In abnormal cases, the protection device should be tripped in time. The pump must be reliably grounded when installed and used. It is prohibited to push and pull the switch when the hands and feet are wet. The power must be cut off before installation and maintenance of the pump. The place where the pump is used must be clearly marked with "anti-electric shock". Before going down the well or installation, the motor must be filled with distilled water or non-corrosive clean cold water. The intake/drain bolts must be tightened. When testing the pump on the ground, water must be added to the pump chamber to lubricate the rubber bearings. The instantaneous start should not exceed one second to check whether the direction is correct. This is also applicable to direction indication. When using the vertical electric pump, pay attention to safety to prevent overturning and injury. Strictly in accordance with the provisions of the pump lift and flow range of use, to prevent the pump in low lift has a large flow or high lift has a large pull, resulting in extreme wear of thrust bearings and other parts, so that the motor overload burned. After the pump into the well, the measurement of the insulation resistance between the motor and the ground shall not be less than 100MΩ. After the start, regular observation of voltage and current, and check whether the motor winding insulation meets the requirements of the provisions. If the pump storage location temperature is below freezing, the water in the motor cavity should be drained to prevent freezing in the motor cavity and damage the motor due to low temperature.

• （1）After the submersible pump is installed, check the insulation resistance and three-phase conduction from the switch again, check whether the instrument and the connection of the start equipment are wrong, if there is no problem, the trial machine can be started, and observe whether the indicator readings of the instrument exceed the rated voltage and current specified on the nameplate after the start, and observe whether the pump has noise and vibration phenomenon, and put into operation if everything is normal.
• （2）After the first operation of the pump for four hours, the motor should be shut down to test the thermal insulation resistance quickly, and its value should not be less than 0.5 megaohm.
• （3）After the pump is shut down, it should be started after five minutes to prevent the water column in the pipe from being completely reflowed and causing excessive motor current and burnout.
• （4）After the pump is put into normal operation, in order to prolong its service life, it is necessary to check whether the supply voltage, working current and insulation resistance are normal regularly. If the following conditions are found, the pump should be shut down immediately to troubleshoot.
