 This well submersible pump is a pump suitable for clean water. It is strictly prohibited to dig new wells and pump dirty water containing sediment. The voltage grade of the pump is 380/50HZ, and other submersible motors with different voltage grades need to be customized. Underground cables must be waterproof cables and must be equipped with starting equipment, such as distribution boxes, etc. The starting equipment should have common comprehensive motor protection functions, such as short circuit overload protection, dephase protection, undervoltage protection, grounding protection and idling protection, etc., in order to prevent timely tripping when abnormal conditions occur. During the installation and use process, the pump must have reliable grounding. It is strictly prohibited to push and pull the switch when your hands and feet are wet. The power supply must be cut off before installation and maintenance of the pump. An obvious sign "anti-electric shock" must be set up where the pump is used. Before going down the well or installation, the motor must be filled with distilled water or non-corrosive clean cold water, and the water inlet and outlet bolts must be tightened. When testing the pump on the ground, water must be filled into the pump chamber to lubricate the rubber bearings. The instant start time shall not exceed one second to check whether the steering is correct. Pay attention to safety when the pump is upright to prevent toppling and injury. Strictly in accordance with the provisions of the pump lift and flow range, to prevent the pump with a large flow at low lift or produce a large pull at high lift, resulting in extreme wear of thrust bearings and other parts, the motor overload and burn. After the pump into the well, the measurement of the motor to the ground insulation resistance should not be less than 100MΩ. After starting, regularly observe the voltage and current, and check whether the motor winding insulation meets the requirements; if the pump storage temperature below freezing point, should be drained to prevent the water in the motor cavity from freezing and cause the motor damage due to low temperature.

2. Sa panahon ng pag-install, ang isang rubber pad ay dapat ilagay sa flange ng bawat pipe at higpitan nang pantay-pantay.
3. Kapag ang bomba ng tubig ay ibinaba sa balon, dapat itong ilagay sa gitna ng tubo ng balon upang maiwasan ang pagtakbo ng bomba sa dingding ng balon nang mahabang panahon, na nagiging sanhi ng pag-vibrate ng bomba at pagwalis at pagkasunog ng motor. .
4. Tukuyin ang lalim ng water pump sa ilalim ng balon ayon sa dumadaloy na buhangin at silt na kondisyon ng balon. Huwag ibaon ang bomba sa putik. Ang distansya mula sa water pump hanggang sa ilalim ng balon ay karaniwang hindi bababa sa 3 metro (tingnan ang Larawan 2).
5. Ang lalim ng pagpasok ng tubig ng water pump ay dapat na hindi bababa sa 1-1.5 metro mula sa dynamic na lebel ng tubig hanggang sa water inlet node (tingnan ang Larawan 2). Kung hindi, ang water pump bearings ay maaaring madaling masira.
6. Ang pagtaas ng water pump ay hindi maaaring masyadong mababa. Kung hindi, kailangang mag-install ng gate valve sa wellhead water pipeline para makontrol ang pump flow sa rated flow point para maiwasang ma-overload at masunog ang motor dahil sa malalaking flow rate.
7. Kapag ang water pump ay tumatakbo, ang tubig na output ay dapat na tuluy-tuloy at kahit na, ang kasalukuyang ay dapat na stable (sa ilalim ng rated working conditions, sa pangkalahatan ay hindi hihigit sa 10% ng rated current), at dapat walang vibration o ingay. Kung mayroong anumang abnormalidad, dapat na ihinto ang makina upang malaman ang sanhi at maalis ito.
8. Kapag nag-i-install, bigyang-pansin ang setting ng grounding wire ng motor (tingnan ang Figure 2). Kapag ang tubo ng tubig ay isang bakal na tubo, akayin ito mula sa wellhead clamp; kapag ang tubo ng tubig ay isang plastik na tubo, akayin ito mula sa marka ng saligan ng electric pump.
