The motor adopts a closed or water-filled wet structure, the inner cavity must be filled with clean water before use to prevent false filling. The pump must be completely immersed in water, and the immersion depth shall not exceed 70m, the distance from the bottom of the pump and the bottom of the well shall not be less than 3m. The water source shall meet the requirements of the pump inflow and continuous operation, the pump water control in the rated flow of 0.7-1.2 times. The well must be vertical, the pump can not be used horizontally or tilted, only vertical use. The pump must be equipped with cables and external overload protection device as required. It is strictly prohibited to dry turn the pump test. The design of the equipment is safe and reliable, meets the use of standards, is an indispensable ideal choice in all kinds of engineering projects and industrial applications.

This well submersible pump is designed for clean water. It is strictly prohibited to discharge sediment and mud in the newly drilled well. The voltage standard of the submersible pump is 380/50HZ. Other voltage levels of the submersible motor need to be customized. Underground cables must be waterproof and equipped with start-up equipment, such as distribution box, etc. Start-up equipment should have common motor comprehensive protection functions, such as short circuit overload protection, phase loss protection, undervoltage protection, grounding protection, idling protection, etc., so that the protection device can trip in time in case of abnormal conditions. The pump must be reliably grounded during installation and use. It is prohibited to push and pull the switch when hands and feet are wet. The power supply must be cut off before installation and maintenance of the pump. An obvious "anti-electric shock" sign must be set up where the pump is used. Before going down the well or installation, the inner cavity of the motor must be filled with distilled water or non-corrosive clean cold water, and the water / drain bolts must be tightened. When testing the pump on the ground, water must be injected into the pump chamber to lubricate the rubber bearings. The instantaneous start time shall not exceed one second to check whether the steering is correct, as indicated by the steering indicator. Pay attention to safety and ensure that the pump is erected 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 with a large flow at low lift, or at high lift with a large pull, resulting in extreme wear of thrust bearings and other parts, the motor overload burnout. After the pump into the well, the need to measure the insulation resistance of the motor and the ground, not less than 100MΩ. After the start, regular observation of voltage and current, check whether the motor winding insulation meets the requirements of the provisions. If the temperature of the storage location is lower than the freezing point, the water in the motor cavity should be drained to prevent the water in the motor cavity from freezing and damaging the motor due to low temperature.

3. Suv nasosi quduqqa tushirilganda, nasosning quduq devoriga uzoq vaqt davomida ishlamasligi, nasosning tebranishi va dvigatelning supurib yonishiga olib kelishi uchun uni quduq trubasining o'rtasiga qo'yish kerak. .
4. Quduqning oqayotgan qum va loy sharoitiga qarab suv nasosining quduq tubiga chuqurligini aniqlang. Nasosni loyga ko'mmang. Suv nasosidan quduq tubigacha bo'lgan masofa odatda 3 metrdan kam emas (2-rasmga qarang).
5. Suv nasosining suvga kirish chuqurligi dinamik suv sathidan suv kirish tuguniga qadar 1-1,5 metrdan kam bo'lmasligi kerak (2-rasmga qarang). Aks holda, suv nasosining podshipniklari osongina shikastlanishi mumkin.
6. Suv nasosining ko'tarilishi juda past bo'lishi mumkin emas. Aks holda, katta oqim tezligi tufayli dvigatelning haddan tashqari yuklanishi va yonib ketishining oldini olish uchun nominal oqim nuqtasida nasos oqimini nazorat qilish uchun quduq bo'yidagi suv quvur liniyasiga eshik klapanini o'rnatish kerak.
7. Suv pompasi ishlayotganida, suv chiqishi uzluksiz va bir tekis bo'lishi kerak, oqim barqaror bo'lishi kerak (nominal ish sharoitida, odatda nominal oqimning 10% dan ko'p bo'lmagan) va tebranish yoki shovqin bo'lmasligi kerak. Agar biron bir anormallik bo'lsa, sababni aniqlash va uni bartaraf etish uchun mashinani to'xtatish kerak.
8. O'rnatishda vosita topraklama simini sozlashga e'tibor bering (2-rasmga qarang). Suv trubkasi po'lat quvur bo'lsa, uni quduqning qisqichidan olib boring; suv trubkasi plastik quvur bo'lsa, uni elektr nasosning topraklama belgisidan olib boring.
