The product is supplied by three-phase AC 380V (tolerance ± 5%), 50HZ (tolerance ± 1%). Applicable water quality conditions include water temperature not exceeding 20 °C, solid impurities content (mass ratio) is not greater than 0.01%, PH value (pH) is 6.5-8.5, hydrogen sulfide content is not more than 1.5mg/L, chloride ion content is not more than 400mg/L. The motor adopts closed or water-filled wet structure. Before use, the internal chamber needs to be filled with clean water to prevent virtual filling. The pump needs to be completely immersed in water, the penetration depth shall not exceed 70m, and the distance from the bottom of the well shall not be less than 3m. The water inlet of the well shall meet the water output and continuous operation requirements of the pump, and the output of the pump shall be controlled at 0.7-1.2 times of the rated flow. The pump shall be used vertically, and the pump must be matched with the cable according to the requirements and equipped with external overload protection device. It is strictly prohibited to conduct no-load test of the pump, and it is necessary to avoid operation without water.

This well submersible pump is a pump suitable for clean water. It is strictly prohibited to pump sediment and turbid water in new wells. The voltage level of the pump is 380/50HZ. Other voltage levels of the submersible motor need to be customized. Underground cables must be waterproof 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. Under abnormal circumstances, the protection device should be tripped in time. In the process of installation and use, the pump must be reliably grounded. 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 set up a clear "anti-electric shock" mark. Before going down the well or installation, the motor must be filled with distilled water or non-corrosive cool water, and the water inlet and outlet screws must be tightened. When testing the pump, water must be injected into the pump chamber to lubricate the rubber bearings. The instant start shall not exceed one second to check whether the direction is correct. It is necessary to pay attention to the safety of the pump when it is erected to prevent it from toppling and hurting people. Strictly in accordance with the provisions of the pump lift and flow range of use, so as not to have a large flow in the low lift pump or a large pull in the high lift, causing extreme wear of thrust bearings and other components, resulting in motor overload burn. After the pump into the well, the measurement of the motor and ground insulation resistance, not less than 100M. After the start, regular observation of voltage and current, and check whether the motor winding insulation meets the requirements; if the pump storage location temperature is below freezing, storage should discharge the water in the motor cavity, to prevent the water in the motor cavity due to low temperature and freeze damage the motor.

2. O'rnatish vaqtida har bir quvurning gardish qismida kauchuk yostiq qo'yilishi va bir tekis tortilishi kerak.
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.
