This well submersible pump is a pump suitable for clean water. Digging new wells and pumping sediment and turbid water are strictly prohibited. The voltage grade of the well pump is 380V/50HZ. Submersible motors with other voltage grades need to be customized. Underground cables must use 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 overload short circuit protection, phase loss protection, undervoltage protection, grounding protection and idling protection, etc. In abnormal cases, the protection device should be tripped in time. During installation and use, the pump must be reliably grounded. 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. The place where the pump is used must be set up with obvious "anti-electric shock" marks. Before going down the well or installation, the motor must be injected with distilled water or non-corrosive clear cold water in the inner cavity, and the intake/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 instant start time should not exceed one second to check whether the direction is correct. The same as the steering instructions. Pay attention to safety when the pump is upright to prevent tilting and injury. Strictly in accordance with the provisions of the pump lift and flow range, to prevent the pump flow at low lift or in high lift pull too large, resulting in extreme wear of thrust bearings and other components, the motor due to overload and burn. After put into the well, the measurement of the motor and the ground insulation resistance value, not less than 100M. After the start, regular observation of voltage and current, and check the motor winding insulation is in line with the requirements of the provisions. If the temperature of the storage site is below the freezing point, the water in the pump chamber should be drained to prevent the water in the motor chamber from freezing and damaging the motor due to low temperature.

2. By ynstallaasje moat in rubberen pad op 'e flange fan elke piip pleatst wurde en gelijkmatig oanskerpe.
3. As de wetterpomp yn 'e boarne ferlege wurdt, moat it yn' e midden fan 'e putpipe pleatst wurde om te foarkommen dat de pomp lang tsjin' e wellmuorre rint, wêrtroch't de pomp trillet en de motor sweep en brânt .
4. Bepale de djipte fan 'e wetterpomp nei de boaiem fan' e boarne neffens de streamende sân- en siltbetingsten fan 'e boarne. Begrave de pomp net yn 'e modder. De ôfstân fan 'e wetterpomp nei de boaiem fan' e put is oer it generaal net minder as 3 meter (sjoch figuer 2).
5. De wetteryngongsdjipte fan 'e wetterpomp moat net minder wêze as 1-1,5 meter fan it dynamyske wetterpeil nei it wetteryntreeknooppunt (sjoch figuer 2). Oars kinne de wetterpomplagers maklik skea wurde.
6. De lift fan 'e wetterpomp kin net te leech wêze. Oars, in poarte fentyl moat wurde ynstallearre op de wellhead wetter pipeline te kontrolearjen de pomp trochstreaming op de rated flow punt om foar te kommen dat de motor wurdt oerladen en útbaarnd fanwege grutte stream tariven.
7. As de wetterpomp rint, moat de wetterútfier kontinuële en sels wêze, de aktuele moat stabyl wêze (ûnder beoardielde wurkomstannichheden, oer it generaal net mear as 10% fan 'e nominearre aktuele), en der moat gjin trilling of lûd wêze. As der in abnormaliteit is, moat de masine wurde stoppe om de oarsaak te finen en it te eliminearjen.
8. By it ynstallearjen, betelje omtinken oan de ynstelling fan 'e motor grûndraad (sjoch figuer 2). As it wetter piip is in stielen piip, liedt it út de puthead clamp; as it wetter piip is in plestik piip, liedt it út 'e grûn mark fan' e elektryske pomp.

• 1.After installing the submersible pump, recheck the insulation resistance and three-phase continuity switch, check whether there is any error in the connection between the instrument and the starting equipment.If there is no problem, you can start to test the machine. After starting, observe whether the indication reading of each instrument is correct.If the rated voltage and current specified on the nameplate are exceeded, please observe whether the pump has noise or vibration.If everything is normal, it can be put into operation. After the pump runs for the first time for four hours, the motor thermal insulation resistance should be closed and tested quickly. Its value should not be less than 0.5 megaohm. After the pump stops, it should be restarted after five minutes to prevent the water column in the pipeline from completely reversing, which will cause the motor to burn out due to excessive current.
•
