 The well submersible pump is a pump suitable for clear water. It is strictly prohibited to dig new wells and pump out mud and sand. The voltage grade of the well pump is 380V/50HZ, and other voltage grades of the submersible motor need to be customized. Underground cables must be waterproof cables 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. In abnormal cases, the protective device should be tripped in time. When installing and using the pump, it must be firmly grounded. It is prohibited to push and pull the switch when the hands and feet are wet. The power supply must be cut off before installing and maintaining the pump. An obvious "anti-electric shock" sign must be set up where the pump is used. Before going down the well or installing the motor, the inner cavity must be filled with distilled water or non-corrosive clean cold water, and the water injection/drainage bolts must be tightened. Fill the pump with water for ground test to lubricate the rubber bearings. The instant start time shall not exceed one second to check whether the direction is correct and consistent with the direction indication. Be sure to pay attention to safety when placing the pump upright 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 flow at low lift or excessive pull at high lift, resulting in extreme wear of thrust bearings and other components, resulting in motor overload burn. After the pump into the well, the insulation resistance between the motor and the ground shall be measured, which shall not be less than 100MΩ. After the start, observe the voltage and current regularly, and check the motor winding insulation, to see if it meets the requirements; if the pump storage temperature is below the freezing point, the water in the motor cavity should be discharged, so as to avoid the water in the motor cavity freezing and damaging the motor due to low temperature.

The pump part is mainly composed of pump shaft,impeller,diversion shell,rubber bearing,check valve body(optional)and other components.The motor part is mainly composed of base,pressure regulating diaphragm,thrust bearing,thrust plate,lower guide bearing seat,stator,rotor,upper guide bearing seat,sand ring,water inlet section,lead cable and other components.

2.In order to prevent the sand particles in the well water from entering the motor,two oil seals are installed at the extension end of the motor shaft,and the sand ring is installed to form a sand prevention structure.
3.In order to prevent the pump shaft from jumping when starting,the pump shaft is connected with the motor shaft through a coupling,and the thrust bearing is installed at the bottom of the motor.
4.The lubrication of the motor and the pump bearing is water lubrication.

6. Schrauwen d'Waasserschrauwen un a fëllt d'Motorhuelraum mat propperem, net ätzendem Waasser (Notiz. Gitt sécher datt Dir se fillt), da dréit d'Waasserschraube fest. No 12 Stonnen Waasserinjektioun, däerf d'Isolatiounsresistenz vum Motor net manner wéi 150M Q sinn wann se mat engem 500V Schüttdësch gemooss ginn.
7. Cable joint, cut off a 120mm rubber sleeve from one end of the outgoing cable and the matching cable with an electrician's knifethen stagger the length of the three core wires in a stepped shape, peel off a 20mm copper core, scrape of the oxide layer on theoutside of the copper wire with a knife or sand cloth, and insert the two connected wire ends in palirs.

After tying the layer tightly with fine copper wire, solder it thoroughly and firmly, and sand of any. burrs on the surface. Then, forthe three joints, use polyvester insulation tape to wrap them in a semi stacked manner for three lavers. Wrap the two ends of thewrapping layer tightywith nyion thread,and then use a semi stacked method to wrap the tape for three layers. Wrap the outellayer with high-pressure insulation tape for three layers. Finally, fold the threestrands together and repeatedly wrap them for fivelayers with high-pressure tape. Each layer must be tightly tied, and the interlayer joints must be tight and fimm to prevent water frompenetrating and damaging the insulation, After wrapping, soak in water at room temperature of 20 ’c for 12 hours, and measurethe insulation resistance with a shaking table, which should not be less than 100M Ω

Dat befestegt Kabelverdrahtungsdiagramm ass wéi follegt:

(4) Saachen ze notéieren während der Installatioun:
1. If a jamming phenomenon is found during the pumping process, turn or pull the water pipe to overcome the jamming point. If various measures still do not work, please
Do not force the pump down to avoid damage to the submersible electric pump and the well.
2. Bei der Installatioun sollt e Gummi-Pad am Flange vun all Päif plazéiert ginn a gläichméisseg festgehalen ginn.
3. Wann d'Waasserpompel an d'Wuel erofgesat gëtt, sollt et an der Mëtt vun der Brunnpipe plazéiert ginn, fir datt d'Pompel net laang géint d'Wuelmauer leeft, sou datt d'Pompel vibréiert an de Motor schëdden a brennt. .
4. Bestëmmt d'Tiefe vun der Waasserpompel bis zum Buedem vun der Brunn no de fléissende Sand a Siltbedingunge vun der Brunn. Begruewen d'Pompel net am Bulli. D'Distanz vun der Waasserpompel bis zum Enn vun der Brunn ass normalerweis net manner wéi 3 Meter (kuckt Figur 2).
5. D'Waasserentrée Tiefe vun der Waasserpompel sollt net manner wéi 1-1,5 Meter vum dynamesche Waasserniveau op d'Waasserinletknuet sinn (kuckt Figur 2). Soss kënnen d'Waasserpompellager liicht beschiedegt ginn.
6. De Lift vun der Waasserpompel kann net ze niddreg sinn. Soss muss e Paartventil op der Wellhead Waasserleitung installéiert ginn fir de Pompelstroum um bewäertte Flosspunkt ze kontrolléieren fir ze verhënneren datt de Motor iwwerlaascht a verbrannt gëtt wéinst grousse Flowraten.
7. Wann d'Waasserpompel leeft, soll d'Waasserausgang kontinuéierlech sinn a souguer, de Stroum soll stabil sinn (ënner bewäertte Aarbechtsbedingunge, allgemeng net méi wéi 10% vum bewäerten Stroum), an et sollt keng Schwéngung oder Kaméidi sinn. Wann et eng Anomalie ass, sollt d'Maschinn gestoppt ginn fir d'Ursaach erauszefannen an ze eliminéieren.
8. Beim Installatioun, oppassen op d'Astellung vum Motor Buedemdraad (kuckt Bild 2). Wann d'Waasser Päif e Stol Päif ass, féiert et aus der wellhead clamp; wann d'Waasserleitung e Plastiksleit ass, féiert se vun der Äerdmarke vun der elektrescher Pompel.

• 1.Nodeems d'Tauchpompel installéiert ass, kontrolléiert d'Isolatiounsresistenz an d'Drei-Phaseleitung vum Schalter erëm, kontrolléiert ob d'Instrument an d'Verbindung vun der Startausrüstung falsch sinn, wann et kee Problem ass, kann d'Proufmaschinn gestart ginn, a beobachten ob d'Indikatorliesungen vum Instrument d'Nominalspannung a Stroum, déi op der Nummplack nom Start spezifizéiert sinn, iwwerschreiden, a beobachten ob d'Pompel Kaméidi a Schwéngungsphenomen huet, an a Betrib geholl wann alles normal ass.
