 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.

(1) Voorbereiding voor installasie:
1. Kontroleer of die dompelpomp voldoen aan die gebruiksvoorwaardes en omvang gespesifiseer in die handleiding.
2. Gebruik 'n swaar voorwerp met 'n deursnee gelyk aan die maksimum buitenste deursnee van die dompelpomp, meet of die binnedeursnee van die boorput by die dompelpomp kan pas, en meet of die putdiepte aan die installasievereistes voldoen.

3. Kontroleer of die boorput skoon is en of die putwater troebel is. Moet nooit 'n dompelpomp gebruik om die welor pomp modder en sand water te was om voortydige skade aan die dompel elektriese pomp te vermy.

4. Kontroleer of die posisie van die putkopinstallasieklem geskik is en of dit die kwaliteit van die hele eenheid kan weerstaan

5. Kontroleer of die dompelpompkomponente volledig en behoorlik geïnstalleer is volgens die samestellingsdiagram in die handleiding Verwyder die filterskerm en draai die koppeling om te sien of dit buigsaam draai

6. Skroef die waterskroef los en vul die motorholte met skoon, nie-korrosiewe water (let wel. maak seker dat jy dit vol maak), draai dan die waterskroef vas. Na 12 uur se waterinspuiting moet die isolasieweerstand van die motor nie minder as 150M Q wees as dit gemeet word met 'n 500V skudtafel nie.
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

Die aangehegte kabelbedradingsprosesdiagram is soos volg:

8. Gebruik 'n multimeter om te kyk of die driefase-drade verbind is en of die GS-weerstand ongeveer gebalanseerd is.
9. Check whether the circuit and transformer capacity are overloaded, and then connect the overload protection switch or starting equipment. See Table 2 for specific models, and then
Pour a bucket of water into the water pump from the water pump outlet to lubricate the rubber bearings in the pump, and then place the submersible electric pump upright and steady.
Start (no more than one second) and check whether the steering direction is consistent with the steering sign. If not, swap any two connectors of the three-phase cable.
Then install the filter and prepare to go down the well. If used in special occasions (such as ditches, ditches, rivers, ponds, ponds, etc.), the electric pump must be reliably grounded.

(2) Installasie toerusting en gereedskap:
1. Een paar hyskettings vir meer as twee ton.
2. 'n Driepoot met 'n vertikale hoogte van nie minder nie as vier meter.
3. Twee hangtoue (draadtoue) wat 'n gewig van meer as een ton kan dra (kan die gewig van 'n volledige stel waterpompe dra).
4. Installeer twee pare klampe (spalke).
5. Sleutels, hamers, skroewedraaiers, elektriese gereedskap en instrumente, ens.

(3) Elektriese pompinstallasie:
1. Die installasiediagram van die dompel-elektriese pomp word in Figuur 2 getoon. Die spesifieke installasie-afmetings word in Tabel 3 "Lys van Installasie-afmetings van die dompel-elektriese pomp" getoon.

2. Dompelbare elektriese pompe met 'n hoogte van minder as 30 meter kan direk in die put gehys word deur gebruik te maak van slange en draadtoue of ander henneptoue wat die volle gewig van die hele masjien, waterpype en water in die pype kan dra.

3. Pompe met 'n hoogte van meer as 30 meter gebruik staalpype, en die installasievolgorde is soos volg:
①Use a clamp to clamp the upper end of the water pump part (the motor and water pump have been connected at this time), lift it with a hanging chain, and slowly tie it into the well until
Put the clamp on the wellhead and remove the hanging chain.
② Use another pair of clamps to clamp a pipe, lift it with a hanging chain 15 cm away from the flange, and lower it slowly. Between pipe flange and pump flange
Put the rubber pad in place and tighten the pipe and pump evenly with bolts, nuts and spring washers.
③ Lig die dompelpomp effens op, verwyder die klem aan die boonste punt van die waterpomp, bind die kabel stewig aan die waterpyp vas met 'n plastiekband, en maak dit stadig vas totdat Die klem by die putkop geplaas is.
④Gebruik dieselfde metode om alle waterpype in die put vas te bind.
⑤ Nadat die uitloopkabel aan die beheerskakelaar gekoppel is, word dit aan die driefase-kragbron gekoppel.

(4) Dinge om op te let tydens installasie:
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. Tydens installasie moet 'n rubberkussing by die flens van elke pyp geplaas word en eweredig vasgedraai word.
3. Wanneer die waterpomp in die put laat sak word, moet dit in die middel van die putpyp geplaas word om te verhoed dat die pomp vir 'n lang tyd teen die putwand loop, wat veroorsaak dat die pomp vibreer en die motor vee en brand .
4. Bepaal die diepte van die waterpomp tot by die bodem van die put volgens die vloeiende sand- en sliktoestande van die put. Moenie die pomp in die modder begrawe nie. Die afstand vanaf die waterpomp na die bodem van die put is oor die algemeen nie minder nie as 3 meter (sien Figuur 2).
5. Die watertoevoerdiepte van die waterpomp moet nie minder nie as 1-1,5 meter wees vanaf die dinamiese watervlak na die waterinlaatknooppunt (sien Figuur 2). Andersins kan die waterpomplaers maklik beskadig word.
6. Die hysbak van die waterpomp kan nie te laag wees nie. Andersins moet 'n hekklep op die putkopwaterpyplyn geïnstalleer word om die pompvloei by die aangewese vloeipunt te beheer om te verhoed dat die motor oorlaai en uitbrand as gevolg van groot vloeitempo's.
7. Wanneer die waterpomp aan die gang is, moet die wateruitset aaneenlopend en eweredig wees, die stroom moet stabiel wees (onder gegradeerde werksomstandighede, gewoonlik nie meer as 10% van die aangeslane stroom), en daar moet geen vibrasie of geraas wees nie. As daar enige abnormaliteit is, moet die masjien gestop word om die oorsaak uit te vind en dit uit te skakel.
8. Wanneer jy installeer, let op die instelling van die motor se aarddraad (sien Figuur 2). Wanneer die waterpyp 'n staalpyp is, lei dit uit die putkopklem; wanneer die waterpyp 'n plastiekpyp is, lei dit vanaf die aardmerk van die elektriese pomp.
