 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)Priprema prije instalacije:
1. Provjerite da li potopljena pumpa ispunjava uslove upotrebe i opseg koji je naveden u priručniku.
2. Koristeći teški predmet sa prečnikom jednakim maksimalnom spoljašnjem prečniku potopljene pumpe, izmerite da li unutrašnji prečnik bušotine može da stane na potapajuću pumpu i izmerite da li dubina bunara ispunjava zahteve za instalaciju.

3. Provjerite da li je bušotina čista i da li je voda zamućena. Nikada nemojte koristiti potapajuću električnu pumpu za pranje blata i pijeska vode iz welor pumpe kako biste izbjegli prijevremeno oštećenje potopljene električne pumpe.

4. Provjerite da li je položaj stezaljke za ugradnju uglavka prikladan i da li može izdržati kvalitet cijele jedinice

5. Provjerite jesu li komponente potopljene pumpe kompletne i pravilno instalirane prema dijagramu montaže u priručniku. Uklonite filterski zaslon i okrenite spojnicu da vidite da li se fleksibilno okreće

6. Odvrnite zavrtanj za vodu i napunite šupljinu motora čistom, nekorozivnom vodom (napomena. obavezno je napunite), a zatim zategnite vodeni vijak. Nakon 12 sati ubrizgavanja vode, otpor izolacije motora ne smije biti manji od 150M Q kada se mjeri pomoću stola za tresenje od 500V.
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

Priloženi dijagram procesa ožičenja kablova je sljedeći:

8. Pomoću multimetra provjerite da li su trofazne žice povezane i da li je DC otpor približno izbalansiran.
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) Oprema i alati za instalaciju:
1. Jedan par lanaca za podizanje za više od dvije tone.
2. Stativ sa vertikalnom visinom ne manjom od četiri metra.
3. Dva viseća užad (žičana užad) koja mogu podnijeti težinu veću od jedne tone (mogu podnijeti težinu kompletne pumpe za vodu).
4. Ugradite dva para stezaljki (udlage).
5. Ključevi, čekići, odvijači, električni alati i instrumenti, itd.

(3) Instalacija električne pumpe:
1. Instalacioni dijagram potopljene električne pumpe prikazan je na slici 2. Specifične instalacijske dimenzije prikazane su u tabeli 3 "Lista instalacionih dimenzija potopljene električne pumpe".

2. Potopne električne pumpe sa naponom manjim od 30 metara mogu se dizati direktno u bunar pomoću crijeva i žičanih užadi ili drugih užadi od konoplje koja mogu podnijeti punu težinu cijele mašine, vodovodnih cijevi i vode u cijevima.

3. Pumpe sa naponom većim od 30 metara koriste čelične cijevi, a redoslijed ugradnje je sljedeći:
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 Lagano podignite potapajuću pumpu, uklonite stezaljku na gornjem kraju pumpe za vodu, zavežite kabel čvrsto za cijev za vodu plastičnom trakom i polako je zavežite dok se stezaljka ne postavi na vrh bunara.
④Upotrijebite istu metodu za vezivanje svih vodovodnih cijevi u bunar.
⑤Nakon što je izlazni kabel spojen na kontrolnu sklopku, spaja se na trofazno napajanje.

(4) Stvari na koje treba obratiti pažnju prilikom instalacije:
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. Tokom ugradnje, gumeni jastučić treba postaviti na prirubnicu svake cijevi i ravnomjerno zategnuti.
3. Kada se pumpa za vodu spusti u bunar, treba je postaviti na sredinu cijevi bunara kako bi se spriječilo da pumpa dugo radi o zid bunara, uzrokujući vibriranje pumpe, a motor da briše i gori .
4. Odredite dubinu pumpe za vodu do dna bunara u skladu sa uslovima protoka peska i mulja u bunaru. Nemojte zakopavati pumpu u blato. Udaljenost od pumpe za vodu do dna bunara općenito nije manja od 3 metra (vidi sliku 2).
5. Dubina ulaza vode u pumpu za vodu ne bi trebala biti manja od 1-1,5 metara od dinamičkog nivoa vode do ulaznog čvora vode (vidi sliku 2). U suprotnom, ležajevi pumpe za vodu mogu se lako oštetiti.
6. Podizanje vodene pumpe ne smije biti prenisko. U suprotnom, na cevovodu za vodu na ušću bunara potrebno je instalirati zasun za kontrolu protoka pumpe na nazivnoj tački protoka kako bi se sprečilo preopterećenje i izgorevanje motora usled velikih brzina protoka.
7. Kada pumpa za vodu radi, izlaz vode treba da bude kontinuiran i ravnomeran, struja treba da bude stabilna (pod nominalnim radnim uslovima, generalno ne više od 10% nazivne struje), i ne bi trebalo da bude vibracija ili buke. Ako postoji bilo kakva abnormalnost, mašinu treba zaustaviti kako bi se otkrio uzrok i otklonio ga.
8. Prilikom ugradnje obratite pažnju na podešavanje žice za uzemljenje motora (pogledajte sliku 2). Kada je cijev za vodu čelična cijev, vodite je od stezaljke na glavi bunara; kada je cijev za vodu plastična cijev, vodite je od oznake uzemljenja električne pumpe.
