 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. Stativ z navpično višino najmanj štiri metre.
3. Dve viseči vrvi (žični vrvi), ki lahko preneseta težo več kot eno tono (lahko preneseta težo celotnega kompleta vodnih črpalk).
4. Namestite dva para sponk (splintov).
5. Ključi, kladiva, izvijači, električna orodja in instrumenti itd.

(3) Namestitev električne črpalke:
1. Namestitveni diagram potopne električne črpalke je prikazan na sliki 2. Posebne namestitvene mere so prikazane v tabeli 3 "Seznam namestitvenih mer potopne električne črpalke".

2. Potopne električne črpalke z višino manj kot 30 metrov je mogoče dvigniti neposredno v vodnjak s pomočjo cevi in ​​žičnih vrvi ali drugih vrvi iz konoplje, ki lahko prenesejo polno težo celotnega stroja, vodovodnih cevi in ​​vode v ceveh.

3. Črpalke z višino nad 30 metrov uporabljajo jeklene cevi, zaporedje namestitve pa je naslednje:
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 Rahlo privzdignite potopno črpalko, odstranite objemko na zgornjem koncu vodne črpalke, kabel trdno privežite na vodno cev s plastičnim trakom in ga počasi privežite, dokler objemka ni nameščena na ustju vodnjaka.
④Uporabite isto metodo za pritrditev vseh vodovodnih cevi v vodnjak.
⑤Ko je izhodni kabel priključen na krmilno stikalo, je priključen na trifazno napajanje.

(4) Stvari, ki jih morate upoštevati med namestitvijo:
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. Med namestitvijo je treba na prirobnico vsake cevi namestiti gumijasto blazinico in jo enakomerno zategniti.
3. Ko vodno črpalko spustite v vodnjak, jo postavite na sredino cevi vodnjaka, da preprečite, da bi črpalka dlje časa delovala ob steni vodnjaka, zaradi česar bi črpalka vibrirala, motor pa pometal in gorel .
4. Določite globino vodne črpalke do dna vodnjaka glede na razmere tekočega peska in mulja v vodnjaku. Ne zakopajte črpalke v blato. Razdalja od vodne črpalke do dna vodnjaka običajno ni manjša od 3 metrov (glej sliko 2).
5. Globina vstopa vode vodne črpalke ne sme biti manjša od 1-1,5 metra od dinamičnega nivoja vode do vozlišča vstopa vode (glej sliko 2). V nasprotnem primeru se lahko ležaji vodne črpalke zlahka poškodujejo.
6. Dvig vodne črpalke ne sme biti prenizek. V nasprotnem primeru je treba na cevovod za vodo na ustju vrtine namestiti zaporni ventil za nadzor pretoka črpalke pri nazivni točki pretoka, da se prepreči preobremenitev in izgorevanje motorja zaradi velikih pretokov.
7. Ko vodna črpalka deluje, mora biti izhod vode neprekinjen in enakomeren, tok mora biti stabilen (pri nazivnih delovnih pogojih običajno ne več kot 10 % nazivnega toka) in ne sme biti vibracij ali hrupa. Če pride do kakršnih koli nepravilnosti, je treba stroj ustaviti, da ugotovite vzrok in ga odpravite.
8. Pri namestitvi bodite pozorni na nastavitev ozemljitvene žice motorja (glejte sliko 2). Če je cev za vodo jeklena cev, jo speljite od objemke na ustju vodnjaka; če je cev za vodo plastična cev, jo speljite od oznake za ozemljitev električne črpalke.
