1. En par dvižnih verig za več kot dve toni.
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:
①Uporabite objemko, da vpnete zgornji konec dela vodne črpalke (motor in vodna črpalka sta bila trenutno povezana), jo dvignite z visečo verigo in počasi privežite v vodnjak, dokler ne namestite objemke na glavo vodnjaka in odstranite viseča veriga.
② Uporabite drug par sponk, da vpnete cev, jo dvignite z visečo verigo 15 cm stran od prirobnice in jo počasi spustite. Med prirobnico cevi in ​​prirobnico črpalke Namestite gumijasto podlogo in enakomerno zategnite cev in črpalko z vijaki, maticami in vzmetnimi podložkami.
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. Če med postopkom črpanja odkrijete pojav zagozditve, obrnite ali povlecite cev za vodo, da premagate točko zagozdenja. Če različni ukrepi še vedno ne delujejo, vas prosimo, da črpalke ne spustite na silo, da preprečite poškodbe potopne električne črpalke in vodnjaka.
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.

1. 1.After the submersible pump is installed, check the insulation resistance and three-phase conduction from the switch again, check whether the instrument and the connection of the start equipment are wrong, if there is no problem, the trial machine can be started, and after the start, observe whether the indicator readings of the instrument exceed the rated voltage and current specified on the nameplate, observe whether the pump has noise and vibration phenomenon, and put into operation if everything is normal.
