1. Jedan par lanaca za podizanje više od dvije tone.
2. Stativ s okomitom visinom ne manjom od četiri metra.
3. Dva viseća užeta (žičana užad) koja mogu podnijeti težinu veću od jedne tone (mogu podnijeti težinu kompletnog seta pumpi za vodu).
4. Ugradite dva para stezaljki (udlaga).
5. Ključevi, čekići, odvijači, električni alati i instrumenti itd.

(3) Instalacija električne pumpe:
1. Dijagram ugradnje potopne električne crpke prikazan je na slici 2. Specifične ugradbene dimenzije prikazane su u tablici 3 "Popis ugradbenih dimenzija potopne električne pumpe".

2. Potopne električne pumpe s visinom manjom od 30 metara mogu se podići izravno u bunar pomoću crijeva i žičane užadi ili druge užadi od konoplje koja može podnijeti punu težinu cijelog stroja, cijevi za vodu i vode u cijevima.

3. Crpke s visinom većom od 30 metara koriste čelične cijevi, a redoslijed ugradnje je sljedeći:
①Upotrijebite stezaljku za stezanje gornjeg kraja dijela pumpe za vodu (motor i pumpa za vodu su trenutno spojeni), podignite ga lancem za vješanje i polako ga zavežite u bunar dok ne postavite stezaljku na glavu bunara i uklonite viseći lanac.

⑤ Nakon što je izlazni kabel spojen na upravljačku sklopku, spaja se na trofazno napajanje.

(4) Stvari koje treba imati na umu tijekom instalacije:
1. Ako se tijekom procesa pumpanja otkrije pojava začepljenja, okrenite ili povucite cijev za vodu kako biste prevladali točku začepljenja. Ako razne mjere i dalje ne rade, nemojte silom spuštati pumpu kako biste izbjegli oštećenje potopne električne pumpe i bunara.
2. Tijekom instalacije, gumeni jastučić treba postaviti na prirubnicu svake cijevi i ravnomjerno ga 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 uz zid bunara, uzrokujući vibriranje pumpe, a motor brisanje i paljenje .
4. Odredite dubinu pumpe za vodu do dna bušotine prema uvjetima protoka pijeska i mulja u bušotini. Ne zakopavajte 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 smije biti manja od 1-1,5 metara od dinamičke razine vode do čvora za dovod vode (vidi sliku 2). Inače se ležajevi vodene pumpe mogu lako oštetiti.
6. Podizanje vodene pumpe ne smije biti prenisko. U suprotnom, na cjevovod za vodu na ušću bušotine potrebno je instalirati zasunski ventil za kontrolu protoka crpke na nazivnoj točki protoka kako bi se spriječilo preopterećenje motora i njegovo sagorijevanje zbog velikih protoka.
7. Kada pumpa za vodu radi, izlaz vode treba biti kontinuiran i ravnomjeran, struja bi trebala biti stabilna (pod nazivnim radnim uvjetima, općenito ne više od 10% nazivne struje), i ne bi trebalo biti vibracija ili buke. Ako postoji bilo kakva nepravilnost, stroj treba zaustaviti kako bi se otkrio uzrok i otklonio ga.
8. Prilikom postavljanja obratite pozornost na postavku žice za uzemljenje motora (vidi sliku 2). Kada je cijev za vodu čelična cijev, vodite je od stezaljke na ušću bušotine; kada je cijev za vodu plastična, vodite je od oznake za uzemljenje električne pumpe.

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 observe whether the indicator readings of the instrument exceed the rated voltage and current specified on the nameplate after the start, and observe whether the pump has noise and vibration phenomenon, and put into operation if everything is normal.
2. (2)After the first operation of the pump for four hours, the motor should be shut down to test the thermal insulation resistance quickly, and its value should not be less than 0.5 megaohm.
3. (3)After the pump is shut down, it should be started after five minutes to prevent the water column in the pipe from being completely reflowed and causing excessive motor current and burnout.
4. (4)After the pump is put into normal operation, in order to prolong its service life, it is necessary to check whether the supply voltage, working current and insulation resistance are normal regularly. If the following conditions are found, the pump should be shut down immediately to troubleshoot.

1 In the rated condition, the current exceeds 20%.

 2 Dinamička razina vode pada do dijela za dovod vode, uzrokujući povremenu vodu.

6. (5)Unit disassembly:

 1 Untie the cable tie, remove the pipeline part, and remove the wire plate.

 2 zavrnite vijak za vodu, stavite vodu u komoru motora.

 3 uklonite filtar, olabavite fiksni vijak na spojnici kako biste učvrstili osovinu motora.

 4 zavrnite vijak koji spaja dio za dovod vode s motorom i odvojite pumpu od motora (obratite pozornost na jastuk jedinice prilikom odvajanja kako biste spriječili savijanje osovine pumpe)

 5 redoslijed rastavljanja crpke je: (pogledajte sliku 1) dio za dovod vode, rotor, skretna školjka, rotor...... kućište nepovratnog ventila, prilikom uklanjanja rotora, koristite posebne alate za otpuštanje stožaste čahure fiksnog rotor i izbjegavajte savijanje i nagnječenje osovine pumpe tijekom procesa rastavljanja.

 6 postupak rastavljanja motora je: (pogledajte sliku 1) postavite motor na platformu i uklonite matice, bazu, sigurnosnu maticu glave vratila, potisnu ploču, ključ, donje ležište ležaja vodilice i vijak s dvostrukom glavom s dna motor zauzvrat, a zatim izvadite rotor (pazite da ne oštetite paket žice) i na kraju uklonite spojni dio i gornje ležište vodilice.

 7 montaža jedinice: prije montaže potrebno je očistiti hrđu i prljavštinu dijelova, a spojnu površinu i pričvršćivače premazati brtvilom, a zatim sastaviti redoslijedom obrnutim od rastavljanja (osovina motora se pomiče gore-dolje nakon montaže otprilike jedan milimetar), nakon sastavljanja, spojka bi trebala biti fleksibilna, a zatim stroj za ispitivanje sita filtera. Potopne pumpe treba izvaditi iz bušotine radi rastavljanja i održavanja u skladu s člankom 5. nakon godinu dana rada, ili manje od godinu dana rada, ali dvije godine ronjenja, a istrošeni dijelovi moraju se zamijeniti.

In order to ensure long-term use of your submersible pump, we strongly recommend that you drain the water in all motor cavities especially in winter to prevent the motor from freezing; at the same time, roll up the cable and tie it well. Store the equipment in a room without corrosive substances and gases, with the temperature below 40 °C. In addition, if you do not use the submersible pump for a long time, be sure to pay attention to rust prevention measures. These simple steps will help you maintain the performance of the equipment and extend its service life.
