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.
② Upotrijebite drugi par stezaljki za stezanje cijevi, podignite je visećim lancem 15 cm od prirubnice i polako je spustite. Između prirubnice cijevi i prirubnice pumpe Stavite gumenu podlogu na mjesto i ravnomjerno zategnite cijev i pumpu vijcima, maticama i opružnim podloškama.
③ Lagano podignite potopnu pumpu, uklonite stezaljku na gornjem kraju pumpe za vodu, čvrsto zavežite kabel za cijev za vodu plastičnom trakom i polako je pričvrstite dok se stezaljka ne postavi na ušće bunara.
④Upotrijebite istu metodu za vezivanje svih cijevi za vodu u bunar.
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.

 After the installation of the underwater pump, the insulation resistance and three-phase continuity of the switch face should be rechecked, and the connection between the instrument and the start device should be checked for any errors. If there is no problem, you can start to test the machine. After the start, observe whether the indication readings of each instrument are correct. If the rated voltage and current specified on the nameplate are exceeded, observe whether the pump has noise or vibration. If everything is normal, it can be put into operation. After the first operation of the pump for four hours, the motor should be shut down and tested for thermal insulation resistance quickly. Its value should not be less than 0.5 megaohm. After stopping the pump, it should be restarted after an interval of five minutes to prevent the water column in the pipeline from completely reversing and causing the motor to burn out due to excessive current. After the pump is put into normal operation, in order to prolong its service life, it is necessary to check regularly whether the supply voltage, running current and insulation resistance are normal. If the following conditions are found, the machine should be shut down immediately to eliminate the fault: the current exceeds 20% under rated working conditions; the dynamic water level drops to the inlet section, resulting in intermittent drainage; the underwater pump becomes violently vibrating or making noise; the supply voltage is lower than 340 volts; a fuse is blown out; the water pipe is damaged; the motor's thermal insulation resistance to the earth is less than 0.5 megaohm. The sequence of disassembly is: untie the cable fastening, remove the pipeline part, remove the line protection plate, screw down the water discharge bolt and discharge all the water in the motor chamber, remove the filter and loosen the coupling fixing screw of the motor shaft. The sequence of disassembly of the pump is: (see Figure 1) inlet section, impeller, guide housing, impeller, check the valve body. When removing the impeller, use special tools to loosen the taper sleeve of the impeller. Avoid bending the pump shaft and damaging the components throughout the process. The disassembly process of the motor is: (see Figure 1) put the motor on the platform, and remove the bolts, base, shaft head lock nut, thrust plate, key, lower guide plate (transverse bolt), bearing seat, screw knife seat from the bottom of the motor in order (take care not to damage the winding), and finally remove the connecting part and the upper guide bearing seat. Before assembling the unit, the rust and dirt of each part should be cleaned, and the sealant should be applied to each mating surface and fastener, and then assembled in reverse order of disassembly (the movement of the motor shaft after assembly is about one millimeter). After assembly, the coupling should be rotated flexibly and put on the filter for test. Once a year, or if less than a year of operation but has been immersed for two years, the underwater electric pump must be disassembled for maintenance in accordance with Article 5 and replace worn parts to ensure the normal operation and durability of the pump.

 1, ispustite vodu iz šupljine motora (posebno zimi kako biste spriječili smrzavanje motora) i dobro zavežite kabel.

 2, store in an indoor room without corrosive substances and gases, with a temperature below 40 °C.

 3, dugotrajna uporaba treba obratiti pozornost na prevenciju hrđe potopnih pumpi.
