(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）With the continuous development of modern technology, submersible pumps play a crucial role in the field of pumps. After installing the submersible pump, check the insulation resistance and three-phase continuity repeatedly to ensure that there are no errors in the connection between the instrument and the starting equipment. If everything is normal, the test equipment can be started. After starting, observe whether the indication readings of each instrument are correct. If the rated voltage and current specified on the nameplate are exceeded, pay attention to observe whether the pump has any noise or vibration. If everything is normal, it can be put into operation. After the pump runs for four hours for the first time, it should be closed and the thermal insulation resistance of the motor should be tested quickly, and its value should not be less than 0.5 megaohms. After stopping the pump, restart it after five minutes to prevent the water column in the pipeline from completely reversing, resulting in the motor burning due to overcurrent. After the pump is running normally, in order to prolong its service life, it is necessary to check regularly whether the supply voltage, working current and insulation resistance are normal. If the following conditions are found, the equipment should be shut down immediately to troubleshoot. The current exceeds 20% under the rated working conditions; the dynamic water level drops to the inlet section, resulting in intermittent drainage; the submersible pump vibrates violently or makes noisy sounds; the supply voltage is lower than 340 volts; any fuse is broken; the water pipe is damaged; The thermal insulation resistance between the motor and the ground is less than 0.5 megaohm.These recommended operating procedures and safety measures ensure the safe operation of the submersible pump, prolong the service life of the equipment, and provide users with a reliable pump choice.
•  
• （2）Unit disassembly:
• 1 untie the cable tie, remove the pipeline part, remove the wire plate.
• 2 unscrew the water release bolt, put the water in the motor chamber.
• 3 remove the filter, loose the fixing screw of the motor shaft on the coupling.
• 4 unscrew the bolt connecting the water inlet section with the motor, and separate the pump from the motor (pay attention to the unit cushion when separating, to prevent the bending of the pump shaft)
• 5 the disassembly sequence of the pump is: (see figure 1) water inlet section, impeller, diversion shell, impeller...... check valve body, when removing the impeller, use special tools to loosen the conical sleeve of the fixed impeller first, and avoid bending the pump shaft and various bumps in the disassembly process.
• 6 the disassembly process of the motor is: (see figure 1) place the motor on the platform, and remove the nut, base, shaft head lock nut, thrust plate, key, lower guide bearing seat, double head bolt from the bottom of the motor in turn. Then take out the rotor (pay attention not to damage the wire package) and finally remove the connecting section and upper guide bearing seat.
• 7 unit assembly: Before assembly, the rust and dirt of the parts should be cleaned, and the mating surfaces and fasteners should be coated with sealant. Then they should be assembled in the reverse order of disassembly (the up and down momentum of the motor shaft is about 1 mm after assembly). After assembly, the coupling should be flexible, and then the filter screen test machine.
•  
• （3）The submersible pump should be dismantled and repaired according to Article 5 for each operation year, or less than one year, but the submersible time has reached two years, and the worn parts should be replaced.

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

 2, čuvati u zatvorenoj prostoriji bez korozivnih tvari i plinova, s temperaturom ispod 40 °C.

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