③ Tõstke sukelpumpa veidi üles, eemaldage veepumba ülemise otsa klamber, siduge kaabel plastlindiga kindlalt veetoru külge ja kinnitage see aeglaselt alla, kuni klamber asetatakse kaevupea külge.
④ Kasutage sama meetodit kõigi veetorude ühendamiseks kaevu.
⑤Pärast väljundkaabli ühendamist juhtlülitiga ühendatakse see kolmefaasilise toiteallikaga.
(4) Asjad, mida paigaldamise ajal tähele panna:
1. Kui pumpamise ajal avastatakse kinnikiilumine, keerake või tõmmake veetoru, et ummistuspunktist üle saada. Kui erinevad meetmed ikka ei tööta, ärge suruge pumpa jõuga alla, et vältida sukelduspumba ja kaevu kahjustamist.
2. Paigaldamise ajal tuleb iga toru ääriku juurde asetada kummist padi ja see ühtlaselt pingutada.
3. Kui veepump on langetatud kaevu, tuleb see asetada kaevu toru keskele, et pump ei töötaks pikka aega vastu kaevu seina, põhjustades pumba vibratsiooni ja mootori pühkima ja põlema. .
4. Määrake veepumba sügavus kaevu põhjani vastavalt kaevu voolava liiva ja muda tingimustele. Ärge matke pumpa muda sisse. Kaugus veepumbast kaevu põhjani ei ole üldjuhul väiksem kui 3 meetrit (vt joonis 2).
5. Veepumba vee sisenemise sügavus ei tohiks olla väiksem kui 1-1,5 meetrit dünaamilise veetasemest vee sisselaskesõlmeni (vt joonis 2). Vastasel juhul võivad veepumba laagrid kergesti kahjustada saada.
6. Veepumba tõstejõud ei tohi olla liiga madal. Vastasel juhul tuleb kaevupea veetorustikule paigaldada tõukeventiil, mis juhib pumba voolu nimivoolupunktis, et vältida mootori ülekoormamist ja läbipõlemist suurte vooluhulkade tõttu.
7. Kui veepump töötab, peab vee väljund olema pidev ja ühtlane, vool peab olema stabiilne (nimitöötingimustes, üldjuhul mitte rohkem kui 10% nimivoolust) ning ei tohiks olla vibratsiooni ega müra. Kui esineb kõrvalekaldeid, tuleb masin peatada, et põhjus välja selgitada ja see kõrvaldada.
8. Paigaldamisel pöörake tähelepanu mootori maandusjuhtme seadistusele (vt joonis 2). Kui veetoru on terastoru, viige see kaevupea klambrist; kui veetoru on plasttoru, juhtige see elektripumba maandusmärgist.
(1)submersible pump installation is complete, re-check the insulation resistance and three-phase conduction from the switch, check the instrument and start the equipment connection error, if there is no problem, can start the trial, after the start of the instrument indicating readings whether more than the nameplate stipulated rated voltage and current, observe the pump noise and vibration phenomenon, everything is normal can be put into operation.
(2)pump operation for the first four hours, should be shut down quickly test the thermal insulation resistance of the motor, the value should not be less than 0.5 megaohm.
(3)pump shutdown, should be started after an interval of five minutes, to prevent the water column in the pipe has not completely reflux caused by excessive motor current and burnout.

(5)This product is a portable water pump, with the characteristics of easy disassembly, the user can disassemble and clean the various components according to the following steps to maintain the normal operation of the pump. First of all to untie the cable tie, remove the pipeline part and take off the line protection plate. Then unscrew the drain bolt, discharge all the water in the motor chamber. Then take off the filter, loosen the fixing screw on the coupling fixed motor shaft. Then unscrew the bolt connecting the water inlet section and the motor, the pump and the motor separation (pay attention to the device leveling when separating, to prevent the bending of the pump shaft). The sequence of disassembly of the pump is: water inlet section, impeller, guide housing, impeller, check valve body. When disassembling the impeller, use special tools to loosen the cone sleeve fixed the impeller. In the whole disassembly process, pay attention to avoid bending the pump shaft and damage various parts. The steps of motor disassembly are: put the motor on the platform, remove the nut, seat, shaft head lock nut, thrust plate, key, lower guide rail from the bottom in order (tie rod bolt), then remove the rotor (pay attention not to damage the wire packet), and finally remove the connecting section and the upper guide bearing seat. Before assembly, the rust and dirt of each part should be cleaned, and sealant should be applied to each mating surface and fastener, and then the assembly should be carried out in the opposite order of disassembly (the movement of the motor shaft after assembly is about 1 mm). After assembly, the coupling should be flexible, and then the filter should be put on for machine test. 6. Submersible electric pump should be taken out of the well for dismantling and maintenance according to Article 5 after operating for one year, or less than one year, but the diving time has reached two years, and the worn parts should be replaced.
