3. Pumbad, mille kõrgus on üle 30 meetri, kasutavad terastorusid ja paigaldusjärjestus on järgmine:
① Kasutage klambrit, et kinnitada veepumba osa ülemine ots (mootor ja veepump on sel ajal ühendatud), tõstke see rippuva ketiga üles ja siduge aeglaselt kaevu, kuni pange klamber kaevupea külge ja eemaldage rippuv kett.
② Kasutage toru kinnitamiseks teist paari klambreid, tõstke see rippketiga äärikust 15 cm kaugusele ja langetage aeglaselt. Toruääriku ja pumba ääriku vahele Asetage kummipadi paika ning pingutage toru ja pump ühtlaselt poltide, mutrite ja vedruseibidega.
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.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. If everything is normal, it can be put into operation.
- 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. After the pump is shut down, it should be started after five minutes to prevent the water column in the pipe from burning due to excessive motor current.
- 4. After the pump is running normally, in order to prolong its service life, it is necessary to check whether the power supply voltage, running current and insulation resistance are normal on a regular basis.If the following conditions are found, the equipment should be shut down immediately to eliminate the fault:
- - Under the rated working conditions, the current exceeds 20%.
- - The dynamic water level drops to the inlet section, resulting in intermittent drainage.
- - The submersible pump vibrates violently or emits noisy sounds.
- - The power supply voltage is lower than 340 volts.
- - There is a phase blown out in the fuse.
- - The water pipe is damaged.
- - The thermal insulation resistance between the motor and the ground is less than 0.5 megaohm.
- 5. Disassembly device:
- - Untie the cable, take off the pipe part and remove the line protection plate.
- - Unscrew the drain screw and exclude all water in the motor chamber.
- - Take out the filter and loosen the fixing screw on the coupling fixed to the motor shaft.
- - Unscrew the bolt connecting the water inlet section and the motor, and separate the pump and the motor (pay attention to the level of the device to prevent the bending of the pump shaft when separating).
- - The disassembly sequence of the pump is as follows: (see Figure 1) water inlet section, impeller, shunt shell, impeller, check valve body. When removing the impeller, use special tools to loosen the cone sleeve fixed to the impeller. In the process of disassembly, avoid bending the pump shaft and damaging various parts.
- - The disassembly process of the motor is as follows: (see Figure 1) place the motor on the platform, and remove the nuts, base, shaft head lock nut, thrust plate, key, lower guide bearing. seat, and tie rod bolts from the bottom of the motor in order (see Figure 1), and then take out the rotor (be careful not to damage the wiring harness) and finally take out the connector and upper guide bearing seat.
- - Assembly unit: before assembly, all parts should be cleaned of rust and dirt, and smear sealant on all the surfaces and fasteners, and then assemble 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 wear the filter for machine test. Submersible pumps shall be taken out of the well for dismantling and maintenance according to Article 5 after a year of operation, or less than a year of operation but two years of diving time, and the worn parts shall be replaced.
1, kustutage vesi mootori õõnsusest (eriti talvel, et mootor ei külmuks) ja ühendage kaabel hästi.
2, store in an indoor room without corrosive substances and gases, with a temperature below 40 °C.
3, pikaajaline kasutamine peaks pöörama tähelepanu sukelpumpade roostetõrjele.
