3. Rong tali gantung (tali kawat) sing bisa nanggung bobot luwih saka siji ton (bisa nanggung bobot saka set lengkap pompa banyu).
4. Pasang rong pasang clamps (splints).
5. Kunci pas, palu, obeng, piranti lan piranti listrik, lsp.

(3) Instalasi pompa listrik:
1. Diagram instalasi pompa listrik submersible ditampilake ing Gambar 2. Dimensi instalasi spesifik ditampilake ing Tabel 3 "Dhaptar Dimensi Instalasi Pompa Listrik Submersible".

2. Pompa listrik submersible kanthi sirah kurang saka 30 meter bisa diangkat langsung menyang sumur nggunakake selang lan tali kawat utawa tali rami liyane sing bisa nanggung bobot kabeh mesin, pipa banyu, lan banyu ing pipa.

3. Pumps kanthi sirah luwih saka 30 meter nggunakake pipa baja, lan urutan instalasi kaya ing ngisor iki:
①Gunakake penjepit kanggo ngapit ujung ndhuwur bagean pompa banyu (motor lan pompa banyu wis disambungake ing wektu iki), angkat nganggo rantai gantung, lan alon-alon dasi menyang sumur nganti pasang clamp ing sirah sumur lan copot ranté gantung.
② Gunakake sepasang klem liyane kanggo njepit pipa, angkat nganggo rante gantung 15 cm adoh saka flange, banjur mudhunake alon-alon. Antarane flange pipe lan flange pumpLebokake pad karet ing panggonan lan kenceng pipa lan pompa roto-roto nganggo bolts, perkakas lan spring washers.
③ Angkat pompa submersible rada, copot clamp ing mburi ndhuwur pump banyu, dasi kabel kuwat menyang pipa banyu karo plastik tape, lan alon dasi mudhun nganti Clamp diselehake ing wellhead.
④Gunakake cara sing padha kanggo naleni kabeh pipa banyu menyang sumur.
⑤Sawise kabel timbal-metu disambungake menyang saklar kontrol, disambungake menyang sumber daya telung fase.

(4) Bab sing kudu digatekake sajrone instalasi:
1. Yen ana fenomena jamming nalika proses pumping, nguripake utawa narik pipa banyu kanggo ngatasi titik jamming. Yen macem-macem langkah isih ora bisa, please Aja meksa kumpa mudhun kanggo ngindhari karusakan ing pompa listrik submersible lan sumur.
2. Sajrone instalasi, pad karet kudu diselehake ing flange saben pipa lan tightened roto-roto.
3. Nalika pompa banyu diturunake menyang sumur, kudu diselehake ing tengah pipa sumur supaya pompa ora mlaku ing tembok sumur nganti suwe, nyebabake pompa kedher lan motor nyapu lan diobong. .
4. Nemtokake ambane pompa banyu ing ngisor sumur miturut kondisi pasir lan lempung sing mili. Aja ngubur pompa ing lendhut. Jarak saka pompa banyu menyang dhasar sumur umume ora kurang saka 3 meter (pirsani Gambar 2).
5. Ambane entri banyu saka pompa banyu kudu ora kurang saka 1-1,5 meter saka tingkat banyu dinamis menyang simpul inlet banyu (pirsani Gambar 2). Yen ora, bantalan pompa banyu bisa gampang rusak.
6. Angkat pompa banyu ora bisa sithik banget. Yen ora, katup gapura kudu dipasang ing pipa banyu sumur kanggo ngontrol aliran pompa ing titik aliran sing dirating kanggo nyegah motor kakehan lan kobong amarga tingkat aliran gedhe.
7. Nalika pompa banyu mlaku, output banyu kudu terus-terusan lan malah, arus kudu stabil (ing kondisi kerja sing dirating, umume ora luwih saka 10% saka arus sing dirating), lan ora ana getaran utawa gangguan. Yen ana kelainan, mesin kudu mandheg kanggo ngerteni sababe lan ngilangi.
8. Nalika nginstal, mbayar manungsa waé menyang setelan saka kabel grounding motor (ndeleng Figure 2). Nalika pipa banyu minangka pipa baja, mimpin saka clamp wellhead; nalika pipa banyu minangka pipa plastik, mimpin saka tandha grounding pompa listrik.

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. If everything is normal, it can be put into operation.
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 burning due to excessive motor current.
4. 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:
5. - Under the rated working conditions, the current exceeds 20%.
6. - The dynamic water level drops to the inlet section, resulting in intermittent drainage.
7. - The submersible pump vibrates violently or emits noisy sounds.
8. - The power supply voltage is lower than 340 volts.
9. - There is a phase blown out in the fuse.
10. - The water pipe is damaged.
11. - The thermal insulation resistance between the motor and the ground is less than 0.5 megaohm.

1. 5. Disassembly device:
2. - Untie the cable, take off the pipe part and remove the line protection plate.
3. - Unscrew the drain screw and exclude all water in the motor chamber.
4. - Take out the filter and loosen the fixing screw on the coupling fixed to the motor shaft.
5. - 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).
6. - 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.
7. - 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.
8. - 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, sijine metu banyu ing growong motor (utamané ing mangsa kanggo nyegah motor saka pembekuan), lan dasi kabel uga.

 2, simpen ing kamar njero ruangan tanpa zat korosif lan gas, kanthi suhu ing ngisor 40 °C.

 3, nggunakake long-term kudu mbayar manungsa waé kanggo Nyegah teyeng saka pumps submersible.
