Dyagram pwosesis fil elektrik kab atache a se jan sa a:

8. Sèvi ak yon miltimèt pou tcheke si wi ou non fil twa-faz yo konekte epi si rezistans DC a apeprè ekilibre.
9. Tcheke si sikwi a ak kapasite transfòmatè yo twò chaje, ak Lè sa a, konekte switch la pwoteksyon surcharge oswa ekipman kòmanse. Gade Tablo 2 pou modèl espesifik, ak Lè sa a, Vide yon bokit dlo nan ponp dlo a soti nan priz ponp dlo a wile BEARINGS kawotchou yo nan ponp lan, ak Lè sa a, mete ponp lan submersible elektrik dwat ak fiks. Kòmanse (pa plis pase yon segonn) epi tcheke si direksyon volan an konsistan avèk siy volan an. Si ou pa, chanje nenpòt ki de konektè nan twa-faz kab la. Lè sa a, enstale filtè a epi prepare yo desann pi a. Si yo itilize nan okazyon espesyal (tankou twou, twou, rivyè, etan, etan, elatriye), ponp elektrik la dwe fyab sou tè.

(2) Enstalasyon ekipman ak zouti:
1. Yon pè chenn leve pou plis pase de tòn.
2. Yon trépied ak yon wotè vètikal pa mwens pase kat mèt.
3. De kòd pandye (kòd fil) ki ka pote yon pwa ki gen plis pase yon tòn (ka pote pwa a nan yon seri konplè ponp dlo).
4. Enstale de pè kranpon (atèl).
5. Kle, mato, tournevis, zouti elektrik ak enstriman, elatriye.

(3) Enstalasyon ponp elektrik:
1. Dyagram enstalasyon ponp elektrik submersible a montre nan Figi 2. Dimansyon enstalasyon espesifik yo montre nan Tablo 3 "Lis Dimansyon Enstalasyon ponp elektrik Submersible a".

2. Ponp elektrik submersible ak yon tèt mwens pase 30 mèt ka leve dirèkteman nan pi a lè l sèvi avèk kawotchou ak kòd fil oswa lòt kòd chanv ki ka pote pwa a plen nan machin nan tout antye, tiyo dlo, ak dlo nan tiyo yo.

3. Ponp ak yon tèt ki gen plis pase 30 mèt itilize tiyo asye, ak sekans enstalasyon an se jan sa a:
①Sèvi ak yon kranpon pou sere pwent anwo nan pati ponp dlo a (motè a ak ponp dlo yo te konekte nan moman sa a), leve l ak yon chèn pandye, epi tou dousman mare l nan pi a jiskaske Mete kranpon an sou tèt pi a epi retire li. pandye chèn.
② Sèvi ak yon lòt pè kranpon pou sere yon tiyo, leve l ak yon chenn pandye 15 cm lwen bride a, epi bese l tou dousman. Ant bride tiyo ak bride ponp Mete pad kawotchou a an plas epi sere boulon tiyo a ak ponpe respire ak boulon, nwa ak rondelles prentan.
③ Leve ponp submersible a yon ti kras, retire kranpon an sou pwent anwo ponp dlo a, mare kab la byen fèm nan tiyo dlo a ak yon kasèt plastik, epi tou dousman mare li desann jiskaske kranpon an mete nan tèt pi a.
④Sèvi ak menm metòd pou mare tout tiyo dlo nan pi a.
⑤Apre kab plon an konekte ak switch kontwòl la, li konekte ak ekipman pou pouvwa twa faz la.

(4) Bagay ou dwe sonje pandan enstalasyon:
1. Si yo jwenn yon fenomèn blokis pandan pwosesis ponp lan, vire oswa rale tiyo dlo a simonte pwen an blocage. Si plizyè mezi toujou pa travay, tanpri pa fòse ponp lan desann pou evite domaj nan ponp elektrik submersible ak pi a.
2. Pandan enstalasyon, yo ta dwe mete yon pad kawotchou nan bride chak tiyo epi sere boulon respire.
3. Lè ponp dlo a bese nan pi a, li ta dwe mete l nan mitan tiyo a pou anpeche ponp lan kouri kont miray la byen pou yon tan long, sa ki lakòz ponp lan vibre ak motè a bale ak boule. .
4. Detèmine pwofondè ponp dlo a nan fon pi a dapre sab koule ak kondisyon limon nan pi a. Pa antere ponp lan nan labou. Distans ki soti nan ponp dlo a nan anba a nan pi a se jeneralman pa mwens pase 3 mèt (gade Figi 2).
5. Pwofondè dlo a antre nan ponp dlo a ta dwe pa mwens pase 1-1.5 mèt soti nan nivo dlo dinamik nan ne inlet dlo a (gade Figi 2). Sinon, bi ponp dlo yo ka fasil domaje.
6. Leve ponp dlo a pa ka twò ba. Sinon, yon tiyo pòtay bezwen yo dwe enstale sou tiyo dlo a pou kontwole koule ponp lan nan pwen an koule rated pou anpeche motè a twò chaje ak boule akòz gwo pousantaj koule.
7. Lè ponp dlo a ap kouri, pwodiksyon dlo a ta dwe kontinyèl e menm, aktyèl la ta dwe estab (anba kondisyon travay rated, jeneralman pa plis pase 10% aktyèl la nominal), epi pa ta dwe gen okenn vibrasyon oswa bri. Si gen nenpòt anòmal, yo ta dwe sispann machin nan pou chèche konnen kòz la epi elimine li.
8. Lè w ap enstale, peye atansyon sou anviwònman fil motè a (gade Figi 2). Lè tiyo dlo a se yon tiyo asye, mennen li soti nan kranpon nan wellhead; lè tiyo dlo a se yon tiyo plastik, mennen li soti nan mak baz la nan ponp elektrik la.

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 being completely reflowed and causing the motor to burn out due to excessive current.
4. （4）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 pump should be shut down immediately to eliminate the fault:
5. 1 under the rated working conditions, the current exceeds 20%;
6. 2 the dynamic water level drops to the water inlet part, resulting in intermittent drainage;
7. 3 the submersible pump vibrates seriously or emits huge noise;
8. 4 the supply voltage is lower than 340 volts;
9. 5 a fuse is blown out;
10. 6 the water pipe is damaged;
11. 7 the thermal insulation resistance between the motor and the ground is less than 0.5 megaohm. The discovery of these problems need to be handled in time to ensure the normal operation of the pump, improve its reliability, so as to ensure the stable operation of the equipment for a long time.

（5）unit disassembly:

 1 untie the cable tie, remove the pipeline part, remove the wire plate.

 2 vis desann boulon dlo a, mete dlo a nan chanm motè a.

 3 remove the filter, loose the fixing screw on the coupling to fix the motor shaft.

 4 screw down the bolt connecting the water inlet section with the motor, separate the pump and the motor (pay attention to the unit cushion when separating, prevent the bending of the pump shaft)

 5 pump disassembly sequence 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, avoid bending the pump shaft and each part in the disassembly process.

 6 motor disassembly process 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 the 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.

6. 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, mete dlo a nan kavite motè a (sitou nan sezon fredi pou anpeche motè a konjel), epi mare kab la byen.

 2, magazen nan yon chanm andedan kay la san sibstans korozif ak gaz, ak yon tanperati ki anba a 40 °C.

 3, itilizasyon alontèm yo ta dwe peye atansyon sou prevansyon rouye ponp submersible yo.
