Then, forthe three joints, use polyvester insulation tape to wrap them in a semi stacked manner for three lavers. Wrap the two ends of thewrapping layer tightywith nyion thread,and then use a semi stacked method to wrap the tape for three layers. Wrap the outellayer with high-pressure insulation tape for three layers. Finally, fold the threestrands together and repeatedly wrap them for fivelayers with high-pressure tape. Each layer must be tightly tied, and the interlayer joints must be tight and fimm to prevent water frompenetrating and damaging the insulation, After wrapping, soak in water at room temperature of 20 ’c for 12 hours, and measurethe insulation resistance with a shaking table, which should not be less than 100M Ω

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.
