6. Suv vintini bo'shating va vosita bo'shlig'ini toza, korroziy bo'lmagan suv bilan to'ldiring (eslatma. uni to'ldirishni unutmang), so'ngra suv vintini torting. 12 soatlik suv quyishdan so'ng, 500V chayqash stoli bilan o'lchanganda, dvigatelning izolyatsiyaga chidamliligi 150M Q dan kam bo'lmasligi kerak.
7. Cable joint, cut off a 120mm rubber sleeve from one end of the outgoing cable and the matching cable with an electrician's knifethen stagger the length of the three core wires in a stepped shape, peel off a 20mm copper core, scrape of the oxide layer on theoutside of the copper wire with a knife or sand cloth, and insert the two connected wire ends in palirs.After tying the layer tightly with fine copper wire, solder it thoroughly and firmly, and sand of any. burrs on the surface. 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

Qo'shilgan kabelni ulash jarayoni diagrammasi quyidagicha:

Muayyan modellar uchun 2-jadvalga qarang, so'ngra nasosdagi rezina podshipniklarni moylash uchun suv nasosining chiqishidan suv nasosiga bir chelak suv quying, so'ngra suv ostidagi elektr nasosni tik va barqaror joylashtiring. Ishga tushirish (bir soniyadan oshmasligi kerak) va rul yo'nalishi rul belgisiga mos kelishini tekshiring. Agar yo'q bo'lsa, uch fazali kabelning har qanday ikkita ulagichini almashtiring.Keyin filtrni o'rnating va quduqqa tushishga tayyorlang. Maxsus holatlarda (masalan, ariqlar, ariqlar, daryolar, suv havzalari, suv havzalari va boshqalar) ishlatilsa, elektr nasos ishonchli tarzda erga ulangan bo'lishi kerak.

5. Kalitlar, bolg'alar, tornavidalar, elektr asboblari va asboblari va boshqalar.

(3) Elektr nasosni o'rnatish:
1. Suv osti elektr nasosining o'rnatish sxemasi 2-rasmda ko'rsatilgan. Maxsus o'rnatish o'lchamlari 3-jadvalda "Suv ​​ostidagi elektr nasosni o'rnatish o'lchamlari ro'yxati" da ko'rsatilgan.

2. Boshi 30 metrdan kam bo'lgan suv osti elektr nasoslari to'g'ridan-to'g'ri quduqqa shlanglar va sim arqonlar yoki butun mashinaning, suv quvurlarining va quvurlardagi suvning to'liq og'irligini ko'tara oladigan boshqa kanop arqonlari yordamida ko'tarilishi mumkin.

3. Boshi 30 metrdan ortiq bo‘lgan nasoslar po‘lat quvurlardan foydalanadi va o‘rnatish ketma-ketligi quyidagicha:
①Suv nasos qismining yuqori uchini qisqich bilan mahkamlang (motor va suv nasosi bu vaqtda ulangan), uni osilgan zanjir bilan ko'taring va quduq boshiga qisqichni o'rnatguncha sekin quduqqa bog'lab qo'ying va osilgan zanjir.
② Quvurni mahkamlash uchun yana bir juft qisqichdan foydalaning, uni osilgan zanjir bilan gardishdan 15 sm uzoqlikda ko'taring va sekin pastga tushiring. Quvur gardish va nasos gardishi o'rtasida Kauchuk yostiqni joyiga qo'ying va quvurni torting va murvat, yong'oq va prujinali rondelalar bilan bir tekisda pompalang.
③ Suv osti nasosini biroz ko'taring, suv nasosining yuqori uchidagi qisqichni echib oling, kabelni suv trubasiga plastik lenta bilan mahkam bog'lang va qisqich quduq boshiga o'rnatilguncha sekin bog'lang.
④Hamma suv quvurlarini quduqqa ulash uchun xuddi shu usuldan foydalaning.
⑤Chiqish kabeli boshqaruv kalitiga ulangandan so'ng, u uch fazali quvvat manbaiga ulanadi.

(4) O'rnatish vaqtida e'tiborga olish kerak bo'lgan narsalar:
1. Nasos jarayonida tiqilib qolish hodisasi aniqlansa, tiqilib qolish nuqtasini yengish uchun suv trubkasini burang yoki torting. Agar turli xil choralar hali ham ishlamasa, iltimos, suv osti elektr nasosi va quduqqa shikast etkazmaslik uchun nasosni majburlamang.
2. O'rnatish vaqtida har bir quvurning gardish qismida kauchuk yostiq qo'yilishi va bir tekis tortilishi kerak.
3. Suv nasosi quduqqa tushirilganda, nasosning quduq devoriga uzoq vaqt davomida ishlamasligi, nasosning tebranishi va dvigatelning supurib yonishiga olib kelishi uchun uni quduq trubasining o'rtasiga qo'yish kerak. .
4. Quduqning oqayotgan qum va loy sharoitiga qarab suv nasosining quduq tubiga chuqurligini aniqlang. Nasosni loyga ko'mmang. Suv nasosidan quduq tubigacha bo'lgan masofa odatda 3 metrdan kam emas (2-rasmga qarang).
5. Suv nasosining suvga kirish chuqurligi dinamik suv sathidan suv kirish tuguniga qadar 1-1,5 metrdan kam bo'lmasligi kerak (2-rasmga qarang). Aks holda, suv nasosining podshipniklari osongina shikastlanishi mumkin.
6. Suv nasosining ko'tarilishi juda past bo'lishi mumkin emas. Aks holda, katta oqim tezligi tufayli dvigatelning haddan tashqari yuklanishi va yonib ketishining oldini olish uchun nominal oqim nuqtasida nasos oqimini nazorat qilish uchun quduq bo'yidagi suv quvur liniyasiga eshik klapanini o'rnatish kerak.
7. Suv pompasi ishlayotganida, suv chiqishi uzluksiz va bir tekis bo'lishi kerak, oqim barqaror bo'lishi kerak (nominal ish sharoitida, odatda nominal oqimning 10% dan ko'p bo'lmagan) va tebranish yoki shovqin bo'lmasligi kerak. Agar biron bir anormallik bo'lsa, sababni aniqlash va uni bartaraf etish uchun mashinani to'xtatish kerak.
8. O'rnatishda vosita topraklama simini sozlashga e'tibor bering (2-rasmga qarang). Suv trubkasi po'lat quvur bo'lsa, uni quduqning qisqichidan olib boring; suv trubkasi plastik quvur bo'lsa, uni elektr nasosning topraklama belgisidan olib boring.
