(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.

1. (1)After installing the submersible pump, it is necessary to recheck the insulation resistance and three-phase continuity of the switch, and check whether there are errors in the connection between the instrument and the starting equipment. If there is no problem, the test machine can be started. After starting, observe whether the indication readings of the instruments exceed the rated voltage and current specified on the nameplate, and observe whether the pump has noise and vibration. 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 excessive motor current and burnout.
4. (4)After the pump is put into normal operation, in order to prolong its service life, it is necessary to check whether the supply voltage, working current and insulation resistance are normal regularly. If the following conditions are found, the pump should be shut down immediately to troubleshoot.
