(4) Dingen om op te merken by ynstallaasje:
1. As in jamming ferskynsel wurdt fûn tidens it pompen proses, draaie of lûke de wetter piip te oerwinnen it jamming punt. As ferskate maatregels noch net wurkje, twinge asjebleaft de pomp net omleech om skea oan 'e dompelpomp en de put te foarkommen.
2. By ynstallaasje moat in rubberen pad op 'e flange fan elke piip pleatst wurde en gelijkmatig oanskerpe.
3. As de wetterpomp yn 'e boarne ferlege wurdt, moat it yn' e midden fan 'e putpipe pleatst wurde om te foarkommen dat de pomp lang tsjin' e wellmuorre rint, wêrtroch't de pomp trillet en de motor sweep en brânt .
4. Bepale de djipte fan 'e wetterpomp nei de boaiem fan' e boarne neffens de streamende sân- en siltbetingsten fan 'e boarne. Begrave de pomp net yn 'e modder. De ôfstân fan 'e wetterpomp nei de boaiem fan' e put is oer it generaal net minder as 3 meter (sjoch figuer 2).
5. De wetteryngongsdjipte fan 'e wetterpomp moat net minder wêze as 1-1,5 meter fan it dynamyske wetterpeil nei it wetteryntreeknooppunt (sjoch figuer 2). Oars kinne de wetterpomplagers maklik skea wurde.
6. De lift fan 'e wetterpomp kin net te leech wêze. Oars, in poarte fentyl moat wurde ynstallearre op de wellhead wetter pipeline te kontrolearjen de pomp trochstreaming op de rated flow punt om foar te kommen dat de motor wurdt oerladen en útbaarnd fanwege grutte stream tariven.
7. As de wetterpomp rint, moat de wetterútfier kontinuële en sels wêze, de aktuele moat stabyl wêze (ûnder beoardielde wurkomstannichheden, oer it generaal net mear as 10% fan 'e nominearre aktuele), en der moat gjin trilling of lûd wêze. As der in abnormaliteit is, moat de masine wurde stoppe om de oarsaak te finen en it te eliminearjen.
8. By it ynstallearjen, betelje omtinken oan de ynstelling fan 'e motor grûndraad (sjoch figuer 2). As it wetter piip is in stielen piip, liedt it út de puthead clamp; as it wetter piip is in plestik piip, liedt it út 'e grûn mark fan' e elektryske pomp.

• 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.
