② Brûk in oar pear klemmen om in piip te klemmen, til it mei in hingjende ketting 15 sm fuort fan 'e flange, en ferleegje it stadich. Tusken pipe flange en pomp flangePut de rubberen pad yn plak en strak de piip en pomp gelyk mei bouten, moeren en spring washers.
③ Til de dompelpomp in bytsje op, ferwiderje de klem op 'e boppeste ein fan' e wetterpomp, bine de kabel stevich oan 'e wetterpipe mei in plestik tape, en bûgje it stadichoan oant De klem wurdt pleatst by de putkop.
④Brûk deselde metoade om alle wetterpipes yn 'e put te binen.
⑤ Neidat de lead-out kabel is ferbûn mei de kontrôle switch, it is ferbûn oan de trije-fase Netzteil.
(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.
- 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. After the pump is shut down, it should be started after five minutes to prevent the water column in the pipe from burning due to excessive motor current.
- 4. After the pump is running normally, in order to prolong its service life, it is necessary to check whether the power supply voltage, running current and insulation resistance are normal on a regular basis.If the following conditions are found, the equipment should be shut down immediately to eliminate the fault:
- - Under the rated working conditions, the current exceeds 20%.
- - The dynamic water level drops to the inlet section, resulting in intermittent drainage.
- - The submersible pump vibrates violently or emits noisy sounds.
- - The power supply voltage is lower than 340 volts.
- - There is a phase blown out in the fuse.
- - The water pipe is damaged.
- - The thermal insulation resistance between the motor and the ground is less than 0.5 megaohm.
- 5. Disassembly device:
- - Untie the cable, take off the pipe part and remove the line protection plate.
- - Unscrew the drain screw and exclude all water in the motor chamber.
- - Take out the filter and loosen the fixing screw on the coupling fixed to the motor shaft.
- - Unscrew the bolt connecting the water inlet section and the motor, and separate the pump and the motor (pay attention to the level of the device to prevent the bending of the pump shaft when separating).
- - The disassembly sequence of the pump is as follows: (see Figure 1) water inlet section, impeller, shunt shell, impeller, check valve body. When removing the impeller, use special tools to loosen the cone sleeve fixed to the impeller. In the process of disassembly, avoid bending the pump shaft and damaging various parts.
- - The disassembly process of the motor is as follows: (see Figure 1) place the motor on the platform, and remove the nuts, base, shaft head lock nut, thrust plate, key, lower guide bearing. seat, and tie rod bolts from the bottom of the motor in order (see Figure 1), and then take out the rotor (be careful not to damage the wiring harness) and finally take out the connector and upper guide bearing seat.
- - Assembly unit: before assembly, all parts should be cleaned of rust and dirt, and smear sealant on all the surfaces and fasteners, and then assemble in the opposite order of disassembly (the movement of the motor shaft after assembly is about 1 mm). After assembly, the coupling should be flexible, and then wear the filter for machine test. Submersible pumps shall be taken out of the well for dismantling and maintenance according to Article 5 after a year of operation, or less than a year of operation but two years of diving time, and the worn parts shall be replaced.
1, set it wetter yn 'e motorholte (benammen yn' e winter om foar te kommen dat de motor befriest), en bine de kabel goed.
2, bewarje yn in binnenkeamer sûnder korrosive stoffen en gassen, mei in temperatuer ûnder 40 °C.
3, lange-termyn gebrûk moatte betelje omtinken foar de roest previnsje fan dompelpompen.
