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

It taheakke prosesdiagram foar kabelbedrading is as folget:

8. Brûk in multimeter om te kontrolearjen oft de trije-fase triedden binne ferbûn en oft de DC ferset is likernôch lykwichtich.
9. Kontrolearje oft it circuit en transformator kapasiteit binne oerladen, en dan ferbinen de oerlêst beskerming switch of begjinnende apparatuer. Sjoch Tabel 2 foar spesifike modellen, en dan Giet in amer mei wetter yn 'e wetterpomp út' e wetterpompútlaat om de rubberlagers yn 'e pomp te smeerjen, en set dan de ûnderdompelbere elektryske pomp rjochtop en steady.Start (net mear as ien sekonde) en kontrolearje oft de stjoerrjochting oerienkomt mei it stjoerteken. As net, ruilje alle twa Anschlüsse fan 'e trije-faze kabel. Ynstallearje dan it filter en meitsje jo klear om de put del te gean. As brûkt by spesjale gelegenheden (lykas sleatten, sleatten, rivieren, fivers, fivers, ensfh.), De elektryske pomp moat betrouber wurde grûn.

(2) Ynstallaasje apparatuer en ark:
1. Ien pear liftkeatlingen foar mear as twa ton.
2. In tripod mei in fertikale hichte fan net minder as fjouwer meter.
3. Twa hingjende touwen (wire touwen) dy't in gewicht fan mear as ien ton drage kinne (kinne it gewicht fan in folsleine set wetterpompen drage).
4. Ynstallearje twa pearen fan clamps (spalken).
5. Wrenches, hammers, schroevendraaiers, elektryske ark en ynstruminten, ensfh.

(3) Elektryske pomp ynstallaasje:
1. It ynstallaasjediagram fan 'e ûnderdompele elektryske pomp wurdt werjûn yn figuer 2. De spesifike ynstallaasjedimensjes wurde werjûn yn Tabel 3 "List fan ynstallaasje-ôfmjittings fan 'e ûnderdompele elektryske pomp".

2. Submersible elektryske pompen mei in kop minder as 30 meter kinne direkt yn 'e boarne ophelle wurde mei slangen en draadseilen of oare himp-touwen dy't it folsleine gewicht fan' e hiele masine, wetterpipes, en wetter yn 'e pipes drage kinne.

3. Pompen mei in kop fan mear as 30 meter brûke stielen pipen, en de ynstallaasje folchoarder is as folget:
①Gebrûk in klem om it boppeste ein fan it wetterpompdiel te klemmen (de motor en de wetterpomp binne op dit stuit ferbûn), til it mei in hingjende keatling op en bine it stadichoan yn 'e put oant Set de klem op' e putkop en fuortsmite hingjende ketting.
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. （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. （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 the motor to burn out due to excessive current.
4. （4）After the pump is put into normal operation, in order to prolong its service life, it is necessary to check regularly whether the supply voltage, running current and insulation resistance are normal.If the following conditions are found, the pump should be shut down immediately to eliminate the fault:
5. 1 under the rated working conditions, the current exceeds 20%;
6. 2 the dynamic water level drops to the water inlet part, resulting in intermittent drainage;
7. 3 the submersible pump vibrates seriously or emits huge noise;
8. 4 the supply voltage is lower than 340 volts;
9. 5 a fuse is blown out;
10. 6 the water pipe is damaged;
11. 7 the thermal insulation resistance between the motor and the ground is less than 0.5 megaohm. The discovery of these problems need to be handled in time to ensure the normal operation of the pump, improve its reliability, so as to ensure the stable operation of the equipment for a long time.

（5）unit disassembly:

 1 untie the cable tie, remove the pipeline part, remove the wire plate.

 2 skroef de wetterbout del, set it wetter yn 'e motorkeamer.

 3 remove the filter, loose the fixing screw on the coupling to fix the motor shaft.

 4 screw down the bolt connecting the water inlet section with the motor, separate the pump and the motor (pay attention to the unit cushion when separating, prevent the bending of the pump shaft)

 5 pump disassembly sequence is: (see figure 1) water inlet section, impeller, diversion shell, impeller...... check valve body, when removing the impeller, use special tools to loosen the conical sleeve of the fixed impeller first, avoid bending the pump shaft and each part in the disassembly process.

 6 motor disassembly process is: (see figure 1) place the motor on the platform, and remove the nut, base, shaft head lock nut, thrust plate, key, lower guide bearing seat, double head bolt from the bottom of the motor in turn. Then take out the rotor (pay attention not to damage the wire package) and finally remove the connecting section and the upper guide bearing seat.

 7 unit assembly: Before assembly, the rust and dirt of the parts should be cleaned, and the mating surfaces and fasteners should be coated with sealant. Then they should be assembled in the reverse order of disassembly (the up and down momentum of the motor shaft is about 1 mm after assembly). After assembly, the coupling should be flexible, and then the filter screen test machine.

6. The submersible pump should be dismantled and repaired according to Article 5 for each operation year, or less than one year, but the submersible time has reached two years, and the worn parts should 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, store in an indoor room without corrosive substances and gases, with a temperature below 40 °C.

 3, lange-termyn gebrûk moatte betelje omtinken foar de roest previnsje fan dompelpompen.
