(1) Voorbereiding voor installasie:
1. Kontroleer of die dompelpomp voldoen aan die gebruiksvoorwaardes en omvang gespesifiseer in die handleiding.
2. Gebruik 'n swaar voorwerp met 'n deursnee gelyk aan die maksimum buitenste deursnee van die dompelpomp, meet of die binnedeursnee van die boorput by die dompelpomp kan pas, en meet of die putdiepte aan die installasievereistes voldoen.
3. Kontroleer of die boorput skoon is en of die putwater troebel is. Moet nooit 'n dompelpomp gebruik om die welor pomp modder en sand water te was om voortydige skade aan die dompel elektriese pomp te vermy.
4. Kontroleer of die posisie van die putkopinstallasieklem geskik is en of dit die kwaliteit van die hele eenheid kan weerstaan
5. Kontroleer of die dompelpompkomponente volledig en behoorlik geïnstalleer is volgens die samestellingsdiagram in die handleiding Verwyder die filterskerm en draai die koppeling om te sien of dit buigsaam draai
6. Skroef die waterskroef los en vul die motorholte met skoon, nie-korrosiewe water (let wel. maak seker dat jy dit vol maak), draai dan die waterskroef vas. Na 12 uur se waterinspuiting moet die isolasieweerstand van die motor nie minder as 150M Q wees as dit gemeet word met 'n 500V skudtafel nie.
7. Kabelverbinding, sny 'n 120mm rubberhuls van die een kant van die uitgaande kabel af en die bypassende kabel met 'n elektrisiënmes skuif dan die lengte van die drie kerndrade in 'n getrapte vorm, trek 'n 20mm koperkern af, skraap van die oksied laag aan die buitekant van die koperdraad met 'n mes of sandlap, en steek die twee gekoppelde draadpunte in palirs in. Nadat jy die laag styf vasgemaak het met fyn koperdraad, soldeer dit deeglik en stewig, en skuur van enige. brame op die oppervlak. Gebruik dan polivester-isolasieband vir die drie lasse om hulle op 'n semi-gestapelde manier vir drie wasbakke toe te draai. Draai die twee punte van die wikkellaag styf toe met nyiondraad, en gebruik dan 'n semi-gestapelde metode om die band vir drie lae toe te draai. Draai die buitelaag toe met hoëdruk-isolasieband vir drie lae. Vou laastens die drie drade saam en draai dit herhaaldelik vir vyf lae met hoëdrukband toe. Elke laag moet styf vasgebind wees, en die tussenlaagvoege moet styf en vyf wees om te verhoed dat water die isolasie binnedring en beskadig. Nadat dit toegedraai is, week in water by kamertemperatuur van 20 'c vir 12 uur, en meet die isolasieweerstand met 'n skudtafel , wat nie minder as 100M Ω moet wees nie

Die aangehegte kabelbedradingsprosesdiagram is soos volg:

8. Gebruik 'n multimeter om te kyk of die driefase-drade verbind is en of die GS-weerstand ongeveer gebalanseerd is.
9. Kontroleer of die stroombaan en transformatorkapasiteit oorlaai is, en koppel dan die oorbelastingbeskermingskakelaar of aansittoerusting aan. Sien Tabel 2 vir spesifieke modelle, en Gooi dan 'n emmer water in die waterpomp vanaf die waterpompuitlaat om die rubberlaers in die pomp te smeer, en plaas dan die dompel elektriese pomp regop en bestendig.Begin (nie meer as een sekonde nie) en kyk of die stuurrigting ooreenstem met die stuurteken. Indien nie, ruil enige twee verbindings van die driefase-kabel om. Installeer dan die filter en maak gereed om in die put af te gaan. Indien dit in spesiale geleenthede gebruik word (soos slote, slote, riviere, damme, damme, ens.), moet die elektriese pomp betroubaar geaard wees.

(2) Installasie toerusting en gereedskap:
1. Een paar hyskettings vir meer as twee ton.
2. 'n Driepoot met 'n vertikale hoogte van nie minder nie as vier meter.
3. Twee hangtoue (draadtoue) wat 'n gewig van meer as een ton kan dra (kan die gewig van 'n volledige stel waterpompe dra).
4. Installeer twee pare klampe (spalke).
5. Sleutels, hamers, skroewedraaiers, elektriese gereedskap en instrumente, ens.

(3) Elektriese pompinstallasie:
1. Die installasiediagram van die dompel-elektriese pomp word in Figuur 2 getoon. Die spesifieke installasie-afmetings word in Tabel 3 "Lys van Installasie-afmetings van die dompel-elektriese pomp" getoon.

2. Dompelbare elektriese pompe met 'n hoogte van minder as 30 meter kan direk in die put gehys word deur gebruik te maak van slange en draadtoue of ander henneptoue wat die volle gewig van die hele masjien, waterpype en water in die pype kan dra.

3. Pompe met 'n hoogte van meer as 30 meter gebruik staalpype, en die installasievolgorde is soos volg:
①Gebruik 'n klem om die boonste punt van die waterpompdeel vas te klem (die motor en waterpomp is op hierdie tydstip gekoppel), lig dit met 'n hangketting en bind dit stadig in die put vas totdat Sit die klem op die putkop en verwyder die hang ketting.
② Gebruik nog 'n paar klampe om 'n pyp vas te klem, lig dit met 'n hangketting 15 cm weg van die flens af, en laat sak dit stadig. Tussen pypflens en pompflensSit die rubberkussing in plek en trek die pyp vas en pomp eweredig met boute, moere en veerringe.
③ Lig die dompelpomp effens op, verwyder die klem aan die boonste punt van die waterpomp, bind die kabel stewig aan die waterpyp vas met 'n plastiekband, en maak dit stadig vas totdat Die klem by die putkop geplaas is.
④Gebruik dieselfde metode om alle waterpype in die put vas te bind.
⑤ Nadat die uitloopkabel aan die beheerskakelaar gekoppel is, word dit aan die driefase-kragbron gekoppel.

(4) Dinge om op te let tydens installasie:
1. Indien 'n versteuringsverskynsel tydens die pompproses gevind word, draai of trek die waterpyp om die vassteekpunt te oorkom. As verskeie maatreëls steeds nie werk nie, moet asseblief nie die pomp af dwing om skade aan die dompelpomp en die put te voorkom nie.
2. Tydens installasie moet 'n rubberkussing by die flens van elke pyp geplaas word en eweredig vasgedraai word.
3. Wanneer die waterpomp in die put laat sak word, moet dit in die middel van die putpyp geplaas word om te verhoed dat die pomp vir 'n lang tyd teen die putwand loop, wat veroorsaak dat die pomp vibreer en die motor vee en brand .
4. Bepaal die diepte van die waterpomp tot by die bodem van die put volgens die vloeiende sand- en sliktoestande van die put. Moenie die pomp in die modder begrawe nie. Die afstand vanaf die waterpomp na die bodem van die put is oor die algemeen nie minder nie as 3 meter (sien Figuur 2).
5. Die watertoevoerdiepte van die waterpomp moet nie minder nie as 1-1,5 meter wees vanaf die dinamiese watervlak na die waterinlaatknooppunt (sien Figuur 2). Andersins kan die waterpomplaers maklik beskadig word.
6. Die hysbak van die waterpomp kan nie te laag wees nie. Andersins moet 'n hekklep op die putkopwaterpyplyn geïnstalleer word om die pompvloei by die aangewese vloeipunt te beheer om te verhoed dat die motor oorlaai en uitbrand as gevolg van groot vloeitempo's.
7. Wanneer die waterpomp aan die gang is, moet die wateruitset aaneenlopend en eweredig wees, die stroom moet stabiel wees (onder gegradeerde werksomstandighede, gewoonlik nie meer as 10% van die aangeslane stroom), en daar moet geen vibrasie of geraas wees nie. As daar enige abnormaliteit is, moet die masjien gestop word om die oorsaak uit te vind en dit uit te skakel.
8. Wanneer jy installeer, let op die instelling van die motor se aarddraad (sien Figuur 2). Wanneer die waterpyp 'n staalpyp is, lei dit uit die putkopklem; wanneer die waterpyp 'n plastiekpyp is, lei dit vanaf die aardmerk van die elektriese 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, and put into operation if everything is normal.
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.

1 In the rated condition, the current exceeds 20%.

 2 Die dinamiese watervlak daal na die waterinlaatgedeelte, wat onderbroke water veroorsaak.

 3 Die dompelpomp het erge vibrasie of geraas.

 4 Die toevoerspanning is laer as 340 volt.

 5 'n Sekering is uitgebrand.

 6 Die watertoevoerpyp is beskadig.

 7 The motor's thermal insulation resistance is lower than 0.5 megaohm.

6. (5)Unit disassembly:

 1 Untie the cable tie, remove the pipeline part, and remove the wire plate.

 2 skroef die waterbout af, sit die water in die motorkamer.

 3 verwyder die filter, los die vaste skroef op die koppeling los om die motoras vas te maak.

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

 5 the disassembly sequence of the pump 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, and avoid bending and bruising the pump shaft in the process of disassembly.

 6 die demontageproses van die motor is: (sien figuur 1) plaas die motor op die platform, en verwyder die moere, basis, askop-sluitmoer, stootplaat, sleutel, onderste gidslaer-sitplek en dubbelkopbout van die onderkant van die motor op sy beurt, en haal dan die rotor uit (let op om nie die draadpakket te beskadig nie) en verwyder laastens die verbindingsgedeelte en boonste gidslagersitplek.

 7 unit assembly: before assembly, the rust and dirt of the parts should be cleaned, and the mating surface and fasteners coated with sealant, and then assembled in the opposite order of disassembly (the motor shaft moves up and down after assembly for about one millimeter), after assembly, the coupling should be flexible, and then the filter screen test machine. 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.

In order to ensure long-term use of your submersible pump, we strongly recommend that you drain the water in all motor cavities especially in winter to prevent the motor from freezing; at the same time, roll up the cable and tie it well. Store the equipment in a room without corrosive substances and gases, with the temperature below 40 °C. In addition, if you do not use the submersible pump for a long time, be sure to pay attention to rust prevention measures. These simple steps will help you maintain the performance of the equipment and extend its service life.
