This well submersible pump is a pump suitable for clean water. Digging new wells and pumping sediment and turbid water are strictly prohibited. The voltage grade of the well pump is 380V/50HZ. Submersible motors with other voltage grades need to be customized. Underground cables must use waterproof cables and must be equipped with starting equipment, such as distribution boxes, etc. The starting equipment should have common comprehensive motor protection functions, such as overload short circuit protection, phase loss protection, undervoltage protection, grounding protection and idling protection, etc. In abnormal cases, the protection device should be tripped in time. During installation and use, the pump must be reliably grounded. It is prohibited to push and pull the switch when hands and feet are wet. The power supply must be cut off before installation and maintenance of the pump. The place where the pump is used must be set up with obvious "anti-electric shock" marks. Before going down the well or installation, the motor must be injected with distilled water or non-corrosive clear cold water in the inner cavity, and the intake/drain bolts must be tightened. When testing the pump on the ground, water must be injected into the pump chamber to lubricate the rubber bearings. The instant start time should not exceed one second to check whether the direction is correct. The same as the steering instructions. Pay attention to safety when the pump is upright to prevent tilting and injury. Strictly in accordance with the provisions of the pump lift and flow range, to prevent the pump flow at low lift or in high lift pull too large, resulting in extreme wear of thrust bearings and other components, the motor due to overload and burn. After put into the well, the measurement of the motor and the ground insulation resistance value, not less than 100M. After the start, regular observation of voltage and current, and check the motor winding insulation is in line with the requirements of the provisions. If the temperature of the storage site is below the freezing point, the water in the pump chamber should be drained to prevent the water in the motor chamber from freezing and damaging the motor due to low temperature.

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.After installing the submersible pump, recheck the insulation resistance and three-phase continuity switch, check whether there is any error in the connection between the instrument and the starting equipment.If there is no problem, you can start to test the machine. After starting, observe whether the indication reading of each instrument is correct.If the rated voltage and current specified on the nameplate are exceeded, please observe whether the pump has noise or vibration.If everything is normal, it can be put into operation. After the pump runs for the first time for four hours, the motor thermal insulation resistance should be closed and tested quickly. Its value should not be less than 0.5 megaohm. After the pump stops, it should be restarted after five minutes to prevent the water column in the pipeline from completely reversing, which will cause the motor to burn out due to excessive current.
•  
• 2.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 machine should be stopped immediately to troubleshoot.
• 1.Under the rated working condition, the current exceeds 20%.
• 2.The dynamic water level drops to the water inlet section, resulting in intermittent water.
• 3.The submersible pump has severe vibration or noise.
• 4.The supply voltage is lower than 340 volts.
• 5.A fuse is burned out.
• 6.The water pipeline is damaged.
• 7.The motor's insulation resistance to the geothermal state is lower than 0.5 megaohm.
•  
• 3.Unit disassembly:
• - Maak die kabelbinder los, verwyder die pyplyndeel en verwyder die draadplaat.
• - screw down the water bolt, put out the water in the motor chamber.
• - verwyder die filter, los die vaste skroef op die koppeling 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.the disassembly process of the motor is: (see figure 1) place the motor on the platform, and remove the nuts, base, shaft head locking nut, thrust plate, key, lower guide bearing seat and double head bolt from the bottom of the motor in turn, and then take out the rotor (pay attention not to damage the wire package) and finally remove the connecting section and upper guide bearing seat.
• 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.

 1, sit die water in die motorholte uit (veral in die winter om te verhoed dat die motor vries), en bind die kabel goed vas.

 2, store in an indoor room without corrosive substances and gases, with a temperature below 40 °C.
