 The well submersible pump is a pump suitable for clear water. It is strictly prohibited to dig new wells and pump out mud and sand. The voltage grade of the well pump is 380V/50HZ, and other voltage grades of the submersible motor need to be customized. Underground cables must be waterproof cables and must be equipped with starting equipment, such as distribution box, etc. The starting equipment should have common motor comprehensive protection functions, such as short circuit overload protection, phase loss protection, undervoltage protection, grounding protection and idling protection, etc. In abnormal cases, the protective device should be tripped in time. When installing and using the pump, it must be firmly grounded. It is prohibited to push and pull the switch when the hands and feet are wet. The power supply must be cut off before installing and maintaining the pump. An obvious "anti-electric shock" sign must be set up where the pump is used. Before going down the well or installing the motor, the inner cavity must be filled with distilled water or non-corrosive clean cold water, and the water injection/drainage bolts must be tightened. Fill the pump with water for ground test to lubricate the rubber bearings. The instant start time shall not exceed one second to check whether the direction is correct and consistent with the direction indication. Be sure to pay attention to safety when placing the pump upright to prevent overturning and causing injury. Strictly in accordance with the provisions of the pump lift and flow range of use, to prevent the pump flow at low lift or excessive pull at high lift, resulting in extreme wear of thrust bearings and other components, resulting in motor overload burn. After the pump into the well, the insulation resistance between the motor and the ground shall be measured, which shall not be less than 100MΩ. After the start, observe the voltage and current regularly, and check the motor winding insulation, to see if it meets the requirements; if the pump storage temperature is below the freezing point, the water in the motor cavity should be discharged, so as to avoid the water in the motor cavity freezing and damaging the motor due to low temperature.

The pump part is mainly composed of pump shaft,impeller,diversion shell,rubber bearing,check valve body(optional)and other components.The motor part is mainly composed of base,pressure regulating diaphragm,thrust bearing,thrust plate,lower guide bearing seat,stator,rotor,upper guide bearing seat,sand ring,water inlet section,lead cable and other components.

De vigtigste egenskaber ved produktet omfatter:

1.The motor is a water-loaded wet submersible three-phase asynchronous motor,and the motor cavity is filled with clean water for cooling the motor and lubricating the bearing.The regulating diaphragm at the bottom of the motor is used to adjust the expansion and contraction pressure difference inside and outside the body caused by the temperature rise of the motor.
2.In order to prevent the sand particles in the well water from entering the motor,two oil seals are installed at the extension end of the motor shaft,and the sand ring is installed to form a sand prevention structure.
3.In order to prevent the pump shaft from jumping when starting,the pump shaft is connected with the motor shaft through a coupling,and the thrust bearing is installed at the bottom of the motor.
4.The lubrication of the motor and the pump bearing is water lubrication.
5.The stator winding of the motor adopts high-quality submersible motor winding wire,with excellent insulation performance.
6.The pump is designed by computer CAD,with simple structure and excellent technical performance.

(1) Forberedelse før installation:
1. Kontroller, om dykpumpen opfylder de brugsbetingelser og omfang, der er specificeret i manualen.
2. Brug en tung genstand med en diameter svarende til den maksimale ydre diameter af dykpumpen, mål om brøndboringens indvendige diameter kan passe til dykpumpen, og mål om brønddybden opfylder installationskravene.

3. Tjek om brøndboringen er ren, og om brøndvandet er grumset. Brug aldrig en elektrisk dykpumpe til at vaske welorpumpens mudder og sandvand for at undgå for tidlig beskadigelse af den elektriske dykpumpe.

4. Kontroller, om placeringen af ​​brøndhovedinstallationsklemmen er passende, og om den kan modstå hele enhedens kvalitet

5. Tjek om dykpumpens komponenter er komplette og installeret korrekt i henhold til monteringsdiagrammet i manualen Fjern filterskærmen og drej koblingen for at se om den roterer fleksibelt

6. Skru vandskruen af ​​og fyld motorhulrummet med rent, ikke-ætsende vand (bemærk. sørg for at fylde det op), og spænd derefter vandskruen. Efter 12 timers vandindsprøjtning bør motorens isolationsmodstand ikke være mindre end 150M Q målt med et 500V rystebord.
7. 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

Det vedhæftede kabelledningsdiagram er som følger:

8. Brug et multimeter til at kontrollere, om de trefasede ledninger er tilsluttet, og om DC-modstanden er tilnærmelsesvis afbalanceret.
9. Check whether the circuit and transformer capacity are overloaded, and then connect the overload protection switch or starting equipment. See Table 2 for specific models, and then
Pour a bucket of water into the water pump from the water pump outlet to lubricate the rubber bearings in the pump, and then place the submersible electric pump upright and steady.
Start (no more than one second) and check whether the steering direction is consistent with the steering sign. If not, swap any two connectors of the three-phase cable.
Then install the filter and prepare to go down the well. If used in special occasions (such as ditches, ditches, rivers, ponds, ponds, etc.), the electric pump must be reliably grounded.

(2) Installationsudstyr og værktøjer:
1. Et par løftekæder til mere end to tons.
2. Et stativ med en lodret højde på ikke mindre end fire meter.
3. To hængereb (wirereb), der kan bære en vægt på mere end et ton (kan bære vægten af ​​et komplet sæt vandpumper).
4. Installer to par klemmer (skinne).
5. Skruenøgler, hamre, skruetrækkere, elektrisk værktøj og instrumenter mv.

(3) Installation af elektrisk pumpe:
1. Installationsdiagrammet for den dyk-elektriske pumpe er vist i figur 2. De specifikke installationsdimensioner er vist i Tabel 3 "Liste over installationsdimensioner for den dyk-elektriske pumpe".

2. Dykpumper med en løftehøjde på mindre end 30 meter kan hejses direkte ned i brønden ved hjælp af slanger og ståltove eller andre hamperove, der kan bære den fulde vægt af hele maskinen, vandrør og vand i rørene.

3. Pumper med en løftehøjde på mere end 30 meter anvender stålrør, og installationsrækkefølgen er som følger:
①Use a clamp to clamp the upper end of the water pump part (the motor and water pump have been connected at this time), lift it with a hanging chain, and slowly tie it into the well until
Put the clamp on the wellhead and remove the hanging chain.
② Use another pair of clamps to clamp a pipe, lift it with a hanging chain 15 cm away from the flange, and lower it slowly. Between pipe flange and pump flange
Put the rubber pad in place and tighten the pipe and pump evenly with bolts, nuts and spring washers.
③ Løft dykpumpen lidt, fjern klemmen på den øverste ende af vandpumpen, bind kablet fast til vandrøret med et plastikbånd, og bind det langsomt ned, indtil klemmen er placeret ved brøndhovedet.
④Brug samme metode til at binde alle vandrør i brønden.
⑤ Efter at udløbskablet er tilsluttet kontrolkontakten, tilsluttes det til den trefasede strømforsyning.

(4) Ting at bemærke under installationen:
1. If a jamming phenomenon is found during the pumping process, turn or pull the water pipe to overcome the jamming point. If various measures still do not work, please
Do not force the pump down to avoid damage to the submersible electric pump and the well.
2. Under installationen skal der placeres en gummipude ved flangen på hvert rør og strammes jævnt.
3. Når vandpumpen sænkes ned i brønden, skal den placeres i midten af ​​brøndrøret for at forhindre pumpen i at køre mod brøndvæggen i lang tid, hvilket får pumpen til at vibrere og motoren til at feje og brænde .
4. Bestem dybden af ​​vandpumpen til bunden af ​​brønden i henhold til brøndens flydende sand- og siltforhold. Begrav ikke pumpen i mudderet. Afstanden fra vandpumpen til bunden af ​​brønden er generelt ikke mindre end 3 meter (se figur 2).
5. Vandpumpens vandindgangsdybde bør ikke være mindre end 1-1,5 meter fra den dynamiske vandstand til vandindløbsknuden (se figur 2). Ellers kan vandpumpens lejer let blive beskadiget.
6. Vandpumpens løft må ikke være for lavt. Ellers skal der installeres en skydeventil på brøndhovedets vandrørledning for at styre pumpeflowet ved det nominelle flowpunkt for at forhindre, at motoren bliver overbelastet og brændt ud på grund af store flowhastigheder.
7. Når vandpumpen kører, skal vandudgangen være kontinuerlig og jævn, strømmen skal være stabil (under nominelle arbejdsforhold, generelt ikke mere end 10% af nominel strøm), og der bør ikke være vibrationer eller støj. Hvis der er noget unormalt, skal maskinen standses for at finde ud af årsagen og eliminere den.
8. Når du installerer, skal du være opmærksom på indstillingen af ​​motorens jordledning (se figur 2). Når vandrøret er et stålrør, før det fra brøndhovedklemmen; når vandrøret er et plastikrør, før det fra jordingsmærket på den elektriske pumpe.
