 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.

3. Suriin kung malinis ang wellbore at kung ang tubig ng balon ay maputik. Huwag gumamit ng submersible electric pump upang hugasan ang welor pump na putik at tubig ng buhangin upang maiwasan ang maagang pagkasira ng submersible electric pump.

4. Suriin kung ang posisyon ng welhead installation clamp ay angkop at kung ito ay makatiis sa kalidad ng buong unit

5. Suriin kung ang mga bahagi ng submersible pump ay kumpleto at maayos na naka-install ayon sa assembly diagram sa manualAlisin ang filter screen at paikutin ang coupling upang makita kung ito ay umiikot nang flexible

6. Alisin ang turnilyo ng tubig at punan ang lukab ng motor ng malinis, hindi kinakaing unti-unti na tubig (tandaan. siguraduhing salaan ito), pagkatapos ay higpitan ang waterscrew. Pagkatapos ng 12 oras na pag-iniksyon ng tubig, ang insulation resistance ng motor ay hindi dapat mas mababa sa 150M Q kapag sinusukat sa isang 500V shaking table.
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

Ang naka-attach na cable wiring process diagram ay ang mga sumusunod:

8. Gumamit ng multimeter upang suriin kung ang mga three-phase na wire ay konektado at kung ang DC resistance ay tinatayang balanse.
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) Kagamitan at kasangkapan sa pag-install:

2. Isang tripod na may patayong taas na hindi bababa sa apat na metro.
3. Dalawang nakabitin na lubid (wire ropes) na kayang magdala ng bigat na higit sa isang tonelada (maaaring pasanin ang bigat ng isang kumpletong hanay ng mga water pump).
4. Mag-install ng dalawang pares ng clamps (splints).
5. Wrenches, martilyo, distornilyador, mga kasangkapang elektrikal at instrumento, atbp.

(3)Pag-install ng electric pump:
1. Ang diagram ng pag-install ng submersible electric pump ay ipinapakita sa Figure 2. Ang mga partikular na sukat ng pag-install ay ipinapakita sa Talahanayan 3 "Listahan ng Mga Dimensyon ng Pag-install ng Submersible Electric Pump".

2. Ang mga submersible electric pump na may ulo na wala pang 30 metro ay maaaring iangat nang direkta sa balon gamit ang mga hose at wire rope o iba pang mga lubid ng abaka na kayang pasanin ang buong bigat ng buong makina, mga tubo ng tubig, at tubig sa mga tubo.

3. Ang mga pump na may ulo na higit sa 30 metro ay gumagamit ng mga bakal na tubo, at ang pagkakasunud-sunod ng pag-install ay ang mga sumusunod:
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 Bahagyang iangat ang submersible pump, tanggalin ang clamp sa itaas na dulo ng water pump, itali ang cable sa pipe ng tubig gamit ang plastic tape, at dahan-dahang itali ito hanggang sa mailagay ang clamp sa wellhead.
④Gamitin ang parehong paraan upang itali ang lahat ng tubo ng tubig sa balon.
⑤Pagkatapos maikonekta ang lead-out cable sa control switch, ito ay konektado sa three-phase power supply.

(4) Mga bagay na dapat tandaan sa panahon ng pag-install:
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. Sa panahon ng pag-install, ang isang rubber pad ay dapat ilagay sa flange ng bawat pipe at higpitan nang pantay-pantay.
3. Kapag ang bomba ng tubig ay ibinaba sa balon, dapat itong ilagay sa gitna ng tubo ng balon upang maiwasan ang pagtakbo ng bomba sa dingding ng balon nang mahabang panahon, na nagiging sanhi ng pag-vibrate ng bomba at pagwalis at pagkasunog ng motor. .
4. Tukuyin ang lalim ng water pump sa ilalim ng balon ayon sa dumadaloy na buhangin at silt na kondisyon ng balon. Huwag ibaon ang bomba sa putik. Ang distansya mula sa water pump hanggang sa ilalim ng balon ay karaniwang hindi bababa sa 3 metro (tingnan ang Larawan 2).
5. Ang lalim ng pagpasok ng tubig ng water pump ay dapat na hindi bababa sa 1-1.5 metro mula sa dynamic na lebel ng tubig hanggang sa water inlet node (tingnan ang Larawan 2). Kung hindi, ang water pump bearings ay maaaring madaling masira.
6. Ang pagtaas ng water pump ay hindi maaaring masyadong mababa. Kung hindi, kailangang mag-install ng gate valve sa wellhead water pipeline para makontrol ang pump flow sa rated flow point para maiwasang ma-overload at masunog ang motor dahil sa malalaking flow rate.
7. Kapag ang water pump ay tumatakbo, ang tubig na output ay dapat na tuluy-tuloy at kahit na, ang kasalukuyang ay dapat na stable (sa ilalim ng rated working conditions, sa pangkalahatan ay hindi hihigit sa 10% ng rated current), at dapat walang vibration o ingay. Kung mayroong anumang abnormalidad, dapat na ihinto ang makina upang malaman ang sanhi at maalis ito.
8. Kapag nag-i-install, bigyang-pansin ang setting ng grounding wire ng motor (tingnan ang Figure 2). Kapag ang tubo ng tubig ay isang bakal na tubo, akayin ito mula sa wellhead clamp; kapag ang tubo ng tubig ay isang plastik na tubo, akayin ito mula sa marka ng saligan ng electric pump.
