 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.

Cov yam ntxwv tseem ceeb ntawm cov khoom muaj xws li:

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) Kev npaj ua ntej installation:
1. Xyuas seb lub twj tso kua mis submersible puas ua tau raws li qhov kev siv thiab qhov tshwj xeeb hauv phau ntawv qhia.
2. Siv lub qhov hnyav obiect nrog txoj kab uas hla sib npaug rau qhov siab tshaj plaws sab nraud ntawm lub twj tso kua mis submersible, ntsuas seb qhov inneldiameter ntawm lub qhov dej puas tuaj yeem haum rau lub twj tso kua mis submersible, thiab ntsuas seb qhov dej tob puas ua tau raws li qhov yuav tsum tau ua.

3. Xyuas seb lub qhov dej puas huv si thiab seb cov dej hauv qhov dej puas yog turbid. Tsis txhob siv lub tshuab hluav taws xob submersible los ntxuav lub welor twj av nkos thiab dej xuab zeb kom tsis txhob muaj kev puas tsuaj ntxov rau lub tshuab hluav taws xob submersible.

4. Tshawb xyuas seb txoj haujlwm ntawm lub welhead installation clamp puas haum thiab seb nws puas tuaj yeem tiv taus qhov zoo ntawm tag nrho chav tsev.

6. Unscrew cov dej ntsia hlau thiab sau cov kab noj hniav nrog cov dej huv, tsis muaj corrosive (ceeb toom. Nco ntsoov sau nws), tom qab ntawd ceev cov dej screws. Tom qab 12 teev ntawm kev txhaj tshuaj dej, qhov rwb thaiv tsev ntawm lub cev muaj zog yuav tsum tsis txhob tsawg dua 150M Q thaum ntsuas nrog 500V co lub rooj.
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

Daim duab txuas cable thaiv txheej txheem yog raws li hauv qab no:

8. Siv multimeter los xyuas seb cov xov hlau peb-theem puas txuas thiab seb qhov DC tsis kam yog kwv yees li qhov sib npaug.
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) Kev teeb tsa thiab cov cuab yeej siv:
1. Ib khub nqa cov hlua rau ntau tshaj ob tons.
2. Lub tripod nrog ib txoj kab ntsug qhov siab tsis pub tsawg tshaj plaub meters.
