The pump part is mainly composed of pump shaft, impeller, flow guide housing, rubber bearing, check valve body (optional) and other parts. 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 discharging ring, water inlet section, lead cable and other parts. The main features of the product include: the motor is a water-filled wet submersible three-phase asynchronous motor, the motor cavity is filled with clear water for cooling the motor and lubricating the bearing, the pressure regulating diaphragm at the bottom of the motor is used to adjust the pressure difference caused by the heating of the motor. In order to prevent the sand in the well water from entering the motor, the upper end of the motor shaft extension is installed with two oil seals, and the sand discharging ring is installed to form a sand prevention structure. In order to avoid the pump shaft 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. The lubrication of the motor and the pump bearing is water lubrication, and the stator winding of the motor uses high quality submersible motor wire with high insulation performance. The pump is designed by computer CAD, with simple structure and superior technical performance.

6. Lub nqa ntawm lub twj tso kua dej tsis tuaj yeem qis dhau. Txwv tsis pub, lub rooj vag valve yuav tsum tau muab tso rau ntawm lub qhov dej hauv qhov dej los tswj lub twj tso kua mis ntawm qhov ntsuas qhov taw tes kom tsis txhob muaj lub cev muaj zog los ntawm overloaded thiab hlawv tawm vim qhov txaus txaus.
7. Thaum lub twj tso kua dej ua haujlwm, cov dej tso tawm yuav tsum tsis tu ncua thiab txawm tias, qhov tam sim no yuav tsum ruaj khov (raws li kev ntsuas kev ua haujlwm, feem ntau tsis pub tshaj 10% ntawm cov ntsuas tam sim no), thiab yuav tsum tsis muaj kev vibration lossis suab nrov. Yog tias muaj qhov txawv txav, lub tshuab yuav tsum tau nres kom paub qhov ua rau thiab tshem tawm nws.
8. Thaum txhim kho, xyuam xim rau qhov chaw ntawm lub cev muaj zog grounding hlau (saib daim duab 2). Thaum cov yeeb nkab dej yog cov yeeb nkab steel, coj nws los ntawm lub qhov dej zoo clamp; thaum cov yeeb nkab dej yog cov yeeb nkab yas, coj nws los ntawm cov cim hauv av ntawm lub tshuab hluav taws xob.

When the submersible pump is installed, recheck the insulation resistance and three-phase connectivity of the switch, and check whether there is any error in the connection between the instrument and the starting equipment. If there is no problem, you can start the test 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, observe whether the pump has any noise or vibration. If everything is normal, you can put into operation. After the first start of the pump for four hours, it should be closed and the thermal insulation resistance of the motor should be quickly tested. Its value should not be less than 0.5 megaohm. After stopping the pump, it should be restarted after a five-minute interval to prevent the water column in the pipeline from completely reversing, resulting in the motor burning due to excessive current. After the pump is put into normal operation, in order to prolong its service life, it is necessary to check regularly whether the supply voltage, working current and insulation resistance are normal. If the following conditions are found, the machine should be shut down immediately to eliminate the fault:

1.the current exceeds 20% under the rated working conditions.

2.the dynamic water level drops to the inlet section, resulting in intermittent drainage.

3.the submersible pump vibrates violently or emits huge noise.

4.the supply voltage is lower than 340 volts.

5.a fuse is blown out.

6.the water pipe is damaged.

7.the thermal insulation resistance of the motor to the ground is less than 0.5 megaohm.

When disassembling the unit:

1.lock the cable, take off the pipeline part, and remove the line protection plate.

2.unscrew the drain bolt, empty all the water in the motor chamber.

3.remove the filter, loosen the screw on the coupling fixed motor shaft.

4.unscrew the bolt connecting the water inlet section and the motor, and separate the pump and the motor (pay attention to the leveling unit 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, guide housing, rotor, impeller. Check the valve body. When removing the impeller, use special tools to loosen the conical sleeve fixed on the impeller. In the process of disassembly and assembly, avoid bending the pump shaft and damaging various parts.

6.the disassembly process of the motor is: (see Figure 1) put the motor on the platform, remove the nut, base, shaft head lock nut, thrust plate, key, lower guide rail, support seat, and tie rod bolt from the bottom of the motor in order, and then take out the rotor (be careful not to damage the wiring harness), and finally remove the connecting part and the upper guide rail bearing seat. When assembling the unit: before assembly, rust and dirt on each part should be cleaned and sealant coated on each mating surface and fastener, then assembled in reverse order of disassembly (motor shaft movement after assembly is about 1 mm), after assembly, coupling should be flexible, then put on the filter for testing. Each submersible pump running for one year, or if the running time is less than one year but has been immersed for two years, it must be disassembled and inspected according to Article 5 to replace worn parts.

 1, muab cov dej tso rau hauv lub cav cav (tshwj xeeb tshaj yog nyob rau lub caij ntuj no los tiv thaiv lub cev tsis muaj zog), thiab khi lub cable zoo.

 2, cia nyob rau hauv ib chav tsev tsis muaj corrosive tshuaj thiab gases, nrog ib tug kub ntawm 40 ° C.

 3, kev siv mus sij hawm ntev yuav tsum tau them sai sai rau kev tiv thaiv xeb ntawm cov twj submersible.
