The pump part is mainly composed of pump shaft, impeller, shunt 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 discharging ring, water inlet section, lead cable and other components. The main characteristic of this product is that the motor is a water-cooled submersible three-phase asynchronous motor, and the motor cavity is filled with water to cool the motor and lubricate the bearing. The pressure regulating diaphragm at the bottom is used to adjust the expansion-contraction pressure difference in the body caused by the change of the temperature rise of the motor. In order to prevent the sand particles in the well water from entering the motor, two oil seals are installed at the upper end of the motor shaft extension, and a sand discharging ring is installed to form a sand discharging structure. In order to prevent the pump shaft from jumping when starting, the pump shaft and the motor shaft are connected together through a coupling, and a thrust bearing is installed at the bottom of the motor. The lubrication of the motor and the pump bearing is realized through water lubrication. The stator winding of the motor is made of high-quality well motor winding wire, with high insulation performance. The pump is designed by computer CAD, with simple structure and good technical performance.

(4) Rudaí le tabhairt faoi deara le linn na suiteála:
1. Má aimsítear feiniméan jamming le linn an phróisis caidéalaithe, cas nó tarraing an píopa uisce chun an pointe jamming a shárú. Mura n-oibríonn bearta éagsúla fós, le do thoil Ná cuir an caidéal síos chun damáiste a sheachaint don chaidéal leictreach intumtha agus don tobar.
2. Le linn na suiteála, ba chóir eochaircheap rubair a chur ar flange gach píopa agus é a cheangal go cothrom.
3. Nuair a íslítear an caidéal uisce isteach sa tobar, ba chóir é a chur i lár an phíobáin tobair chun an caidéal a chosc ó bheith ag rith i gcoinne bhalla an tobair ar feadh i bhfad, rud a fhágann go mbeidh an caidéal ag creathadh agus an mótar a scuabadh agus a dhó. .
4. Déan doimhneacht an chaidéil uisce go bun an tobair a chinneadh de réir coinníollacha sreafa gaineamh agus siolta an tobair. Ná cuir an caidéal sa láib. De ghnáth ní lú ná 3 mhéadar an fad ón gcaidéal uisce go bun an tobair (féach Fíor 2).
5. Níor cheart go mbeadh doimhneacht iontrála uisce an chaidéil uisce níos lú ná 1-1.5 méadar ón leibhéal uisce dinimiciúil go dtí an nód inlet uisce (féach Fíor 2). Seachas sin, féadfar damáiste a dhéanamh go héasca ar imthacaí an chaidéil uisce.
6. Ní féidir le hardaitheoir an chaidéil uisce a bheith ró-íseal. Seachas sin, is gá comhla geata a shuiteáil ar phíblíne uisce an tobair chun sreabhadh an chaidéil ag an bpointe sreafa rátáilte a rialú chun an mótar a chosc ó ró-ualach agus a dhó mar gheall ar rátaí sreafa móra.
7. Nuair a bhíonn an caidéal uisce ag rith, ba cheart go mbeadh an t-aschur uisce leanúnach agus fiú, ba cheart go mbeadh an sruth cobhsaí (faoi choinníollacha oibre rátáilte, go ginearálta gan níos mó ná 10% den sruth rátáilte), agus níor cheart go mbeadh aon chreathadh nó torann ann. Má tá aon neamhghnáchaíocht ann, ba chóir an meaisín a stopadh chun an chúis a fháil amach agus é a dhíchur.
8. Nuair a shuiteáil tú, tabhair aird ar shocrú na sreinge talún mótair (féach Fíor 2). Nuair is píopa cruach é an píopa uisce, déan é a threorú as clamp an tobair; nuair is píopa plaisteach an píopa uisce, é a threorú ó mharc talún an chaidéil leictreach.
After installation of the underwater pump, it is necessary to recheck the insulation resistance and three-phase continuity of the switch, and check whether the connection between the instrument and the starting equipment is wrong. 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, it can be put into operation. Four hours after the first operation of the pump, it should be turned off and the thermal insulation resistance of the motor should be quickly tested, and its value should not be less than 0.5 megaohm. After stopping the pump, it should be restarted after an interval of five minutes 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 stopped immediately to eliminate the fault:
1 the current exceeds 20% under the rated working condition.
2 the dynamic water level drops to the inlet section, resulting in intermittent drainage.
3 the underwater pump vibrates violently or emits huge noise.
4 the supply voltage is lower than 340 volts.
5 a fuse is burned.
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 device, it is necessary to untie the cable bundle and remove the pipeline part and the line protection plate. Remove the drain bolt and exclude all water in the motor chamber. Remove the filter element and loosen the screw on the coupling fixed to the motor shaft. Unscrew the bolt connecting the water inlet section and the motor, and separate the pump and the motor (pay attention to placing the device horizontally when separating to prevent the bending of the pump shaft). The sequence of disassembling the pump is as follows: (see Figure 1) water inlet section, impeller, water inlet shell, impeller. Check the valve body, and use a special tool to loosen the cone sleeve fixed to the impeller when removing the impeller. In the process of disassembly, avoid bending the pump shaft and damaging various components. The disassembly process of the motor is as follows: (see Figure 1) put the motor on the platform, and remove the nuts on the screw (pull rod bolt), base, shaft head lock nut, thrust plate, key and lower guide rail - bearing seat, bolt, and then remove the rotor (be careful not to damage the wiring harness), and finally remove the connecting parts and upper guide bearing seat. Unit assembly: before assembly, the rust and dirt of each component should be cleaned, and the sealant should be coated on each mating surface and fastener, and then assembled in the opposite order of disassembly (the movement of the motor shaft after assembly is about one millimeter), after the assembly is completed, the coupling should be flexibly rotated, and then the filter element should be placed for testing. Each time the underwater electric pump has been used for one year, or less than one year but has been immersed for two years, it must be disassembled and inspected in accordance with Article 5 and replace the worn parts.
1, cuir an t-uisce amach sa chuas mótair (go háirithe sa gheimhreadh chun an mótar a chosc ó reo), agus an cábla a cheangal go maith.
2, stóráil i seomra faoi dhíon gan substaintí agus gáis creimneach, ag teocht faoi bhun 40 ° C.
