Kev Tiv Thaiv Kev Nyab Xeeb

1, well submersible pump for clean water pump, prohibit the new well, pumping sediment and muddy water,

2, well water pump voltage grade of 380/50HZ, the use of other voltage grades of submersible motors need to be customized. The underground cable must use waterproof cable, must be equipped with starting equipment, such as distribution box, start not ready should have commonly used motor comprehensive protection function, such as short circuit overload protection, phase protection, undervoltage protection, grounding protection, idling protection, in case of abnormal conditions, the protection device should be timely action trip.

3, the installation and use of the pump must be reliably grounded, prohibit the push and pull switch when the hands and feet are wet, the installation and maintenance of the pump must be cut off the power supply, the use of the pump place to set up "to prevent electric shock" obvious signs:

4, down the well or before installation, the motor cavity must be filled with distilled water or non-corrosive clean cold boiling water, tighten the / water bolt, the pump on the ground test run, must be to the pump chamber water lubrication rubber bearings, instant start not more than a second, see whether the steering is the same as the steering instructions. When the pump is upright, pay attention to safety, prevent overturning injury.

5, nruj me ntsis raws li cov kev cai ntawm lub twj tso kua mis nqa, ntws ntau yam ntawm kev siv, los tiv thaiv qis ntws los yog siab nqa twj tso kua mis quab yuam, lub thrust bearing thiab lwm yam ntawm hnav, lub cev muaj zog overload hlawv.

6, after the pump down the well, the measurement of the motor to the ground insulation resistance should not be less than 100M, after the start to observe the voltage and current, check the motor winding insulation, whether in line with the requirements; pump storage location temperature if less than freezing point, should be dry the motor cavity water, prevent the motor cavity water ice damage caused by low temperature.

Taw qhia txog Cov Qauv

The pump parts are mainly composed of pump shaft, impeller, shunt shell, rubber bearing, check valve body and so on; the motor part mainly includes base, pressure regulating diaphragm, thrust bearing, thrust plate, lower guide bearing seat, stator, rotor, upper guide bearing seat, sand discharging ring, water inlet section, cable lead, etc. The main characteristic of the product is that the motor is a water-filled wet submersible three-phase asynchronous motor, the motor cavity is filled with water, used to cool the motor and lubricate the bearing; the pressure regulating diaphragm at the bottom is used to adjust the expansion and contraction pressure difference of the internal water 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 sand sealing rings are installed on the upper end of the motor shaft extension, and a sand discharging ring is installed to form a sand prevention structure. To prevent the pump shaft from jumping when starting up, the pump shaft is connected with the motor shaft through a coupling, and the thrust bearing is installed on the lower part of the motor. The motor and pump bearing adopt water lubrication technology, and the stator winding of the motor adopts high quality submersible motor winding with high insulation performance. The pump is designed by computer CAD, with simple structure and excellent technical performance.

1 Untie the cable tie, remove the pipeline part, and remove the wire plate. 2 screw down the water bolt, put the water in the motor chamber.
3 tshem tawm cov lim, xoob cov ntsia hlau ruaj khov ntawm lub coupling los txhim kho lub cev muaj zog.
4 ntsia hlau ntsia hlau txuas cov dej nkag nrog lub cev muaj zog, thiab cais lub twj tso kua mis los ntawm lub cev muaj zog (ua tib zoo saib lub tog hauv ncoo thaum sib cais, txhawm rau tiv thaiv kev khoov ntawm lub twj tso kua mis ncej)
5 qhov sib txawv ntawm lub twj tso kua mis yog: (saib daim duab 1) cov dej nkag, impeller, diversion plhaub, impeller ...... kos valve lub cev, thaum tshem lub impeller, siv cov cuab yeej tshwj xeeb los xoob lub tes tsho conical ntawm qhov ruaj khov. impeller ua ntej, thiab tsis txhob khoov thiab bruising lub twj tso kua mis ncej nyob rau hauv tus txheej txheem ntawm disassembly.
6 cov txheej txheem disassembly ntawm lub cev muaj zog yog: (saib daim duab 1) muab lub cev muaj zog rau ntawm lub platform, thiab tshem cov txiv ntseej, hauv paus, lub taub hau xauv lub taub hau, lub phaj thrust, qhov tseem ceeb, qis qhia cov kabmob lub rooj zaum thiab ob lub taub hau ntsia liaj qhov rooj los ntawm hauv qab ntawm lub cev muaj zog tig, thiab tom qab ntawd tshem tawm lub rotor (ua tib zoo saib kom tsis txhob puas lub pob hlau) thiab thaum kawg tshem tawm cov ntu txuas thiab sab sauv coj lub rooj zaum.
7 chav sib dhos: ua ntej sib dhos, cov xeb thiab av ntawm qhov chaw yuav tsum tau ntxuav, thiab cov mating nto thiab fasteners coated nrog sealant, thiab ces sib sau ua ke nyob rau hauv lub opposite kev txiav txim ntawm disassembly (lub cev muaj zog ncej txav mus thiab down tom qab sib dhos rau txog ib millimeter), tom qab sib dhos, qhov sib txuas yuav tsum hloov tau, thiab tom qab ntawd lub tshuab lim tshuaj ntsuam xyuas. Lub twj tso kua mis submersible yuav tsum tau muab tshem tawm ntawm lub qhov dej rau kev rhuav tshem thiab tu raws li Tshooj 5 tom qab ua haujlwm ib xyoos, lossis tsawg dua ib xyoos ntawm kev ua haujlwm tab sis ob xyoos ntawm lub sijhawm dhia dej, thiab cov khoom hnav yuav tsum tau hloov.
