Kev Tiv Thaiv Kev Nyab Xeeb

This well submersible pump is a clean water pump. It is strictly prohibited to dig new wells and extract sediment and turbid water. The voltage grade of the well pump is 380/50HZ. Other submersible motors with different voltage grades need to be customized. Underground cables must be waterproof and equipped with starting equipment, such as distribution boxes, etc. The starting equipment should have conventional comprehensive motor protection functions, such as short circuit overload protection, phase loss protection, undervoltage protection, grounding protection and idling protection. In abnormal cases, the protection device should be tripped in time. The pump must be reliably grounded when installed and used. It is prohibited to push and pull the switch when the hands and feet are wet. The power must be cut off before installation and maintenance of the pump. The place where the pump is used must be clearly marked with "anti-electric shock". Before going down the well or installation, the motor must be filled with distilled water or non-corrosive clean cold water. The intake/drain bolts must be tightened. When testing the pump on the ground, water must be added to the pump chamber to lubricate the rubber bearings. The instantaneous start should not exceed one second to check whether the direction is correct. This is also applicable to direction indication. When using the vertical electric pump, pay attention to safety to prevent overturning and injury. Strictly in accordance with the provisions of the pump lift and flow range of use, to prevent the pump in low lift has a large flow or high lift has a large pull, resulting in extreme wear of thrust bearings and other parts, so that the motor overload burned. After the pump into the well, the measurement of the insulation resistance between the motor and the ground shall not be less than 100MΩ. After the start, regular observation of voltage and current, and check whether the motor winding insulation meets the requirements of the provisions. If the pump storage location temperature is below freezing, the water in the motor cavity should be drained to prevent freezing in the motor cavity and damage the motor due to low temperature.

4. Txiav txim siab qhov tob ntawm lub twj tso kua mis dej mus rau hauv qab ntawm lub qhov dej raws li cov xuab zeb ntws thiab cov av ntawm lub qhov dej. Tsis txhob faus lub twj tso kua mis hauv av nkos. Qhov kev ncua deb ntawm lub twj tso kua dej mus rau hauv qab ntawm lub qhov dej yog feem ntau tsis pub tsawg tshaj 3 meters (saib daim duab 2).
5. Qhov dej nkag qhov tob ntawm lub twj tso kua mis dej yuav tsum tsis pub tsawg tshaj 1-1.5 meters los ntawm cov dej dynamic mus rau qhov dej nkag ntawm qhov dej (saib daim duab 2). Txwv tsis pub, cov dej twj tso kua mis bearings yuav yooj yim puas.
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.

Kev tu thiab tu

（1）After the submersible pump is installed, check the insulation resistance and three-phase conduction from the switch again, check whether the instrument and the connection of the start equipment are wrong, if there is no problem, the trial machine can be started, and observe whether the indicator readings of the instrument exceed the rated voltage and current specified on the nameplate after the start, and observe whether the pump has noise and vibration phenomenon, and put into operation if everything is normal.
（2）After the first operation of the pump for four hours, the motor should be shut down to test the thermal insulation resistance quickly, and its value should not be less than 0.5 megaohm.
（3）After the pump is shut down, it should be started after five minutes to prevent the water column in the pipe from being completely reflowed and causing excessive motor current and burnout.
（4）After the pump is put into normal operation, in order to prolong its service life, it is necessary to check whether the supply voltage, working current and insulation resistance are normal regularly. If the following conditions are found, the pump should be shut down immediately to troubleshoot.
1 In the rated condition, the current exceeds 20%.
2 Lub dynamic dej theem poob mus rau hauv cov dej inlet seem, ua rau cov dej tsis sib xws.
3 Lub twj tso kua mis submersible muaj kev vibration loj lossis suab nrov.
4 Cov khoom siv hluav taws xob qis dua 340 volts.
5 Ib lub fuse raug hlawv.
6 Lub raj xa dej puas lawm.
7 The motor's thermal insulation resistance is lower than 0.5 megaohm.
（5）Unit disassembly:
1 Untie the cable tie, remove the pipeline part, and remove the wire plate.
2 ntsia hlau ntsia hlau dej, muab cov dej tso rau hauv lub cav tsav.
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.

Kev ruaj ntseg thiab kev tuav pov hwm
