Roj leakage yog ib qho uas pom tau tshaj plaws -thiab zam tau- teeb meem zoo hauv ib qho -theem faib transformer. Thaum lub tsev tau teeb tsa rau ntawm tus ncej hluav taws xob, txawm tias qhov pom me me tuaj yeem ua rau sab nrauv, txo cov roj thiab tsim cov kev pabcuam kim. Kev kho kuj tseem nyuaj dua ntawm qhov siab dua hauv kev cob qhia.
Vim li ntawd, kev tiv thaiv leakage hauv ancej-mounted transformer roj tankyuav tsum pib ua ntej welding. Lub tank tsim, kev tsim steel, kev sib koom ua ke, cov khoom siv sib txuas thiab kev soj ntsuam txhua qhov cuam tshuam ntev - lub sij hawm sealing kev ua tau zoo. Cov yim tswj hauv qab no hais txog cov ntsiab lus uas muaj teeb meem feem ntau pib.
1. Pib nrog qhov raug Tank Structure thiab Steel Thickness
Lub tank yuav tsum tau tsim los rau lub transformer roj ntim, active - ib feem qhov hnyav, kev khiav hauj lwm kub thiab teev nyob rau hauv - tej yam kev mob siab. Tsuas yog nce phaj tuab tsis tuaj yeem tiv thaiv kom tsis txhob yaig. Qhov chaw tsis zoo los yog qhov chaw nruj heev tuaj yeem ua rau muaj kev ntxhov siab thiab ua rau muaj kev puas tsuaj rau lub vuam.
Rau ib lub cylindrical ib zaug -theem tank, daim duab kos yuav tsum txhais lub plhaub txoj kab uas hla, phaj thickness, hauv qab siv, npog interface thiab ntxiv dag zog nyob ib ncig ntawm lifting los yog mounting cov ntsiab lus. Tus tsim yuav tsum tau tso cai rau cov roj expansion thiab siab variation thaum lub sij hawm kev pab cuam.
2. Tswj Cylindrical Plhaub tsim thiab Joint Fit-Up
Kev sib sau raug ua kom txhim khu kev qha vuam yooj yim dua. Yog tias lub plhaub dov tawm ntawm qhov puag ncig, cov neeg ua haujlwm yuav tsum tau yuam cov npoo ua ke, tsim qhov tsis sib xws thiab qhov seem seem.
Ua ntej vuam, cov chaw tsim khoom yuav tsum xyuas lub plhaub puag ncig, sib koom ua ke, qhov sib txawv hauv paus thiab tack -weld txoj hauj lwm. Kev sib haum xeeb-up pab tswj kev nkag mus raws tag nrho cov seam thiab txo qhov kev pheej hmoo ntawm porosity, kub hnyiab- los ntawm thiab tsis tiav fusion hauv ib qhoib zaug -theem ncej-mounted transformer tank.
3. Siv cov txheej txheem vuam tsim nyog rau qhov tseem ceeb ntawm lub tank seams
Longitudinal plhaub seams, circumferential hauv qab seams thiab welded accessory kev sib txuas tsim nyog tshwj xeeb. Cov pob qij txha no tseem raug rau cov roj thoob plaws hauv lub tshuab hluav taws xob lub neej kev pabcuam, yog li kev pom ib leeg tsis yog tus qauv lees paub txaus.
Vuam tsis sib xws yuav tsum phim cov khoom qib, phaj thickness, sib koom ua ke thiab ntau lawm txoj hauj lwm. Welders tsim nyog yuav tsum tswj cov cua kub nkag, mus ncig ceev thiab pib- chaw nres tsheb. Crater tawg, undercut, ntau spatter thiab tsis tau seem yuav tsum tau kho ua ntej kuaj.
4. Txhawb nqa Bushings, npog thiab cov khoom siv txuas ntxiv
Leaks tsis tshwm sim tsuas yog nyob rau hauv loj tank seams. Bushing qhib, ntws li qub, siab-relief fittings, grounding pads and cover connections are common weak point because they do welding with concentrated mechanical loads.
Nozzles thiab tus thawj coj yuav tsum zaum square rau lub plhaub yam tsis tau rub mus rau hauv txoj hauj lwm thaum vuam. Daim duab pom zoo yuav tsum muaj kev tshem tawm txaus rau kev vuam, txheej thiab tu. On ibcylindrical transformer roj tank, cov neeg coob coob tuaj yeem nkaum qhov teeb meem me me kom txog thaum lub transformer puv.
5. Xaiv Roj -Resistant Gaskets thiab Tswj Bolt Tightening
Txawm tias lub suab welded tank tuaj yeem xau ntawm lub hau npog lossis cov khoom siv bolted. Cov khoom siv gasket yuav tsum sib haum nrog cov kua insulating, kev khiav hauj lwm - qhov kub thiab txias thiab xav tau compression. Lub gasket npaj rau cov roj ntxhia yuav tsum tsis txhob raug lees txais rau lub ntuj tsim -ester-filled transformer yam tsis muaj kev lees paub.
Flange nto yuav tsum tiaj tus, huv si thiab tsis muaj txheej txheej khiav, weld spatter los yog sib sib zog nqus khawb. Bolts yuav tsum tau nruj me ntsis nyob rau hauv ib tug tswj tus ntoo khaub lig qauv kom gasket compression tseem txawm. Cov torque ntau dhau tuaj yeem ua rau lub hau nyias nyias lossis tshem tawm lub gasket, thaum tsis txaus torque tawm hauv txoj hauv kev rau seepage.
6. Ua kom tiav kev kuaj dej ua ntej txheej txheej
Kev ntsuam xyuas yuav tsum tshwm sim tom qab kev tsim khoom thiab kev tshuaj xyuas qhov ntev tab sis ua ntej blasting, pleev xim lossis hmoov txheej. Yog tias lub vuam yuav tsum tau kho, qhov kev sib txuas no tiv thaiv kev puas tsuaj rau cov txheej txheem tiav thiab tso cai rau qhov chaw kho kom rov kuaj dua.
Rau ib zaug xwb -theem cylindrical tank, huab cua- kev ntsuas siab ua ke nrog rau hauv dej yog siv tau thaum tso cai los ntawm cov txheej txheem pom zoo. Lub tank yog kaw, pressurized rau tus nqi pom zoo thiab soj ntsuam rau npuas nyob ib ncig ntawm welds thiab interfaces. Siab, tuav lub sij hawm thiab kev lees txais yuav tsum ua raws li tus neeg yuav khoom specification. Txhua qhov taw qhia yuav tsum raug cim, kho thiab rov kuaj dua.
7. Tiv thaiv Sealing Surfaces thaum lub sij hawm ntim thiab thauj
A leak-tested ncej-mounted transformer oil tanktseem tuaj yeem raug puas tsuaj ua ntej nws mus txog cov kab sib dhos. Cov flanges uas tsis muaj kev tiv thaiv yuav raug khawb, npog tuaj yeem cuam tshuam raws li cov khoom sib dhos thiab cov khoom sib txuas tuaj yeem raug ntaus thaum lub forklift lossis thawv tuav.
Kev ntim khoom yuav tsum txhawb nqa lub tank ntawm cov ntsiab lus tsim nyog thiab tiv thaiv hlau - mus rau - hlau txav. Machined ntsej muag, threaded kev sib txuas thiab qhib yuav tsum tau npog ib ntus. Cov lus qhia nqa yuav tsum yog qhov tseeb, thiab cov chains yuav tsum tsis txhob txuas nrog lub nozzles lossis lwm yam tsis yog - nqa qhov chaw.
8. Tshawb xyuas cov roj Transformer tiav ua ntej xa khoom
Kev tshuaj xyuas zaum kawg yuav tsum paub meej tias ntau dua li cov xim thiab tag nrho qhov ntev. Cov chaw tsim tshuaj paus yuav tsum tshuaj xyuas lub plhaub roundness, npog flatness, interface qhov chaw, weld tsos, txheej thickness thiab cov xwm txheej ntawm txhua lub ntsej muag sealing. Qhov qhib yuav tsum huv si thiab tiv thaiv plua plav lossis dej nkag.
Cov pob khoom xa tuaj yuav tsum suav nrog kev pom zoo kos duab kho, daim ntawv qhia qhov ntev, xau- cov ntaub ntawv xeem thiab cov txiaj ntsig tshuaj ntsuam txheej. Cov ntaub ntawv taug qab tau tshwj xeeb yog qhov muaj txiaj ntsig zoo rau kev xaj rov ua dua hauv ntau pawg.
Tiv thaiv kom tsis txhob xau yuav tsum muaj kev tswj hwm kev tsim khoom ib ntus es tsis yog ib qho kev sim zaum kawg. Kev tsim qauv zoo txo qhov kev ntxhov siab, kev tsim kom raug txhim kho kom haum- nce, vuam ruaj khov tsim cov seams suab, thiab ua tib zoo tuav tiv thaiv kev ua haujlwm tiav lawm.
Nantong Zhihe Electric tsim kev caiib zaug -theem ncej- mounted transformer roj tso tsheb hlau luam raws li cov neeg siv khoom kos duab pom zoo. Txhua lub tank raug tshuaj xyuas qhov ntev thiab xau- kuaj ua ntej txheej txheej. Xa koj daim duab tank rau peb, ntsuas qhov ntsuas hluav taws xob, ntsuas hluav taws xob-kua dej thiab ntsuas ntsuas rau kev tshuaj xyuas kev tsim khoom.
