1 cua xau
Nws yog ib qho tsis pom kev. Xws li cov pa tawm hauv thiab tawm ntawm lub taub hau lub taub hau, lub diaphragm ntawm cov roj conservator, iav ntawm txoj kev nyab xeeb, thiab cov hlwv welds.
Cov dej noo thiab cov pa oxygen hauv huab cua yuav maj mam nkag mus rau hauv lub cev los ntawm cov khoom xau, thiab lub foob ntawm sab hauv thiab sab nraud ntawm lub cev.transformeryuav raug puas tsuaj, ua rau muaj teeb meem xws li ya raws nyob rau hauv lub rwb thaiv tsev thiab ceev aging ntawm cov roj.
2 oil to
2.1 Internal to.
Cov roj nyob rau hauv lub bushing los yog cov roj nyob rau hauv lub on-load kais changer chamber leaks rau hauv lub transformer lub cev.
2. 2 External to.
Weld to thiab seal leakage yog cov feem ntau to taub tshwm sim.
Kev tiv thaiv cov roj to hauv cov transformers tshwj xeeb
1 Xaiv cov ntsaws ruaj ruaj nrog cov khoom zoo
Thaum overhauling lub transformer thiab soj ntsuam nrog to, seals nrog zoo kub kuj thiab roj kuj yuav tsum tau xaiv. Cov khoom siv sealing feem ntau siv hauv kev lag luam tshwj xeeb hauv tsev yog cov roj hmab nitrile. Nws cov roj kuj tseem nyob ntawm cov ntsiab lus acrylonitrile hauv cov roj hmab nitrile. Qhov siab dua cov ntsiab lus acrylonitrile, qhov zoo dua cov roj kuj, qhov nyuaj dua, thiab qhov tsawg dua nws yuav deform.
Feem ntau, nitrile roj hmab nrog Shore hardness ntawm 70 thiab 80 yuav tsum tau xaiv. Thaum txheeb xyuas cov roj tsis kam ntawm lub gasket, qhov kev laus ntawm cov gasket thiab qhov kev sib tw nrog cov roj tshwj xeeb transformer feem ntau yuav tsum tau ua. Lub gasket yuav tsum tau muab tso rau hauv cov roj kub ntawm 120 degree rau 168 teev, thiab tom qab ntawd qhov kev hloov pauv ntawm nws qhov hnyav, ntim thiab hardness yuav tsum ntsuas. Xaiv Nws muaj me ntsis deformation thiab ua tau raws li tus qauv seals.
2 Xaiv cov npauj npaim zoo li qub
Raws li tus npauj npaim valve, xaiv ZF80 lub tshuab nqus tsev eccentric npauj npaim valve. Piv nrog rau cov npauj npaim zoo tib yam li qub, lub zog txhua yam thiab qhov chaw tiav ntawm lub tshuab nqus tsev eccentric npauj npaim valve tau zoo heev, thiab qhov zoo tshaj plaws ntawm cov khoom no yog tias nws siv ob txheej txheej sealing ntawm lub interface nrog lub transformer flange, uas tshem tawm cov roj to. teeb meem ntawm transformer interface.
3 Siv hluav taws xob vuam los ntsaws cov xau
Hluav taws xob vuam siv tau los ntsaws lub qhov hws thiab cov hlwv sab laug los ntawm kev nruam ntawm kev hloov pauv tshwj xeeb, nrog rau cov vuam seams thiab cov pob qij txha uas muaj vuam tsis muaj zog, desoldering, thiab tawg.
Qhov taw tes xau yuav tsum raug txheeb xyuas ua ntej ntsaws vuam. Yog tias qhov xau taw tes me me, qhov taw tes xau tuaj yeem raug tua ncaj qha nrog hluav taws xob vuam. Yog hais tias lub qhov dej xau loj dua, txoj hlua asbestos lossis hlau muab tub lim yuav tsum tau ntim ua ntej, thiab tom qab ntawd ntog ib ncig ntawm nws, thiab tom qab ntawd yuav tsum siv lub vuam me me. Ceev arc ignition thiab kho welding nrog high tam sim no.
4 Txheem foob hloov txheej txheem
Rau kev hloov pauv tshwj xeeb ntawm cov qauv sib txawv thiab muaj peev xwm, txawm tias flange kev twb kev txuas lossis threaded kev twb kev txuas yog siv, cov plua plav thiab xeb ntawm qhov chaw sib txuas yuav tsum tau muab tshem tawm ua ntej hloov lub foob. Tom qab ntxuav lub foob, thov sealant rau ntawm ob sab ntawm lub foob. Glue (feem ntau yog siv 609 polymer kua sealant). Tom qab lub sealant dries rau ib lub sij hawm ntawm lub sij hawm thiab cov kuab tshuaj evaporates, zawm lub flange thiab ntsia hlau txuas.
5. Txhim kho qib ntawm kev teeb tsa thev naus laus zis thiab tshem tawm cov xau los ntawm txoj kev teeb tsa tsis raug.
Yog hais tias lub flange interface tsis sib npaug los yog deformed thiab misaligned, kho lub interface ua ntej. Yog hais tias qhov misalignment loj heev thiab kho tsis tau, lub flange yuav raug txiav tawm thiab rov welded. Xyuas kom tseeb tias cov interfaces yog parallel. Thaum lub sij hawm installation, tus nqi compression ntawm lub gasket yog kwv yees li 1/3 ntawm nws thickness.
6 Ceev sealing thiab ntsaws cov nplaum nplaum
Txoj kev no yog siv rau me me xau thiab drips hauv transformers. Txoj kev no tuaj yeem siv los ntsaws cov xau hauv qhov tshwj xeeb transformers qhov twg cov phab ntsa radiator raj yog nyias thiab qhov twg cov ntsiab lus to tsis haum rau vuam ntsaws.
Thaum siv cov nplaum nplaum nplaum los ntsaws cov xau, cov roj, xim, thiab oxides hauv qhov ntsaws yuav tsum tau muab tshem tawm kom cov hlau tuaj yeem pom nws cov xim tiag. Tom qab ntawd kho cov kua nplaum sealing raws li qhov kev faib ua feem thiab kaw qhov to kom txog thaum tsis muaj qhov to.
Cov ntsiab lus
Nrog rau txoj kev loj hlob ntawm kev lag luam transformer, yuav ua li cas los txhim kho cov kev ua tau zoo ntawm cov khoom siv tshwj xeeb transformer thiab xyuas kom meej tias cov kev lag luam txhim khu kev qha ntawm cov transformers tshwj xeeb yog ib qho teeb meem ceev uas yuav tsum tau daws nyob rau hauv transformer ntau lawm. Yog li ntawd, seb qhov teeb meem ntawm cov roj to nyob rau hauv tshwj xeeb transformers yuav daws tau tam sim ntawd thiab kom huv si Nws kuj tau maj mam dhau los ua ib qho tseem ceeb kev taw qhia los ntsuas kev loj hlob ntawm transformer kev lag luam.
