Valve cover thiab lub tog raj kheej taub hau sealant
Txheem
valve cover sealant ua haujlwm ntawm qhov kub thiab txias, nrog rau kev sib cuag nrog roj. Yog li ntawd, kev xaiv ntawm ib qho los yog lwm txoj kev yuav tsum tau ua raws li qhov tseeb tias lub sealant yuav tsum tsis txhob poob nws cov khoom ua haujlwm hauv cov xwm txheej nyuaj.
Muaj plaub hom kev sealants - aerobic, hardening, mos thiab tshwj xeeb. Hom tom kawg yog qhov zoo tshaj plaws raws li lub valve npog sealant. Raws li rau xim, feem ntau qhov no tsuas yog kev lag luam ploy, txij li cov tuam txhab sib txawv ntawm cov khoom lag luam uas muaj cov yam ntxwv zoo sib xws yuav muaj xim zoo sib xws, thaum sib txawv hauv kev ua haujlwm.
sealant xav tau.
Thaum xaiv ib qho los yog lwm yam cuab yeej, ua ntej ntawm tag nrho cov, koj yuav tsum tau xyuam xim rau nws cov kev ua tau zoo yam ntxwv. Raws li tau hais los saum no, ua ntej ntawm tag nrho cov, koj yuav tsum tau xaiv cov sealant, muaj peev xwm ua haujlwm ntawm qhov kub thiab txias. Yog li ntawd, qhov siab dua qhov kub nws tuaj yeem tiv taus, qhov zoo dua. Qhov no yog qhov tseem ceeb tshaj plaws!
Qhov thib ob tseem ceeb tshaj plaws yog tsis kam mus rau ntau yam txhoj puab heev tshuaj compounds (cov roj cav thiab kis tau tus mob, cov kuab tshuaj, cov kua nres, tshuaj tiv thaiv kab mob thiab lwm yam dej ua haujlwm).
Qhov thib peb yam yog tsis kam rau mechanical stress thiab vibration. Yog tias qhov yuav tsum tau ua tsis tau raws li qhov yuav tsum tau ua, ces lub sealant yuav yooj yim crumble nyob rau hauv lub sij hawm thiab spill tawm ntawm qhov chaw uas nws twb xub nteg.
Qhov thib plaub yog yooj yim ntawm kev siv. Ua ntej tshaj plaws, nws txhawj xeeb txog kev ntim khoom. Nws yuav tsum yooj yim rau tus tswv lub tsheb siv cov khoom siv rau ntawm qhov chaw ua haujlwm. Ntawd yog, nws tsim nyog yuav cov raj me me lossis cov tshuaj tsuag. Qhov kev xaiv tom kawg yog yooj yim dua, thiab feem ntau suav hais tias yog kev tshaj lij, vim nws tau siv los ntawm cov neeg ua haujlwm hauv chaw nres tsheb.
Yog tias koj tsis npaj yuav siv nws nyob txhua qhov chaw uas tsis yog lub hau npog, ces koj yuav tsum tsis txhob yuav lub ntim ntim loj rau koj (feem ntau cov sealants muaj lub neej txee ntawm 24 lub hlis, thiab qhov kub ntawm +5 ° C txog + 25 ° C. C, txawm hais tias cov ntaub ntawv no yuav tsum tau qhia meej hauv cov lus qhia tshwj xeeb).
Thaum siv cov cuab yeej zoo li no, koj yuav tsum nco ntsoov txog cov cuab yeej sib dhos. Qhov tseeb yog tias ntau tus neeg tsim khoom nteg cov khoom sib khi ua ke nrog lub hau npog gasket. Txawm li cas los xij, thaum disassembling lub tshuab hluav taws xob sab hauv (piv txwv li, nws qhov kev kho dua tshiab), tus neeg nyiam tsheb lossis cov kws ua haujlwm ntawm lub chaw pabcuam yuav tsis rov qab siv lub sealant, uas yuav ua rau cov roj to. Lwm qhov laj thawj rau qhov no yog qhov tsis sib haum xeeb hauv kev zawm lub zog ntawm cov mounting bolts.

Lub nuances ntawm kev siv sealant rau valve npog
ib qho ntawm cov npe sealants muaj nws tus yam ntxwv. Raws li, koj yuav pom cov ntaub ntawv tseeb ntawm lawv siv tsuas yog hauv cov lus qhia txuas nrog lub cuab yeej.

Txheej txheem cej luam ntawm Nrov Tshuab High Temperature Sealants
- Lub sealant yog tag nrho vulcanized tom qab tsuas yog ob peb teev.. Koj yuav pom cov ntaub ntawv qhia tseeb hauv cov lus qhia lossis ntawm lub ntim. Raws li, tom qab siv nws, lub tsheb tsis tuaj yeem siv, thiab txawm tias tsuas yog pib lub cav combustion sab hauv ntawm qhov tsis ua haujlwm kom txog rau thaum muaj pes tsawg leeg qhuav tag. Txwv tsis pub, lub sealant yuav tsis ua cov haujlwm uas tau muab rau nws.
- Ua hauj lwm nto ua ntej thov Nws yog ib qho tsim nyog tsis tsuas yog degrease, tab sis kuj yuav tsum ntxuav los ntawm av thiab lwm yam me me. Ntau cov kuab tshuaj (tsis yog ntsuj plig dawb) tuaj yeem siv rau degreasing. Thiab nws yog qhov zoo dua los ntxuav nws nrog txhuam hlau los yog ntawv xuab zeb (nyob ntawm seb qhov kev sib kis thiab cov ntsiab lus yuav tsum tau ntxuav). Qhov tseem ceeb tshaj plaws yog tsis txhob overdo nws.
- Rau reassembly, bolts Nws yog ib advisable kom nruj nrog ib tug torque ciaj ntswj, soj ntsuam ib theem zuj zusmuab los ntawm cov chaw tsim khoom. Ntxiv mus, cov txheej txheem no yog ua nyob rau hauv ob theem - ib tug ua ntej zawm, thiab tom qab ntawd ua tiav ib qho.
- Tus nqi ntawm sealant yuav tsum yog nruab nrab. Yog hais tias muaj ntau ntawm nws, ces thaum nruj, nws tuaj yeem nkag mus rau hauv lub cav combustion, yog tias nws yog me me, ces qhov kev ua haujlwm ntawm nws cov kev siv yog txo mus rau xoom. kuj tsis txhob npog tag nrho saum npoo ntawm gasket sealant!
- Sealant yuav tsum tau muab tso rau hauv qhov zawj ntawm lub hau thiab tos li 10 feeb, thiab tsuas yog tom qab ntawd koj tuaj yeem nruab lub gasket. Cov txheej txheem no muab kev nplij siab ntau dua thiab muaj txiaj ntsig ntawm kev tiv thaiv.
- Yog tias koj siv lub gasket uas tsis yog thawj zaug, nws yog qhov zoo tshaj plaws los siv lub sealant (txawm hais tias tsis tas), vim nws qhov ntev thiab cov duab yuav txawv. Thiab txawm tias qhov sib txawv me ntsis yuav ua rau muaj kev ntxhov siab ntawm lub cev.
Kos koj tus kheej cov lus xaus..
Nws yog nyob ntawm tus neeg tsav tsheb txiav txim siab seb puas yuav siv lub sealant.
