Txhua tus neeg yuav tsum paub tias O-ring yog cov khoom siv roj hmab ntau heev. Nws tuaj yeem tsis tsuas yog tiv thaiv cov kua hauv nruab nrab ua haujlwm los ntawm kev xau, tab sis kuj tiv thaiv cov plua plav sab nraud thiab cov khoom txawv teb chaws los ntawm kev nkag mus rau hauv kab noj hniav. Yog li dab tsi yog nws cov kev siv tseem ceeb, nws cov kev xav tau rau cov ntaub ntawv yog dab tsi, thiab koj yuav tsum xyuam xim rau thaum khaws cia? Nyob rau hauv teb rau cov teeb meem no, Linde ntsaws ruaj ruaj yuav qhia nws nyob rau hauv kom meej rau koj, yog li ntawd koj muaj peev xwm muaj kev nkag siab meej ntxiv ntawm nws.
Lub hom phiaj tseem ceeb
Thaum lub tshuab ua haujlwm, yuav muaj kev sib txhuam tsis sib xws. Txhawm rau txo qhov kev sib txhuam poob, lubricating roj yuav tsum tau ntxiv thaum lub tshuab ua haujlwm. Txhawm rau tiv thaiv cov roj los ntawm qhov sib txawv ntawm lub tshuab thiab cuam tshuam rau kev siv lub tshuab, nws yog qhov yuav tsum tau siv lub nplhaib sib khi. Nrog rau kev txhim kho thev naus laus zis, cov cuab yeej siv tshuab tau dhau los ua ntau thiab ntau dua. Ntxiv nrog rau cov roj, tej zaum yuav muaj lwm yam kua uas yuav xau, thiab lwm yam impurities kuj tuaj yeem nkag mus rau sab hauv ntawm lub tshuab. Txhawm rau zam cov xwm txheej no, nws yog qhov yuav tsum tau siv lub nplhaib sib khi.
Sealing Material Requirements
Thaum xaiv cov khoom siv, nws yog ib qho tsim nyog yuav tsum xaiv cov khoom siv nrog kev sib khi zoo, kev nyab xeeb thiab kev ntseeg siab, lub neej ntev, tus nqi qis, thiab kev ua haujlwm yooj yim, thiab cov ntaub ntawv tseem yuav tsum tau ua kom zoo sib xws nrog kev ua haujlwm nruab nrab. Txiav txim siab qhov loj ntawm qhov ceev.
Nyob rau hauv luv luv, cov khoom sib khi yuav tsum muaj peev xwm hloov mus rau ntau qhov chaw ua haujlwm kom ua tiav kev sib tw thiab sib npaug.
Lub hom phiaj tseem ceeb, cov khoom siv, thiab kev ceev faj ntawmO-rings
Muaj ntau ntau cov ntaub ntawv siv, ntawm cov roj hmab, hluavtaws cob, hlau, cog fiber ntau thiab tsiaj tawv ntau dua.
Roj hmab yog cov khoom siv dav tshaj plaws hauv kev tsim cov nplhaib sib khi. Nws tuaj yeem muab faib ua cov roj hmab ntuj thiab hluavtaws roj hmab. Ntawm lawv, cov roj hmab hluavtaws tuaj yeem faib ua ntau hom, xws li roj hmab nitrogen, hydrogenated nitrile ruber, hydrogenated nitrile ruber silicone roj hmab, thiab lwm yam.
Kev ceev faj rau kev khaws cia
- Thaum lub nplhaib sealing tsis xav tau ib ntus, nws yog ib qho tsim nyog kom tsis txhob qhib lub pob. Txwv tsis pub, lub nplhaib sealing yog ib qho yooj yim kom tau plua plav, yog li tsis txhob nthuav tawm rau saum huab cua, thiaj li tsis ua kom muaj kev laus.
- Nws raug nquahu kom khaws cia rau hauv ib puag ncig uas tsis muaj av noo, tab sis yuav tsum tau saib xyuas kom tsis txhob muaj tshav ntuj ncaj qha. Tshaj cov av noo thiab ultraviolet rays yuav ua rau nws aging.
- Tsis txhob tso lub nplhaib sib khi ze ntawm qhov chaw kub kub, tshwj xeeb tshaj yog tsis txhob boilers lossis cua sov.
Yog tias txoj kev khaws cia yog tsim nyog, qhov zoo-zoo O-ring feem ntau tuaj yeem khaws cia txog kaum xyoo. Rau lub sij hawm ntev cia ntawm lub nplhaib sealing tsis siv, lub elasticity yuav tsum tau xyuas ua ntej siv los xyuas kom meej tias qhov kev ua tau zoo, thiab qhov saum npoo tsis puas ua ntej nws tuaj yeem siv.
