Ib qho tseem ceeb roj hmab tivthaiv rau sealing pob qij txha yog O-ring. Rau cov cuab yeej siv tshuab ua haujlwm kom zoo, nws yog qhov tseem ceeb uas nws yuav tsum tau nruab thiab tsim kom raug. Xaiv qhov kev cuam tshuam zoo yog qhov tseem ceeb. Qhov tsis pub leejtwg paub txog kev tswj xyuas qhov ua haujlwm zoo ntawm cov khoom siv tshuab thiab cov cuab yeej siv yog txiav txim siab txog qib kev cuam tshuam. Qhov chaw nruab nrab ntawm ob daim yog hu ua "kev cuam tshuam." Qhov chaw no tuaj yeem muab qhov nruj nruj thiab qhov ua tau zoo tshaj plaws ntawm kev sib khi rau lub nplhaib sealing.
Cov khoom siv, ib puag ncig ib puag ncig, thiab qhov tsim nyog ntawm kev sib khi yuav tsum tau muab coj los rau hauv tus account thaum xam cuam tshuam. Feem ntau, txoj kab uas hla, hardness, thiab cov khoom yam ntxwv ntawm lub nplhaib sealing txiav txim siab qhov zoo tshaj plaws ntawm kev cuam tshuam. Cov nyhuv sealing zoo tuaj yeem ua tiav los ntawm kev ua kom lub nplhaib sealing nyob twj ywm nyem tom qab kev teeb tsa nrog qhov kev cuam tshuam zoo.
Qhov zoo ntawm kev cuam tshuam yuav tsum tuav lub sealing nyhuv yam tsis tas yuav compressing O-ring ntau dhau, vim qhov no yuav ua rau lub nplhaib sealing lub neej ua haujlwm luv lossis ua rau muaj kev puas tsuaj thaum ntxov. Kev cuam tshuam theem feem ntau yog nyob rau hauv thaj tsam ntawm 5% mus rau 25%. Cov kab no tuaj yeem hloov pauv kom haum raws li qhov xav tau ntawm daim ntawv thov tshwj xeeb.
Kev xaiv tus nqi tsim nyog ntawm kev cuam tshuam yuav tsum xav txog cov hauv qab no:
- Cov khoom siv ntawm lub nplhaib foob: Tej zaum yuav muaj qhov txawv ntawm qhov cuam tshuam rau kev sib khi lub nplhaib ua los ntawm ntau yam ntaub ntawv. Kev txiav txim siab txog qib ntawm kev cuam tshuam yog li yuav tsum muaj kev nkag siab ntawm cov khoom deformation ntawm cov khoom xaiv. Txhawm rau lav qhov kev foob ua tiav, qee cov ntaub ntawv tuaj yeem xav tau kev cuam tshuam ntau dua, thaum lwm tus yuav xav tau kev cuam tshuam tsawg dua kom tau txais cov txiaj ntsig zoo ib yam.
- Kev ua haujlwm ib puag ncig: Muab rau hauv tus account O-ring qhov ib puag ncig ib puag ncig, suav nrog kev hloov pauv ntawm qhov kub, siab, thiab tshuaj lom neeg. Kev cuam tshuam ntau dua yog xav tau nyob rau hauv high-temperature lossis high-pressure ib puag ncig los tswj cov khoom nthuav dav thiab deformation. Yuav kom nrhiav tau qhov kev cuam tshuam ntawm txoj cai, yuav tsum muaj kev sim thiab xaiv ntau dua nyob rau hauv qhov kub thiab txias.
- Daim ntawv thov yuav tsum tau: Tsim kom muaj kev ua tau zoo thiab sealing qib yuav tsum tau. Txhawm rau tsim qhov tsim nyog foob, qee daim ntawv thov tuaj yeem xav tau kev cuam tshuam ntau dua thiab ua haujlwm zoo dua sealing.
- Installation: Txhawm rau kom muaj kev cuam tshuam tsim nyog, kev teeb tsa kom raug yog qhov tseem ceeb. Ceev faj tsis txhob ua kom lub nplhaib sealing puas thaum lub sij hawm installation, thiab xyuas kom tseeb tias nws compresses kom raug los tsim ib lub foob.
Kev sim thiab kev sim yog qhia thaum xaiv qhov muaj nuj nqis ntawm kev cuam tshuam kom paub tseeb tias nws yuav ua tau raws li qhov xav tau ntawm kev sib khi. Tib lub sijhawm, tshuaj xyuas lub nplhaib sib khi rau kev hnav thiab kev puas tsuaj tsis tu ncua kom ntseeg tau tias nws raug hloov raws sijhawm thiab cov khoom siv txuas ntxiv ua haujlwm kom zoo.
Feem ntau hais lus, qhov zoo ntawm kev cuam tshuam yog los tiv thaiv O-ring los ntawm compressed ntau dhau thaum tuav cov nyhuv sealing, uas ua kom muaj kev ua haujlwm tsis tu ncua ntawm cov khoom siv thiab cov khoom siv. Nyob ntawm seb qhov yuav tsum tau ua ntawm daim ntawv thov tshwj xeeb, xaiv qhov muaj nuj nqis ntawm kev cuam tshuam yuav xav tau kev sim thiab hloov kho ntxiv rau kev coj mus rau hauv tus lej ntawm lwm yam.
