1. Qhov chaw ntawm lub sealing nto: Cov duab thiab qhov roughness ntawm lub sealing nto muaj qee yam cuam tshuam rau kev ua haujlwm sealing. Ib tug du nto yog zoo rau sealing. Mos gaskets tsis rhiab rau saum npoo av vim tias lawv tau yooj yim deformed, thaum lub ntsej muag muaj feem cuam tshuam rau cov tawv tawv.
2. Sib cuag Dav ntawm Sealing Surface: Qhov loj dua qhov dav ntawm qhov sib txuas ntawm qhov sib khi thiab lub gasket los yog ntim, qhov ntev ntawm txoj kev xav tau rau cov dej xau, thiab qhov ntau dua qhov ntws tsis kam, yog li muaj txiaj ntsig zoo rau lub foob. Txawm li cas los xij, nyob rau hauv tib lub zog clamping, qhov sib cuag loj dua yuav txo qhov kev sib khi tshwj xeeb. Yog li ntawd, ib qho kev sib cuag uas tsim nyog yuav tsum tau nrhiav raws li cov khoom ntawm cov khoom sib khi.
3. Cov khoom ntawm Sealing Fluid: Lub viscosity ntawm cov kua muaj qhov cuam tshuam loj rau kev sib khi ua haujlwm ntawm kev ntim khoom thiab gaskets. Cov kua dej uas muaj viscosity siab yog yooj yim dua los kaw vim lawv cov dej tsis zoo. Lub viscosity ntawm cov kua yog ntau dua li cov pa roj carbon monoxide, yog li cov kua nplaum yooj yim dua li cov pa roj. Saturated vapor yog yooj yim dua rau seal dua superheated vapor vim nws condenses rau hauv cov tee dej uas thaiv cov xau channel ntawm qhov chaw sealing. Qhov loj dua qhov ntim ntawm cov kua dej, qhov yooj yim dua nws yuav tsum tau thaiv los ntawm qhov khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob. Lub wettability ntawm cov kua rau cov khoom sealing kuj cuam tshuam rau lub foob. Ib qho yooj yim wetted kua yog feem ntau to to vim capillary ua nyob rau hauv lub micropores ntawm lub gasket thiab ntim.
4. Qhov kub thiab txias ntawm cov kua sealing: Kub muaj feem xyuam rau cov viscosity ntawm cov kua, yog li cuam tshuam cov sealing kev ua tau zoo. Qhov kub nce ntxiv txo cov kua viscosity thiab nce roj viscosity. Tsis tas li ntawd, qhov kub thiab txias hloov feem ntau ua rau deformation ntawm sealing Cheebtsam, ua rau lawv yooj yim rau to.
5. Cov khoom siv ntawm lub sealing gasket thiab ntim khoom: cov ntaub ntawv mos muaj peev xwm ua rau muaj kev ywj pheej los yog cov yas deformation nyob rau hauv preload, yog li thaiv cov dej xau thiab txhawb kev sib khi; Txawm li cas los xij, cov ntaub ntawv mos feem ntau tsis tuaj yeem tiv taus siab - cov kua dej siab. Kev tiv thaiv corrosion, tiv thaiv tshav kub, ntom ntom, thiab hydrophilicity ntawm cov khoom sib khi tag nrho muaj qee yam cuam tshuam rau lub foob.
6. Sealing nto tshwj xeeb siab: Lub zog ib txwm nyob rau hauv ib chav sib cuag ntawm qhov chaw sealing yog hu ua lub sealing tshwj xeeb siab. Qhov loj ntawm qhov sealing nto qhov tshwj xeeb siab yog qhov tseem ceeb cuam tshuam rau kev ua haujlwm sealing ntawm gaskets lossis packings. Feem ntau, ib qho tshwj xeeb tshwj xeeb yog tsim rau ntawm qhov chaw sib khi los ntawm kev siv lub tshuab ua ntej, ua rau lub foob kom deform thiab txo lossis tshem tawm qhov sib txawv ntawm qhov sib txuas ntawm qhov sib txuas, yog li tiv thaiv cov dej ntws thiab ua tiav lub foob. Nws yuav tsum raug sau tseg tias cov kua dej ua rau muaj kev hloov pauv ntawm qhov tshwj xeeb siab ntawm lub sealing nto. Thaum qhov nce ntawm qhov tshwj xeeb siab ntawm qhov sealing nto yog qhov zoo rau kev sib khi, nws raug txwv los ntawm lub zog compressive ntawm cov khoom sealing; rau cov ntsaws ruaj ruaj ruaj khov, qhov nce hauv qhov tshwj xeeb ntawm qhov sealing nto kuj yuav ua rau muaj qhov sib npaug ntawm kev sib txhuam.
7. Cov khoom siv sab nraud cuam tshuam rau lub foob: kev co ntawm cov kav dej, deformation ntawm cov khoom sib txuas, thiab kev ua haujlwm tsis zoo ntawm qhov kev teeb tsa tuaj yeem ua rau tag nrho cov quab yuam ntxiv ntawm lub foob, yog li cuam tshuam rau lub foob. Kev vibration, tshwj xeeb, yuav ua rau lub sijhawm hloov pauv ntawm lub zog clamping ntawm qhov chaw sib khi, loosening cov bolts txuas thiab ua rau lub foob tsis ua haujlwm. Qhov ua rau muaj kev vibration tuaj yeem yog sab nraud lossis vim muaj dej txav hauv lub cev. Txhawm rau kom muaj kev ruaj ntseg foob, tag nrho cov saum toj no yuav tsum tau ua tib zoo txiav txim siab, thiab kev tsim thiab xaiv cov gaskets thiab ntim khoom yog qhov tseem ceeb.
