Ib qho tseem ceeb ntawm lub tshuab nqus tsev vacuum yog lub tshuab nqus tsev vacuum. Cov roj hmab sealing nplhaib, ib qho ntawm nws qhov tseem ceeb, yog qhov tseem ceeb rau kev lav lub valve lub peev xwm kaw.
Elastic O-rings (O-rings)
Ib qho ntawm cov ntsaws ruaj ruaj tshaj plaws rau lub tshuab nqus tsev yog lub elastic O-ring. Nrog nws txoj kab hla hla, nws muaj kev sib khi zoo tshaj plaws ntawm qhov sib txuas ntawm lub valve. Cov khoom siv roj hmab uas feem ntau siv xws li roj hmab silicone (VMQ), fluoroelastomer (FKM), thiab nitrile roj hmab (NBR). Qhov loj me me ntawm O-ring seals feem ntau ua tau raws li cov qauv thoob ntiaj teb, xws li ISO 3601 thiab AS568 (American standard), nyob ntawm qhov xav tau ntawm daim ntawv thov thiab qhov xav tau loj.
Flat gaskets
Hauv seem flange kev twb kev txuas ntawm lub tshuab nqus tsev vacuum, lub nplhaib sealing yog nquag ua haujlwm. Roj hmab lossis roj hmab thiab cov khoom siv hlau sib xyaw, uas muaj kev sib khi zoo thiab kev tiv thaiv corrosion, feem ntau yog siv los ua lawv. ASME B16.21 (American standard) thiab EN 1514 (European standard) yog ob qho piv txwv ntawm cov qauv thoob ntiaj teb uas feem ntau ua raws li qhov loj me ntawm cov nplhaib sib khi.
V-rings
Hauv seem flange kev twb kev txuas ntawm lub tshuab nqus tsev vacuum, lub nplhaib sealing yog nquag ua haujlwm. Roj hmab lossis roj hmab thiab cov khoom siv hlau sib xyaw, uas muaj qhov tshwj xeeb sealing zoo thiab corrosion kuj, feem ntau yog siv los ua lawv. ASME B16.21 (American standard) thiab EN 1514 (European standard) yog ob qho piv txwv ntawm cov txheej txheem thoob ntiaj teb uas feem ntau ua raws li qhov loj me ntawm cov nplhaib sib khi.
Lwm yam tshwj xeeb ntawm cov ntsaws ruaj ruaj
Lwm hom kev sib khi tshwj xeeb, xws li roj hmab diaphragm ntsaws ruaj ruaj lossis piston ntsaws ruaj ruaj, tej zaum yuav xav tau hauv qee qhov tshwj xeeb lub tshuab nqus tsev vacuum. Cov qauv tsim tshwj xeeb thiab kev txiav txim siab ntawm cov chaw tsim khoom feem ntau hais cov qauv thiab qhov loj me rau cov ntsaws ruaj ruaj.
Cov ntsiab lus
Koj lub tshuab nqus tsev vacuum sealing thiab kev ua haujlwm nyob ntawm seb cov roj hmab foob koj xaiv. Txhawm rau lav qhov zoo thiab kev cia siab ntawm lub nplhaib sealing, coj mus rau hauv tus account lub valve txoj kev ua haujlwm, qhov kub thiab txias, qhov xav tau ntawm kev tshaj tawm, thiab lwm yam khoom thaum txiav txim siab ib qho. Koj kuj tuaj yeem sab laj txog cov qauv ntsuas qhov tsim nyog. Linde Polymer muab cov nplhaib sib khi uas ua tau raws li cov qauv kev lag luam, lav lub tshuab nqus tsev ua haujlwm tau zoo.
