Muaj nuj nqi
O-rings raug kaw cov voj voos ncig ntawm cov voj voos sib tshooj. Lawv tau ua los ntawm vulcanisation los ntawm cov cuab yeej siv ua lub nplhaib tiav. Kev ua haujlwm ntawm O-ntiv nplhaib tau ua tiav los ntawm kev deformation ntawm qhov chaw hla thaum muab ntsia thiab ua kom tiav hauv nws lub tsev. O-ring tuaj yeem ua kom nrawm radially lossis axially nyob hauv nws cov tsev teeb tsa. Hauv kev ua haujlwm ntawm lub siab ua haujlwm tshaj tawm los ntawm kev tshaj tawm xov xwm ntxiv dag zog rau kev ua haujlwm sealing, raws li hauv siab ntawm elastomer cov khoom ua haujlwm raws li cov kua dej tsis tau yooj yim.

Cov ntawv thov
O-rings yog siv feem ntau rau kev sib khi lub tshuab tsis txav thiab lub cev (cov ntawv thov zoo li qub) thiab xov xwm ua kua thiab roj, piv txwv li flange thiab npog cov ntsaws ruaj ruaj, xov txuas raj thiab lub tog raj kheej taub thiab lub tog raj kheej hauv qab rau hydraulic lub tog raj kheej. Hauv qee qhov xwm txheej nws kuj tseem tuaj yeem siv O-rings nrog reciprocating, sib hloov thiab helical txav (thov tau zoo). Yog tias lub tsev teeb tsa tau ua tiav qhov tseeb, qhov kev tsim ua yog tsim nyog thiab cov ntaub ntawv raug xaiv, nws muaj peev xwm ua kom cov nias txog li ntawm 1000 bar tau raug muab khi, nrog rau siv cov ntiv nplhaib rov qab, qhov uas yuav tsum tau ua. O-rings yog siv ntau hauv cov haujlwm, xws li kev ua liaj ua teb, pneumatics, kev siv lub tshuab nqus tsev, kev lag luam fittings, kev lag luam tsheb thiab hauv kev cog ntoo thiab kev siv tshuab.

Teeb tsev
Kev teeb tsa cov tsev nyob (grooves) rau O-rings yuav tsum yog ua tau nrog tsim txoj cai ces kaum thiab yuav tsum ua nrog kev saib xyuas. Yuav tsum zam, kev kub nyhiab, khawb thiab ntiv taw. Lub qhov ntev rau qhov xav tau qhov tob thiab qhov dav ntawm qhov zawj yog nyob ntawm cov ntawv thov tshwj xeeb thiab ntu ntu. Koj yuav pom cov lus pom zoo rau kev tsim kho thiab cov lus pom dav hauv peb O-Ring Catalog. Txhawm rau kom yooj yim rau kev teeb tsa, ntau yam txheej txheej saum npoo tuaj yeem muab rau ntawm daim ntawv thov.

Xaiv thiab qauv
Txhawm rau kom muaj lub suab sib khi, O-rings yuav tsum raug xaiv los txhawm rau muaj qhov loj tshaj plaws tau hla kev hla. Lub hardness ntawm O-ring cov khoom siv xaiv nyob ntawm lub siab, qhov dav dav, hom ntawm kev sib khi (zoo li qub / dynamic) thiab thaj chaw zoo ntawm cov khoom siv hauv tshuab. Rau cov ntawv thov txheem peb pom zoo kom cov khoom siv tawv ntawm 70 Ntug Dej A. Kev ua tib zoo saib xyuas kuj yuav tsum tau muab rau qhov tseeb compression, elongation lossis compaction thiab qib uas qhov zawj hauv cov teeb tsa tsev.

Muaj qhov haum rau cov xov xwm tshwj xeeb
EPDM
Kev ua tau zoo rau cov dej kub thiab ncu, tshuaj ntxhua khaub ncaws, cov roj zoo nkauj daws teeb meem, cov roj silicone thiab roj, ntau cov tshuaj tiv thaiv polar, thiab ntau cov kua qaub thiab tshuaj lom neeg, nrog rau qib siab ntawm ozone tsis kam. Cov khoom siv EPDM yog qhov tsis tsim nyog rau siv nrog txhua cov khoom siv roj ntxhia (roj, roj).
