Piv nrog rau lwm hom sealing nplhaib, O-ring muaj qhov zoo hauv qab no:
1, haum rau ntau hom sealing: sealing zoo li qub, dynamic sealing, haum rau txhua yam ntaub ntawv, qhov loj thiab qhov zawj tau raug qauv, muaj zog sib hloov.
2. Haum rau ntau hom kev txav chaw: cov lus tsa suab, axial reciprocating motion lossis ua ke (xws li teb reciprocating ua ke motion).
3, haum rau ntau yam sib txawv sealing media: roj, dej, roj, tshuaj lom neeg los yog lwm yam khoom sib xyaw. Los ntawm kev xaiv cov khoom siv roj hmab tsim nyog thiab tsim qauv tsim, kom ua tiav cov txiaj ntsig zoo ntawm cov roj, dej, cua, roj thiab ntau yam tshuaj lom neeg. Qhov ntsuas kub yog qhov dav (-60 degree ~ ntxiv rau 220 degree), thiab lub siab tuaj yeem ncav cuag 1500Kg / cm2 thaum siv tas (ua ke nrog lub nplhaib txhawb nqa).
4, yooj yim tsim, compact qauv, yooj yim installation thiab disassembly. O-ring seem qauv yog yooj yim heev, thiab muaj cov nyhuv ntawm tus kheej sealing, sealing kev ua tau zoo yog txhim khu kev qha. Vim tias O-ring nws tus kheej thiab cov qauv ntawm qhov chaw teeb tsa yog qhov yooj yim heev, thiab tau ua tus qauv, yog li kev teeb tsa thiab hloov pauv tau yooj yim heev.
5, ntau yam khoom siv. Muaj peev xwm xaiv tau raws li cov kua dej sib txawv: butadiene roj hmab (NBR), fluorine roj hmab (FKM), silicone roj hmab (VMQ), ethylene propylene roj hmab (EPDM), neoprene roj hmab (CR), butyl roj hmab (BU), polytetrafluoroethylene (PTFE), natural rubber (NR) thiab lwm yam.
6. Tus nqi qis.
7, dynamic kev sib txhuam kuj yog me me.
