O-rings are widely used in life, such as home appliances, automobiles, fire-fighting pharmaceuticals, etc. Especially compared with other forms of sealing rings, it has more advantages. Let's take a look at it below.
Piv nrog rau lwm hom sealing nplhaib, O-rings muaj qhov zoo hauv qab no:
1. Haum rau ntau hom kev sib khi: sealing zoo li qub, dynamic sealing, haum rau ntau yam ntaub ntawv, qhov ntev thiab cov grooves tau raug standardized, muaj zog interchangeability.
2. Haum rau ntau hom kev txav chaw: cov lus tsa suab, axial reciprocating motion, los yog ua ke cov lus tsa suab (xws li cov lus teb reciprocating ua ke).
3. Haum rau ntau yam sib txawv sealing media: roj, dej, roj, tshuaj lom neeg, lossis lwm yam khoom siv sib xyaw. Los ntawm kev xaiv cov khoom siv roj hmab tsim nyog thiab tsim qauv tsim, kev sib khi zoo ntawm cov roj, dej, cua, roj, thiab ntau yam tshuaj lom neeg tuaj yeem ua tiav. Qhov ntsuas kub yog qhov dav (-60 degree ntxiv rau 220 degree), thiab lub siab tuaj yeem ncav cuag 1500Kg / cm2 hauv kev siv tas li (siv ua ke nrog lub nplhaib txhawb nqa).
4. Yooj yim tsim, compact qauv, yooj yim sib dhos, thiab disassembly. Tus ntoo khaub lig-sectional qauv ntawm O- nplhaib foob yog qhov yooj yim heev, thiab nws muaj tus kheej- sealing muaj nuj nqi thiab txhim khu kev qha sealing kev ua tau zoo. Txij li thaum O- nplhaib nws tus kheej thiab cov qauv ntawm qhov chaw teeb tsa yog qhov yooj yim heev thiab tus qauv, nws yooj yim heev rau nruab thiab hloov.
5. Muaj ntau yam khoom siv. Muaj peev xwm xaiv tau raws li cov kua sib txawv: nitrile 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) , poly Tetrafluoroethylene (PTFE), Ntuj Roj Hmab (NR), thiab lwm yam.
6. Tus nqi qis
7. Cov kev sib txhuam dynamic kuj yog me me
Xaiv lub nplhaib sealing zoo yog ib kauj ruam tseem ceeb. O-rings tuaj yeem hloov mus rau feem ntau ib puag ncig thiab muaj txiaj ntsig zoo rau lawv tus kheej.
