Kab lus no yog hais txog lub tshuab foob. Rau lwm yam kev siv, saib Oring.
Hom O-ring thiab daim ntawv thov
IbO-ring, kuj hu ua antimlos yog atoric sib, yog ib tug neeg kho tshuab gasket nyob rau hauv cov duab ntawm ib tug torus; nws yog ib lub voj ntawm elastomer nrog ib puag ncig cross-section, tsim los zaum hauv qhov zawj thiab compressed thaum sib dhos ntawm ob lossis ntau qhov chaw, tsim lub foob ntawm lub interface.
O-ring tuaj yeem siv rau hauv daim ntawv thov zoo li qub lossis hauv cov ntawv thov dynamic uas muaj kev sib txheeb ntawm cov khoom thiab O-ring. Dynamic piv txwv muaj xws li rotating twj shafts thiab hydraulic lub tog raj kheej pistons. Cov ntawv thov zoo li qub ntawm O-rings tuaj yeem suav nrog cov kua dej lossis roj sealing daim ntawv thov uas:
(1) O-ring yog compressed ua rau xoom clearance,
(2) cov khoom siv O-ring yog vulcanized khoom xws li nws yog impermeable rau cov kua los yog roj, thiab
(3) Cov khoom siv O-ring tiv taus degradation los ntawm cov kua lossis roj.
Qhov ntau yam muaj peev xwm ua kua thiab roj uas yuav tsum tau muab ntim tau tsim nyog rau kev txhim kho ntau yam ntawm cov ntaub ntawv O-ring.[2]
