Thaum nws los txog rau O-rings, muaj ntau yam xim xaiv los ntawm, xws li dub, ntsuab, xiav, thiab liab. Tab sis dab tsi yog qhov txawv ntawm O-ring dub thiab ntsuab O-ring?
Ua ntej, nws tseem ceeb heev uas yuav tsum nco ntsoov tias O-rings yog siv los ua lub foob lossis gasket hauv ntau daim ntawv thov, suav nrog tsheb, kav dej, thiab kev lag luam aerospace. Cov xim ntawm O-ring tuaj yeem qhia txog nws cov khoom muaj pes tsawg leeg, uas tuaj yeem cuam tshuam nws qhov kev ua tau zoo hauv qee qhov chaw.
Dub O-rings feem ntau yog tsim los ntawm Nitrile Butadiene Rubber (NBR), cov roj hmab hluavtaws uas muaj kev tiv thaiv zoo rau roj, roj, thiab tshuaj lom neeg. Cov O-rings no feem ntau siv rau hauv kev siv tsheb, vim lawv tuaj yeem tiv taus qhov hnyav ntawm cov cav thiab cov tshuab roj.
Ntawm qhov tod tes, ntsuab O-rings yog tsim los ntawm Fluorocarbon Roj Hmab (FKM), uas muaj cov tshuaj zoo heev thiab kub tsis kam. Cov O-rings no feem ntau siv nyob rau hauv aerospace thiab tshuaj ua lag luam, qhov twg muaj kub kub thiab hnyav tshuaj.
Nyob rau hauv cov nqe lus ntawm lub cev tsos, dub O-rings feem ntau softer thiab ntau pliable tshaj ntsuab O-rings, uas yog firmer thiab tsis yooj yim sua. Qhov no ua rau ntsuab O-rings zoo dua rau kev sib khi daim ntaub ntawv uas xav tau siab dua thiab ntsuas kub.
Hauv kev xaus, kev xaiv ntawm O-ring dub thiab ntsuab O-ring feem ntau yog nyob ntawm daim ntawv thov tshwj xeeb thiab ib puag ncig nws yuav raug. Kev nkag siab txog qhov sib txawv ntawm ob hom O-rings tuaj yeem pab xyuas kom meej tias lub foob raug xaiv rau txoj haujlwm.
