Dab tsi yog O-ring

Hauv kev lag luam sealing, O-rings feem ntau siv thiab muaj zog sealing daws. Ib qho ntawm lawv cov txiaj ntsig tseem ceeb yog lawv cov qauv yooj yim thiab tus nqi qis, ua ke nrog kev sib khi zoo thiab kev ntseeg siab, ua rau lawv tau siv dav hauv ntau yam kev lag luam. O-rings feem ntau yog ua los ntawm cov roj hmab (xws li roj hmab nitrile, fluorocarbon roj hmab, silicone roj hmab, thiab lwm yam) los yog lwm yam ntaub ntawv elastic, uas muaj kev hnav zoo, corrosion kuj, thiab kub tsis kam, haum rau ntau yam xov xwm thiab chaw ua haujlwm.

Thaum xaiv qhov tsim nyog O-ring, ntau yam yuav tsum tau txiav txim siab, suav nrog hom kev ua haujlwm nruab nrab (kua, roj), siab, qhov kub thiab txias, tshuaj lom neeg ntawm qhov nruab nrab, thiab ib puag ncig. Kev xaiv O-rings ua los ntawm cov ntaub ntawv tsim nyog ua kom lawv muaj kev sib khi zoo nyob rau hauv ntau yam mob hnyav thiab muaj lub neej ua haujlwm ntev.

Ntxiv rau cov khoom siv roj hmab ib txwm muaj, xyoo tas los no, qee cov ntaub ntawv tshiab xws li fluorocarbon roj hmab (FKM), polytetrafluoroethylene (PTFE), thiab lwm yam, kuj tau siv dav hauv kev tsim cov O-rings. Cov ntaub ntawv no muaj kev tiv thaiv corrosion ntau dua, kub tsis kam, thiab tshuaj lom neeg ruaj khov, haum rau kev xav tau kev ua haujlwm ntau dua.

Yog li ntawd, nyob rau hauv kev lag luam sealing, kev nkag siab txog cov yam ntxwv ntawm cov khoom sib txawv thiab lawv qhov tsim nyog nyob rau hauv kev ua haujlwm sib txawv yog qhov tseem ceeb rau kev xaiv O-rings uas tsim nyog, ua kom muaj kev nyab xeeb thiab kev ua haujlwm zoo ntawm cov khoom siv thiab cov tshuab.
