O-rings feem ntau yog siv cov khoom sib khi hauv cov tshuab sealing tshuab. Lawv tuaj yeem siv rau ntau yam kev lag luam thiab kev lag luam xws li hydraulics, pneumatics, tsheb, tsheb thauj mus los, khoom siv kho mob, thiab lwm yam.
Yuav xaiv cov khoom siv O-ring li cas? Thaum xaiv cov khoom foob, kev txiav txim siab zoo yuav tsum tau ua raws li qhov sib txawv ntawm ib puag ncig thiab kev xav tau ntawm kev siv. Cov hauv qab no yuav qhia txog kev xaiv cov ntaub ntawv foob raws li elasticity, anti-aging, tshuaj stability, thiab lwm yam.
1. Cov khoom siv elasticity
Lub sealing kev ua tau zoo ntawm lub foob muaj feem xyuam rau nws cov khoom elastic, yog li cov khoom yuav tsum muaj elasticity zoo thiab tuav lub sijhawm ntev elastic rov qab. Cov ntsaws ruaj ruaj zoo yuav xaiv cov khoom siv nrog elasticity zoo li cov khoom tseem ceeb. Feem ntau siv cov ntaub ntawv hauv khw muaj xws li NBR, EPDM, FKM, VMQ, thiab lwm yam.
NBR cov khoom muaj elasticity zoo, siab roj kuj, thiab hnav tsis kam, thiab feem ntau yog siv rau hydraulic roj ntsaws ruaj ruaj thiab refueling khoom foob. Cov khoom siv EPDM kuj muaj qhov elasticity zoo, huab cua tsis zoo, thiab thermal stability, thiab tuaj yeem siv rau kev sib khi xov xwm xws li dej, chav dej, cawv, thiab kua qaub.
FKM cov khoom muaj elasticity zoo, zoo heev kub-resistant, thiab tshuaj stability, thiab yuav siv tau rau high-temperature roj thiab roj foob. VMQ cov khoom muaj elasticity zoo thiab kub-resistant thiab yog haum rau sealing nyob rau hauv high-temperature thiab tsis muaj roj.
2. Anti-aging muaj peev xwm
Thaum siv mus ntev, cov ntsaws ruaj ruaj yuav muaj hnub nyoog nrog kev hloov ntawm ib puag ncig yam xws li kub thiab siab, ua rau txo qis hauv kev sib khi. Thaum xaiv cov ntaub ntawv, nws yog ib qho tsim nyog yuav tau xav txog kev tiv thaiv kev laus thiab kev pab lub neej. Feem ntau, cov ntaub ntawv uas muaj kev tiv thaiv oxidation zoo, tiv thaiv tshav kub, thiab UV kuj raug xaiv. Thaum lub ambient kub yog siab, high-temperature-resistant cov ntaub ntawv xws li FKM tuaj yeem xaiv.
3. Tshuaj stability
Txij li cov ntsaws ruaj ruaj yuav tsum tau siv nyob rau hauv ntau yam xov xwm, lawv cov tshuaj stability yuav tsum tau xav txog. Feem ntau, cov ntaub ntawv uas muaj roj zoo, acid tsis kam, thiab alkali tsis kam raug xaiv los xyuas kom meej tias lawv tuaj yeem tuav tau zoo sealing kev ua tau zoo hauv cov xov xwm sib txawv.
NBR cov ntaub ntawv muaj cov roj ua haujlwm zoo thiab tuaj yeem siv rau cov roj tuav cov nplhaib thiab cov dej tuav cov nplhaib hauv cov tshuab foob. FKM cov ntaub ntawv muaj cov tshuaj tiv thaiv zoo thiab hnyav hnyav thiab feem ntau siv hauv tshuaj, tshuaj, thiab lwm yam haujlwm.
Hauv cov ntsiab lus, kev xaiv cov ntaub ntawv O-ring yuav tsum xav txog ntau yam xws li cov khoom siv elasticity, muaj peev xwm tiv thaiv kev laus, thiab tshuaj lom neeg ruaj khov. Kev xaiv cov khoom siv zoo tuaj yeem ua kom muaj kev sib khi zoo heev thiab kev pabcuam lub neej nyob rau hauv ib puag ncig sib txawv, kom ua tau zoo dua rau cov kev xav tau ntawm ntau daim ntawv thov.
