Kev xaiv ntawm O-ring

O-rings tau siv dav hauv ntau qhov kev lag luam thiab tau ua rau ntau tus qauv. Cov qauv siv feem ntau yog AS568, GB3452.

AS568 yog Society of Automotive Engineers (SAE) Aerospace Size Standard rau o-rings. Lub hom phiaj ntawm lub hom phiaj ntawm O-ring specifications yog qhia rau hauv cov kab uas hla, hla ntu, kev kam rau siab, thiab kev txheeb xyuas qhov loj me (dash naj npawb). Ib lub metric o-ring txhais tau hais tias qhov loj ntawm O-nplhaib yog txhais hauv millimeters. Ntxiv rau qhov muaj peev xwm tsim peb tus kheej pwm, Xlong Seals muaj peev xwm tsim O-Rings raws li cov qauv sib txawv.

Cov ntaub ntawv O-ring feem ntau suav nrog Nitrile Butadiene Roj Hmab (NBR), Hydrogenated Nitrile Rubber (HNBR), Fluoroelastomer (FKM), Silicone Rubber (VQM), Ethylene Propylene Diene Monomer (EPDM), thiab lwm yam. Cov ntaub ntawv sib txawv muaj qhov sib txawv ntawm kev ua haujlwm. mus rau kub, ozone, roj, acid thiab alkali hnyav thiab hnav. Cov ntaub ntawv sib txawv O-ring zoo tagnrho rau kev lag luam sib txawv, kev ua haujlwm, thiab kev siv nyiaj txiag. Xlong Seal muaj peev xwm muab cov khoom siv tau thiab pheej yig raws li koj xav tau.
