Dab tsi yog cov khoom siv zoo tshaj plaws rau o-rings?
Kev xaiv ntawm cov khoom siv O-ring feem ntau yog nyob ntawm daim ntawv thov qhov chaw ib puag ncig, kev ua haujlwm kub, kev xav tau siab, thiab hom kua dej yuav tsum tau kaw. Nov yog qee yam khoom siv O-ring thiab cov xwm txheej tshwj xeeb uas lawv tsim nyog rau:
Nitrile (NBR):
Qhov zoo: Roj-resistant, hnav-tiv taus, qis nqi.
Cov xwm txheej siv tau: Kev siv dav dav, tshwj xeeb tshaj yog nyob rau hauv cov roj lubricating, roj thiab ntau lwm qhov chaw ua kua.
Fluorocarbon (Viton):
Qhov zoo: Kub kub tsis kam thiab tshuaj corrosion kuj.
Cov xwm txheej siv tau: Kub kub thiab tshuaj lom neeg corrosive ib puag ncig, xws li lubricants, fuels, qee cov kua qaub thiab cov kuab tshuaj.
Ethylene Propylene Diene Monomer (EPDM):
Qhov zoo: Resistant ozone, huab cua, dej, acid thiab alkali.
Cov xwm txheej muaj feem xyuam: kev siv sab nraum zoov, kev kho dej, ib puag ncig coolant.
Silicone:
Qhov zoo: Kub kub tsis kam, ozone tsis kam, qib zaub mov.
Muaj cov xwm txheej: qhov kub thiab txias ib puag ncig, khoom noj khoom haus thiab kev siv kho mob.
Polyurethane (PU):
Qhov zoo: Resistant hnav, roj thiab cov kuab tshuaj.
Cov xwm txheej siv tau: Kev hnav khaub ncaws hnyav, lub tshuab hydraulic, thiab lub sijhawm uas yuav tsum muaj kev sib khi siab.
Perfluoroelastomer (FFKM):
Qhov zoo: tiv taus qhov kub thiab txias thiab tshuaj lom neeg corrosion, muab kev sib khi zoo heev.
Cov xwm txheej siv tau: Kub kub, siab siab, thiab cov tshuaj lom neeg muaj zog heev.
Xaiv cov khoom siv O-ring uas tsim nyog tshaj plaws yuav tsum xav txog cov kev ua haujlwm tshwj xeeb. Yog tias koj tsis paub meej, nws yog qhov zoo tshaj plaws los sab laj nrog koj tus neeg muag khoom O-ring lossis cov chaw tsim khoom rau kev tawm tswv yim ntawm kev xaiv cov khoom. Tsis tas li ntawd, xyuas kom meej tias O-ring ua tau raws li cov qauv thiab cov kev qhia tshwj xeeb kom ntseeg tau tias nws qhov kev ua tau zoo thiab kev ntseeg tau.
