Qhia
O-rings yog cov khoom sib khi uas tau siv dav hauv ntau yam kev lag luam thiab cov khoom siv los lav qhov kev sib khi ua haujlwm ntawm kev sib txuas. Cov cuab yeej muaj kev cia siab thiab kev nyab xeeb yog nyob ze rau qhov tseeb ntawm O-ring foob tsim. Cov ntawv tshaj tawm no yuav dhau mus dhau cov tswv yim tseem ceeb, cov teeb meem raug, thiab kho O-ring foob tsim.
Lub hauv paus ntsiab lus
Xaiv cov khoom siv O-ring zoo
Qhov chaw ua haujlwm kub, siab, tshuaj pleev ib ce, thiab lwm yam yuav tsum tau muab coj los txiav txim siab thaum xaiv O-ring cov khoom. Piv txwv li, silicone roj hmab (VMQ) ua haujlwm zoo hauv qhov kub thiab txias, nitrile roj hmab (NBR) hauv cov roj thiab roj av, thiab fluorine roj hmab (FKM) hauv kev siv tshuaj lom neeg.
Txiav txim siab qhov loj me
Lub sealing chamber thiab mating pieces yuav tsum yog tib yam li O-ring. O-rings loj heev los yog undersized tsis tuaj yeem muab kev sib khi ua tau zoo. O-ring diameters feem ntau yog txiav txim siab raws li lub teb chaws lossis thoob ntiaj teb cov qauv (xws li ISO 3601).
Xav txog qhov yooj yim ntawm installation thiab tshem tawm
Cov txheej txheem rau kev txhim kho thiab tshem tawm O-ring yuav tsum raug coj mus rau hauv tus account thaum tsim. Txhawm rau tiv thaiv O-ring kev puas tsuaj thaum lub sijhawm teeb tsa, tus tsim yuav tsum ua kom yooj yim rau nruab. Ib txhij, qhov yooj yim ntawm kev hloov O-ring thaum tsim nyog yuav tsum tau coj mus rau hauv tus account.
Xyuas kom txaus compression
O-ring lub peev xwm kaw tau yog nyob ntawm seb nws compressed li cas tom qab kev teeb tsa. Txhawm rau tsim cov foob zoo, tus tsim yuav tsum lav tias O-ring muaj txaus compression deformation tom qab kev teeb tsa. Ntawm qhov tod tes, compression hnyav yuav ua rau O-ring lub neej luv luv los ntawm kev ua kom deformation ntau dhau.
Cov lus nug nquag nug thiab kev daws teeb meem
O-ring hardened los yog deformed
Cov khoom siv tsis raug siv lossis ib puag ncig uas dhau ntawm O-ring qhov kev ua siab ntev yuav yog qhov ua rau.
Kev daws: Xyuas kom tseeb tias cov xwm txheej ua haujlwm nyob rau hauv O-ring lub siab ntev thiab xaiv cov khoom tsim nyog rau qhov chaw ua haujlwm tshwj xeeb.
Leak teeb meem
Nws yog qhov ua tau rau cov dej xau los ntawm kev ua tsis tiav O-rings, compression tsis txaus, lossis kev teeb tsa tsis zoo.
Kev daws: Txheeb xyuas O-ring qhov loj thiab compression kom paub tseeb tias nws tau teeb tsa kom raug, thiab hloov nws nrog O-ring tsim nyog yog tias xav tau.
O-ring hnav
O-ring hnav yuav tshwm sim los ntawm kev ua haujlwm nyuaj lossis siv txuas ntxiv.
Kev daws: Siv cov khoom siv nrog kev hnav siab dua, suav nrog cov ceramic lossis hlau-coated O-rings, thiab xyuas thiab hloov lawv ua ntu zus.
Twist los yog twist so
O-rings uas twist thaum lub sij hawm dynamic sealing yog raug rau kev tawg.
Kev daws: Siv tus qauv tsim O-ring zoo dua rau cov ntawv thov dynamic, los yog ua kom zoo tshaj qhov tsim los tiv thaiv O-ring distortion thaum txav mus los.
Hauv kev xaus
Kev ruaj ntseg sealing kev ua tau zoo ntawm cov cuab yeej siv khoom siv feem ntau yog nyob ntawm tus qauv tsim ntawm O-ring seals. Cov cuab yeej sealing kev ua tau zoo thiab kev cia siab tuaj yeem txhim kho tau zoo los ntawm kev xaiv cov ntaub ntawv raug, txheeb xyuas cov kev ntsuas, kev teeb tsa thiab disassembly yooj yim rau hauv tus account, thiab xyuas kom meej tias muaj compression txaus. Tsis tas li ntawd, O-ring kev pabcuam lub neej tuaj yeem nce ntxiv, cov nqi kho mob tuaj yeem txo qis, thiab tag nrho cov khoom lag luam tuaj yeem raug tsa los ntawm kev paub thiab daws cov teeb meem sib khi tsis tu ncua.
