Qhov cuam tshuam ntawm kev sib txhuam ntawm O-rings

O-rings yog siv nyob rau hauv ntau yam kav dej, thiab kev sib txhuam yuav inevitably tshwm sim thaum lub tsheb thauj mus los. Kev sib txhuam yuav cuam tshuam li cas rau O-rings?

Hauv kev npaj sealing, kev sib txhuam tuaj yeem ua rau O-rings hnav thiab cuam tshuam rau kev sib khi. Qhov degree ntawm hnav feem ntau nyob ntawm qhov loj ntawm qhov sib txhuam zoo li qub. Thaum cov kua siab me me, qhov sib txhuam loj ntawm O- nplhaib nyob ntawm nws qhov compression shrinkage. Thaum cov kua dej ua haujlwm nyob rau hauv siab, raws li qhov siab ntawm cov kab xa khoom nce, cov kev sib txhuam quab yuam nce. Nyob rau hauv cov ntaub ntawv ntawm kev ua hauj lwm siab tshaj 20MPa, kwv yees li linear kev sib raug zoo. Thaum lub siab ntau dua 20MPa, lub siab ua haujlwm, qhov nce ntawm qhov chaw sib txuas ntawm O- nplhaib thiab cov hlau maj mam qeeb, thiab kev sib txhuam quab yuam yuav nce raws li.

Raws li ib txwm muaj, lub neej kev pab cuam ntawm O-rings yog nruj nrog kev nce siab ntawm hydraulic, thiab lub siab ntawm cov kav xa dej yog tswj nruj heev. Qhov nce ntawm kev sib txhuam thaum lub sij hawm teeb tsa ua rau muaj kev sib txhuam kub ntawm qhov kev sib hloov ntawm kev sib hloov thiab O- nplhaib. Txij li feem ntau O-rings yog ua los ntawm cov khoom siv roj hmab, lawv muaj cov thermal conductivity tsis zoo. Yog li ntawd, kev sib txhuam kub tuaj yeem ua rau cov roj hmab aging, ua rau poob ntawm O- nplhaib foob. Kev sib txhuam kuj tuaj yeem ua rau muaj kev puas tsuaj rau O- nplhaib nto, txo qhov compression. Kev sib txhuam hnyav tuaj yeem ua rau qhov chaw ntawm O- nplhaib, thiab qhov poob ntawm lub foob tuaj yeem cuam tshuam rau kev nyab xeeb ntawm cov kav dej. Yog li kev sib txhuam tuaj yeem cuam tshuam rau O- nplhaib foob.

O-rings haum rau txhua yam ntawm cov cuab yeej siv tshuab, nyob rau hauv qhov ntsuas kub, siab thiab sib txawv kua thiab roj nruab nrab, cov nyhuv sealing hauv lub xeev zoo li qub lossis txav mus. Hauv cov cuab yeej siv tshuab, nkoj, tsheb, khoom siv aerospace, metallurgical machinery, tshuaj machinery, kev tsim kho machinery, siv machinery, mining machinery, roj av machinery, yas machinery, ua liaj ua teb machinery thiab lwm yam twj paj nruag, ib tug loj tus naj npawb ntawm ntau yam ntawm sealing Cheebtsam yog siv. O-rings feem ntau yog siv rau cov khoom zoo li qub thiab sib txuas. Rau cov ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws ntsaws kaw​​ O-rings feem ntau yog ntsia rau ntawm cov ntsaws ruaj ruaj ntawm daim duab plaub -section ntawm lub nplhaib sab nrauv lossis sab hauv. O-rings tseem ua lub luag haujlwm zoo hauv kev sib khi thiab kev poob siab hauv ib puag ncig xws li roj, kua qaub, sib tsoo, thiab tshuaj lom neeg yaig. Yog li ntawd, O-rings yog siv nyob rau hauv feem ntau kaw hydraulic thiab pneumatic kis tau tus mob systems.

Lub nplhaib O- nws muaj nws tus kheej sealing muaj nuj nqi thiab tsis tas yuav tsum tau kho raws sij hawm. Thaum siv rau zawv zawg sealing, qhov sealing kev ua tau zoo tsis tuaj yeem cuam tshuam los ntawm kev txav mus los. Nws yog qhov me me thiab siv tau yooj yim. Vim tias qhov kev hloov pauv loj ntawm lub nplhaib sealing, daim ntawv thov ntawm Qhov ntau yog dav heev, tab sis nws yog ib qho yooj yim rau deform thaum lub siab ncov mus txog ib qho kev siab, thiab nws muaj peev xwm nyem tawm qhov sib txawv. Nws yog dav siv hauv aviation thiab hydraulic engineering.
