Nruas Kev Them Nyiaj Thiab Thim Cov Roj Hmab O-ring

Kev xaiv ntawm cov compression piv W ntawm cov roj hmab O-ring yuav tsum xav txog kev siv cov xwm txheej, zoo li qub los yog lub cim ruaj khov; zoo li qub foob tau muab faib ua radial foob thiab axial foob; cov qhov khoob khuav ntawm radial foob (lossis cylindrical zoo li qub foob) yog radial Cov kis, qhov khoob khia ntawm axial foob (lossis dav hlau zoo li qub foob) yog qhov tsis txaus axial. Axial cov ntsaws ruaj ruaj tau muab faib ua ob qho xwm txheej sab hauv thiab sab nraud siab raws li seb lub siab nruab nrab ua rau sab hauv lossis txoj kab uas hla ntawm O-ntiv nplhaib. Lub zog sab hauv nce ntxiv qhov ncab, thiab sab nraud kev txo qis thawj zaug kev ncab ntawm O-ring.

Cov. Hauv qhov hais los saum toj no zoo li qub khi, qhov kev coj ua ntawm qhov sib khi nruab nrab ntawm O-ring yog qhov sib txawv, yog li qhov kev ntsuas ua ntej-siab kuj tseem txawv. Rau cov ntsaws ruaj ruaj ruaj, nws yog qhov yuav tsum tau paub qhov txawv ntawm qhov ua kom sib haum cov lus sib dhos thiab cov lus sib dhos tig.

1. Static sealing: Cov twj ntaus sib khi zoo ib yam yog qhov sib npaug ntawm cov khoom sib khi, feem ntau W=1 0% - 1 5%; lub dav hlau zoo li qub sealing khoom W=1 5% -30%.

2. Rau lub cim ruaj khov, nws muaj peev xwm raug faib ua peb kis; reciprocating tsab ntawv tsa suab feem ntau yuav siv W= 10% ~ 15%. Kev sib hloov cov lus pom kev sib hloov yuav tsum xav txog Joule cua sov ua haujlwm thaum xaiv qhov sib piv cua sov. Feem ntau hais lus, txoj kab uas hla ntawm O-ntiv nplhaib rau cov lus qoj ib ce yog 3% -5% loj dua ntawm kab npoo taub, thiab sab nraud taub compression piv W= 3% -8%. Txhawm rau txo qis kev sib txhuam, O-rings siv rau kev sib txhuam tsis tshua muaj zog feem ntau xaiv qhov ntsuas me dua, qhov ntawd yog, W= 5% -8%. Ntxiv rau, qhov kev nthuav tawm cov khoom siv roj hmab tshwm sim los ntawm qhov nruab nrab thiab qhov kub thiab txias kuj yuav tsum raug txiav txim siab. Feem ntau nyob sab nraud qhov muab kev tiv thaiv deformation, qhov tso cai nthuav dav tau ntau yog 15%. Tshaj li cov kab ntawv no qhia tau tias kev xaiv cov khoom siv tsis haum. O-ntiv nplhaib ntawm lwm yam khoom siv yuav tsum siv hloov, lossis tus lej muab pauv hloov deformation yuav tsum tau kho.

Tom qab cov roj hmab O-ntiv nplhaib tau muab tso rau hauv qhov sib khi sealing, nws feem ntau muaj qee qhov nqi ntawm kev ncab. Zoo li qhov ntsuas kev nrawm, qhov nyiaj ntawm kev ncab muaj qhov cuam tshuam zoo rau kev ua haujlwm sealing thiab kev pab cuam lub neej ntawm O-ring. Qhov loj ntawm kev ncab tsis tsuas yog ua rau muaj qhov nyuaj ntawm kev txhim kho O-ntiv nplhaib, tab sis kuj txo qhov kev txu qhov hloov vim qhov hloov ntawm cov kab uas hla ntawm txoj kab uas hla d0, uas ua rau xau.
