Cov xwm txheej dab tsi tuaj yeem cuam tshuam kev ua tau zoo ntawm O-Rings

Hardness ntawm o-ntiv nplhaib: lub hardness ntawm o-ring cov khoom yog qhov taw qhia tseem ceeb tshaj plaws rau kev ntsuas cov khoom lag luam. Lub hardness ntawm O-RET txiav txim siab lub compression ntawm O-Ring thiab qhov siab tshaj plaws tso cai rau kev zam ntawm cov zawj.
O-ntiv nplhaib extrusion tshem tawm: qhov siab tshaj plaws pub rau extrusion clearance thiab system siab yog cuam tshuam nrog o-ntiv nplhaib hla kev thiab cov khoom tawv. Feem ntau, qhov siab dua cov haujlwm siab ua haujlwm, qhov me tshaj qhov uas tau tso cai tshaj plaws uas tsis muaj nuj nqis. Yog tias qhov sib txawv tshaj qhov tau muaj ntau yam, nws yuav ua rau O-Ring mus rau Extrude lossis txawm tias puas lawm.
Kev ntsuas hluavtaws ua tiav nrog: Lwm qhov ntsuas kom ntsuas kev sib khi ua haujlwm ntawm O-Ringsing deformation ntawm cov khoom uas tau xaiv. Nyob rau hauv siab, o-ntiv nplhaib, raws li ib tug elastic amominity deformation, thiab raws li lub siab nce, muaj peev xwm ua tau zoo li lwm yam.
O-Ring ua ntej nias tus nqi: Thaum lub O-Ring raug teeb tsa hauv qhov zawj, qhov kev pib ua ntej yuav tsum tau tshwj tseg kom nws tau kev sib khi ua tau zoo. Txog kev thov sib txawv ntawm cov xwm txheej sib txawv, lub Pre ​​Compression shrinkage kev sib tw rau tus ntoo khaublig-seem ntawm cover w kuj txawv. Feem ntau, nws yog kwv yees li 15% {4 {4}}% hauv cov ntsaws ruaj ruaj thiab txog 9%}}}% hauv cov ntsaws ruaj ruaj.
O-Ring Ncab thiab zaws: Thaum txhim kho O-Ring hauv ib qho zawj, nws yuav tsum tau ncab lossis compressed. Yog tias qhov tseem ceeb ntawm kev ncab thiab compression yog loj heev, nws yuav ncab los ntawm 1% raws li kev txo tus ntoo khaub hlab ntawm ntu ntawm {6}}. 5%. Rau qhov sealing, nws yog qhov zoo tshaj plaws kom cov O-Ring hauv lub xeev ncab, nrog cov nyiaj tau tso cai tshaj plaws ntawm 6%; Rau cov xaim ntsaws ruaj ruaj, nws yog qhov zoo tshaj plaws rau compress cov o-ntiv nplhaib sib haum nws txoj kev ncig, nrog qhov tseem ceeb tshaj plaws uas tau tso cai ntawm 3%.
