Dab tsi yog qhov sib zog ua ke ntawm O-Ring?

Lub compression piv ntawm ib tug o-ntiv nplhaib hais txog kev faib ua feem ntawm qhov cross-seem-infleal ntawm O-Ring txo qis tom qab raug rau compressive quab yuam. Nws yog ib qho kev ua tau tseem ceeb uas cuam tshuam rau cov nyhuv seading thiab kev pabcuam lub neej ntawm lub foob. Hauv qab no yog cov lus qhia ntxaws ntxaws txog tus nqi ntawm O-Rings:
1, xam txheem
Daim ntawv xam piv rau O-Ring compression piv yog: COMPRESS piv (W)=(do × 100%. Ntawm lawv, ua sawv cev rau cov kab hla hla ntawm O-Ring hauv qab ntawm O-Nplhaib Qhov siab, uas yog, tus ntoo khaub ncaws qhov siab ntawm O-Ring tom qab compression (hli).
2, xaiv ntau
Kev xaiv ntawm O-Ring compression piv qhov txawv nyob ntawm daim ntawv thov cov xwm txheej thiab cov xwm txheej ua haujlwm. Nov yog qee qhov kev xaiv ntau li:
Cov cuab yeej sib dhos zoo li qub: Feem ntau, qhov sib piv ntawm nruab nrab ntawm 15% mus rau 30% yog raug xaiv los xyuas kom meej cov nyhuv sib khi.
Reciprocating suab foob: lub compression sib npaug ntawm 10% rau 15% feem ntau tau raug xaiv los ua kom tau raws li cov kev xav tau.
Tig suab foob: thaum xaiv cov lej sib piv, cov txiaj ntsig cua sov joulele. Feem ntau hais lus, qhov sib piv Compression ntawm cov lus tsa suab qeeb qeeb kuj raug xaiv los ua 10% ~ 15%. Txawm li cas los xij, nws yuav tsum raug sau tseg tias O-Rings tsuas yog siv rau cov khoom siv qeeb qeeb qeeb qeeb qeeb qeeb qeeb qeeb qeeb qeeb qeeb qeeb qeeb qeeb qeeb qeeb qeeb qeeb qeeb qeeb.
3, muaj kev cuam tshuam txog yam
Kev ua haujlwm siab: Qhov ntau dua cov haujlwm siab, qhov siab dua qhov xav tau compression piv rau xyuas kom meej cov kev ua tau zoo.
Cov khoom nruab nrab: qhov kub thiab txias, corrosiveness, viscosity, thiab lwm yam ntawm cov nruab nrab tuaj yeem xaiv cov kev xaiv compression rau o-rings. Piv txwv li, kev kub tshaj tawm kub yuav ua rau cov khoom siv o-ntiv nplhaib, yog li nws yog qhov tsim nyog los kho cov compression piv txwv.
Cov Khoom Haum tawv: Cov khoom siv tawv ntawm cov O-rings kuj cuam tshuam rau lawv txoj kev ua tau zoo compression. O-rings nrog ntau dua hardness yuav muaj kev deformation tsawg thaum compressed, yog li yuav tsum tau ua kom tiav cov nyhuv uas xav tau.
4, Kev ceev faj
Thaum txhim kho o-rings, xyuas kom lawv raug muab tso rau hauv qhov zawj thiab tsis txhob muaj kev ncab ntau dhau los lossis zaws.
Nquag xyuas cov nyhuv seading ntawm O-Ring, thiab hloov nws sai yog tias muaj dej xau lossis kev puas tsuaj.
Kev tsim nyog xaiv cov khoom thiab Compresst piv ntawm O-nplhaib raws li cov lus thov sib txawv thiab cov kev ua haujlwm kom ntseeg tau tias nws lub neej kev ua haujlwm thiab lub neej pabcuam.
Lub compression piv ntawm O-RING yog qhov tseem ceeb ua ntsuas, thiab cov kev xaiv yuav tsum raug txiav txim siab raws li cov xwm txheej kev ua haujlwm tshwj xeeb. Los ntawm kev xaiv tsim nyog thiab kev teeb tsa, nws tuaj yeem ua kom muaj txiaj ntsig uas lub O-ntiv nplhaib ua lub luag haujlwm zoo hauv cov cuab yeej siv tshuab.
