Khoom muag ntawm O-ring seals
Lub nplhaib O-ring yog hu ua O-ring, uas yog lub nplhaib roj hmab nrog lub voj voog hla ntu. O-ring yog siv dav tshaj plaws hauv hydraulic sealing thiab pneumatic sealing tshuab. O-ring seals muaj kev sib khi zoo thiab tuaj yeem siv tau rau ob qho tib si zoo li qub thiab cov ntsaws ruaj ruaj reciprocating; lawv tuaj yeem tsis tsuas yog siv ib leeg xwb, tab sis kuj yog cov khoom siv tseem ceeb ntawm ntau cov khoom sib txuas ua ke. Nws muaj ntau yam kev siv. Yog tias cov khoom raug xaiv kom raug, nws tuaj yeem ua tau raws li qhov xav tau ntawm ntau yam kev txav chaw. Kev ua haujlwm siab tuaj yeem ua haujlwm ntawm lub tshuab nqus tsev ntawm 1.333 × 105Pa mus rau qhov siab ntawm 400MPa; Qhov ntsuas kub tuaj yeem yog los ntawm -60 degree txog 200 degree .
O-ring specification marking method yog: puab txoj kab uas hla Фi × hlau txoj kab uas hla d, piv txwv li: O-ring 20 * 2.4, Ⅱ-2 GB1235-76, 20 txhais tau tias lub puab kab ntawm lub nplhaib loj yog 20 hli, 2.4 txhais tau hais tias seem txoj kab uas hla ntawm lub nplhaib roj hmab yog 2.4 hli, Ⅱ-2 sawv cev rau hom roj hmab siv, GB1235 sawv cev rau tus qauv tooj, 76 sawv cev rau lub xyoo tus qauv tau luam tawm Kev sib khi ntawm cov tshuaj lom neeg siv. Qhov ntsuas kub yog qhov dav (-60 degree - ntxiv rau 220 degree), thiab lub siab tuaj yeem ncav cuag 1500Kg / cm2 hauv kev siv tas li (siv ua ke nrog lub nplhaib txhawb nqa).
Qhov no yog lub ntsiab lus luv luv ntawm O-ring foob. Los ntawm no, peb tuaj yeem nkag siab yooj yim ntawm O-ring foob, tab sis peb tsis muaj cov lus piav qhia tshwj xeeb ntawm no hais txog kev sib khi ua haujlwm. Koj tuaj yeem tshawb xyuas lwm yam xov xwm tshwj xeeb, O Cov khoom zoo ntawm lub nplhaib foob
