BS4518 Standard FKM O nplhaib

Cov ntaub ntawv muaj ntau yam txiaj ntsig rau cov neeg tsim qauv, cov kws tsav tsheb, cov neeg ua haujlwm hauv tsev thiab cov neeg ua haujlwm ntawm cov neeg ua haujlwm, lawv: nplua ntau lub chaw zoo li qub thiab dynamic; ntawm elastomer-raws li cov khoom hom

O-Nplhaib, qhov txiav ntug yog qhov "O", uas yog qhov ntau tshaj plaws, classic, nyiaj txiag thiab pab kom sib haum nyob rau hauv ob qho tib si daim ntawv thov dynamic thiab zoo li qub.
Yuav kom nkag siab txog lub tswv yim ntawm O-Ring, nws yog qhov tseem ceeb koj yuav tsum paub:

. Cov qauv ntawm O-Ring-dimension yog yooj yim heev, OD = ID + 2 * CS
.Qhov nrov O-Nplhai qauv yog tsim los ntawm nws qhov chaw thiab lub tebchaws
. O-nplhaib kam rau nws muaj kev txwv, thaum qhov loj me ntawm kev kam rau ua siab ntev; nws txhais tau hais tias tsis ua hauj lwm yuav ua rau to.
.-Rings yog ua los ntawm elastomers uas muaj resilience los yog nco txaus rov qab mus rau nws tus qauv zoo tom qab ib qho kev loj los yog me yuam kev

Fluorocarbon roj hmab muaj kev xyuam xim rau kev kub siab, ozone, oxygen, ntxhia roj, hluavtaws hydraulic, fuels, aromatics thiab ntau cov organic solvents thiab tshuaj. Nws muaj zog dua tuaj yeem ua rau hauv octane thiab roj cov pa oxygenated.

Kev kub ntawm kev tsis haum yog feem ntau tsis zoo thiab rau cov kev siv li niaj hnub txwv, tab sis nyob rau qee qhov xwm txheej nws haum rau -40 ° F (-40 ° C). Roj permeability yog tsawg heev thiab zoo ib yam li cov rubyl roj hmab. Cov tshuaj fluorocarbon tshwj xeeb muaj ib qho kev ua haujlwm zoo tuaj yeem ua rau cov kua qaub, roj, dej thiab tag.
