High-pressure nres twj tso kua mis FKM foob nplhaib
Cov roj hmab sealing system ntawm lub siab-siab nres twj tso kua mis ntawm lub zog tshiab tsheb yog ib qho tseem ceeb heev, feem ntau nyob rau hauv cov nram qab no yam.
Seal cov khoom xav tau
Txij li thaum nws yuav tsum tau tiv taus lub siab ntawm lub siab-siab nres cov kua, cov khoom sealing yuav tsum muaj kev ua haujlwm zoo heev thiab hnav tsis kam. Cov khoom siv feem ntau suav nrog nitrile roj hmab (NBR), fluororubber (FKM), thiab lwm yam.
Kev tsim qauv foob
Lub twj tso kua mis siab lub twj tso kua mis sealing feem ntau yog siv cov qauv ua ke, suav nrog ntau lub foob xws li O-rings, V-rings, thiab roj foob. Lawv qhov ntev geometric thiab kev teeb tsa yuav tsum raug tsim los ua kom muaj kev sib khi zoo.
Preload tsim
Lub preload ntawm lub foob yog ib qho ntawm cov tsis tseem ceeb, thiab nws yog ib qho tsim nyog yuav tsum tau ua tib zoo xav txog yam xws li lub siab, qhov kub thiab txias, thiab hnav kom zoo rau kev tsim qauv kom ntseeg tau tias kev sib khi ntev ntev.
Cov txheej txheem kho deg
Qhov chaw ua hauj lwm ntawm lub twj tso kua mis nres feem ntau siv cov txheej txheem tshwj xeeb ntawm cov txheej txheem xws li txheej txheej tawv los yog quenching los txhim kho hnav tsis kam thiab txo qhov kev pheej hmoo ntawm kev xau.

Kev tu thiab tu
Cov roj hmab ntsaws ruaj ruaj ntawm lub twj tso kua mis siab siab yuav tsum tau kuaj xyuas thiab hloov tsis tu ncua kom tsis txhob muaj teeb meem los ntawm kev laus thiab hnav. Kev kho yuav tsum tau ua nruj me ntsis raws li cov qauv tsim khoom.
Qhov loj qhov tseeb ntau yam ntawm O-ring ntawm lub siab-siab nres system yog raws li nram no
Cross-sectional dimension kam rau ua
Txoj kab uas hla ntawm txoj kab uas hla ntawm O-ring feem ntau yog tswj tsis pub dhau ±0.05mm. Kev kam rau siab loj heev yuav cuam tshuam rau kev ua haujlwm ua ntej thiab kev sib khi ntawm O-ring hauv qhov zawj.
Nto roughness
Qhov saum npoo roughness ntawm O-nplhaib kev sib cuag nto feem ntau yuav tsum yog Ra Tsawg dua lossis sib npaug rau 0.4μm. Nto ntxhib heev yuav ua rau kom hnav ntawm O-ring.
Hardness kam rau ua
Lub hardness ntawm FKM O-ring feem ntau yog tswj ntawm 70 ± 5Shore A. Cov hardness siab dhau yuav cuam tshuam rau kev sib khi, thiab tsis tshua muaj zog yuav txo qhov hnav tsis kam.
cov khoom siv thev naus laus zis
Inner diameter kam rau ua ntau yam
Tus qauv kam rau ua yog feem ntau nyob ib ncig ntawm ±{{0}}.10mm. Rau qee qhov loj me, nws tuaj yeem txo qis ntxiv rau hauv ± 0.05mm. Qhov no yog los xyuas kom meej tias O-ring tuaj yeem sib haum nrog lub ntsej muag mating thiab xyuas kom zoo sealing.
Roundness kam rau ua
Roundness kam rau ua
Lub roundness kam rau ua ntawm O-ring feem ntau tswj tsis pub dhau 0.02mm. Kev sib txawv ntau dhau ntawm qhov sib txawv yuav ua rau qhov sib txuas tsis sib xws thiab cuam tshuam rau kev sib khi.
Lwm qhov yuav tsum tau muaj: Cov duab, qhov sib xws, cov khoom sib xws thiab lwm yam kev ntsuas ntawm O-ring kuj yuav tsum tau tswj nruj me ntsis kom ntseeg tau tias kev ua haujlwm ruaj khov ntawm batch khoom.
