Yuav ua li cas xaiv Sealing nplhaib rau hydraulic system?
1. NBr Nitrile Roj Hmab Sealing Xov Ntiv nplhaib haum rau siv hauv roj av roj hmab hydraulic, dej, dej, roj silicone thiab lwm yam xov xwm. Nws yog qhov feem ntau dav siv thiab qis tshaj plaws siv roj hmab foob. Tsis haum rau siv nyob rau hauv polar cov kuab tshuaj xws li ketones xws li ketones, ozone, nitrohydrrocarbons, mek thiab chloroform. Qhov ntsuas huab cua kub yog -40 ~ 120 ℃. Thib ob, HNBr Hydrgertated Nitrile Roj Hmab Sealing muaj cov yam ntxwv zoo, lub kua muag tiv taus, huab cua tsis kam yog qhov zoo. Zoo dua hnav tsis kam tshaj li nitrile roj hmab. Haum rau kev ntxuav cov tshuab, Automotive Cool Tshuab Thiab Cov Tshuab Hauv Tub Yees Siv Cov Ib puag ncig tshiab ib puag ncig tub yees R134A. Tsis pom zoo rau kev siv cov cawv, esters, lossis cov kev daws teeb meem uas muaj ntxhiab. Qhov ntsuas ntsuas kub yog -40 ~ 150 ℃. Thib peb, FLS Fluorine Silicone Roj Hmab Sealing nplhaib muaj cov roj hmab roj fluorine roj fluorine thiab roj silicone, cov roj ua kom siab thiab qis dua yog qhov zoo. Nws yog resistant rau kev tawm tsam ntawm oxygen muaj cov tebchaw, muaj ntxhiab hydrocarbon muaj cov kuab tshuaj yeeb yaj kiab thiab chlorine muaj cov kuab tshuaj. Nws yog feem ntau siv rau kev pab, aerospace thiab lub hom phiaj tub rog. Raug rau cov kua Ketones thiab cov kua nres tsis pom zoo. Kev siv ntsuas kub yog -50 ~ 200 ℃.
2, Ntxiv rau cov kev xav tau ntawm cov khoom ntim sealing, lub nplhaib sib khi yuav tsum tau them sai sai hauv qab no: (1) elastic thiab resilient; (2) Lub cev muaj zog tsim nyog, suav nrog kev nthuav dav, elongation thiab rhuav lub zog. (3) Cov kev ua tau zoo yog ruaj khov, nws tsis yooj yim rau o hauv nruab nrab, thiab cov thermal contraction nyhuv (joule effect) yog me me. (4) Yooj yim rau cov txheej txheem thiab cov duab, thiab tuaj yeem ua kom muaj qhov loj me. (5) tsis corrode ze rau saum npoo av, tsis yog tshuaj tsis huv ntawm nruab nrab, thiab cov roj av feem ntau yog cov roj hmab los saum toj no yog feem ntau ua los ntawm cov khoom siv roj hmab. Muaj ntau ntau yam roj hmab, thiab muaj tas li tshiab cov roj av tshiab, kev tsim qauv thiab xaiv, yuav tsum nkag siab cov yam ntxwv ntawm ntau txoj kev xaiv roj hmab, kev xaiv tsim nyog.
3. Qhov Zoo
(1) Lub nplhaib sib khi yuav tsum muaj kev sib khi zoo hauv kev ua haujlwm siab thiab muaj qee qhov ntsuas kub thiab tuaj yeem txhim kho kev sib khi ua haujlwm nrog kev nce siab.
(2) Kev sib txhuam ntawm cov khw muag khoom sib txhuam thiab cov chaw txav yuav tsum yog qhov me me, thiab cov coefficient ntawm kev sib txhuam yuav tsum ruaj khov.
(3) Lub nplhaib sib khi tau muaj zog corrosion distance, tsis yooj yim rau hnub nyoog, tau them lub neej ntev, thiab tuaj yeem them nyiaj tau zoo tom qab hnav rau qee yam.
(4) Cov qauv yooj yim, siv tau yooj yim thiab tswj, yog li ntawd lub nplhaib sib khi tau muaj lub neej ntev. Foob Nplhaib Puas yuav ua rau xau dej, ua rau cov khib nyiab ntawm cov tshuab ua haujlwm, thiab txawm tias ua haujlwm tsis muaj kev ua haujlwm. Sab hauv xau yuav ua rau tus volumetric efficiency ntawm cov kab ke hydraulic kom poob sai sai, thiab cov haujlwm xav tau tsis tau, lossis txawm tias txoj haujlwm tsis tuaj yeem nqa tawm. Lub me me plua plav uas tshaj tawm cov kab ke tuaj yeem ua rau lossis exacerbate hnav ntawm cov kev sib txhuam ntawm cov dej xau hydraulic, txuas ntxiv mus rau txi. Yog li ntawd, ntsaws ruaj ruaj thiab cov khoom ntim khoom yog qhov tseem ceeb ntawm cov khoom siv hydraulic. Kev ntseeg tau thiab kev pabcuam lub neej ntawm nws txoj haujlwm yog qhov ntsuas tseem ceeb los ntsuas qhov zoo ntawm cov kab ke hydraulic.
