Qhov txawv ntawm Silicon Carbide thiab Tungsten Carbide Mechanical Seals
Kev sib piv ntawm lub cev thiab tshuaj lom neeg
Silicon Carbide, qhov sib xyaw no tuav cov qauv crystalline tsim ntawm silicon thiab carbon atoms.Nws tuav unrivaled thermal conductivity ntawm lub ntsej muag cov ntaub ntawv, siab hardness nyob ntawm 9.5 ntawm lub Mohs nplai - thib ob tsuas yog pob zeb diamond - ntxiv rau cov khoom zoo heev corrosion kuj.SiC kuj yog cov khoom siv uas tsis yog-oxide ceramic uas ua rau muaj zog toughness vim nws cov kev ntseeg siab covalent bonds loj hlob directionally thoob plaws hauv cov khoom.
Tungsten Carbide yog ib qho alloy uas tsim los ntawm tungsten thiab carbon ntsiab lus.Nws yog tsim los ntawm cov txheej txheem hu ua sintering uas ua rau muaj qhov hnyav heev ntawm qhov ntsuas ntawm 8.5-9 ntawm Mohs nplai - tawv txaus rau txhua daim ntawv thov pov rau nws tab sis tsis nyuaj li SiC.Ntxiv nrog rau qhov ntom ntom, WC nthuav tawm qhov zoo kawg nkaus ntawm kev nruj ntawm cov cua sov;Txawm li cas los xij, nws tsis tshua muaj tshuaj lom neeg ruaj khov piv rau Silicon Carbide.
Qhov sib txawv ntawm kev ua tau zoo nyob rau hauv ntau yam kev ua haujlwm
Thaum muab piv cov kev ua tau zoo ntawm silicon carbide (SiC) thiab tungsten carbide (WC) txhua yam ntsaws ruaj ruaj nyob rau hauv ib puag ncig kev khiav hauj lwm sib txawv, nws yog ib qho tseem ceeb los tham txog lawv cov lus teb rau tej yam xws li kub kub, siab variations, corrosive media, thiab lawv lub peev xwm los lis abrasive tej yam kev mob.
Nyob rau hauv cov nqe lus ntawm tshav kub tsis kam, silicon carbide exhibits zoo heev thermal conductivity thiab muaj peev xwm ua hauj lwm zoo ntawm kub dua piv rau tungsten carbide.Cov yam ntxwv no ua rau SiC yog qhov kev xaiv zoo tshaj plaws rau cov ntawv thov uas qhov kub thiab txias yog qhov tseem ceeb heev.
Ntawm qhov tsis sib xws, thaum xav txog kev ua haujlwm siab, tungsten carbide tuav ib qho txiaj ntsig zoo dua silicon carbide.Nws cov qauv denser ua rau nws tiv taus huab cua siab zoo dua SiC.Yog li ntawd, WC cov ntsaws ruaj ruaj yog tsim nyog rau cov ntawv thov hnyav nrog rau kev kub ntxhov siab.
Nyob ntawm cov xov xwm ua haujlwm uas cov ntsaws ruaj ruaj raug nthuav tawm, corrosive kuj yog lwm qhov tseem ceeb rau kev ntsuas.Silicon carbide outperforms tungsten carbide nyob rau hauv resisting acidic thiab alkaline daws vim nws chemically inert xwm.Yog li ntawd, SiC cov ntsaws ruaj ruaj yog nyiam nyob rau hauv kev lag luam uas cuam tshuam nrog cov kua los yog roj.
Kev hnav tsis kam ntawm ob hom kev ntsaws ruaj ruaj hloov rov qab rau hauv kev pom zoo ntawm tungsten carbide vim nws qhov hardness innate, ua kom nws zoo dua los daws cov kev mob abrasive nyob rau lub sijhawm siv ntev.
Tus nqi sib piv
Feem ntau, tus nqi pib ntawm tungsten carbide ntsaws ruaj ruaj tuaj yeem siab dua qhov sib npaug ntawm silicon carbide vim nws cov khoom siv zoo tshaj plaws-ua haujlwm thiab hardness.Txawm li cas los xij, nws tseem ceeb heev uas yuav tsum xav txog tsis yog cov nqi them ua ntej, tab sis kuj yog cov nuj nqis ua haujlwm ntev.
Txawm hais tias tungsten carbide seals yuav xav tau kev nqis peev loj dua, lawv lub neej ntev thiab kev ua tau zoo tuaj yeem cuam tshuam qhov pib siv nyiaj ntau dhau sijhawm.Ntawm qhov tod tes, silicon carbide ntsaws ruaj ruaj feem ntau tsis tshua kim ua ntej uas ua rau lawv muaj kev xaiv zoo rau kev lag luam nyiaj txiag.Txawm li cas los xij, muab lawv cov kev sib piv qis qis dua nyob rau hauv qee yam kev mob, lawv yuav xav tau kev hloov pauv ntau zaus lossis kev saib xyuas ua rau cov nqi mus sij hawm ntev dua.
Qhov sib txawv ntawm Durability thiab Wear Resistance
Silicon Carbide mechanical seals muaj qhov tshwj xeeb hardness txuas nrog siab thermal conductivity.Qhov kev sib xyaw ua ke no ua rau lawv tsis tshua muaj kev cuam tshuam rau kev hnav vim kev sib txhuam, txo lawv txoj kev pheej hmoo ntawm deformation txawm nyob rau hauv kev ua haujlwm hnyav.Ntxiv mus, lawv cov resistivity tiv thaiv tshuaj corrosion ntxiv txhim kho lawv tag nrho durability.
Ntawm qhov tod tes, Tungsten Carbide mechanical seals muab lub zog tsis sib xws thiab nruj, uas pab tau lawv tiv taus lub cev hnyav rau lub sijhawm ntev.Lawv txoj kev ruaj khov ua kom muaj kev ua tau zoo ib yam txawm tias raug mob hnyav, ua kom lawv cov hnav tsis kam zoo.
Ob qho khoom siv yog inherently resistant rau thermal expansion;Txawm li cas los xij, Silicon Carbide nthuav tawm me ntsis zoo dua thermal shock kuj piv rau Tungsten Carbide.Qhov no txhais tau hais tias SiC cov ntsaws ruaj ruaj tsis tshua muaj kev tawg lossis deform thaum raug kub hnyiab kub hloov pauv - qhov tseem ceeb uas ua rau muaj txiaj ntsig zoo ntawm kev ua haujlwm ntev.
Yuav Ua Li Cas Xaiv Ntawm Silicon Carbide thiab Tungsten Carbide Mechanical Seals
Feem ntau, nws yog ib qho tseem ceeb uas yuav tau xav txog ib puag ncig uas cov ntsaws ruaj ruaj yuav ua haujlwm.Qhov ntawd yuav siv rau hauv tus account yam xws li qhov xwm txheej ntawm cov kua dej, qhov kub thiab txias, qib siab, thiab muaj peev xwm ntawm cov ntsiab lus corrosive.WC tau txais txiaj ntsig zoo rau nws txoj kev nruj thiab ua haujlwm ntev rau hnav.Yog li ntawd, nws tuaj yeem nyiam nyob rau hauv ib puag ncig uas xav tau kev ruaj khov tiv thaiv kev puas tsuaj lossis kev kub ntxhov.
Ntawm qhov tod tes, SiC nthuav tawm cov kev tiv thaiv zoo heev rau thermal shock thiab corrosion uas ua rau nws zoo tagnrho rau cov ntawv thov qhov kev hloov pauv ntawm qhov kub thiab txias yuav tsum muaj los yog cov kua dej corrosive heev.Nws cov kev sib txhuam qis qis kuj tseem cuam tshuam qhov kev siv hluav taws xob tsawg dua yog li ua SiC cov ntsaws ruaj ruaj haum rau kev ua haujlwm ntawm lub zog.
Tsis tas li ntawd, kev txiav txim siab nyiaj txiag yuav tsum tsis txhob tsis quav ntsej thaum xaiv qhov no;thaum WC boasts hwm hardness thiab hnav tsis kam, nws nyhav dua li SiC counterparts.Yog li, yog tias kev txwv nyiaj txiag yog qhov txwv tsis pub, kev xaiv rau SiC tej zaum yuav yog ib qho kev daws teeb meem uas tsis muaj kev ua haujlwm hnyav / ua rau puas tsuaj.
Qhov kawg tseem ceeb yog koj lub hom phiaj kev ntseeg siab lossis kev paub dhau los nrog silicon carbide mechanical seals lossis tungsten carbide mechanical seals.Qee lub lag luam txuas ntxiv siv nyob ntawm cov ntaub ntawv keeb kwm lossis kev ua haujlwm yav dhau los ntawm kev siv ib hom dhau lwm qhov uas zoo li tsim nyog los ntawm kev ntseeg tau.
Hauv kev xaus
Hauv kev xaus, Silicon Carbide thiab Tungsten Carbide mechanical seals yog ob txoj kev daws teeb meem rau kev siv tshuab siv tshuab.Thaum Silicon Carbide muaj qhov ua tau zoo thaum tshav kub kub thiab tshuaj lom neeg ruaj khov, Tungsten Carbide muaj npe nrov rau nws qhov ua tau zoo thiab muaj zog nyob rau hauv huab cua txias.Koj qhov kev xaiv ntawm ob cov ntaub ntawv no yuav tsum tau coj los ntawm koj cov kev xav tau tshwj xeeb thiab cov ntawv thov;tsis muaj universal tov.Peb pab neeg ua haujlwm raws caij nyoog ntawm XYZ Inc. ua tau zoo hauv kev muab cov kev hloov kho kom haum rau ntau yam kev xav tau kev lag luam nrog kev ua tau zoo.
