Qhov Txawv Tseem Ceeb ntawm Silicon Carbide thiab Tungsten Carbide Mechanical Seals
Kev Sib Piv ntawm Cov Khoom Siv Lub Cev thiab Tshuaj
Silicon Carbide, cov tshuaj no tuav cov qauv crystalline uas muaj silicon thiab carbon atoms. Nws tuav cov thermal conductivity tsis sib xws ntawm cov ntaub ntawv foob ntsej muag, qhov nyuaj siab ntsuas ntawm 9.5 ntawm Mohs scale - thib ob tsuas yog pob zeb diamond - ntxiv rau cov khoom tiv thaiv corrosion zoo heev. SiC kuj yog cov khoom siv ceramic tsis-oxide uas ua rau muaj kev tawv siab vim nws cov kev sib txuas covalent txhim khu kev qha loj hlob mus rau hauv cov khoom siv.
Tungsten Carbide yog ib qho hlau sib xyaw ua ke feem ntau ntawm Tungsten thiab Carbon. Nws yog tsim los ntawm cov txheej txheem hu ua sintering uas ua rau muaj qhov ntsuas khoom nyuaj heev qhov twg ntawm 8.5-9 ntawm Mohs nplai - tawv txaus rau txhua daim ntawv thov pov rau nws tab sis tsis nyuaj npaum li SiC. Ntxiv nrog rau qhov ntom ntom, WC qhia txog qib siab ntawm kev tawv nyob ib puag ncig cua sov; txawm li cas los xij, nws tsis ruaj khov tshuaj piv rau Silicon Carbide.
Qhov Txawv ntawm Kev Ua Haujlwm Hauv Qab Ntau Yam Kev Ua Haujlwm
Thaum piv rau kev ua tau zoo ntawm silicon carbide (SiC) thiab tungsten carbide (WC) mechanical seals nyob rau hauv ntau qhov chaw ua haujlwm sib txawv, nws yog ib qho tseem ceeb los tham txog lawv cov lus teb rau cov yam xws li qhov kub thiab txias heev, kev hloov pauv ntawm lub siab, cov xov xwm corrosive, thiab lawv lub peev xwm los tswj cov xwm txheej abrasive.
Hais txog kev tiv taus cua sov, silicon carbide ua rau muaj kev ua tau zoo heev ntawm cov thermal conductivity thiab tuaj yeem ua haujlwm tau zoo ntawm qhov kub siab 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 siab ua haujlwm tseem ceeb heev.
Ntawm qhov tsis sib xws, thaum xav txog kev tiv taus siab, tungsten carbide muaj qhov zoo dua li silicon carbide. Nws cov qauv denser ua rau nws tiv taus cov xwm txheej siab heev zoo dua li SiC. Yog li ntawd, WC seals yog qhov tsim nyog dua rau cov ntawv thov hnyav nrog kev siab siab koom nrog.
Nyob ntawm seb cov khoom siv ua haujlwm twg uas cov foob no raug rau, kev tiv thaiv corrosive ua lwm yam tseem ceeb rau kev ntsuam xyuas. Silicon carbide ua tau zoo dua li tungsten carbide hauv kev tiv thaiv cov kua qaub thiab alkaline vim nws cov tshuaj lom neeg tsis muaj zog. Yog li ntawd, SiC foob yog qhov nyiam dua hauv kev lag luam uas cuam tshuam nrog cov kua dej lossis cov pa roj hnyav.
Qhov kev tiv thaiv kev hnav ntawm ob hom foob no hloov rov qab mus rau qhov zoo ntawm tungsten carbide vim nws qhov nyuaj, ua rau nws zoo dua los daws cov teeb meem abrasive dhau lub sijhawm siv ntev.
Kev Sib Piv Tus Nqi
Feem ntau, tus nqi pib ntawm cov foob tungsten carbide tuaj yeem siab dua li cov khoom sib npaug silicon carbide vim nws qhov kev tiv taus hnav thiab cov khoom tawv. Txawm li cas los xij, nws yog ib qho tseem ceeb uas yuav tsum xav txog tsis yog cov nqi ua ntej xwb, tab sis kuj yog cov nqi ua haujlwm mus sij hawm ntev.
Txawm hais tias cov foob tungsten carbide yuav xav tau kev nqis peev ntau dua thaum pib, lawv lub neej ntev thiab kev ua haujlwm zoo tuaj yeem them taus qhov kev siv nyiaj pib no dhau sijhawm. Ntawm qhov tod tes, cov foob silicon carbide feem ntau pheej yig dua thaum xub thawj uas ua rau lawv yog qhov kev xaiv zoo rau cov lag luam uas xav txog kev siv nyiaj txiag. Txawm li cas los xij, vim lawv qhov kev tiv thaiv kev hnav qis dua hauv qee qhov xwm txheej, lawv yuav xav tau kev hloov pauv lossis kev saib xyuas ntau zaus ua rau cov nqi mus sij hawm ntev dua.
Qhov sib txawv ntawm kev ruaj khov thiab kev hnav tsis kam
Cov foob pob Silicon Carbide muaj qhov nyuaj tshwj xeeb nrog rau kev ua kom sov siab. Qhov kev sib xyaw ua ke no ua rau lawv tsis yooj yim hnav vim kev sib txhuam, txo lawv txoj kev pheej hmoo ntawm kev hloov pauv txawm tias nyob rau hauv cov xwm txheej ua haujlwm hnyav. Ntxiv mus, lawv qhov kev tiv thaiv tiv thaiv kev xeb tshuaj ntxiv ua rau lawv lub zog tag nrho.
Ntawm qhov tod tes, Tungsten Carbide mechanical seals muab lub zog thiab kev nruj tsis sib xws, uas pab lawv tiv taus kev nyuaj siab rau lub sijhawm ntev. Lawv qhov kev ruaj khov ua kom muaj kev ua tau zoo txawm tias thaum raug kev mob hnyav, ua rau lawv txoj kev tiv thaiv kev hnav tsis zoo.
Ob qho tib si cov ntaub ntawv no yeej tiv taus kev nthuav dav thermal; txawm li cas los xij, Silicon Carbide ua rau muaj kev tiv thaiv thermal zoo dua me ntsis piv rau Tungsten Carbide. Qhov no txhais tau tias SiC cov foob tsis tshua muaj feem yuav tawg lossis deform thaum raug rau kev hloov pauv kub sai - ib qho tseem ceeb uas pab txhawb rau qhov ruaj khov.
Yuav Xaiv Li Cas Ntawm Silicon Carbide Thiab Tungsten Carbide Mechanical Seals
Qhov tseem ceeb, nws yog ib qho tseem ceeb uas yuav tsum xav txog qhov chaw uas cov foob yuav ua haujlwm. Qhov ntawd suav nrog cov yam xws li qhov xwm txheej ntawm cov kua dej, qhov kub thiab txias, qib siab, thiab qhov ua tau ntawm cov khoom corrosive. WC tau txais kev hwm heev rau nws qhov rigidity thiab tolerable tiv taus 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 nyuaj siab heev.
Ntawm qhov tod tes, SiC ua rau pom kev tiv taus zoo heev rau kev poob siab thermal thiab corrosion uas ua rau nws zoo tagnrho rau cov ntawv thov uas muaj kev hloov pauv loj heev ntawm qhov kub thiab txias lossis cov kua dej corrosive heev. Nws cov yam ntxwv sib txhuam qis kuj txhais tau tias siv hluav taws xob tsawg dua yog li ua rau SiC cov ntsaws ruaj ruaj haum rau kev ua haujlwm hluav taws xob.
Tsis tas li ntawd xwb, kev xav txog nyiaj txiag yuav tsum tsis txhob raug tsis quav ntsej thaum ua qhov kev xaiv no; thaum WC muaj qhov nyuaj thiab hnav tsis kam, nws feem ntau kim dua li SiC. Yog li ntawd, yog tias kev txwv nyiaj txiag yog qhov txwv, kev xaiv SiC yuav yog qhov kev daws teeb meem uas ua tau yog tias tsis muaj cov xwm txheej ua haujlwm hnyav / ua puas tsuaj.
Qhov kawg tseem ceeb yog koj txoj kev ntseeg siab rau hom lag luam lossis kev paub dhau los nrog cov foob pob silicon carbide lossis cov foob pob tungsten carbide. Qee lub lag luam txuas ntxiv siv nyob ntawm cov ntaub ntawv keeb kwm lossis kev ua tau zoo yav dhau los ntawm kev siv ib hom dua lwm hom uas zoo li tsim nyog los ntawm kev ntseeg siab.
