Hav nyob ntawd! Raws li ib tug neeg muag khoom ntawm graphite thrust bearings, kuv feem ntau tau nug txog dab tsi cov khoom me me no ua los ntawm. Yog li, cia peb dhia dej mus rau hauv cov khoom muaj pes tsawg leeg ntawm graphite thrust bearing thiab rhuav nws hauv cov ntsiab lus yooj yim.
Lub hauv paus ntawm Graphite
Ua ntej tshaj, graphite yog ib daim ntawv ntawm carbon. Nws yog ib qho ntawm cov khoom uas yog ob qho tib si super thiab tseem muaj qee qhov tshwj xeeb tiag tiag. Tej zaum koj tau pom graphite hauv koj cov xaum - "cov txhuas" yog graphite tiag tiag. Tab sis cov graphite siv nyob rau hauv thrust bearings yog tag nrho cov sib txawv ballgame.
Graphite muaj txheej txheej txheej. Duab nws zoo li ib pawg ntawm cov ntawv sau. Cov khaubncaws sab nraud povtseg tuaj yeem swb dhau ib leeg yooj yim, uas muab graphite nws cov khoom lubricating. Qhov no yog qhov laj thawj tseem ceeb vim li cas nws thiaj li zoo heev rau kev siv hauv bearings. Thaum cov khaubncaws sab nraud povtseg, lawv txo cov kev sib txhuam ntawm cov khoom txav, uas yog qhov tseem ceeb rau kev ua haujlwm ntawm cov tshuab.
Lub ntsiab Cheebtsam: Graphite nws tus kheej
Feem ntau ntawm graphite thrust bearing yog, ntawm chav kawm, graphite. Tab sis tsis yog ib qho graphite xwb. Peb siv siab - zoo, hluavtaws graphite. Synthetic graphite yog tsim los ntawm cua sov carbon - cov ntaub ntawv nplua nuj nyob rau hauv qhov kub thiab txias. Cov txheej txheem no tsim ib daim ntawv ntshiab thiab zoo ib yam ntawm graphite piv rau ntuj graphite.
Lub purity ntawm graphite yog qhov tseem ceeb. Cov impurities tuaj yeem cuam tshuam cov kabmob kev ua haujlwm. Piv txwv li, yog tias muaj cov khoom hlau hauv cov graphite, lawv tuaj yeem ua rau puas thiab hnav ntawm cov kabmob. Yog li, peb nco ntsoov siv graphite nrog cov ntsiab lus siab carbon, feem ntau tshaj 99%.
Reinforcements thiab Additives
Thaum graphite yog lub hnub qub ntawm cov yeeb yam, peb feem ntau ntxiv qee qhov kev txhawb nqa thiab cov khoom ntxiv los txhim kho cov kabmob kev ua haujlwm.
Fiberglass Reinforcement
Fiberglass yog ib qho ntawm cov khoom siv ntau tshaj plaws. Nws tau ntxiv kom muaj zog thiab nruj ntawm graphite thrust bearing. Xav txog nws zoo li ntxiv steel tuav rau pob zeb. Fiberglass strands yog sib xyaw rau hauv graphite matrix thaum lub sijhawm tsim khoom. Qhov no pab cov kabmob tiv taus cov loads siab dua thiab txo qhov kev pheej hmoo ntawm kev tawg lossis tawg hauv kev ntxhov siab.
Cov pa roj carbon fibers
Carbon fibers yog lwm qhov zoo ntxiv. Lawv muaj zog dua li fiberglass thiab muaj thermal conductivity zoo heev. Qhov no txhais tau tias lawv tuaj yeem pab dissipate cua sov zoo dua los ntawm cov kabmob. Thaum tshav kub kub yog ib tug yeeb ncuab loj ntawm bearings, raws li nws muaj peev xwm ua rau cov graphite nthuav thiab hloov nws cov khoom. Los ntawm kev siv cov pa roj carbon fibers, peb tuaj yeem khaws cov kabmob ua haujlwm ntawm qhov kub thiab txias, uas ua rau nws txoj sia ntev.
Lubricating Additives
Peb kuj ntxiv ib co lubricating additives rau graphite. Cov no tuaj yeem yog cov khoom xws li molybdenum disulfide lossis tungsten disulfide. Cov tshuaj no ua haujlwm ua ke nrog cov graphite lub ntuj lubricating zog los muab kev sib txhuam zoo dua. Lawv tsim ib zaj duab xis nyias ntawm cov kabmob, uas txo qis kev hnav thiab tsim kua muag.
Cov ntaub ntawv
Txhawm rau tuav tag nrho cov khoom no ua ke, peb siv binders. Binders zoo li cov kua nplaum uas khaws cov graphite, cov khoom siv ntxiv, thiab cov khoom ntxiv rau hauv qhov chaw. Muaj ntau hom binders peb siv tau, tab sis phenolic resins yog nrov heev.
Phenolic resins muaj zog thiab kub - resistant. Lawv tuaj yeem tiv taus qhov kub siab uas cov kabmob yuav ntsib thaum lub sijhawm ua haujlwm. Thaum lub binder kho tau, nws tsim ib qho nyuaj matrix uas encapsulates tag nrho lwm cov ntaub ntawv, tsim ib tug ruaj khov thiab ruaj bearing.
Sib piv nrog lwm cov khoom
Tam sim no, thaum peb tab tom tham txog cov khoom lag luam graphite, nws tsim nyog hais txog qee yam ntawm peb cov khoom siv. Peb kuj muab Graphite Saw Hniav. Cov saw hniav no yog tsim los ntawm siab - zoo graphite thiab yog tsim los txiav ntau yam ntaub ntawv. Lawv muaj kev tiv thaiv kub zoo heev thiab tuaj yeem tswj tau lawv qhov kev ua tau zoo rau lub sijhawm ntev.
Lwm cov khoom yog Pob Zeb Diamond Sintering Pwm. Cov pwm no yog siv los tsim cov cuab yeej pob zeb diamond. Cov khoom siv graphite hauv cov pwm no tuaj yeem tiv taus qhov kub siab thiab kub uas yuav tsum tau ua rau pob zeb diamond sintering, ua kom cov khoom zoo siab -.
Thiab cia peb tsis txhob hnov qab Graphite Thermal Sheet. Nws yog ib qho kev daws teeb meem zoo rau kev tswj cov cua sov hauv cov khoom siv hluav taws xob. Lub siab thermal conductivity ntawm graphite tso cai rau nws sai sai hloov tshav kub ntawm cov khoom rhiab heev.
Yog vim li cas peb Graphite Thrust Bearings yog qhov zoo
Peb cov graphite thrust bearings muaj ntau yam zoo. Ua ntej, lawv tus kheej - lubricating zog txhais tau hais tias lawv yuav tsum tau kho tsawg dua piv rau cov tsoos hlau bearings. Koj tsis tas yuav ntxiv lubricants, uas txuag lub sijhawm thiab nyiaj txiag.
Thib ob, lawv muaj peev xwm tiv taus corrosion. Graphite tsis xeb zoo li hlau, yog li nws tuaj yeem siv rau hauv qhov chaw hnyav, xws li hauv cov nroj tsuag tshuaj lossis kev siv dej hiav txwv.
Thaum kawg, lawv muaj thermal stability zoo heev. Lawv tuaj yeem ua haujlwm ntawm qhov kub thiab txias yam tsis poob lawv cov khoom siv kho tshuab. Qhov no ua rau lawv haum rau siv nyob rau hauv lub cav, turbines, thiab lwm yam siab - kev siv cua sov.
Tiv tauj peb rau koj cov kev xav tau
Yog tias koj nyob hauv kev ua lag luam rau siab - zoo graphite thrust bearings lossis ib qho ntawm peb cov khoom siv graphite, peb xav hnov los ntawm koj. Txawm hais tias koj yog ib lub chaw tsim khoom me me - lossis lub tuam txhab kev lag luam loj, peb tuaj yeem muab cov kev daws teeb meem zoo rau koj cov kev xav tau tshwj xeeb. Tsuas yog hu rau peb, thiab peb yuav pib sib tham txog yuav ua li cas peb tuaj yeem pab koj txhim kho koj lub tshuab ua haujlwm nrog peb cov khoom lag luam saum toj kawg nkaus - notch graphite.
