Khoom Txheej Txheem
Mor carbon o rings thiab carbon grabite sealing Cheebtsam yog cov khoom siv tshuab, tsim los tiv thaiv cov kua dej thiab roj xau. Nyob rau hauv tus qauv ntsuas kev ntsuas - 0.6 mpa kom siab thiab 25℃{}} tus nqi tsis tshua muaj li 0.01 ml / min. Crafted los ntawm high - Cov pa roj carbon ntau dua (cov roj ntsha ua tau zoo dua ntawm cov khoom lag luam uas tseem ceeb ntawm kev xav tau ntawm cov khoom siv
Cov Qauv Txheej Txheem ntawm Mor Carbon Foob Rings
Sab nraud saum npoo
Machined rau ra 0.8 μm roughness rau cov vaj tse nruj. Rau 100 hli sab nraud txoj hlua khi, siab tshaj plaws kev tshem tawm hauv tsev yog tsawg dua lossis sib npaug rau 0.03 mm, tiv thaiv kev ua haujlwm.
Sab hauv
Precision - av rau ra 0.4 μm, kom nruj nroos hlau hu. Rau 50 hli nyob rau hauv rings, chaw sib tiv toj nrog cov shaft loj dua los yog sib npaug ntawm 98%, tshem tawm cov kab mob xau txawm nyob rau hauv 1.5 mpa siab- siab} cov siab} kub.
Hla - seem
Txheem lub cev hla -} ntu muaj 5 txog 20 hli thickness thiab 10 txog 30 mm dav. Kev Cai Duab (Trapezoidal, U {{6} Zoo Li Cas Yog Nrog ± 0.03 mm Yam tsawg kawg nkaus kev tsim nyog, hloov mus rau Aerospace tshuab thiab cov khoom tshwj xeeb
Cov Nta Tseem Ceeb
Hnav Tsis kam
Cov carbon ci rauv nthuav tawm cov roj ua kom tiv taus tsawg dua lossis sib npaug rau 0.005 hli rau ntawm 1000,}, centrifugal twj tso kua (piv txwv li RPM). Qhov kev ua tau zoo no ua kom muaj kev ua tau zoo sib xws tshaj 8000 txog 12,000-teev kev pab cuam mus los, kev hloov cov roj hmab lossis tiv thaiv cov roj hmab lossis cov hlua roj hlau.
Thermal ruaj khov
Cov pa roj carbon tau txais qhov hluav taws xob ruaj khov txhawb kev ua haujlwm los ntawm -} 1000 depurch -the tus kheej kub ntawm kev lag luam lag luam. Txawm nyob ntawm 500 degree, kev hloov pauv hauv seem tseem tshuav tsawg dua lossis sib npaug rau 0.1%, zam kev foob tsis ua haujlwm. Qhov no ua rau lawv haum rau roj turbines, reciprocating compressors, thiab cov cav ntoo uas ua yeeb yaj kiab.
Tus kheej - roj tej yam ntxwv
Carbon lub ntuj tus kheej {{0} lubrication tau muab cov kev sib txhuam ua kom muaj kev sib txhuam coefficient ntawm 0..1 (qis dua li stainless hlau yog 0.15 txog 0.2). Cov pa roj carbon - Graphite composites txhim kho qhov no, txo cov ntsiab lus ntawm kev ua haujlwm ntawm 40% thiab tiv thaiv kev sib txhuam ntawm 40%} {}}} lubricated ntsaws ruaj ruaj.
Tshuaj Kuj
Cov pa roj carbon thiab carbon {- Graphite composites (cov sulfuric acid, sodium hydroxide, roj av). Nyob rau hauv 30% sulfuric acid nyob rau 25℃poob yog tsawg dua lossis sib npaug rau 0.02% rau 100- ua rau kev ua tsis taus. Qhov no tua cov tshuaj lom neeg ua yeeb yam, roj thiab roj, thiab tshuaj lag luam.
Tsawg sib txhuam coefficient
Kev sib txhuam coefficient ntawm 0.05 mus rau 0.1 ua haujlwm rau kev ua haujlwm ntawm kev tig. Rau ib qho 100 hli inch twj tso kua mis ncej ntawm 3000 rpm, qhov kev txiav hluav taws xob siv hluav taws xob los ntawm ~ 8% tiv thaiv cov ntsaws ruaj ruaj.
Seem ruaj khov
Cov pa roj carbon khaws nws cov duab thiab precision nyob rau hauv siab thiab sib txawv kub. Rau 50 rau 200 hli sab nraud ntawm lub taub hau, qhov ntev ntev yog ± 0.02 hli, ua kom lub ntsej muag zoo li cov kev mob khiav.
Cov Khoom Siv Khoom Siv
Cov pa roj carbon
Cov pa roj carbon muaj kub ua rau muaj 500℃thiab tshuaj lom neeg ua haujlwm (tsawg dua los yog sib npaug rau 0.02% poob qis hauv 30% sulfuric acid). Nws txawj ua kom zoo nyob rau hauv qhov siab tsis tu ncua- kub lossis corrosive} scen or lossis corrosive ecitors thiab siab - kub li qub.
Carbon - graphite composites
Muaj 15 txog 25% graphite, cov composations boost lubrication (sib txhuam coefficient 0.05 rau kev cuam tshuam (20% siab tshaj li cov pa roj carbon)). Lawv nyob nraum zoo rau kev sib hloov shareaf hauv centrifugal twj thiab cov ntsia hlau compressors.
Dav {- ni} kev siv
Twj Thiab Compressors
Siv Hauv Cov Khoom Siv Cov Ntsiav Sib Tw Nrog tsawg dua lossis sib npaug rau 0.01 ml / min so. Lawv qhov kev sib txhuam qis thiab kev hnav tsis kam thiab hnav tsis kam nplua 24/7 centrifugal twj thiab ntsia hlau compressors, txiav kev txij nkawm downtime los ntawm 30%.
Turbines thiab tshuab
Noj tes li 500℃thiab 2 mpa. Nyob rau hauv roj turbines, lawv tswj hwm tsawg dua lossis sib npaug rau 0.02 ml / min so thiab 10,000 txog 12,000-teev kev pab lub neej, ntsib cov qauv kev pab cuam thiab ib lub zog.
Li qub
Ua kom muaj kev txwv tsis pub xau - kev ua haujlwm pub dawb nrog 0.1 rau 2 mpa mpa mm 0.02 lub mm seem ruaj khov. Cov xov xwm tawm tsam (piv txwv li, roj thiab roj pipelines) thiab txiav ntau zaus los ntawm 25% tiv thaiv cov tshuab roj hmab.
Kev Lag Luam
Kev vam meej hauv kev thaj tsam ib puag ncig, Sealing Pipelines thiab reactors. Nyob rau hauv 30% sodium hydroxide, kev pab lub neej ncav cuag 8000 teev mus txog 8000 teev {{}} txhim khu kev qha rau cov nroj tsuag tshuaj.
Ib tug tub rog
Kev sib xyaw ua ke rau hauv cov tshuab tsim dav hlau (txog li 450 degree) thiab siab- kev ua haujlwm tshuab. Nrog 1.8 mus rau 2.0 g / cmter ntom (60% sib dua dua li cov hlau tsis muaj zog) thiab tsawg dua lossis sib npaug ntawm 5000 lub sijhawm ntsuas dav hlau, lawv tau raws li Aerospace cov kev xav tau.
