Tuscarbon txhuam25 * 38 * 90, tseem hu ua cov nplaim hluav taws, yog zawv zawg kev sib cuag uas ua lub luag haujlwm tseem ceeb hauv ntau cov khoom siv hluav taws xob. Ua ib qho cuab yeej uas tuaj yeem hloov kho ntawm tus ncej kom hloov hluav taws xob lossis lub teeb liab plias lossis lub cim carbon) yog qhov tseem ceeb hauv cov motors, cov tshuab hluav taws xob, thiab lwm yam tig tshuab. Niaj hnub no, cia peb saib cov ncauj lus kom ntxaws ntawm cov qauv, khoom siv, thiab daim ntawv thov ntawm cov pa roj carbon.

Firstly, lub ntsiab tivthaiv ntawm cov carbon txhuam 25 * 38 * 90 yog carbon, feem ntau nrog qee tus nqi ntawm tus neeg tshuaj xyuas ntxiv rau kev ua luam. Nws muaj qhov thaiv zoo li zoo li lub ntsej muag thiab tau yooj yim tau clamped mus rau ib qho hlau nkhaus. Sab hauv cov pa roj carbon txhuam, muaj lub caij nplooj ntoo hlav uas tso cai txhuam hniav kom nruj tawm tsam tus ncej, kom muaj zog ruaj khov lossis hloov teeb liab thaum lub caij sib hloov. Txij li thaum lub ntsiab tivthaiv ntawm cov pa roj carbon txhuam yog carbon, nws muaj npe raws li xws li. Nws yog tsim nyog sau cia tias txhuam txhuam hniav yooj yim thiab yog li yuav tsum tau tu cov khoom siv thiab hloov chaw, nrog rau kev tu cov pa roj carbon dependits kom ntseeg tau tias ib txwm ua haujlwm.

Cov pa roj carbon txhuam zoo li tus lwv rau mem hluav, nrog cov xov hlau proruding los ntawm sab saum toj mus rau kis lub zog rau lub kauj. Qhov loj me ntawm cov pa roj txhuam txawv nyob ntawm cov cuab yeej xav tau.

Hais txog cov ntaub ntawv, carbon txhuam 25 * 38 * 90 feem ntau poob rau hauv peb pawg: lubricated graphite, thiab nws yog xim hlau (tooj liab, nyiaj ntsuab muaj) graphite. Roj ntsa nra zom cov txhuam hniav muaj qhov zoo thiab hnav tsis kam thiab haum rau cov neeg thauj khoom siab lossis cov tshuab hluav taws xob. Lubricated graphite txhuam hniav yog raws roj av graphite tab sis nrog ntxiv ntxiv lubricating roj, uas tau txhim kho nws cov teeb meem thiab txo cov hnav. Nws yog xim hlau graphite txhuam ntxiv tooj liab, nyiaj, thiab lwm yam kev coj ua, ua rau lawv tsim nyog rau kev siv nrog cov kev xav tau siab.

Hauv kev siv cov kev siv, xaiv thiab teeb tsa ntawmcarbon txhuam25 * 38 * 90 yog ib qho tseem ceeb heev. Kev xaiv tsis raug cai lossis cov txheej txheem tsis raug cai tuaj yeem ua rau hnav kom ua ntej hnav cov pa roj carbon txhuam lossis txawm tias cov khoom tsis ua haujlwm. Yog li ntawd, thaum xaiv cov pa roj carbon txhuam, nws yog qhov tseem ceeb uas yuav xav txog cov khoom siv, thauj khoom loj, thiab xaiv cov khoom siv hluav taws xob uas yog cov tshuaj ntsuab. Nyob rau tib lub sijhawm, thaum lub sijhawm txheej txheem teeb tsa, xyuas kom meej tias cov pa txhuam kom nruj nrog tus ncej thiab tias lub caij nplooj ntoos hlav siab ua haujlwm ntawm tus txhuam hniav.

Hauv cov ntsiab lus, tus pa taws txhuam 25 * 38 * 90 lis haujlwm ua ib qho tseem ceeb zawv zawg hu rau cov khoom siv hluav taws xob. Nkag siab txog nws cov qauv, khoom siv, tuaj yeem pab peb xaiv, nruab tau zoo, thiab tuav cov txhuam hniav, kom ua tiav cov haujlwm ntawm cov khoom siv. Yav tom ntej, nrog kev txhim kho txuas ntxiv thiab tsim hluav taws xob, qhov kev thov rau cov pa roj carbon kuj tuaj yeem loj hlob, thiab lawv cov ntawv thov kev cia siab hauv cov hluav taws xob yuav dhau los ua qhov dav dav.
