Carbon txhuam, tseem hu ua hluav taws xob txhuam, yog dav siv nyob rau hauv ntau yam khoom siv hluav taws xob raws li zawv zawg sib cuag. Cov ntaub ntawv tseem ceeb siv rau cov txhuam hniav hauv cov khoom yog graphite, greased graphite, thiab hlau (xws li tooj liab, nyiaj) graphite. Cov txhuam hniav yog ib qho cuab yeej uas xa lub zog los yog cov teeb liab ntawm qhov chaw ruaj khov thiab qhov sib hloov ntawm lub tshuab hluav taws xob lossis lub tshuab hluav taws xob lossis lwm lub tshuab tig. Nws feem ntau yog ua los ntawm cov pa roj carbon ntshiab thiab coagulant. Nws muaj lub caij nplooj ntoos hlav los nias rau ntawm lub rotating ncej. Thaum lub cev muaj zog tig, lub zog hluav taws xob raug xa mus rau lub kauj los ntawm lub commutator. Vim tias nws cov khoom tseem ceeb yog carbon, hu ua carbon txhuam, nws yooj yim rau hnav. Nws yuav tsum tau tu thiab hloov tsis tu ncua, thiab cov pa roj carbon deposits yuav tsum tau ntxuav.
Txhawm rau ua kom lub cev ua haujlwm ib txwm muaj, cov cim qhia tau zoo
carbon txhuamkev ua haujlwm yuav tsum yog:
1) Ib qho zoo, nruab nrab thiab ruaj khov oxide zaj duab xis tuaj yeem tsim sai sai rau ntawm qhov chaw ntawm lub commutator lossis lub nplhaib sib sau.
2) Cov txhuam hniav muaj lub neej ua haujlwm ntev thiab tsis hnav lub commutator lossis lub nplhaib sib sau
3) Cov pa roj carbon txhuam muaj kev sib hloov zoo thiab kev ua haujlwm tam sim no, kom lub txim raug tshem tawm hauv qhov kev tso cai, thiab lub zog poob yog me me.
4) Thaum twg
carbon txhuamyog khiav, nws tsis yog overheated, lub suab nrov me me, lub rooj sib txoos yog txhim khu kev qha, thiab nws tsis puas.
