Maburashi a kaboni opangidwa ndi Morteng ndi zinthu zofunika kwambiri mu ma mota ozungulira (monga majenereta ndi ma mota amagetsi), omwe amagwiritsidwa ntchito makamaka kuchotsa mafunde a shaft, kuteteza chitetezo cha zida, komanso kuthandiza makina owunikira. Zochitika ndi ntchito zawo ndi izi:
I. Ntchito ndi Zotsatira Zapakati
- Pamene jenereta kapena mota ikugwira ntchito, kusalingana kwa mphamvu ya maginito (monga mipata yopanda mpweya kapena kusiyana kwa kuponderezedwa kwa coil) kungayambitse mphamvu ya shaft mu shaft yozungulira. Ngati mphamvu ya shaft idutsa mu filimu ya mafuta onyamula, imatha kupanga mphamvu ya shaft, zomwe zimapangitsa kuti shaft bearing electrolysis, mafuta awonongeke, komanso ngakhale kulephera kwa bearing.
- Maburashi a kaboni oyambira pansi a Morteng amafupikitsa shaft ya rotor kupita ku nyumba ya makina, kutembenuza mafunde a shaft kupita pansi ndikuletsa kuti asadutse m'maberiya. Mwachitsanzo, majenereta akuluakulu nthawi zambiri amaika maburashi a kaboni oyambira pansi kumapeto kwa turbine, pomwe maberiya oyambira pansi amakhala ndi ma insulating pads, kupanga mawonekedwe akale a 'excitation end insulation + turbine end grounding'.
II. Zochitika Zachizolowezi Zogwiritsira Ntchito
-Majenereta amagetsi otentha/ogwiritsa ntchito madzi: Maburashi a kaboni ogwiritsidwa ntchito pansi pa nthaka a Morteng amayikidwa kumapeto kwa turbine, pamodzi ndi ma bearing otetezedwa kumapeto kwa chikoka, kuti athetse mphamvu yamagetsi yotulutsa mpweya. Mwachitsanzo, mu majenereta amagetsi otentha, ma bearing ogwiritsidwa ntchito pansi amadalira filimu yopyapyala yamafuta kuti ateteze mpweya, ndipo kuyika maburashi a kaboni pansi kumatha kuletsa kufalikira kwa ma electrolysis a zipolopolo za bearing.
-Ma turbine a mphepo: Amagwiritsidwa ntchito popangira ma generator rotors kapena machitidwe oteteza ma surge, zipangizo nthawi zambiri zimasankhidwa kuchokera ku graphite yachitsulo (yochokera ku mkuwa/siliva), yomwe imapereka mphamvu yoyendetsa bwino, kukana kuwonongeka, komanso kukana kwa mphamvu yamagetsi.
-Ma mota amphamvu/osinthasintha: Awa ali ndi chiopsezo chachikulu cha shaft current. Mwachitsanzo, Tonghua Power Generation Company idayika maburashi a carbon pansi pa drive end ya ma fan motor oyamba, pogwiritsa ntchito ma springs okhazikika kuti asapitirire mphamvu, motero kuthetsa vuto lakuti ma bearing oyambirira omwe amatetezedwa sakanatha kutseka shaft current kwathunthu.
-Kuyendera njanji: Mu ma mota ogwirira ntchito a magalimoto amagetsi kapena magalimoto a dizilo, maburashi a kaboni okhazikika amachotsa kusonkhana kwa magetsi osasinthasintha panthawi yogwira ntchito, amateteza ma bearing, ndikusunga kukhazikika kwa dongosolo lamagetsi.
