Kodi maburashi a carbon ndi chiyani?

Burashi ya Mpweya (Burashi ya Mpweya) imatchedwanso burashi yamagetsi, ngati njira yolumikizirana, imagwiritsidwa ntchito kwambiri pazida zambiri zamagetsi. Burashi ya kaboni imawoneka ngati mzere wa rabala wa pensulo, wokhala ndi mawaya otuluka pamwamba, ndipo kukula kwake ndi kosiyana. Burashi ya kaboni ndi gawo la mota yopukutidwa yomwe ili pamwamba pa commutator. Pamene injini ikuzungulira, mphamvu yamagetsi imatumizidwa ku koyilo ya rotor kudzera pa commutator.

Carbon burashi ndi chipangizo chotumizira mphamvu kapena ma siginecha pakati pa gawo lokhazikika ndi gawo lozungulira la mota kapena jenereta kapena makina ena ozungulira. Zida zazikulu ndi graphite, graphite yopangidwa ndi mafuta, ndi chitsulo (mkuwa, siliva) graphite. Nthawi zambiri amapangidwa ndi carbon yoyera kuphatikiza coagulant, ndipo mawonekedwe ake nthawi zambiri amakhala masikweya. Yakakamira pa bulaketi yachitsulo, ndipo mkati mwake muli kasupe woti ikaninikize mwamphamvu patsinde lozungulira. Pamene injini ikuzungulira, mphamvu yamagetsi imatumizidwa ku koyilo kudzera mu commutator. Popeza chigawo chake chachikulu ndi carbon, amatchedwa carbon brush, yomwe imakhala yosavuta kuvala. Iyenera kusamalidwa nthawi zonse ndikusinthidwa, ndipo ma depositi a kaboni ayenera kutsukidwa.

Ntchito ya carbon burashi makamaka kuyendetsa magetsi pamene akusisita ndi zitsulo; sizili zofanana ndi kukangana kwachitsulo ndi chitsulo; pamene kukangana kwachitsulo ndi chitsulo kumakhala kochititsa chidwi; mphamvu ya mkangano ikhoza kuwonjezeka; pa nthawi yomweyo, malo opereka akhoza sintered pamodzi; ndi maburashi a Kaboni sadzatero; chifukwa mpweya ndi zitsulo ndi zinthu ziwiri zosiyana; ntchito zake zambiri zimagwiritsidwa ntchito mu injini; pali mawonekedwe osiyanasiyana; pali makona ndi kuzungulira, ndi zina zotero.

Ntchito yapadera:
1. Kuti apereke mphamvu ku rotor, kunja kwamakono (chisangalalo chamakono) akuwonjezeredwa ku rotor yozungulira (kulowetsa panopa) kupyolera mu burashi ya carbon.
2. Yambitsani mtengo wokhazikika pa shaft yayikulu mpaka pansi (burashi ya kaboni) kudzera muburashi ya kaboni (yotulutsa pano).
3. Atsogolereni shaft yaikulu (nthaka) ku chipangizo chotetezera chotetezera pansi pa rotor ndikuyesa mpweya wabwino ndi woipa wa rotor pansi.
4. Sinthani mayendedwe apano (mu motor commutator, burashi imagwiranso ntchito yosinthira).

Maburashi a kaboni ndi oyenera mitundu yonse ya ma mota, ma jenereta, ndi makina a axle. Ili ndi magwiridwe antchito abwino komanso moyo wautali wautumiki. Burashi ya kaboni imagwiritsidwa ntchito pa commutator kapena slip mphete ya mota. Monga gulu lotsetsereka lolumikizana lomwe limatsogolera ndikutumiza kunja, limakhala ndi madulidwe abwino amagetsi, matenthedwe amafuta ndi ntchito zopaka mafuta, ndipo ali ndi mphamvu zamakina komanso chibadwa chambiri chosinthira. Pafupifupi ma motors onse amagwiritsa ntchito maburashi a kaboni, omwe ndi gawo lofunikira la mota. Amagwiritsidwa ntchito kwambiri m'majenereta osiyanasiyana a AC ndi DC, ma synchronous motors, ma batire a DC motors, mphete zotolera ma crane motor, mitundu yosiyanasiyana yamakina owotcherera ndi zina zotero. Ndi chitukuko cha sayansi ndi ukadaulo, mitundu ya ma mota ndi momwe amagwirira ntchito akuchulukirachulukira.
