Zofunika ndi Kufunika kwa Maburashi a Carbon

Maburashi a carbonkapena maburashi magetsi ndi amagwiritsidwa ntchito kwambiri pazida zamagetsi. Amagwiritsidwa ntchito potumiza zizindikiro kapena mphamvu pakati pa gawo lokhazikika ndi gawo lozungulira la ma motors kapena jenereta. Maonekedwe amakona anayi, ndi mawaya zitsulo anaika mu masika. Maburashi a kaboni ndi mtundu wolumikizirana wotsetsereka, kotero ndizosavuta kuvala komanso amafunika kusinthidwa pafupipafupi komanso ma depositi a kaboni omwe atha ziyenera kutsukidwa.

Chigawo chachikulu cha carbon burashi ndi kaboni. Akamagwira ntchito, amapanikizidwa ndi kasupe kuti agwire ntchito yozungulira ngati burashi, choncho amatchedwa carbon burashi. Chinthu chachikulu ndi graphite.

Graphite ndi chinthu chachilengedwe, chake chachikulu chigawo chake ndi kaboni, mtundu wake ndi wakuda, opaque, semi-metallic luster, otsika kuuma, akhoza kutola ndi zikhadabo, graphite ndi diamondi zonse carbon, koma katundu wawo ndi wosiyana kwambiri , zomwe ziri chifukwa chosiyana kupanga ma atomu a carbon. Ngakhale kuti graphite ndi carbon, izo ndi chinthu chopanda kutentha kwambiri chomwe chimasungunuka pa 3652 ° C. Kugwiritsa mkulu kutentha kukana katundu, graphite akhoza kukonzedwa kukhala a kutentha kugonjetsedwa ndi mankhwala crucible.

Mphamvu yamagetsi ya graphite ndi zabwino kwambiri, zopambana zitsulo zambiri komanso nthawi mazana ambiri zomwe sizinali zitsulo, kotero amapangidwa kukhala zigawo conductive monga maelekitirodi ndi mpweya maburashi; kapangidwe mkati mwa graphite chimatsimikizira lubricity ake abwino, ndipo ife nthawi zambiri gwiritsani ntchito pazitseko za dzimbiri Kuyika fumbi la pensulo kapena graphite mu loko kumapanga ndikosavuta kutsegula chitseko. Izi ziyenera kukhala zokometsera za graphite.

Maburashi a carbonNthawi zambiri amagwiritsidwa ntchito ku DC zida zamagetsi. Ma motors opukutidwa amapangidwa ndi stator ndi rotor. Mu injini ya DC, kuti ipangitse kuzungulira kozungulira, komwe kumayendera pano amayenera kusinthidwa nthawi zonse, apo ayi rotor imatha kuzungulira theka la a kuzungulira. Maburashi a kaboni amatenga gawo lofunikira kwambiri pama motors a DC. Maburashi a carbon yendetsa mphamvu pakati pa mbali zosuntha za injini. Conduction iyi ndi yotsetsereka ma conduction omwe amatha kusamutsa apano kuchokera kumapeto okhazikika kupita ku gawo lozungulira la jenereta kapena motere. Chojambula cha carbon chimapangidwa ndi maburashi angapo a carbon, kotero njira yoyendetserayi imapangitsanso maburashi a kaboni kukhala osavuta kuvala, ndi mpweya maburashi komanso kusintha malangizo a panopa, ndiye udindo wa kusintha.

Galimoto ya brushed imatengera makina kusinthasintha, mtengo wakunja wa maginito susuntha ndipo koyilo yamkati imayenda. Pamene injini ikugwira ntchito, commutator ndi koyilo zimazungulira pamodzi, ndi burashi mpweya ndi zitsulo maginito sasuntha, kotero commutator ndi kaboni burashi kutulutsa kukangana kuti amalize kusintha kwa pano malangizo.

Pamene injini imazungulira, ma koyilo osiyanasiyana kapena magawo awiri osiyana a koyilo yemweyo amapatsidwa mphamvu, kotero kuti mizati iwiri ya mphamvu ya maginito yopangidwa ndi koyiloyo imakhala ndi ngodya yokhala ndi mizati iwiri yotseka kwa okhazikika maginito stator, ndi mphamvu kwaiye kudzera kunyansidwa kwa mzati womwewo ndi kukopa kwa mzati wosiyana kuyendetsa injini kuzungulira.

Maburashi a carbonamagwiritsidwanso ntchito mu AC zida. Mawonekedwe ndi zinthu za AC motor carbon brushes ndi DC motor maburashi a carbon ndi ofanana. Mu ma motors a AC, maburashi a kaboni amagwiritsidwa ntchito pomwe ena zokhotakhota zimafunikira liwiro losinthika, monga zobowolera zamagetsi zomwe timagwiritsa ntchito ndi makina opukutira, ndipo amafunika kusintha maburashi a kaboni pafupipafupi.
