Thepa le Bohlokoa ba Librashe tsa Carbon

borashe ba carbonkapa borashe ba motlakase ba e sebelisoang haholo lisebelisoa tsa motlakase. Li sebelisetsoa ho fetisa matšoao kapa matla pakeng tsa karolo e tsitsitseng le karolo e potolohang ea lienjene tse ling kapa jenereithara. Sebopeho se khutlonnetsepa, 'me lithapo tsa tšepe li kenngoa ka har'a selemo. Li-brushes tsa carbon ke mofuta oa ho kopana le ho thella, kahoo ho bonolo ho apara le ho e hloka ho nkeloa sebaka khafetsa le li-deposit tsa carbon tse seng li felile e tlameha ho hloekisoa.

Karolo e ka sehloohong ea borashe ba carbon ke khabone. Ha e sebetsa, e hatelloa ke seliba ho sebetsa karolong e potolohang joalo ka borashe, kahoo e bitsoa borashe ba carbon. Boitsebiso bo ka sehloohong ke graphite.

Graphite ke ntho ea tlhaho, e ka sehloohong karolo ke carbon, 'mala o motšo, opaque, semi-metallic luster, tlaase boima, bo ka khethoa ka menoana, graphite le daemane ke carbon, empa thepa ea bona e fapane haholo, e leng ka lebaka la ho fapana tokisetso ea liathomo tsa carbon. Le hoja sebopeho sa graphite e le carbon, eona ke thepa e hanyetsanang le mocheso o phahameng e nang le ntlha ea ho qhibiliha ea 3652°C. Ho sebelisa thepa ena e phahameng ea ho hanyetsa mocheso, graphite e ka sebetsoa hore e be a k'hemik'hale e hanyetsanang le mocheso o phahameng.

The conductivity ea motlakase ea graphite ke e ntle haholo, e fetang litšepe tse ngata le makhetlo a makholo ho feta a non-metal, kahoo e entsoe ka likarolo tsa conductive tse kang li-electrode le borashe ba carbon; sebopeho sa ka hare sa graphite etsa qeto ea lubricity lona molemo, 'me re hangata e sebelise mamating a mafome Ho kenya lerole la pentšele kapa graphite ka har'a senotlolo ho tla etsa ho bonolo ho bula lemati. Sena e lokela ho ba phello ea lubricating ea graphite.

borashe ba carbonhangata li sebelisoa ho DC lisebelisoa tsa motlakase. Li-motors tse hloekisitsoeng li entsoe ka stator le rotor. Ho mochine oa DC, e le ho etsa hore rotor e potolohe, tataiso ea hona joale e hloka ho fetoloa kamehla, ho seng joalo rotor e ka potoloha halofo ea a selikalikoe. Li-brushes tsa carbon li bapala karolo ea bohlokoa haholo ho li-motors tsa DC. borashe ba carbon tsamaisa nako pakeng tsa dikarolo tse tsamayang tsa enjene. Conduction ena ke e thellang conduction e ka fetisang hona joale ho tloha pheletsong e tsitsitseng ho ea karolong e potolohang ea jenereithara kapa enjene. Foreimi ea carbon e entsoe ka li-brush tse ngata tsa carbon, kahoo mokhoa ona oa conduction o boetse o etsa hore borashe ba carbon bo be bonolo ho apara, le carbon brushes e boetse e fetola tataiso ea hona joale, ke hore, karolo ea phetoho.

Enjene ea brushed e sebelisa mochini ho feto-fetoha, palo e ka ntle ea makenete ha e sisinyehe mme khoele e ka hare ea tsamaea. Ha enjene e sebetsa, mopalami le khoele li potoloha hammoho, 'me li carbon brush le tšepe ea makenete ha li sisinyehe, kahoo mopalami le carbon brush hlahisa khohlano ho phethela ho fetoha ha hona joale tataiso.

Ha motlakase o ntse o potoloha, li-coil tse fapaneng kapa mekhahlelo e 'meli e fapaneng ea coil e tšoanang e matlafatsoa, ​​e le hore lipalo tse peli tsa matla a khoheli a hlahisoang ke khoele a na le angle e nang le lipalo tse peli tse haufi ho stator ea makenete e sa feleng, 'me matla a hlahisoa ka ho ho koekoetla thupa e le 'ngoe le ho hoheloa ha palo e fapaneng ho khanna koloi ho potoloha.

borashe ba carbonli boetse li sebelisoa ho AC thepa. Sebopeho le thepa ea AC motor carbon brushes le DC motor borashe ba carbon ba tšoana. Ho li-motors tsa AC, borashe ba khabone bo sebelisoa ha tse ling li-rotor tse tsoelipanang li hloka lebelo le fapaneng, joalo ka li-drill tsa rona tse sebelisoang hangata le metjhini e benyang, mme ba hloka ho tjhentjha borashe ba k'habone kgafetsa.
