Ndeapi mabasa ecarbon brushes?

Carbon brush (Carbon brush) inonziwo electric brush, serudzi rwekutsvedza, inoshandiswa zvakanyanya mumidziyo yakawanda yemagetsi. Iyo kabhoni brashi inotaridzika senge rubber strip yepenzura, ine waya dzinobuda kubva kumusoro, uye saizi yakasiyana. Iyo kabhoni bhurashi chikamu cheiyo brashi mota iri pamusoro peiyo commutator. Apo motokari inotenderera, simba remagetsi rinoendeswa kune rotor coil kuburikidza ne commutator.

Carbon brush chishandiso chekufambisa simba kana masaini pakati pechikamu chakamisikidzwa uye chikamu chinotenderera chemota kana jenareta kana mumwe muchina unotenderera. Zvinhu zvikuru graphite, mafuta-impregnated graphite, uye simbi (mhangura, sirivheri) graphite. Inowanzo gadzirwa nekabhoni yakachena pamwe necoagulant, uye chitarisiko chayo kazhinji chikwere. Yakanamira pachibhuraketi chesimbi, uye pane chitubu mukati chekuitsikirira zvakasimba pamugero unotenderera. Kana mota ichitenderera, simba remagetsi rinoendeswa kune coil kuburikidza nemukombuta. Sezvo chikamu chayo chikuru chiri kabhoni, inonzi carbon brush, iyo iri nyore kupfeka. Inofanira kugara ichichengetwa uye kuchinjwa, uye carbon deposits inofanira kucheneswa.

Basa re carbon brush rinonyanya kuitisa magetsi paunenge uchikwesha simbi; hazvina kufanana nesimbi-ku-metal friction; apo metal-to-metal friction is conductive; simba rekukwevera rinogona kuwedzera; panguva imwe cheteyo, iyo nzvimbo iyo chipo chinogona kuitirwa pamwechete; uye mabhurashi eKabhoni haadi; nokuti kabhoni nesimbi zvinhu zviviri zvakasiyana; mazhinji ekushandiswa kwayo anoshandiswa mumamotors; kune maumbirwo akasiyana-siyana; kune mativi mana uye denderedzwa, zvichingodaro.

Basa chairo:
1. Kuti upe simba kune rotor, kunze kwekunze (excitation current) inowedzerwa kune rotor inotenderera (inopinza ikozvino) kuburikidza nekabhoni brush.
2. Kusuma static charge pane huru shaft kusvika pasi (grounded carbon brush) kuburikidza nekabhoni brush (output current).
3. Tungamira shaft yakakura (pasi) kune chidziviriro chekudzivirira kwe rotor pasi uye kuyera iyo yakanaka uye yakaipa voltage ye rotor kusvika pasi.
4. Shandura kutungamira kwezvino (mune commutator motor, brashi inotambawo basa rekuchinja).

Carbon brushes inokodzera marudzi ese emamotor, jenareta, uye ekisi muchina. Iyo ine yakanaka yekudzosera kuita uye hupenyu hurefu hwebasa. Iyo kabhoni brashi inoshandiswa pane commutator kana inotsvedza mhete yemota. Semuviri unotsvedza wekubata unotungamira uye unopinza kunze kwenyika, une yakanaka magetsi conductivity, thermal conductivity uye lubricating performance, uye ine imwe mechanical simba uye instinct ye commutation sparks. Anenge ese mota anoshandisa kabhoni mabhurashi, ayo ari chikamu chakakosha chemota. Inoshandiswa zvakanyanya muakasiyana AC uye DC majenareta, synchronous motors, bhatiri DC mota, crane mota yekuunganidzira mhete, mhando dzakasiyana dzemuchina wewelding uye zvichingodaro. Nekuvandudzwa kwesainzi uye tekinoroji, mhando dzemotor uye mamiriro ekushanda ekushandisa ari kuramba achiwedzera kusiyana.
