Cov khoom siv txhuam carbon

Niaj hnub no peb tab tom tham txog cov txhuam carbon rau cov cuab yeej hluav taws xob. Txhuam carbon (Carbon brush), tseem hu ua txhuam, ua ib qho kev sib txuas, yog siv dav hauv ntau yam khoom siv hluav taws xob. Cov ntaub ntawv siv rau cov khoom siv txhuam carbon yog graphite, impregnated graphite, hlau (muaj tooj liab, nyiaj) graphite. Koj puas muaj cov txhuam carbon txaus kom dhau lub thawv?

📍 Thaum twg kuv thiaj yuav tsum tau hloov cov txhuam carbon?
① Lub txim hluav taws loj, cov txhuam carbon hlawv qhov chaw sib cuag ntawm lub rotor, tshem nws tawm thiab so nws nrog ntawv xuab zeb. Qhov xwm txheej ntawm lub txim hluav taws kuj tseem yuav yog tias cov tooj liab ntawm lub rotor converter siv tag, lub txim hluav taws luv luv loj, thiab kev ua haujlwm conductive txo qis.
② yuav tsis tig, siv cov txhuam carbon tas.
(3) Tsis yog ob qho xwm txheej saum toj no, uas yog, lub caij nplooj ntoos hlav hom txhuam carbon, lub zog ntawm lub caij nplooj ntoos hlav ib zaug tsis txaus, ua rau cov txhuam carbon thiab lub rotor sib cuag tsis nruj luv luv hluav taws xob, yuav tsum rub tawm cov hlau txhuam carbon tooj liab, ntxiv 2 lub caij nplooj ntoos hlav.
(4) Daim ntawv tooj liab saum toj ntawm cov txhuam carbon, daim ntawv tooj liab tsis muaj daim npav txoj haujlwm siv, qhov kev tig ntawm daim ntawv tooj liab ua rau cov hlau tooj liab saum toj no nruj, cov txhuam carbon tsis tuaj yeem sib cuag ze nrog lub rotor, lub txim hluav taws xob me me, thiab qhov xav tau tshem tawm thiab co.

📍 Yuav ua li cas txhuam carbon ua haujlwm
Txhuam lub cev muaj zog Txhua lub cev muaj zog yog tsim los ntawm stator thiab rotor, hauv DC lub cev muaj zog, txhawm rau ua kom lub rotor tig mus rau saum, koj yuav tsum hloov qhov kev taw qhia ntawm qhov tam sim no tas li, txwv tsis pub lub rotor tsuas yog tig tau ib nrab lub voj voog, uas zoo li kev caij lub tsheb kauj vab, ib txhais taw tsuas yog tuaj yeem caij ib nrab lub voj voog, yog li DC lub cev muaj zog yuav tsum hloov qhov tam sim no hauv rotor, uas yog, qhov kev taw qhia ntawm tus neeg coj tam sim no hauv qhov xav tau rov qab. Kev sib pauv ntawm lub commutator yog tias thaum tus neeg coj hluav taws xob raug muab tso rau hauv lub teb hluav taws xob los txiav tawm lub teb hluav taws xob, tus neeg coj yuav raug thawb tawm ntawm lub teb hluav taws xob zoo li qub, uas yog vim tias kab teb hluav taws xob ntawm lub teb hluav taws xob raug nias thiab deformed los ntawm lub teb hluav taws xob nyob ib puag ncig tus neeg coj, thiab kab teb hluav taws xob sim rov qab mus rau qhov ncaj, uas yog sib npaug rau kev tsim cov zog nyiam thiab repulsive kom ua rau lub cev muaj zog tig. Lub commutator muaj ob ntu semicircle sib cais los ntawm cov khoom rwb thaiv tsev. Ob ntu tig raws li txuas nrog txhuam carbon, thiab txhuam carbon txuas ntxiv mus rau ntu ntawm lub commutator uas ntsib lub zog tsav, yog li lub cev muaj zog rov ua dua tig.

📍 Teeb meem uas ntsib thaum hloov cov txhuam carbon thiab cov kev daws teeb meem
Teeb meem: 1, cov txhuam carbon hnav hnyav heev
Qhov laj thawj:
A. Qhov cuam tshuam ntawm cov khoom siv txhuam carbon. Cov chaw tsim khoom sib txawv, cov qauv sib txawv ntawm cov qauv txhuam carbon sib txawv, qhov hnav kuj txawv. Yog li ntawd, thaum hloov cov txhuam carbon, xaiv tib hom txhuam carbon;
B. Qhov tiav ntawm qhov chaw ntawm lub nplhaib swb. Qhov siab dua qhov tiav ntawm qhov chaw ntawm lub nplhaib swb, qhov me dua qhov sib txhuam coefficient thiab qhov qis dua qhov hnav ntawm cov txhuam carbon.
C Cov nyhuv ntawm lub caij nplooj ntoos hlav siab. Lub caij nplooj ntoos hlav siab dhau yuav ua rau lub txhuam carbon hnav ntau ntxiv; Tib lub sijhawm, lub caij nplooj ntoos hlav siab me dhau, txawm hais tias qhov kev sib txhuam ntawm txhuam carbon thiab lub nplhaib plam me me, tab sis qhov kev sib cuag tsis zoo yooj yim tsim cov hluav taws xob, uas kuj tsis xav tau;
D. Cov nyhuv ntawm tam sim no. Feem ntau, rau cov txhuam graphite carbon, tam sim no ntws los ntawm cov txhuam carbon zoo yog loj dua li tam sim no ntws los ntawm cov txhuam carbon tsis zoo, yog li qhov hnav ntawm cov txhuam carbon zoo yog loj dua li qhov hnav ntawm cov txhuam carbon tsis zoo, thiab qhov hnav ntawm lub nplhaib zoo yog ntau dua li lub nplhaib tsis zoo.
Cov kev daws teeb meem:
