Cov haujlwm ntawm cov txhuam hniav yog dab tsi?

Carbon txhuam (Carbon txhuam) tseem hu ua hluav taws xob txhuam, ua ib hom zawv zawg sib cuag, nws yog dav siv hauv ntau yam khoom siv hluav taws xob. Cov pa roj carbon txhuam zoo li me ntsis zoo li cov roj hmab sawb ntawm cov xaum, nrog cov xaim xaim tawm ntawm sab saum toj, thiab qhov loj me yog txawv. Cov txhuam hniav yog ib feem ntawm lub tshuab txhuam hniav uas yog nyob rau saum npoo ntawm lub commutator. Thaum lub cev muaj zog tig, lub zog hluav taws xob xa mus rau lub rotor coil los ntawm lub commutator.

Carbon brush is a device for transmitting energy or signals between the fixed part and the rotating part of a motor or generator or other rotating machinery. The main materials are graphite, fat-impregnated graphite, and metal (copper, silver) graphite. It is generally made of pure carbon plus coagulant, and its appearance is generally square. It is stuck on the metal bracket, and there is a spring inside to press it tightly on the rotating shaft. When the motor rotates, the electric energy is transmitted to the coil through the commutator. Since its main component is carbon, it is called a carbon brush, which is easy to wear. It should be regularly maintained and replaced, and carbon deposits should be cleaned.

Kev ua haujlwm ntawm cov txhuam hniav yog tsuas yog siv hluav taws xob thaum rub tawm ntawm cov hlau; nws tsis yog tib yam li hlau-rau-hlau txhuam; thaum hlau-rau-hlau txhuam yog conductive; kev sib txhuam quab yuam yuav nce; nyob rau tib lub sij hawm, qhov chaw uas lub handover yuav sintered ua ke; thiab carbon txhuam yuav tsis; vim tias carbon thiab hlau yog ob yam sib txawv; feem ntau ntawm nws cov kev siv yog siv nyob rau hauv motors; muaj ntau yam duab; muaj square thiab round, thiab lwm yam.

Lub luag haujlwm tshwj xeeb:
1. Txhawm rau muab lub zog rau lub rotor, qhov hluav taws xob sab nraud (excitation tam sim no) ntxiv rau lub rotor rotor (input tam sim no) los ntawm cov pa roj carbon txhuam.
2. Qhia tus nqi zoo li qub ntawm tus ncej loj rau hauv av (av txhuam cov pa roj carbon monoxide) los ntawm cov txhuam hniav (tso tawm tam sim no).
3. Coj cov ncej loj (hauv av) mus rau cov cuab yeej tiv thaiv rau rotor av tiv thaiv thiab ntsuas qhov zoo thiab qhov tsis zoo ntawm lub rotor rau hauv av.
4. Hloov cov kev taw qhia ntawm tam sim no (nyob rau hauv lub commutator motor, txhuam kuj plays lub luag hauj lwm ntawm commutation).

Carbon txhuam yog tsim rau txhua yam ntawm lub cev muaj zog, lub tshuab hluav taws xob, thiab lub tshuab qag. Nws muaj kev ua haujlwm zoo rov qab thiab ua haujlwm ntev. Cov txhuam hniav yog siv rau ntawm lub commutator lossis lub nplhaib plam ntawm lub cev muaj zog. Raws li zawv zawg sib cuag lub cev uas coj thiab xa tawm tam sim no, nws muaj hluav taws xob zoo conductivity, thermal conductivity thiab lubricating kev ua tau zoo, thiab muaj qee yam kev siv zog thiab kev xav ntawm kev sib hloov. Yuav luag txhua lub cev muaj zog siv cov txhuam hniav, uas yog ib feem tseem ceeb ntawm lub cev muaj zog. Dav siv nyob rau hauv ntau yam AC thiab DC generators, synchronous motors, roj teeb DC motors, crane motor collector rings, ntau hom vuam tshuab thiab hais txog. Nrog rau kev loj hlob ntawm kev tshawb fawb thiab thev naus laus zis, hom motors thiab kev ua haujlwm ntawm kev siv tau dhau los ua ntau thiab ntau haiv neeg.
