Yeyiphi imisebenzi yeebrashi zekhabhoni?
2022-11-23
Ibrashi yeCarbon (ibrashi yeCarbon) ikwabizwa ngokuba yibrashi yombane, njengohlobo lonxibelelwano lokutyibilika, isetyenziswa kakhulu kwizixhobo zombane ezininzi. Ibrashi yekhabhoni ibonakala ifana nomgca werabha wepensile, kunye neengcingo eziphuma phezulu, kwaye ubukhulu buhluke. Ibrashi yekhabhoni yinxalenye yemoto ekhutshiweyo ephezu komphezulu we-commutator. Xa i-motor ijikeleza, amandla ombane adluliselwa kwi-coil ye-rotor ngokusebenzisa i-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.
Umsebenzi we-carbon brush ngokuyinhloko kukuqhuba umbane ngelixa uxubha isinyithi; ayifani nentsimbi ukuya kwintsimbi; xa i-metal-to-metal friction is conductive; amandla okukhuhlana anokwanda; kwangaxeshanye, indawo apho unikezelo lunokudityaniswa khona; kwaye iibrashi zeCarbon aziyi; kuba ikhabhoni kunye nesinyithi zizinto ezimbini ezahlukeneyo; uninzi losetyenziso lwayo lusetyenziswa kwiinjini; kukho iimilo ezahlukeneyo; kukho isikwere kunye nengqukuva, njalo njalo.
Indima ethile:
1. Ukubonelela amandla kwi-rotor, i-current current (i-excitation current) yongezwa kwi-rotor ejikelezayo (i-input current) nge-carbon brush.
2. Yazisa umrhumo we-static kwi-shaft enkulu emhlabeni (ibrashi ye-carbon ephantsi) nge-carbon brush (imveliso yangoku).
3. Khokela i-shaft enkulu (umhlaba) kwisixhobo esikhuselayo sokukhusela umhlaba we-rotor kwaye ulinganise i-voltage efanelekileyo kunye nebi ye-rotor ukuya emhlabeni.
4. Guqula ulwalathiso lwangoku (kwi-motor commutator, i-brush nayo idlala indima yokutshintsha).
Iibrashi zekhabhoni zilungele zonke iintlobo zeenjini, iijenereyitha, kunye noomatshini beasi. Inomsebenzi omhle wokubuyisela umva kunye nobomi benkonzo ende. Ibrashi yekhabhoni isetyenziswa kwi-commutator okanye i-slip ring ye-motor. Njengomzimba woqhagamshelwano otyibilikayo okhokelela kwaye ungenisa ngoku, unokuqhuba kakuhle kombane, ukuhanjiswa kwe-thermal kunye nokusebenza kwe-lubricating, kwaye unamandla athile omatshini kunye nethuku leentlantsi zokutshintsha. Phantse zonke iimotor zisebenzisa iibrashi zekhabhoni, eziyinxalenye ebalulekileyo yemoto. Isetyenziswa kakhulu kwiijeneretha ezahlukeneyo ze-AC kunye ne-DC, ii-motor synchronous, ii-motor ze-DC zebhetri, amakhonkco omqokeleli we-crane motor, iintlobo ezahlukeneyo zoomatshini bokuwelda njalo njalo. Ngophuhliso lwesayensi kunye nethekhnoloji, iintlobo zeenjini kunye neemeko zokusebenza zokusetyenziswa ziya zihluka ngakumbi.
