Carbon Brush Bakeng sa Motor

Carbon Brush bakeng sa Motor

Hangata li-brushes li bitsoa "carbon brushes" ka lisebelisoa tsa motlakase. Ke karolo ea enjene. Ntle le ho hokahanya elektrone le potoloho ea kantle ho enjene, e boetse e bapala karolo ea hona joale. Sehokelo se fokolang le sa bohlokoa sa enjene se thehoa ke borashe bo nang le motataisi. Ha ho na ho roala ha mochini feela le ho sisinyeha ha mochini pakeng tsa borashe le motataisi, empa hape ho na le tlhase e matla ka nako ea ts'ebeliso, e tla fokotsa haholo bophelo ba "wiper", empa hape e ama ts'ebetso e tloaelehileng ea mochini. Ka hona, khetho e nepahetseng ea lisebelisoa tsa borashe, boholo le khatello ea selemo, e tla bapala karolo ea bohlokoa haholo ho ntlafatseng ts'ebetso ea koloi le ho lelefatsa bophelo ba eona ba ts'ebeletso.

Khetho ea borashe e itšetlehile haholo ka mocheso o nyolohang oa borashe, 'me tataiso ea tataiso ea tataiso e khethoa. Ho phahama ha mocheso oa borashe ho amana le ho teteana ha bristle ka bongata ba ho kopana le tataiso, tahlehelo ea mochine le conductivity ea mocheso oa brush. Haeba lebelo la mohala oa selikalikoe le phahame haholo, ho bonolo ho futhumatsa borashe le motataisi, tlhase e eketseha, 'me ho roala ha borashe le ho hlakola ho mpefala.
Kenyelletso ea sebopeho, likarolo le ts'ebetso ea brashi ea khabone ea motor
Ho latela pono ea tšebeliso, haholo-holo ho na le matšoao a latelang a tšebeliso ea borashe bo botle: maemo a latelang:

1) Ha brush e ntse e sebetsa, e chesa, e lerata, ha e na tšenyo, ha e na 'mala, ha e chese;

2) E-ba le ts'ebetso e ntle ea tataiso, thibela tlhase sebakeng se lumelletsoeng, 'me tahlehelo ea matla e nyane;

3) Bophelo ba nako e telele ea tšebeletso 'me u se ke ua apara sesepa, u se ke ua etsa hore sesepa se hlakole, ho se lekane, ho chesa, ho hula, joalo-joalo;

4) Nakong ea ts'ebetso, filimi ea oxide e tšesaane, e itekanetseng le e tsitsitseng e ka thehoa ka potlako holim'a motataisi.


Sebopeho sa borashe
Tataiso ea ho kenya brashi ea borashe ea graphite ke: mofuta oa radial, ho sekamela ka morao le ho sekamela ka pele. Sebopeho sa radial se sebelisoang hangata, khatello ea selemo le eona e fapane. Haholo-holo ho na le liliba tsa nest line, spiral springs, le stretch springs. Mekhoa ena e meraro ea ho hatella nakong ea selemo ke ho sebetsa ka ho toba ka borashe ka khatello ea selemo; Essence

Classification le tshebetso ya borashe

1. Ho arola
Li-brushes hangata li aroloa ho latela sebopeho sa tsona sa embryo le mekhoa ea kalafo

a. borashe ba carbon graphite

Brush ea tlhaho ea graphite: borashe bo joalo bo na le voltage e phahameng ea ho kopana, ts'ebetso e ntle ea tokiso, ts'ebetso ea phallo e tlase e tlase ho feta borashe ba graphite ea motlakase, ts'ebetso e ntle ea lubrication, 'me e sebelisetsoa mela e phahameng e nang le lebelo le holimo.

Resin bonding brashi ea graphite: Mofuta ona oa borashe o tšoauoa ka khanyetso e kholo, motlakase o fokotsehileng oa ho ikopanya, ts'ebetso e ntle ea phetoho, antioxidant, le ho hanyetsa abrasion ho nepahetse, empa tšebeliso ea matla e sebelisoa haholo ho li-motors tsa AC.

b. Motlakase oa graphite brush

Brush e thehiloeng ho graphite (borashe bo bonolo): E khetholloa ka li-coefficients tse fokolang tsa likhohlano, ts'ebetso e ntle ea lubrication, ts'ebetso e ntle ea ho seta, botsitso ba mocheso, le ts'ebetso ea antioxidant; lienjineri tse kholo tsa li-synchronous tse nang le lebelo le phahameng la mela le meroalo e matla ea hang-hang Mechini e meholo e bilikang, le lienjene tsa DC tse nyane le tse mahareng;

Coke base brush (borashe bo thata bo bohareng): E khetholloa ka ho theoha ho hoholo ha motlakase oa likhokahano, e na le bokhoni bo botle ba ho etsa filimi, e na le bokhoni bo botle ba ho khutlisa tataiso, e na le phallo e itseng ea li-motor tse nang le mojaro o itseng oa tšusumetso, joalo-joalo Le likoloi tse akaretsang tsa DC tse nang le voltage e phahameng ho feta 220V;

borashe ba enke ea carbon (borashe bo thata): Mofuta ona oa borashe ke oa borashe bo sa khoneng ho emelana haholo le borashe ba electro-chemical graphite. E khetholloa ke khanyetso e kholo ea ho kopana le borashe le ts'ebetso e ntle ea tataiso. E sebelisoa bakeng sa li-motors tsa DC tse nang le bothata ba ho fetola tsela.

c. Sehlopha sa tšepe sa graphite brush
E na le tšepe le graphite. Litšobotsi tsa tšepe le graphite li lokisoa ke litšobotsi tsa conductivity e ntle ea tšepe le lubrication e ntle ea lubricating. E khetholloa ke motlakase o monyenyane oa ho kopana, coefficient ea ho hanyetsa le tahlehelo ea motlakase. Borashe bona bo sebelisoa haholo-holo bakeng sa li-motor tse kholo tse tlase-voltage le li-motor tse tsamaeang ka tlase tsa AC.

Tlhaho ea graphite borashe le electroextburra brush resistor coefficients le marotholi a khatello ea borashe a maholo, a hanana le abrasion, 'me lebelo la mohala le lumelloa ho sebelisoa (li ka fihla ho 50 ~ 70m/s). Metal graphite brush resistor coefficient le brush voltage e fokotseha hanyane, 'me ho hanyetsa ha abrasion ho fokola. Lebelo la mohala le lumelletsoeng ho sebelisoa le tlase. Hoo e ka bang 15 ~ 35m/s.

2. Tshebetso
Lintho tse ka sehloohong tsa theknoloji ea borashe li kenyelletsa li-resistors, boima, boima holim'a li-brushes tse peli, li-coefficients tsa likhohlano, liaparo tsa 50H, joalo-joalo. Coefficient ea ho hanyetsa ke bongata ba 'mele ho lekanya ts'ebetso ea conductive. Ho 230V, coefficient ea motlakase ea motlakase e ka khethoa e kholoanyane, 'me coefficient ea 120V brush resistor e tlameha ho ba nyane. Maqhubu a motlakase a 120V a nang le matla a tšoanang a maholo ho feta 230V. Ho futhumatsa, mocheso oa ho tšoara o ka 'na oa e-ba mpe haholo.

Ho theoha ha motlakase oa li-brashi ke phapang pakeng tsa phapano e ka bang teng lipakeng tsa motlakase o kenang ka har'a borashe ka switch ho ea borasheng. Ha borashe e kopana le e mong, 'me ho hanyetsa ha sebaka sa ho kopana ha sebaka sa ho kopana se etsahala tlas'a ketso ea matla a ka ntle, e bitsoa ho ferekana. Karo-karolelano ea likhohlano le khatello ea selemo ke coefficient ea khohlano ea borashe le tataiso. 50H ea ho apara boleng: Tlas'a maemo a boletsoeng a liteko, borashe e khethoa ke boima ba hona joale le khatello ea yuniti e behiloeng. Ha lebelo la mohala oa phetoho e le 15m / s, palo ea ho roala ha borashe e sila ka 50h.
