Izinto zebhulashi lekhabhoni

Sikhuluma ngamabhulashi ekhabhoni amathuluzi kagesi namuhla. Ibhulashi lekhabhoni (ibhulashi lekhabhoni), elibizwa nangokuthi ibhulashi, njengendlela yokuxhumana eshelelayo, lisetshenziswa kabanzi emishinini eminingi kagesi. Ibhulashi lekhabhoni ezintweni zokusetshenziswa komkhiqizo ikakhulukazi i-graphite, i-graphite efakwe emanzini, i-graphite yensimbi (equkethe ithusi, isiliva). Unamabhulashi ekhabhoni anele okudlula ebhokisini?

📍 Kunini lapho ngidinga ukushintsha ibhulashi lekhabhoni?
① Inhlansi inkulu, ibhulashi lekhabhoni lishisa ubuso bokuthintana kwe-rotor, liyisuse bese liyisula nge-sandpaper. Isimo senhlansi singase sibe ukuthi ithusi eliku-rotor converter seliphelile, inhlansi ye-short-circuit inkulu, futhi ukusebenza komoya ohambisa umoya kuyancipha.
② ngeke iphenduke, ibhulashi lekhabhoni seliphelile.
(3) Akukho nanye kwezimo ezimbili ezingenhla, okungukuthi, ibhulashi lekhabhoni lohlobo lwentwasahlobo, ingcindezi yentwasahlobo eyodwa ayanele, okuholela ekutheni ibhulashi lekhabhoni kanye nokuxhumana kwe-rotor kungabi yi-spark ye-short circuit eqinile, kudingeka ukhiphe ucingo lwethusi lwebhulashi lekhabhoni, wengeze iziphethu ezimbili.
(4) Ishidi lethusi elingaphezu kwebhulashi lekhabhoni, ishidi lethusi elingenayo indawo yekhadi liyasetshenziswa, ukuzungeza kweshidi lethusi kubangela ukuthi ucingo lwethusi olungenhla luqine, ibhulashi lekhabhoni alikwazi ukuxhumana eduze ne-rotor, inhlansi incane, kanye nesidingo sokususa nokushukumisa.

📍 Indlela ibhulashi lekhabhoni elisebenza ngayo
Injini yebhulashi Zonke izinjini zakhiwe yi-stator kanye ne-rotor, ku-DC motor, ukuze i-rotor iphenduke phezulu, udinga ukushintsha njalo indlela yamanje, ngaphandle kwalokho i-rotor ingajika ingxenye yendilinga kuphela, okufana nokupheda i-pedal yebhayisikili, unyawo olulodwa lungapheda ingxenye yendilinga kuphela, ngakho-ke i-DC motor idinga ukushintsha indlela yamanje ku-rotor, okungukuthi, indlela yomqhubi wamanje lapho kudingeka ukuhlehla. Ukushintsha kwe-commutator ukuthi lapho umqhubi onamandla efakwa ensimini ye-electromagnetic ukuze anqume insimu yamagnetic, umqhubi uzosunduzelwa ngaphandle kwensimu yamagnetic engaguquki, okubangelwa ukuthi umugqa wensimu yamagnetic wensimu yamagnetic ucindezelwa futhi uphazamiseke yinsimu ye-electromagnetic ezungeze umqhubi, futhi umugqa wensimu yamagnetic uzama ukubuyela esimweni esiqondile, okulingana nokukhiqiza amandla akhangayo nacasulayo okwenza imoto iphenduke. I-commutator inezingxenye ezimbili eziyindilinga ezihlukaniswe ngezinto zokufaka umswakama. Izingxenye ezimbili zijikeleza ngokulandelana ukuze zixhumane nebhulashi lekhabhoni, kanti ibhulashi lekhabhoni lixhunywe ngokuphindaphindiwe engxenyeni ye-commutator ehlangabezana namandla okushayela, ukuze injini ephindaphindayo ijikeleze.

📍 Izinkinga ezitholakele ekushintsheni ibhulashi lekhabhoni nezixazululo
Inkinga: 1, ukuguguleka kwebhulashi lekhabhoni okukhulu
Isizathu:
A. Ithonya lezinto zebhulashi lekhabhoni. Abakhiqizi abahlukene, amamodeli ahlukene esakhiwo sebhulashi lekhabhoni ahlukile, izinga lokuguguleka nalo lihlukile. Ngakho-ke, uma ushintsha ibhulashi lekhabhoni, khetha uhlobo olufanayo lwebhulashi lekhabhoni;
B. Ukuphela kobuso bendandatho yokushelela. Uma ukuqeda kobuso bendandatho yokushelela kuphakeme, kulapho i-friction coefficient iba ncane futhi izinga lokuguguleka kwebhulashi lekhabhoni liphansi.
C Umphumela wokucindezela kwentwasahlobo. Ukucindezela kwentwasahlobo okweqile kuzokwenza ukuthi ukuguguleka kwebhulashi lekhabhoni kwande; Ngesikhathi esifanayo, ukucindezela kwentwasahlobo kuncane kakhulu, yize ukungqubuzana phakathi kwebhulashi lekhabhoni nendandatho yokushelela kuncane, kodwa ukuxhumana okubi kulula ukukhiqiza izinhlansi, okuyinto engafiseleki futhi;
D. Umphumela wamandla kagesi. Ngokuvamile, ngamabhulashi e-graphite carbon, amandla kagesi ageleza ngebhulashi le-carbon elihle likhulu kunolamandla kagesi ageleza ngebhulashi le-carbon elihle, ngakho-ke ukuguguleka kwebhulashi le-carbon elihle likhulu kunolamandla kagesi ageleza ngebhulashi le-carbon elihle, kanti ukuguguleka kwendandatho yokushelela enhle kungaphezu kwendandatho yokushelela embi.
