Chikonzero chekudzima kweJenareta Carbon Brush

Sekutsvedza kunobata kuitisa ikozvino, iyo kabhoni brashi inoshandiswa kusuma iyo excitation ikozvino inodiwa nejenareta mu rotor coil kuburikidza neinotsvedza mhete.Kuti uve nechokwadi chekushanda kwakajairika kwemota, kusarudzwa kwakaringana kwemhando yebhurashi kwakakosha.Nekuda kwezvakasiyana zviwanikwa uye matekiniki anoshandiswa mukugadzira mabhurashi, hunyanzvi hwavo hwehunyanzvi hwakasiyanawo.Nokudaro, pakusarudzwa kwebhurashi, funga nezvekushanda kwebhurashi uye zvinodiwa nebhurashi yemotokari.

Apo iyo jenareta iri mukushanda kwakajairika, zvikonzero zvekupisa kwebhurashi zvinowanzove zvinotevera:

1. Iyo carbon brush weave inopiswa.

Carbon bhurashi mabraids ari kushanda anowanzo ratidza kupisa kwepamusoro, kana isina kubatwa nenguva, inotungamira kune mabraids apiswa.Asi mabhururu emamwe majenareta akafukidzwa nekudzivirira, zvichiita kuti zviome kuwana kana zvapiswa.Kana ikasawanikwa uye ikatsiviwa nenguva, inopisa nhamba huru yekabhoni mabhurashi nekuda kwekuremerwa, uye pakupedzisira ita kuti jenareta irasikirwe nemagnetism.

Chikonzero chekuongorora: Nekuda kwekusakwana kwemhando yekabhoni brashi, kusakwana kana kusaenzana kudzvanywa kwekugara kuchimanikidza chitubu, kushandiswa kwakasanganiswa kwemhando dzakasiyana dzekabhoni brashi, kusabatana kwakashata pakati pekabhoni bhurashi uye inotsvedza mhete, brashi braid uye kabhoni brashi, nezvimwewo, kabhoni brashi. kugovera hakusi yunifomu, chikamu chekabhoni brashi chakapiswa nekuda kwekuremerwa.

2. Iyo kabhoni brashi inoputika zvisizvo.

Kurohwa kwekabhoni bhurashi kunowedzera kupfekwa kwekabhoni brashi, zvichikonzera kuwanda kwekabhoni poda yakaunganidzwa mubrashi grip, zvichikonzera kabhoni brashi kuputika, kusabatana kwakashata pakati pekabhoni bhurashi neinotsvedza mhete, kuderera kwekuyerera, zvichikonzera. mukuremerwa kwemamwe mabhurashi ekabhoni.

Chikonzero chekuongorora: Chikonzero chikuru chekurova kwekabhoni brashi ndeye eccentric kana kuti rusted slip ring, inoda kugadzirwa kana kukwenenzverwa nenguva.

3. Spark kutadza pakati pekutsvedza mhete nekabhoni brashi.

Kana paine spark pakati peinotsvedza mhete nekabhoni brashi, kana ikasagadziriswa nenguva, inorasikirwa neyakajairwa kushanda mumamiriro ekusangana, kukonzera mhete yemoto, kupisa kabhoni brashi uye brashi grip, uye kunyange kukuvadza. iyo inotsvedza mhete, zvichikonzera kudzika zvishoma.

Ongororo yechikonzero: Pane zvikonzero zviviri zvekutsvedza pakati pekutsvedza mhete nekabhoni brashi.

1) Nekuti kabhoni brashi inosvetuka.

2) Nekuda kwehunhu husina kukodzera hwekabhoni brashi, yakaderera graphite yemukati, yakanyanyisa kusvibiswa kwemukati kwakaomarara, kusabatana kwakashata pakati pekabhoni brashi uye inotsvedza mhete, pfarivari dzinoonekwa.

4. Tembiricha yemhete yekutsvedza yakanyanya.

Slip ring inoshanda tembiricha yakakwira nekuda kwezvikonzero zvakati:

1) Kusabatana kwakashata pakati pekabhoni bhurashi uye inotsvedza mhete inokonzerwa nemhando isina kukwana yekabhoni brashi kana kusakwana kumanikidza kwekugara kumanikidza chitubu.

2) Spark inogadzirwa pakati pekutsvedza mhete uye mhete yekuunganidzira.

Kune majenareta, zvindori zvinotsvedza uye kabhoni mabhurashi zvinogara zvisina simba zvinongedzo.Kune rimwe divi, iko kutarisana kwakananga pakati peiyo yakamira chikamu (kabhoni brashi) uye inotsvedza chikamu, uye iyo yekufambisa ikozvino kune inotenderera inotenderera ndiyo chikamu chakakosha cheiyo excitation rectification chikamu, icho chinokanganiswa nezvinhu zvakasiyana.Naizvozvo, kushanda uye kuchengetedzwa kwekabhoni mabhurashi uye slip zvindori zvinova zvakakosha.Vagadziri vejenareta vanofanirwa kuita basa nekugadzirisa basa nemazvo kuburikidza nemapoinzi anotevera:

1. Nyatsodzora kunaka kwekabhoni brashi.

Usati watsiva carbon brush, nyatsoongorora.Tarisa kutaridzika kwekabhoni brashi kuti uone kuti iri muchimiro chakanaka.

2. Nyatsodzora iyo kabhoni brashi yekutsiva maitiro.

Kana iyo kabhoni bhurashi iri kushanda yakapfekwa kusvika 2/3 yehurefu hwekabhoni brashi, tsiva kabhoni brashi nenguva.Usati watsiva carbon bhurashi, nyatsokwenenzvera bhurasho rekabhoni kuti riite seri uye ona kuti kabhoni brashi inogona kufamba yakasununguka ichikwira nekudzika mukati mebhurashi rinobata.Nharaunda pakati pemucheto wezasi webrashi grip uye nzvimbo yekushanda ye slip ring inofanira kudzorwa pa 2-3 mm.Kana chinhambwe chiri chidiki kwazvo, chinodhumhana neinotsvedza mhete uye kukuvara nyore.Kana chinhambwe chakakurisa, kabhoni brashi inosvetuka moto nekupenya zviri nyore.Huwandu hwemabhurashi ekabhoni achatsiviwa panguva imwe neimwe haifanire kudarika 10% yehuwandu hwemabhurashi ekabhoni padanda rega rega, uye rekodhi yekutsiva kabhoni brashi inofanira kuchengetwa.Mushandi anotsiva kabhoni brashi achamira pabheji rekudzivirira uye haabate mapango kana nhanho yekutanga nechikamu chekugadzika panguva imwe chete, uye haashande panguva imwe chete.Mushure mekunge kabhoni bhurashi itsva yaiswa mubhurashi rinobata, rinofanirwa kudhonzwa kumusoro nekudzika kuti ritarise kana kabhoni brashi inogona kukwira nekudzika zviri nyore.Kana paine kuvharika, bhurasho kabhoni rinofanira kukwenenzverwa kuti riite zvinodiwa.
