Chikonzero Ongororo yeCarbon Brush Kukundikana kweDiesel Jenareta

Kazhinji, mamwe madiki ejenareta edhiziri anoshandisawo alternator ine kabhoni mabhurashi.Alternator ine carbon brushes inofanira kuchengetedzwa uye kuchinjwa nguva dzose.Nhasi chinyorwa ichi chinonyanya kutaura nezvekuongororwa kwekabhoni brashi kukundikana kwe dhiziri jenareta .

Zvinhu zvinotungamira mukutadza kwekabhoni brashi:

Electromagnetic factor:

1. Kana iyo reactive simba kana excitation ikozvino inogadziriswa, spark ye carbon brush inoshanduka zviri pachena.Kana iyo exciter ichishandurwa, iyo kabhoni bhurashi haina kusangana neiyo commutator, uye iyo yekubata kuramba yakakura kwazvo;

2. Ukobvu husina kuenzana hwe oxide film ye commutator kana slip ring inokonzera kusaenzana kugoverwa kwecarbon brush current;

3. Kana kuti kamwe-kamwe kuchinja kwemutoro uye kamwe kamwe kupfupika kwedunhu kunotungamirira kune abnormal voltage distribution pakati pevafambi;

4. Unit kuwandisa uye kusaenzana;

5. Kusarudzwa kwemabhurashi kabhoni hakuna musoro, uye kuparadzaniswa kwekabhoni mabhurashi kwakasiyana;

6. Carbon brush quality matambudziko, nezvimwewo.

Mechanical factors:

1. Pakati pemufambisi haisi yakarurama uye rotor haina kuenzana;

2. Kudengenyeka kukuru kwechikwata;

3. Insulation pakati pevatyairi inobuda kunze kana kuti commutator inobuda;

4. Iyo yekubata kumeso kwekabhoni brashi haina kukwenenzverwa zvakanaka, kana pamusoro peiyo commutator ine hutsinye, zvichikonzera kusabatana kwakashata;

5. Nzvimbo ye commutator haina kuchena;

6. Mhepo yemhepo pasi pedanda rega rega rekuchinja rakasiyana;

7. Chitubu chinodzvinyirira pa carbon brush haina kuenzana kana hukuru husina kufanira;

8. Kabhoni bhurashi yakasununguka zvakanyanya mumubati webhurashi uye inosvetuka, kana yakanyanya kusimba, uye kabhoni brashi inonamira mumubati webhurashi.Iyo spark ichadzikiswa kana kumhanya kweiyo unit kwakadzikira kana vibration yakagadziridzwa.

Kemikari zvinhu: kana iyo unit ichishanda mugasi rinoparadza, kana kushaikwa kweokisijeni munzvimbo yekushanda yeyuniti, firimu remhangura oxide rakagadzirwa riri pamusoro peiyo commutator inosangana nekabhoni brashi inokuvadzwa, uye iyo kuchinjika kweyakagadzirwa mutsara kuramba hakuchisina.Munguva yemaitiro ekugadzirazve oxide firimu pane yekubata kumeso, iyo commutator spark inowedzera.Iyo commutator (kana inotsvedza mhete) yakasvibiswa neasidhi gasi kana girisi.Iyo kabhoni brashi uye commutator yakasvibiswa.

Kugadziriswa kwekabhoni brashi

A. Kuongorora kwekushanda. Simbisa nguva dzose uye zvisina kujairika patrol midziyo yekuongorora.Mumamiriro ezvinhu akajairika, vashandi vanofanirwa kutarisa jenareta kabhoni brashi kaviri pazuva (kamwe chete mangwanani uye kamwe chete masikati), uye kuyera tembiricha yemuunganidzi ring uye kabhoni brashi neiyo infrared thermometer.Munguva yekuremerwa kwepamusoro muzhizha uye kana reactive simba uye voltage ichichinja zvakanyanya, tembiricha yekuyera nguva ichapfupiswa, uye yakatsiviwa nyowani kabhoni brashi ichave pasi pekuongororwa kwakakosha.Vashandisi vane mamiriro vanofanira kugara vachiyera tembiricha yemuunganidzi mhete uye kabhoni brashi ine infrared thermometer.Rekodha mamiriro ekushanda emidziyo yekuongorora patrol.

B. Gadzirisa uye tsiva. Tarisa uye gamuchira kabhoni ichangobva kutengwa brashi.Edza kukosha kwekupokana kwekabhoni bhurashi uye kupikisa kubata kwekabhoni brashi lead.Iko kukosha kwekupokana kunoenderana nemugadziri uye yenyika zviyero.Nyatsobata maitiro ekutsiva kabhoni mabhurashi.Mabhurashi ekabhoni anoshandiswa muchikamu chimwe chete anofanirwa kuenderana uye haagone kusanganiswa.Usati watsiva kabhoni brashi, nyatsokuya kabhoni bhurashi kuti iite kumeso kwayo.Panofanira kuva nemukaha we 0.2 - 0.4mm muchibatiso chebhurashi, uye bhurasho rinogona kufamba kumusoro nekudzika zvakasununguka mumubati webhurashi.Nharaunda pakati pemucheto wezasi webrashi inobata uye nzvimbo yekushanda ye commutator ndeye 2-3mm.Kana chinhambwe chiri chidiki kwazvo, chinodhumhana nepamusoro pe commutator uye zviri nyore kukuvara.Kana chinhambwe chakakurisa, bhurasho remagetsi riri nyore kusvetuka uye kuburitsa sparks.Edza kuita kuti nzvimbo yekusangana yekabhoni brashi iwedzere kupfuura 80% yechikamu chemuchinjiko wekabhoni brashi.Tsiva kazhinji, asi mabhurashi ekabhoni haafanire kutsiviwa kakawanda.Huwandu hwemabhurashi ekabhoni akatsiviwa panguva imwe chete haafanire kudarika 10% yehuwandu hwemapango mamwe.Iyo kabhoni bhurashi iyo kumusoro kwayo kwakadzikira 3mm pane pamusoro pechibatiso chebhurashi ichatsiviwa nekukasira.Nguva imwe neimwe iyo carbon brush inotsiviwa, carbon brush yemuenzaniso mumwechete inofanira kushandiswa, asi teerera kuchengetedza uye kushandisa zvizere carbon brush.Iyo kabhoni brashi mushure mekutsiva inofanira kuyerwa neDC caliper mita, uye tembiricha bvunzo ichaitwa neiyo infrared thermometer kudzivirira yega kabhoni mabhurashi kubva pakupisa nekuda kwekuwedzeredza.Kune matambudziko ari pachena emidziyo senge protrusion uye kuora mwoyo kwekutsvedza mhete kana commutator commutator commutator, mukana wekugadzirisa unit uchashandiswa kumhanyisa uye kutendeuka nekukuya.Simbisa hutano hwekuchengetedza uye kudzora kwekushanda kudzivirira kubuda kweturbine mafuta painounganidzira mhete panguva yekushanda kweyuniti nekuda kwekusagadzikana kwehutano hwekuchengetedza kana kusarongeka kwekushanda, uye kuwedzera kupikisa kwekubatana pakati pekabhoni brashi uye mhete yekuunganidza.Iyo brashi inobata uye brashi inobata ichanyatso kugadziridzwa panguva huru uye diki gadziriso yeyuniti.Paunenge uchidzosa uye nekuisa bhurashi inobata, kona uye geometric chinzvimbo chichava muchimiro chepakutanga, uye kutsvedza kumucheto uye kutsvedza kunze kumucheto kwekabhoni bhurasho kunofanirwa kuenderana kune inofambisa.

C. Kuchengetedza nguva dzose. Geza kazhinji uye chengetedza nzvimbo yakatsetseka yekabhoni brashi uye commutator slip ring yakachena.Mumamiriro ekunze ane mhepo, inofanira kucheneswa nenguva.Gadzirisa kudzvanywa kwechirimo kazhinji.Kudzvanywa kwekabhoni brashi chitubu kuchaenderana nemirairo ye mugadziri jenareta kugadzira carbon brush bere yunifomu pressure.Dzivirira mabhurashi ega ega ega kubva pakupisa kana kupisa, uye bhurashi mabhurashi kubva pakupisa.Matambudziko mukushanda kwekabhoni mabhurashi anofanirwa kubviswa nenguva kuti adzivise hutsinye uye kuisa mungozi kushanda kwakajairika kweyuniti.Mabhurashi ekabhoni anoshandiswa muchikamu chimwe chete anofanirwa kuenderana uye haagone kusanganiswa.Vashandi vekuchengetedza vanofanira kunyanya kuchenjerera panguva yekuongorora nekugadzirisa.Bvudzi rakarukwa richaiswa muheti uye macuffs achasungirirwa kudzivirira zvipfeko uye zvekupukuta kubva pakurembera nemushini.Paunenge uchishanda, mira pane insulating pad uye usabata matanda maviri kana danda rimwe uye chikamu chepasi panguva imwe chete, uyewo vanhu vaviri havashande panguva imwe chete.Iyo technician inofanirwa kuve neruzivo mukugadzirisa uye kuchenesa inotsvedza mhete yemota.
