Maitiro ekutarisa jenareta
Zviri mukati
Iyo jenareta yemuchina ndiyo sosi yesimba mu-on-board network, uye kana ikasashanda kana kutadza, haugone kutyaira kwenguva yakareba pabhatiri rimwe. Ndicho chikonzero nei zvakakosha kutarisa kushanda kwejenareta.
Muzviitiko zvakawanda, hazvizove zvakaoma kutarisa jenereta yemotokari nemaoko ako, nokuti pasinei nemotokari yaunotarisa, nheyo yacho yakafanana. Asi zvakadaro, varidzi vakawanda vemotokari vanowanzoshamisika: sei kutarisa jenareta ne multimeter kana nzira dzakagadziriswa?
zvino tichazoongorora zvakadzama maitiro ekutarisa jenareta mumamiriro egaraji pasina akakosha anomira anoshandiswa mumasevhisi.
Nzira yekutarisa jenareta pasina kuibvisa kubva mumotokari
Pane nzira mbiri, kushandisa multimeter uye pasina zvachose. Yekutanga, ichangoburwa, ndeyekutarisa voltage pamabhatiri, uye yechipiri, yekare uye yakaratidza, inenge yakapesana - iyo bhatiri terminal inofanira kubviswa apo injini inopisa yemukati iri kushanda.
- Kutarisa bhatiri ne multimeter kutanga kunoitika pakuzorora - iyo voltage inofanira kunge iri pakati pe 12.5-12.8 V. Ipapo iwe unofanirwa kuyera kuverenga kwatova pane inomhanya mukati memoto injini, kana 13.8-14.8 V ichionekwa pa 2 zviuru revolutions, ipapo zvese zvakarongeka. . Mhedziso inoramba iripo tarisa voltage pasi pemutoro, kureva, nekubatanidza vatengi - chitofu, magetsi, kupisa, redhiyo tepi rekodhi. Kunyura muhuwandu hwe13,6-13,8 V kunoonekwa sekugamuchirwa, uye kana kuverenga kwakaderera, izvi zvinoratidza kuparara.
- Nzira yechipiri, kufanana nevakawanda "sekuru", iri nyore uye isina matambudziko, asi panguva imwe chete zvine ngozi uye zvinoda kutarisirwa. Maererano nezvinopomerwa, inoshanda paVAZs uye pamotokari itsva, seAveo. Chii chiripo - sunungura bhaudhi reiyo isina kunaka terminal yebhatiri nekiyi yegumi, tanga injini yekupisa mukati uye upe mutoro mudiki nekubatidza mumwe wevatengi, semuenzaniso, mwenje. Wobva wabvisa iyo terminal ine injini inomhanya - kana ikasamira uye malights haaperi, ipapo zvese zvakanaka nejenereta, zvikasadaro unogona kuve nechokwadi chekuti yakaputsika. Iwe unofanirwa kuedza nzira iyi panjodzi yako.
Waona kuti pane kuparara, iwe unofanirwa kubvisa uye kutarisa iyo yakabviswa jenareta ine multimeter, girobhu remwenje uye nekuona. Chimwe nechimwe chezvikamu zvayo chinoenderana nekuongororwa zvakasiyana.

Maitiro ekutarisa mabrashi uye kutenderera zvindori
Kutanga, zvindori nemabhurashi zvinotariswa nemeso, uye mamiriro avo anoongororwa. Semuenzaniso, iyo shoma chiyero inoyerwa (min. kureba kwemuunganidzi mabhurashi kwete pasi pe4,5 mm, uye dhayamita yemaminiti yezvindori ndeye 12,8 mm). Mukuwedzera, ivo vanotarisa kuvapo kwekushanda uye miforo.
Mabhurashi akabviswa kubva mugadziriso bhurashi musangano
Alternator rotor inotsvedza zvindori
Maitiro ekutarisa diode Bridge (inogadzirisa)
Diodes inotariswa nekuyera kuramba uye kuona conductivity. Sezvo bhiriji re diode rine mahwendefa maviri, isu tinobva tangotarisa imwe uye ipapo imwe. Muongorori anofanira kuratidza diode conduction mune imwe nzira chete. Iye zvino zvishoma zvakadzama: tinobata tester probe pane "+" terminal, uye neimwe tinotarisa diode inotungamira imwe neimwe, tobva tachinjanisa maprobes (mune imwe nyaya panofanirwa kuve nekupokana kwakawanda, asi kwete mune imwe). Zvadaro, nenzira imwecheteyo, tinoenderera mberi nechimwe chikamu chebhiriji.

Kutarisa masiripi mhete
Imwe chete diode yakaipa inotungamirira kukukundikana kwebhiriji rose re diode uye inopa bhatiri mari shoma.
Maitiro ekutarisa iyo voltage regulator
Regulator inotariswa kana paine undercharging kana overcharging bhatiri. Iyo voltage inoyerwa pamarevolutions, inofanirwa kunge iri pakati pe14,4 - 15V.
Mukuwedzera, iwe unogona kutarisa kushorwa kweiyo regulator capacitor (panguva iyo tester probes yakabatana, inofanira kuderera kusvikira yaita infinity).
Pane yakabviswa jenareta voltage regulator, tarisa mamiriro emabhurashi uye gadzira Kutarisa kushanda ne 12V mwenje girobhu uye nguva dzose voltage. Ndiko kuti, iwe unofanirwa kubatanidza girobhu remwenje kumabhurashi, uye shandisa 12V kune yakanaka terminal uye pasi remugadziri (chiedza chinofanira kunge chiri, uye kubuda kana magetsi akawedzera pamusoro pe15V).
Maitiro ekutarisa iyo stator
Stator winding resistance yakaedzwa pasina diode bhiriji uye pakati pematerminals panofanirwa kunge paine 0,2 ohms, uye pakati petambo isina kwayakarerekera uye inomonereka kusvika 0,3. Hum yakasimba yejenareta panguva yekushanda inoratidza pfupi pfupi mu stator kana bhiriji kutenderera. Mukuwedzera kune cheki yakadaro, zvakakosha kuongorora kuvapo kwekushanda mu stator uye pa rotor.
Maitiro ekutarisa jenareta rotor
Nhanho yekutanga ichave kuenderera kweiyo excitation winding. Kuti uite izvi, pane multimeter, isa modhi yekutarisa kupikisa uye kuyera pakati pezvindori zvinotsvedza - mhepo kuramba. inofanira kuva mukati me2,3-5,1 ohms. Kana yapera, ipapo kungave kuputsa kana kungosangana kwakashata pakati pemhete uye inotenderera inotungamira. Low resistance inoratidza interturn circuit.
Uchishandisa iyo ammeter modhi pane multimeter, unogona zvakare kutarisa ikozvino inopedzwa nemhepo. Izvo zvinodikanwa kuisa 12V kune inotsvedza zvindori uye kuyera munharaunda yakavhurika - iyo excitation winding haifanire kupedza kupfuura 3-4,5 Am.

Stator (mhepo) yejenareta yemotokari
Kune iyo yakazara yakaoma, iwe unogona zvakare kuwedzera muyedzo weiyo rotor insulation kuramba. kuti ubereke izvi, iwe uchada 40-watt girobhu uye waya (imwe waya kubva pachigadziko kusvika kune mhete, uye imwe kuburikidza negirobhu kuenda kumuviri - kana zvese zvakajairika, ipapo girobhu harizovheneke, asi. kana shinda ikasapenya, panobva pabuda mvura yepasi).
Kuomerera kune ese kurudziro uye kutevedzana kwebvunzo, kazhinji, unogona kutarisa zviri nyore jenareta yemota uye kuita kwayo wega, uine imwe chete multimeter yaunayo. Asi kuitira kuti ugadzirise, uchinge wasarudza iyo node yakashata, zvakakosha kutsiva chikamu chakakundikana. Dzora kushushikana kwebhandi, mamiriro evanobatika, tarisa mwenje wejenareta pane dashboard uye jenareta ichagara iwe kwenguva refu.
