Nzira yekutarisa jenareta yekushanda kumba?
Imwe yenzvimbo dzinotungamira mune runyorwa rwezvakajairwa kusashanda zvakanaka kwemotokari masisitimu inogarwa nekuputsika kwemidziyo yemagetsi. Zvinhu zvinonyanya kukosha zvekuvimbisa kushanda kwemidziyo yemagetsi ibheteri uye jenareta, iyo inoshanda pamwe chete mukubatana nguva dzose.
Pane yedu Vodi.su portal, takadzokorora kutaura nezve chimiro chebhatiri uye jenareta, nezve kuparara kwavo uye nzira dzekuongorora. Muchinyorwa chemazuva ano, ndinoda kubata pane imwe nyaya isati yavharwa pane yedu sosi: maitiro ekutarisa jenareta yemota yako kuti ishande kumba?
Izvo zvakajairika kuputsika kwejenareta uye kuratidzwa kwavo
Jenareta, kazhinji, ine zvikamu zvemagetsi uye zvemagetsi. Saka, sezvatakanyora pakutanga, alternator pulley inodzingwa kubva ku crankshaft kuburikidza nebhandi renguva. Saizvozvo, iyo pulley inogona kutadza nekufamba kwenguva, uye kazhinji ndiyo inotsemuka. Chiratidzo chekuputsika kwakadaro kuchava squeak kubva kune injini, bhanhire rinotsvedza, uye kudonha kwemagetsi mumambure.
Chikamu chemagetsi chegungano chine zvikamu zvinotevera:
- rotor uye stator;
- rectifier diodes;
- voltage regulator;
- gungano rebhurashi nema graphite mabhurashi ari kusangana ne rotor zvindori;
- diode zambuko.
Kazhinji kazhinji, varidzi vemotokari vanofanirwa kushandura mabhurashi alternator, ayo anopera. Izvo zvinodiwawo kutarisa kutendeseka kwewaya uye vanobatika. Nekuda kwekupfeka pane rotor shaft inotakura uye yakasununguka bracket fastenings, unogona kuona rotor ichirova matanda e stator.
Zviratidzo zvekuputsika muchikamu che electromechanical zvinogona kuva zvinotevera zviitiko:
- iyo alternator inotumira kuchaja ikozvino kune bhatiri, asi bhatiri haina kukwana zvakakwana;
- nguva dzose kupenya kwebhatiri yekuchaja chiedza;
- kuderedza voltage;
- mwenje wepamberi unopenya zvishoma;
- zvikabudura zvemagetsi, nezvimwewo.
Zviri pachena kuti zviratidzo zviri pachena zvakadaro zvekusashanda zvakanaka hazvigoni kuregeredzwa. Kana matanho akasatorwa nenguva, mhedzisiro inogona kuve yakanyanya kuomarara, kusvika pakubatidza waya uye kushandura mota yako kuita gomo resimbi yakapwanyika. Isu takatonyora paVodi.su nezve maitiro ekutarisa jenareta pasina kuibvisa. Nhasi tichataura nezve nzira dzekutarisa kuita kwayo kumba.
Kutarisa jenareta rakabviswa
Kana ruzivo rwako rweinjiniya yemagetsi rwuri padanho rechikoro chepamusoro, zviri nani kupa basa iri kune nyanzvi.
Chinhu chekutanga chekutarisa kupfeka kwebrashi. Vanogona kupfeka zvose nekuda kwezvikonzero zvechisikigo uye nekuda kwekukanganisa kwe rotor shaft. Pamuenzaniso wega wega wemotokari, mirairo yejenereta inofanira kuratidza hurefu hudiki hwemabhurashi. Kana yakaderera, saka inguva yekuchinja mabhurashi. Chero chitoro chezvikamu zvemotokari chinotengesa seti yemabhurashi ane zvitubu uye zvindori zvinotsvedza.
Nhanho inosungirwa yekuongorora ndeyekuyera stator, rotor uye diode bhiriji windings ine multimeter. Chinja iyo tester kune ohmmeter modhi uye batanidza maprobes ayo kune zvakabuda zveimwe neimwe yemapureti anomonereka. Chiyero chekupikisa chinofanira kunge chiri mukati me 0,2 ohms. Kana yakakwirira kana yakaderera, ipapo mhepo inofanira kuchinjwa. Kupokana pakati peyakajairwa terminal yegungano re stator uye imwe yemapuleti emhepo echishandiso chinoshanda inotenderedza 0,3 Ohm.
Kuongorora rotor kwakanyanya kuoma.
Matanho ekuongorora:
- tinoendesa tester kune yekudzivirira kuyerwa kwemaitiro uye kuyera iyo pakupikisa mhepo yegungano rotor;
- kana iyi parameter iri muhuwandu hwe 2,3-5 ohms, saka zvinhu zvose zvakanaka nemhepo inoputika, hapana kupindirana kwepakati pfupi kana kuzarura mazita;
- kushorwa pasi pemutengo wakatarwa - pane pfupi pfupi;
- kushorwa pamusoro pe5 ohms - kusabatana kwakashata nemhete, kuputsika kwemhepo.
Isa muyedzi mune yezvino diagnostic mode uye isa gumi nemaviri volts (kana 12 kana uri kutarisa alternator yerori) kune inotsvedza mhete. Nenzira yakanaka, mhepo inofadza ye rotor inopedza kwete kupfuura 24 Amps uye kwete pasi pematatu.
Dambudziko ringangovewo rekuzviparadzanisa nevamwe. Kana kupikisa kwekudzivirira kuri mukati mehutano hwemazuva ose, saka mwenje we40-watt incandescent wakabatanidzwa kune mhete uye pasi haufaniri kupisa. Kana ichipenya zvishoma uye ichibwaira, ipapo pane zvinobuda.
Yeuka kuti mabasa ose aya anoitwa mushure mekubviswa kwejenereta uye disassembly yayo. Iyo diode bhiriji inogona kuongororwa zvese pamotokari uye pane yakabviswa jenareta. Izvo zvakakosha zvebvunzo ndeyekuyera simba razvino kana uchibatanidza multimeter probes kune bhiriji terminals uye pasi. Kana iyo voltage iri pamusoro pe 0,5 volts, uye simba remazuva ano riri pamusoro pe 0,5 milliamps, ipapo chimwe chezvinhu zviviri: kune matambudziko nekudzivirira, kana kuti inguva yekuchinja diode.
Vazhinji varidzi vemotokari mugaraji vanogona kuwana yakakosha yekuwedzera probe - clip inoiswa patambo uye inotarisa recoil ikozvino. Ndiyo parameter iyi ine basa rekuchaja bhatiri mota ichifamba. Kana kukosha uku kuri pasi pezviyero zvezita, saka pane dambudziko nejenareta kana diode bridge.
zvakawanikwa
Sezvauri kuona, kuongorora jenareta nenzira yakagadziridzwa harisi basa riri nyore. Pasina midziyo yakakosha, chikonzero chekuputsika chinogona kutsanangurwa chete ne "poke nzira". Matambudziko akafanana anotarisana, kutanga kune vese, nevaridzi vemotokari dzepamba dzakagadzirwa mu90s yekutanga XNUMXs.
Kana uine motokari ichangobva kutengwa, hatingakurudziri kutarisana nezvikanganiso zvemagetsi iwe pachako, sezvo izvi zvinotungamirira pakurasikirwa kwakajeka kwewaranti. Teerera kune zvisimbiso zviri paimba yejenareta. Haugoni kuvakuvadza. Zviri nyore kuendesa chichemo kuchitoro kwawakatenga mudziyo. Kana jenareta ichiri pasi pewaranti, unofanira kuitsiva kana kukanganisa kwefekitari kunowanikwa.
