Sunthani manja anu ang'onoang'ono ndikukhala kutali ndi zolephera zokhumudwitsa zamagalimoto?
1. Galimoto siyingayambitsidwe
1. Galimoto sitembenuka ndipo palibe phokoso.Chifukwa chake ndi chakuti pali gawo lotseguka la magawo awiri kapena atatu mumagetsi amagetsi kapena mafunde.Yang'anani koyamba za voteji.Ngati palibe magetsi mu magawo atatu, vuto liri mu dera;ngati ma voltages a magawo atatu ali oyenerera, vuto liri mu injini yokha.Panthawiyi, kukana kwa magawo atatu a ma windings a injini kungayesedwe kuti mudziwe mafunde omwe ali ndi gawo lotseguka.
2. Galimoto sitembenuka, koma pali phokoso la "kung'ung'udza".Yezerani choyimira chamoto, ngati voteji ya magawo atatu ili yoyenera ndipo mtengo wake ukhoza kuonedwa ngati wolemetsa kwambiri.
Masitepe oyendera ndi awa: choyamba chotsani katunduyo, ngati liwiro ndi phokoso la galimoto zili zachilendo, zikhoza kuganiziridwa kuti kulemetsa kapena gawo la makina la katundu ndilolakwika.Ngati sichikutembenukirabe, mutha kutembenuza shaft yamoto ndi dzanja.Ngati ili yothina kwambiri kapena silingatembenuke, yesani mphamvu ya magawo atatu.Ngati mphamvu ya magawo atatu ili yoyenera, koma ndi yayikulu kuposa mtengo wake, zitha kukhala kuti gawo lamakina agalimoto latsekeredwa ndi mota Kupanda mafuta, kunyamula dzimbiri kapena kuwonongeka kwakukulu, chivundikiro chomaliza kapena chivundikiro chamafuta ndi. imayikidwa mozungulira kwambiri, rotor ndi zamkati zimawombana (zomwe zimatchedwanso kusesa).Ngati kuli kovuta kutembenuza shaft ya injini ndi dzanja ku ngodya inayake kapena ngati mukumva phokoso la "chacha" nthawi ndi nthawi, lingaganizidwe ngati kusesa.
Zifukwa zake ndi:
(1) Kusiyana pakati pa mphete zamkati ndi zakunja za zonyamula ndi zazikulu kwambiri, ndipo mayendedwe ayenera kusinthidwa.
(2) Chipinda chonyamulira (bowo) ndi chachikulu kwambiri, ndipo dzenje lamkati ndi lalikulu kwambiri chifukwa chakuvala kwanthawi yayitali.Njira yadzidzidzi ndikuyika chitsulo chosanjikiza kapena kuwonjezera manja, kapena kukhomerera tinthu ting'onoting'ono pakhoma la chipinda chonyamulira.
(3) Shaft imapindika ndipo chivundikiro chakumapeto chavala.
3. Galimoto imazungulira pang'onopang'ono ndipo imatsagana ndi phokoso la "kung'ung'udza", ndipo shaft imagwedezeka.Ngati kuyeza kwa gawo limodzi ndi zero, ndipo momwe magawo awiri ena akupitilira kupitilira pakali pano, zikutanthauza kuti ndi ntchito ya magawo awiri.Chifukwa chake ndikuti gawo limodzi la dera kapena magetsi ndi lotseguka kapena gawo limodzi la mafunde amagalimoto ndi lotseguka.
Pamene gawo limodzi la injini yaing'ono yotseguka, ikhoza kufufuzidwa ndi megohmmeter, multimeter kapena nyali ya sukulu.Poyang'ana galimotoyo ndi nyenyezi kapena delta kugwirizana, zolumikizira za magawo atatu ziyenera kupatulidwa, ndipo gawo lililonse liyenera kuyesedwa kuti likhale lotseguka.Ambiri mwa ma windings a sing'anga-mphamvu motors ntchito mawaya angapo ndipo olumikizidwa mu kufanana kuzungulira angapo nthambi.Ndizovuta kwambiri kuwona ngati mawaya angapo athyoka kapena nthambi yofananira imachotsedwa.Njira yoyendetsera magawo atatu ndi njira yotsutsa imagwiritsidwa ntchito nthawi zambiri.Kawirikawiri, pamene kusiyana pakati pa magawo atatu amakono (kapena kukaniza) kumaposa 5%, gawo lomwe lili ndi mphamvu zochepa (kapena kukana kwakukulu) ndilo gawo lotseguka.
Kuyeserera kwatsimikizira kuti vuto lotseguka la mota nthawi zambiri limapezeka kumapeto kwa mafunde, olowa kapena otsogolera.
2. Fuseyi imawombedwa kapena relay yotenthetsera imachotsedwa poyambira
1. Njira zothetsera mavuto.Yang'anani ngati mphamvu ya fuseyi ndi yoyenera, ngati ili yaying'ono, m'malo mwake ndi yoyenera ndikuyesanso.Ngati fuseyi ikupitiriza kuwomba, fufuzani ngati lamba woyendetsa galimotoyo ndi wothina kwambiri kapena katundu wake ndi waukulu kwambiri, kaya pali kachigawo kakang'ono kozungulira, komanso ngati galimotoyo ndiyofupikitsa kapena yokhazikika.
2. Njira yowunikira zolakwika.Gwiritsani ntchito megohmmeter kuyeza kukana kwamphamvu kwa injini yokhotakhota pansi.Pamene kukana kwa kutchinjiriza kumakhala kotsika kuposa 0.2MΩ, zikutanthauza kuti mapindikidwewo ndi onyowa kwambiri ndipo ayenera kuumitsa.Ngati kukana ndi zero kapena nyali yowunikira ili pafupi ndi kuwala kwabwinobwino, gawolo limakhazikika.Kuyika kwa mafunde nthawi zambiri kumachitika potulukira injini, dzenje lolowera la chingwe chamagetsi kapena polowera cholumikizira.Kwa chomalizachi, ngati chikapezeka kuti vuto la pansi silili lalikulu, nsungwi kapena pepala lotetezera likhoza kuikidwa pakati pa stator core ndi mafunde.Pambuyo potsimikizira kuti palibe maziko, akhoza kukulungidwa, kujambula ndi utoto wotsekemera ndi zouma, ndikupitirizabe kugwiritsidwa ntchito pambuyo podutsa kuyendera.
3. Njira yoyang'anira pakuwongolera zolakwika zafupipafupi.Gwiritsani ntchito megohmmeter kapena multimeter kuyeza kukana kwa insulation pakati pa magawo awiri aliwonse pamizere yolumikizira yosiyana.Ngati ili pafupi ndi zero pansi pa 0.2Mf, zikutanthauza kuti ndi dera lalifupi pakati pa magawo.Yezerani mafunde a ma windings atatu motsatana, gawo lomwe lili ndi mphamvu yayikulu kwambiri ndi gawo lalifupi, ndipo chowunikira chachifupi chingagwiritsidwenso ntchito kuyang'ana ma interphase ndi inter-turn short circuits of the windings.
4. Chiweruzo njira ya stator yokhotakhota mutu ndi mchira.Pokonza ndikuyang'ana galimotoyo, ndikofunikira kuti muwunikirenso mutu ndi mchira wa stator wokhotakhota wa injini pamene chotulukacho chikuphwanyidwa ndikuiwalika kuti chilembedwe kapena chizindikiro choyambirira chatayika.Nthawi zambiri, njira yoyendera yotsalira ya maginito, njira yowunikira, njira yowonetsera diode ndi njira yotsimikizira mzere wosinthira ingagwiritsidwe ntchito.Njira zingapo zoyambirira zonse zimafuna zida zina, ndipo woyezerayo ayenera kukhala ndi chidziwitso chothandiza.Lamulo lotsimikizira mwachindunji la kusintha mutu wa ulusi ndi losavuta, ndipo ndilotetezeka, lodalirika komanso lodziwika bwino.Gwiritsani ntchito ohm block ya multimeter kuti muyese mawaya awiri omwe ali gawo limodzi, ndiyeno ikani chizindikiro pamutu ndi mchira wa stator yokhotakhota.Mitu itatu (kapena michira itatu) ya manambala olembedwa imalumikizidwa ndi dera motsatana, ndipo michira itatu yotsalira (kapena mitu itatu) imalumikizidwa palimodzi.Yambani injini popanda katundu.Ngati kuyambika kuli pang'onopang'ono ndipo phokoso liri lokwera kwambiri, zikutanthauza kuti mutu ndi mchira wa gawo limodzi lokhotakhota zimasinthidwa.Panthawiyi, mphamvuyo iyenera kudulidwa nthawi yomweyo, malo a cholumikizira cha gawo limodzi ayenera kusinthidwa, ndiyeno mphamvu iyenera kutsegulidwa.Ngati idakali yofanana, zikutanthauza kuti gawo losinthira silinatembenuzidwe.Bwezerani mutu ndi mchira wa gawoli, ndikusintha magawo ena awiri motsatizana mofanana mpaka phokoso loyambira la galimoto likhale lachilendo.Njirayi ndi yophweka, koma iyenera kugwiritsidwa ntchito pamakina ang'onoang'ono ndi apakatikati omwe amalola kuyambira molunjika.Njirayi singagwiritsidwe ntchito kwa ma motors omwe ali ndi mphamvu zazikulu zomwe sizilola kuyambika kwachindunji.
