Jenereta yamagalimoto.
Jenereta ya galimoto ndiyo mphamvu yaikulu ya galimoto, ntchito yake ndi kupereka mphamvu ku zipangizo zonse zamagetsi (kupatulapo zoyambira) pamene injini ikuyenda bwino, ndi kulipiritsa batire nthawi yomweyo.
Pamaziko a wamba alternator magawo atatu stator mapiringidzo, kuonjezera chiwerengero cha makhoti mokhotakhota ndi kutsogolera terminal, kuwonjezera ya magawo atatu mlatho rectifier. Pa liwiro lotsika, mapindikidwe oyambira ndi mapiritsi owonjezera amatuluka motsatizana, ndipo pa liwiro lalikulu, mapindikidwe a magawo atatu okha ndiwo amatuluka.
Mfundo yogwira ntchito
Mfundo ntchito alternator lonse
Pamene dera kunja energizes munda wokhotakhota mwa burashi, ndi maginito kwaiye, kuti claw mzati ndi magnetized mu N pole ndi S pole. Rotor ikazungulira, kusinthasintha kwa maginito kumasintha mosinthana ndi mafunde a stator, malinga ndi mfundo ya ma elekitiromagineti induction, mafunde a magawo atatu a stator amatulutsa mphamvu yosinthira ma elekitirodi. Umu ndi momwe alternator imapangira magetsi.
Woyendetsa wamkulu (ie injini) amakoka DC okondwa synchronous jenereta rotor kuti azungulire pa liwiro n(rpm), ndi magawo atatu stator mapiringidzo induction induction AC kuthekera. Ngati mafunde a stator alumikizidwa ndi katundu wamagetsi, mota imakhala ndi mphamvu ya AC, ndipo mphamvu ya AC imasinthidwa kukhala yachindunji kuchokera pagawo lotulutsa kudzera pamlatho wokonzanso mkati mwa jenereta.
Alternator lagawidwa m'magawo awiri a stator yokhotakhota ndi yozungulira yokhotakhota, atatu gawo stator yokhotakhota amafalitsidwa pa chipolopolo monga magetsi Angle 120 madigiri kusiyana wina ndi mzake, wozungulira wokhotakhota wapangidwa ndi zikhadabo ziwiri mzati. Pamene mapiringidzo a rotor akugwirizanitsidwa ndi kulunjika panopa, amasangalala, ndipo zikhadabo ziwiri zamtengowo zimapanga N pole ndi S pole. Mzere wa maginito umayambira pa N pole, umalowa pakati pa stator kupyolera mu mpweya wa mpweya ndikubwerera ku S pole yoyandikana nayo. Kamodzi kozungulira kozungulira, kuzungulira kwa koloko kumadula mzere wa mphamvu ya maginito, ndikupanga mphamvu ya sinusoidal electromotive ndi kusiyana kwa madigiri 120 amagetsi Angle mu mafunde a stator, ndiko kuti, magawo atatu osinthasintha, ndiyeno kupyolera mu chinthu chokonzanso chopangidwa. ma diode kukhala otuluka mwachindunji.
Pamene chosinthira chatsekedwa, batire limapereka kaye panopa. Dera ndi:
Battery positive → kuwala kwacharge → chowongolera → kusangalatsa kokhotakhota → lap iron → batire alibe. Panthawiyi, chowunikira chowunikira chidzawunikira chifukwa chakudutsa komweku.
Komabe, injini ikayamba, pamene liwiro la jenereta likuwonjezeka, mphamvu yamagetsi ya jenereta imakulanso. Pamene voteji linanena bungwe la jenereta ndi wofanana ndi voteji batire, kuthekera kwa "B" mapeto ndi "D" mapeto a jenereta ndi ofanana, pa nthawi ino, nazipereka chizindikiro kuwala kuzimitsidwa chifukwa kusiyana zotheka pakati pa awiriwa. mapeto ndi zero. Zimasonyeza kuti jenereta ikugwira ntchito bwino ndipo mphamvu yosangalatsa imaperekedwa ndi jenereta yokha. Mphamvu yama electromotive ya magawo atatu a AC yopangidwa ndi magawo atatu amagetsi mu jenereta imakonzedwanso ndi diode ndikutulutsa mwachindunji kuti ipereke mphamvu ku katundu ndikulipiritsa batire.
Alternator nthawi zambiri imakhala ndi magawo anayi: rotor, stator, rectifier ndi cap cap.
(1) Rota
Ntchito ya rotor ndikupanga maginito ozungulira.
Rotor imakhala ndi mzati wa claw, goli, maginito ozungulira maginito, mphete yosonkhanitsa ndi shaft yozungulira.
Mitengo iwiri ya zikhadabo imapanikizidwa pa shaft yozungulira, ndipo iliyonse ya zikhadabo ziwirizo imakhala ndi mitengo isanu ndi umodzi ya milomo ya mbalame. Kuzungulira kwa maginito (koyilo ya rotor) ndi goli la maginito zimakonzedwa m'kati mwa phazi.
Mphete yotolera imakhala ndi mphete ziwiri zamkuwa zotsekeredwa kuchokera kwa wina ndi mnzake. Mphete yosonkhanitsa imapanikizidwa pa shaft ya rotor ndikutsekeredwa ndi shaft. Mphete ziwiri zosonkhanitsazo zimalumikizidwa ku malekezero onse a maginito a maginito.
Pamene mphete ziwiri zosonkhanitsa zimadutsa mumtsinje wachindunji (kupyolera mu burashi), pali panopa kupyolera mu mphamvu ya maginito, ndipo maginito a axial maginito amapangidwa, kotero kuti mzati umodzi umakhala ndi magnetized ku N pole ndipo winayo ndi magnetized. ku S pole, motero kupanga mapeyala asanu ndi limodzi a mitengo ya maginito yodutsana. Pamene rotor imazungulira, mphamvu ya maginito yozungulira imapangidwa [1].
Kuzungulira kwa maginito kwa alternator ndi: goli → N pole → kusiyana kwa mpweya pakati pa rotor ndi stator → stator → Kusiyana kwa mpweya pakati pa stator ndi rotor → S pole → goli.
(2) Chiyerekezo
Ntchito ya stator ndi kupanga alternating current.
The stator ili ndi stator pachimake ndi stator koyilo.
Pakatikati pa stator amapangidwa ndi zitsulo zachitsulo za silicon zokhala ndi ma grooves mkati mwa mphete yamkati, ndipo woyendetsa wa stator wolowera amalowetsedwa mu poyambira pachimake.
Mapiritsi a stator ali ndi magawo atatu, ndipo mapindikidwe atatu amatengera kulumikizidwa kwa nyenyezi kapena kulumikizidwa kwa makona atatu (mphamvu yayikulu), yomwe imatha kupanga magawo atatu osinthasintha.
Mapiri a magawo atatu ayenera kuvulazidwa malinga ndi zofunikira zina kuti apeze mafupipafupi, matalikidwe ofanana, kusiyana kwa gawo la 120 ° magawo atatu a electromotive mphamvu.
1. Mtunda wapakati pa mbali ziwiri zogwira mtima za koyilo iliyonse uyenera kukhala wofanana ndi malo okhala ndi mtengo wa maginito.
2. Mtunda wapakati pa nsonga zoyambira zozungulira zozungulira za gawo lililonse uyenera kukhala wofanana kapena kuchulukitsa kwa mtunda wokhala ndi mitengo ya maginito.
3. Mphepete mwa mafunde a magawo atatu ayenera kulekanitsidwa ndi 2π + 120o Angle yamagetsi (malo ogwiritsidwa ntchito ndi mitengo ya maginito ndi 360o Angle yamagetsi).
Mu zoweta JF13 mndandanda alternator, awiri mizati maginito nkhani malo malo 6 mipata (60o magetsi Angle pa kagawo), ndi maginito mzati nkhani malo malo a 3 mipata, kotero malo nthawi ya mbali ziwiri zothandiza. koyilo iliyonse ili ndi mipata 3, mtunda wapakati pa nsonga yoyambira ya gawo lililonse lopindika moyandikana ndi mipata ya koyilo 6, m'mphepete mwa gawo la magawo atatu. kutsekereza kumatha kulekanitsidwa ndi mipata 2, mipata 8, mipata 3. 14 mipata, etc.
(3) Wokonzanso
Ntchito ya alternator rectifier ndikusintha magawo atatu osinthira mafunde a stator kuti akhale olunjika. Wokonzanso wa 6-chubu alternator ndi gawo la magawo atatu a full wave rectifier rectifier wopangidwa ndi 6 silicon rectifier diode, ndipo machubu 6 okonzanso amakanikizidwa (kapena kuwotcherera) pa mbale ziwiri.
1. Mawonekedwe a ma silicon rectifier diode agalimoto
(1) Large ntchito panopa, patsogolo avareji panopa 50A, mafunde panopa 600A;
(2) High n'zosiyana voteji, m'mbuyo kubwereza nsonga voteji 270V, m'mbuyo sanali kubwereza nsonga voteji 300V;
(3) Pali chitsogozo chimodzi chokha. Ndipo machubu ena a diode ndi abwino, ma diode amatsogolera alibe, chubu chokhala ndi mzere wotsogola amatchedwa positive chubu, ndipo chubu chokhala ndi mzere wotsogola woyipa chimatchedwa chubu loyipa, motero diode yowongolera imakhala ndi diode yabwino komanso diode negative.
(4) Chikuto chomaliza
Chivundikiro chomaliza chimagawidwa m'magawo awiri (chivundikiro chakutsogolo ndi chivundikiro chakumbuyo chakumbuyo), chomwe chimagwira ntchito yokonza rotor, stator, rectifier ndi brush assembly. Chophimba chotsirizira nthawi zambiri chimaponyedwa ndi aluminum alloy, chomwe chimatha kuteteza bwino kutayikira kwa maginito ndipo chimakhala ndi ntchito yabwino yochotsa kutentha.
Chivundikiro chakumbuyo chakumbuyo chimaperekedwa ndi msonkhano wa burashi wopangidwa ndi burashi, chotengera burashi ndi kasupe wa burashi. Ntchito ya burashi ndi kuwonetsa magetsi kudzera mu mphete yosonkhanitsa kumunda wokhotakhota.
Kugwirizana pakati pa maginito othamanga (maburashi awiri) ndi jenereta ndizosiyana, kotero kuti jenereta imagawidwa m'mitundu yamkati ndi kunja.
1. Internal lap iron jenereta: Jenereta yokhala ndi maginito okhotakhota burashi yolakwika mwachindunji lap iron (yolumikizidwa mwachindunji ndi nyumbayo).
2. Jenereta yovala kunja: Jenereta momwe maburashi onse a m'munda amakhotakhota amatsekedwa ndi nyumba.
Electrode negative (negative burashi) wa maginito maginito mafunde a kunja chitsulo-mtundu jenereta chikugwirizana ndi owongolera, ndiyeno chitsulo chikugwirizana pambuyo podutsa.
Ngati mukufuna kudziwa zambiri, pitilizani kuwerenga zolemba zina patsamba lino!
Chonde tiyimbireni ngati mukufuna zinthu zotere.
Zhuo Meng Shanghai Auto Co., Ltd. yadzipereka kugulitsa zida zamagalimoto za MG&MAUXS zolandiridwa kuti mugule.
