Popanga mafakitale amakono, ma motors amagetsi amagwiritsidwa ntchito kwambiri.Mitundu yosiyanasiyana, mawonekedwe amagetsi ndi ma voliyumu amagetsi amagetsi amatuluka mosalekeza.Zotsatirazi ndizofotokozera mwachidule zifukwa zomwe zimagwirira ntchito limodzi ndi njira zodzitetezera.
Gulu la magalimoto
Ma motors amagetsi amatha kugawidwa kukhala ma mota a DC, ma asynchronous motors ndi ma synchronous motors molingana ndi kapangidwe kake ndi mfundo zogwirira ntchito.Ma synchronous motors amathanso kugawidwa kukhala maginito okhazikika a maginito, ma motors osagwirizana ndi ma hysteresis synchronous motors.Ma Asynchronous motors amatha kugawidwa kukhala ma induction motors ndi AC commutator motors.Ma motors induction amagawidwanso kukhala magawo atatu asynchronous motors, single-gawo asynchronous motors ndi shaded pole asynchronous motors.Ma AC commutator motors amagawidwanso kukhala ma motors agawo limodzi,Ma AC ndi DC omwe ali ndi cholinga chapawiri komanso ma mota othamangitsa.
Zowopsa zomwe zimachitika chifukwa cha gawo limodzi la magawo atatu aasynchronous motors
Magawo atatu asynchronous motors ali ndi njira ziwiri zolumikizira: Y-mtundu ndi Δ-mtundu.Pamene galimoto yolumikizidwa ndi Y ikugwira ntchito mu gawo limodzi, yomwe ili mu gawo lotsekedwa ndi zero.Mafunde a gawo la magawo ena awiriwa amakhala mafunde a mzere.Nthawi yomweyo, imayambitsa zero point drift ndipo gawo lake lamagetsi lidzakweranso.
Pamene mawaya amtundu wa Δ-mtundu watsekedwa mkati, galimotoyo imasintha kukhala V-mtundu wa waya pansi pa mphamvu ya magawo atatu, ndipo magawo awiri akuwonjezeka ndi nthawi 1.5.Pamene mawaya amtundu wa Δ-mtundu amachotsedwa kunja, amafanana ndi mapiritsi a magawo awiri omwe akugwirizanitsidwa mndandanda ndipo gulu lachitatu la ma windings likugwirizanitsidwa mofanana pakati pa ma voltages a mizere iwiri.Mphamvu mu ziwirizokhotakhotaolumikizidwa mu mndandanda amakhalabe osasintha.Zowonjezerapo za gulu lachitatu zidzawonjezedwa ndi nthawi 1.5.
Kufotokozera mwachidule, injini ikagwira ntchito mu gawo limodzi, mafunde ake amakwera kwambiri, ndipo chotchingira ndi chitsulo chowotcha chimatenthetsa mwachangu, kuyatsa zotsekera zomangira ndikuwotcha mafunde agalimoto, zomwe zimakhudza ntchito zopanga.Ngati malo omwe ali pamalowo sali abwino, malo ozungulira adzaunjikana.Pali zinthu zoyaka zomwe zimatha kuyambitsa moto mosavuta komanso kubweretsa zotsatira zoyipa kwambiri.
Zomwe zimayambitsa ntchito yamagalimoto amtundu umodzi komanso njira zodzitetezera
1.Pamene injini singayambe, pamakhala phokoso la phokoso, ndipo chipolopolo chimakhala ndi kutentha kwa kutentha kapena kuthamanga kumachepa kwambiri panthawi yogwira ntchito, ndipo kutentha kumawonjezeka, magetsi ayenera kudulidwa nthawi yomweyo ndipo chifukwa cha kulephera kuyenera kuchitidwa. kupezeka mosamalitsa.Dziwani ngati zomwe zili pamwambazi zimayambitsidwa ndi kusowa kwa gawo.
2.Pamene mzere wamagetsi wa dera lalikulu ndi woonda kwambiri kapena ukukumana ndi kuwonongeka kwa kunja, mphamvu yamagetsi yamagetsi atatu idzayambitsa ntchito ya gawo limodzi chifukwa cha kutentha kwa gawo kapena kugunda kwa kunja.Mphamvu yonyamula yotetezeka ya chingwe chachikulu chamagetsi ndi 1.5 mpaka 2.5 nthawi yomwe idavotera galimotoyo, ndipo mphamvu yonyamula yotetezeka ya chingwe chamagetsi imagwirizana kwambiri ndi njira yoyakira chingwe chamagetsi.Makamaka pamene ikufanana kapena ikudutsana ndi payipi ya kutentha, nthawiyo iyenera kukhala yaikulu kuposa 50cm.Mphamvu yonyamula yotetezeka ya chingwe chamagetsi yomwe imatha kuyenda kwa nthawi yayitali pakukwera kwa kutentha kwa 70 ° C nthawi zambiri imatha kuyang'aniridwa ndi buku la katswiri wamagetsi.Malinga ndi zomwe zinachitikira m'mbuyomu, mphamvu yonyamula mawaya amkuwa ndi 6A pa millimeter imodzi, ndipo mawaya a aluminiyamu ndi 4A pa millimeter imodzi.Komanso, mkuwa-aluminiyamu kusintha olowa ayenera kugwiritsidwa ntchito pamene mkuwa-aluminiyamu olowa waya, kuti kupewa makutidwe ndi okosijeni pakati zipangizo zamkuwa zotayidwa ndi zimakhudza olowa kukana.
3.Kukonzekera kosayenera kwa kusintha kwa mpweya kapena kutsekemera kwa mpweya kungayambitse ntchito ya gawo limodzi la galimoto.Ngati kusintha kwa mpweya kumakhala kochepa kwambiri, kungakhale chifukwa cha mphamvu yamagetsi yomwe imakhala yaikulu kwambiri kuti ipse kukhudzana ndi mkati mwa kusintha kwa mpweya, zomwe zimachititsa kuti gawo la kukhudzana ndi gawo lalikulu kwambiri, ndikupanga gawo limodzi la galimoto.Mphamvu yamagetsi yamagetsi yamagetsi iyenera kukhala 1.5 mpaka 2.5 nthawi yomwe yavotera magetsi.Kuonjezera apo, pakugwira ntchito kwa galimoto, ziyenera kuyang'aniridwa kuti kusintha kwa mpweya kumakhala kochepa kwambiri, kapena ubwino wa mpweya wokhawokha ndi wovuta, ndipo kusintha koyenera kwa mpweya kuyenera kusinthidwa.
4.Mzere wolumikizana pakati pa zigawo zomwe zili mu kabati yolamulira zimatenthedwa, zomwe zingapangitse kuti galimotoyo ikhale yothamanga mu gawo limodzi.Zifukwa zoyatsira chingwe cholumikizira ndi izi:
① Mzere wolumikizira ndi woonda kwambiri, injini ikadzaza kwambiri, imatha kuwotcha chingwe cholumikizira.② Zolumikizira pamapeto onse a mzere wolumikizira sizilumikizana bwino, zomwe zimapangitsa kuti chingwe cholumikizira chiwonjezeke, motero chimawotcha chingwe cholumikizira.Pali zowonongeka zazing'ono zanyama, monga kukwera kwa mbewa pakati pa mizere iwiriyi, kuchititsa kuti kadulidwe kakang'ono pakati pa mizereyo ndikuwotcha chingwe cholumikizira.Yankho lake ndi: musanayambe ntchito iliyonse, kabati yolamulira iyenera kutsegulidwa kuti muwone bwinobwino ngati mtundu wa mzere uliwonse wogwirizanitsa wasintha, komanso ngati khungu lotchinjiriza liri ndi zizindikiro zoyaka.Mzere wamagetsi uli ndi zida zokwanira molingana ndi kuchuluka kwa magalimoto agalimoto, ndipo cholumikizira chimalumikizidwa molingana ndi zofunikira.
Peroration
Pomanga, tiyenera mosamalitsa kutsatira mfundo za njira zosiyanasiyana zomangamanga kuonetsetsa ubwino unsembe.Kukonzekera kwanthawi zonse kwa zida zosiyanasiyana komanso kuyang'anira ndi kukonza nthawi zonse pakugwira ntchito kudzapewa kutayika kosafunikira komanso zoopsa zomwe zimachitika chifukwa cha gawo limodzi lagalimoto.
