Injini yamagetsi amphamvu kwambiri
Kawirikawiri amakhulupirira kuti mota yokhala ndi magetsi okwana 3KV ~ 10KV imatchedwamota yamagetsi amphamvu kwambiriMa mota a . 6300V ndi 10000V amagwiritsidwa ntchito kwambiri. Mphamvu ya injini imagwirizana ndi zomwe zimachitika chifukwa cha magetsi ndi magetsi, kotero mphamvu ya mota yamagetsi otsika imawonjezeka mpaka pamlingo winawake (monga 300KW/380V), magetsi oyesedwa adzakhala akulu kwambiri, kutayika kwa mzere kudzakhala kofanana ndi kuwonjezeka kwa magetsi (I^2*r), dera lozungulira la waya limafunika kukhala lalikulu kwambiri, kotero mphamvu yovomerezeka ya chingwe ndi yochepa, ndipo mtengo wake ndi wokwera kwambiri. Pakadali pano, ndikofunikira kuwonjezera magetsi oyendetsedwa kuti mupeze mphamvu zambiri.
Injini yamagetsi otsika
Mota yamagetsi otsika imatanthauza magetsi a AC omwe ali pansi pa 1000V, nthawi zambiri imatanthauza magalimoto a AC 380V, 440V kapena 660V ndi milingo ina ya magetsi.mota zopanda mphamvukwenikweni amagwiritsidwa ntchito pang'ono. Mota yamagetsi otsika imagawidwa m'mitundu iwiri: mota ya AC asynchronous ndi mota ya DC.
Ubwino ndi kuipa kwa ma mota amphamvu kwambiri poyerekeza ndi ma mota amphamvu kwambiri
(1) Ubwino
(1) ikhoza kupangidwa kukhala ndi mphamvu yayikulu, mpaka zikwizikwi kapena masauzande ambiri a kilowatts. Izi zili choncho chifukwa, mu mphamvu yomweyo yotulutsa, mphamvu yamagetsi yamagetsi yapamwamba ikhoza kukhala yaying'ono kwambiri kuposa mota yamagetsi otsika (mosiyana kwambiri ndi mphamvu yamagetsi), mwachitsanzo, 500kW, mphamvu yamagetsi yamagetsi ya 4-pole, mphamvu yamagetsi yovotera ya 380V ya 900A kapena kuposerapo, pomwe mphamvu yamagetsi yovotera ya 10kV ndi 30A yokha kapena kuposerapo. Chifukwa chake, kuzungulira kwa mota yamagetsi okwera kumatha kukhala waya wocheperako. Zotsatira zake, kutayika kwa mkuwa kwa mota yamagetsi okwera kudzakhalanso kochepa kuposa kwa mota yamagetsi otsika. Pama mota amphamvu akuluakulu, kugwiritsa ntchito magetsi otsika, koma chifukwa cha kufunika kwa mawaya okhuthala ndikufunika malo akuluakulu a stator groove, kotero kuti m'mimba mwake wa stator kuti ugwire ntchito yambiri, kukula konse kwa mota kudzakhalanso kwakukulu kwambiri.
② Kwa ma mota akuluakulu, ma mota amphamvu omwe amagwiritsidwa ntchito mu zida zamagetsi ndi zogawa mphamvu ndi zochepa kuposa ndalama zonse mu ma mota amphamvu otsika, ndipo kutayika kwa mzere kumakhala kochepa, kumatha kusunga mphamvu zina. Makamaka, ma mota amphamvu a 10kV, mutha kugwiritsa ntchito mwachindunji ma network power supply (magetsi amphamvu a China omwe amaperekedwa kwa ogwiritsa ntchito nthawi zambiri ndi 10kV), kotero kuti ndalama zomwe zimayikidwa mu zida zamagetsi (makamaka ma transformer) zidzakhala zochepa, kugwiritsa ntchito kosavuta, kulephera kudzakhala kochepa.
(2) Zoyipa
① Mtengo wa kuzunguliza ndi wokwera kwambiri (makamaka chifukwa cha kuphimba kwa zinthu), ndipo mtengo wa zipangizo zotetezera kutentha udzakhalanso wokwera.
(ii) Njira yochizira kutentha kwa moto ndi yovuta kwambiri, ndipo ndalama zogwirira ntchito ndi zokwera.
③ Zofunikira pakugwiritsa ntchito malo ozungulira ndi zovuta kwambiri kuposa za ma mota amagetsi otsika.
Kuyerekeza kusiyana pakati pa mota yamagetsi otsika ndi mota yamagetsi okwera
Kusiyana kwakukulu mu kapangidwe kake
Choyamba, zipangizo zotetezera kutentha kwa coil zimapanga kusiyana, ma mota otsika-voltage, coil makamaka enamel waya kapena zina zotetezera kutentha zosavuta, monga pepala lophatikizana, high-voltage motor insulation nthawi zambiri imagwiritsidwa ntchito mu kapangidwe ka multilayer, monga ufa wa mica tepi, kapangidwe kake ndi kovuta kwambiri, ndipo mphamvu yake ndi yapamwamba kwambiri.
Chachiwiri, kusiyana kwa kapangidwe koziziritsira, ma mota otsika mphamvu amagwiritsa ntchito mafani a coaxial omwe amapumira mwachindunji kuti achotse kutentha, ma mota amphamvu mphamvu zambiri okhala ndi radiator yodziyimira payokha, nthawi zambiri mitundu iwiri ya mafani, seti ya fan yozungulira mkati, seti ya fan yozungulira yakunja, mafani awiri omwe akuyenda nthawi imodzi, kusinthana kwa kutentha pa radiator kudzatulutsidwa kunja kwa kutentha kwa injini.
Chachitatu, kapangidwe ka ma bearing ndi kosiyana, ma mota otsika mphamvu nthawi zambiri amakhala ndi ma bearing asanayambe komanso pambuyo pake, pomwe ma mota amphamvu mphamvu, chifukwa cha katundu wolemera, nthawi zambiri pamakhala ma bearing awiri kumapeto kwa axial, ndipo chiwerengero cha ma bearing kumapeto kosakhala axial chimatsimikiziridwa malinga ndi momwe katundu alili, ndipo makamaka ma mota akuluakulu amagwiritsa ntchito ma bearing otsetsereka.
Kuyerekeza kwa ntchito ya injini ndi mtengo wake
1. Mphamvu yamagetsi ikakwera, mphamvu ya injini imakulanso.
2, kuchuluka kwa magetsi kukakhala kwakukulu, mtengo woyikira umakwera; ngakhale magetsi akukwera, magetsi amagetsi amakhala ochepa, waya ndi chingwe zimatha kusankhidwa kukhala zochepa, koma kufunika kwa ma circuit breakers amphamvu, ma transformer, ma switchgear ndi ndalama zina zamagetsi zikuwonjezekabe mu ndalama zoyambira mumakampani akuluakulu, kotero mabizinesi ang'onoang'ono omwe akumanga nyumba yatsopanoyi ali okonzeka kugwiritsa ntchito zida zamagetsi zochepa.
3, kuchuluka kwa magetsi kukakhala kwakukulu, ndalama zonse zogwirira ntchito zimachepa; mphamvu yaying'ono yochepetsera kutayika kwa magetsi, pamapeto pake ndiyoyenera, zotsatira zake zosungira mphamvu zimakhala zodabwitsa, kotero mabizinesi ambiri akuluakulu pakusintha kwaukadaulo kwa ma mota otsika mphamvu osinthidwa kukhala ma mota amphamvu.
4, mphamvu yamagetsi ikakwera, malo amakhala ambiri; chifukwa pali makabati owongolera mphamvu yamagetsi ndi ena okhalamo.
5, mphamvu yamagetsi ikakwera, mota imakhala yosavuta kuyiyambitsa, mphamvu yoyambira imawonjezeka, yambitsa, lamulira ndi losavuta.
6, mphamvu yamagetsi ikakwera, kayendetsedwe ka ntchito yokonza zinthu kumakhala kovuta; kotero mabizinesi ang'onoang'ono ali okonzeka kugwiritsa ntchito mphamvu yamagetsi yochepa, mabizinesi akuluakulu ali okonzeka kugwiritsa ntchito ma mota amphamvu kwambiri.
