Ndi chitukuko chopitilila cha zachuma ndi kutukuka kosalekeza kwa moyo wa anthu, kufunikira kwa mphamvu kukukulirakulira.Panthawi imodzimodziyo, mavuto monga kuwonongeka kwa chilengedwe ndi kusintha kwa nyengo akuchulukirachulukira.Potengera izi, kuwongolera kugwiritsa ntchito mphamvu moyenera komanso kuchepetsa kugwiritsa ntchito mphamvu kwakhala zovuta zofala m'maiko onse.Permanent maginito mota ngati mtundu watsopano, kuchita bwino kwambiri, mota yopulumutsa mphamvu, mphamvu yake yopulumutsa mphamvu yakopa chidwi.Lero tiyang'ana pa mfundo ndi ubwino wa okhazikika maginito Motors, komanso kugawana nanu milandu iwiri yopulumutsa mphamvu Minten otsika-voltage okhazikika maginito Motors m'munda wa zitsulo ndi kuteteza chilengedwe.
Mfundo yaikulu ya injini ya maginito okhazikika
Permanent magnet motor ndi mtundu wa mota yomwe imagwiritsa ntchito kulumikizana pakati pa maginito opangidwa ndi maginito osatha ndi magetsi kuti asinthe mphamvu yamagetsi kukhala mphamvu yamakina.Mapangidwe ake amaphatikizapo maginito osatha, stator ndi rotor.Maginito okhazikika amagwira ntchito ngati maginito amoto ndipo amalumikizana ndi zomwe zikuchitika mu stator koyilo kudzera mugawo lake la maginito kuti apange torque ndi kusamutsa mphamvu zamakina ku rotor, pozindikira kutembenuka kwa mphamvu yamagetsi kukhala mphamvu yamakina.
Poyerekeza ndi motor induction motor, maginito okhazikika ali ndi izi:
1. Kuchita bwino kwambiri: Ma motor induction induction motors ali ndi mphamvu zochepa chifukwa chakuti mphamvu yawo ya maginito imapangidwa ndi panopa mu coil ndipo pali zowonongeka.Pomwe mphamvu yamaginito yamagetsi okhazikika imaperekedwa ndi maginito osatha, omwe amatha kusintha mphamvu zamagetsi kukhala mphamvu zamakina bwino.Malinga ndi maphunziro oyenerera, mphamvu zamagalimoto amagetsi okhazikika akwera pafupifupi 5% mpaka 30% poyerekeza ndi ma motor induction induction.
2. Kuchuluka kwamphamvu kwamphamvu: Mphamvu ya maginito yamagetsi okhazikika ndi apamwamba kuposa a induction motor, motero imakhala ndi mphamvu zambiri.
3. Kupulumutsa mphamvu: Monga maginito okhazikika a maginito ali ndi mphamvu zambiri komanso mphamvu zowonjezera mphamvu, izi zikutanthauza kuti akhoza kutulutsa mphamvu zambiri zamakina ndi mphamvu yolowera yomweyi mu voliyumu yofanana ndi kulemera kwake, motero amazindikira kupulumutsa mphamvu.
M'malo mwa ma motors otsika asynchronous induction motors ndi maginito okhazikika, kuphatikiza kuwongolera magwiridwe antchito komanso kuwongolera pafupipafupi kwa zida zakale komanso zosagwira ntchito zogwiritsa ntchito mphamvu, kumatha kupititsa patsogolo mphamvu zamagetsi zamagetsi, ndi milandu iwiri yotsatirayi. ndizofotokozera.
1: gulu mu Guizhou reel motor transformation project
September 25, 2014 - December 01, 2014, mu anhui mingteng okhazikika maginito electromechanical zida co., LTD ndi gulu ku guizhou nthambi fakitale kujambula waya kujambula msonkhano waya kujambula gawo 29 # molunjika mu waya kujambula makina, 1 #, 2 #, 5 # reel motor energy motility tracking record kufananitsa, anhui mingteng okhazikika maginito mota ndikugwiritsa ntchito ma inverter motors pakuyerekeza kugwiritsa ntchito mphamvu.
(1) Kusanthula kwamalingaliro mayeso asanawonetsedwe mu Gulu 1 pansipa
Table 1
(2) Njira zoyezera ndi ziwerengero zolembedwa ndikuyerekeza motere
Unsembe wa anayi magawo atatu mawaya yogwira mphamvu mita ndi metering chipangizo zokhala ndi thiransifoma panopa, chiŵerengero ndi: okwana mita 1500/5A, No. 5 reel machine sub-mita 100/5A, zomwe zikuwonetsedwa pamamita anayi pakutsata mbiri, kusanthula kwa ziwerengero kuli motere:
Table 2
Chidziwitso: No.1 Reel motor four-pole 55KW, No.2 Reel motor four-pole 45KW, No.5 Reel motor six-pole 45KW
(3) Kuyerekeza kwa ntchito zofanana.
Mu 29 # makina No. 5 chowomba makina (okhazikika maginito synchronous galimoto) ndi No. 6 chowololeza makina (asynchronous galimoto) inverter mphamvu athandizira chipangizo mphamvu mita mlingo 2.0, zonse 600: -/kw-h, yogwira mphamvu mita awiri.Chipangizo cha metering chokhala ndi chiŵerengero chamakono cha thiransifoma 100/5 A. Kuyerekeza kwa ma motors awiri muzochitika zofanana kwambiri zogwirira ntchito za mphamvu zosungidwa zosungirako mphamvu, zotsatira zikuwonetsedwa mu Table 3 pansipa.
Table 3
Zindikirani: Gawoli ndi data yoyezera nthawi yeniyeni, osati kuchuluka kwa makina onse.
(4) kusanthula kwathunthu.
Mwachidule: Kugwiritsa ntchito maginito okhazikika kumakhala ndi mphamvu yayikulu komanso yocheperako kuposa ma inverter motors.Yamuyaya maginito synchronous mota kuposa choyambirira asynchronous motor yogwira mphamvu yopulumutsa mphamvu yawonjezeka ndi 8.52%.

2:Pulogalamu yokonzanso mafani a Centrifugal a kampani yoteteza zachilengedwe
Pulojekitiyi kudzera mu kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake.Kuphatikiza apo, sikuti imangothetsa kukhudzidwa kwamakina pa fani ya centrifugal pomwe mota ikuyamba ndikuchepetsa kulephera kwa fani ya centrifugal, komanso kuwongolera kwathunthu kwa injini kumapititsidwa patsogolo.
(1) Magawo a mota yoyambira asynchronous
(2) Basic magawo okhazikika maginito pafupipafupi kutembenuka galimoto
(3): Kusanthula koyambirira kwamapindu opulumutsa mphamvu
Mafani, mapampu ngati mafakitale, ulimi, moyo wamakina azinthu zambiri, okhala ndi ntchito zambiri, kugwiritsa ntchito mawonekedwe osiyanasiyana, kugwiritsa ntchito mphamvu zake zamagalimoto ndikokulirapo.Malinga ndi ziwerengero, mphamvu yamagetsi yamagetsi idapitilira 60% ya mphamvu yamagetsi yapadziko lonse, pomwe mafani, mapampu amawerengera 10,4%, 20,9% yamagetsi.Chifukwa cha mphamvu ndi zifukwa ndondomeko, dongosolo malamulo ndi ndi m'mbuyo, ambiri mafani ndi mapampu zimayendetsedwa ndi makina interception, otsika dzuwa, oposa theka la mafani ndi mapampu katundu alipo mu magawo osiyanasiyana a zinyalala mphamvu magetsi, mu Kuchulukirachulukira kwamphamvu masiku ano, kuchepetsa zinyalala, kupulumutsa mphamvu zamagetsi kwakhala chinthu chofunikira kwambiri.
Anhui Mingteng wakhala akudzipereka pakupanga ndi kufufuza ndi chitukuko cha maginito amphamvu kwambiri komanso okonda zachilengedwe okhazikika okhazikika, omwe amagwiritsidwa ntchito kwambiri m'mafakitale achitsulo ndi zitsulo, migodi ya malasha, zipangizo zomangira, mphamvu zamagetsi, mafuta a petroleum, makampani opanga mankhwala, mphira, zitsulo, nsalu ndi zina zotero.Otsika-voltage okhazikika maginito motors mu 25% -120% katundu osiyanasiyana, poyerekeza ndi mtundu womwewo asynchronous motor ali ndi dzuwa, otakata ntchito zachuma osiyanasiyana, ndi mphamvu yopulumutsa mphamvu, kuyembekezera mabizinesi ambiri kumvetsa okhazikika maginito motors. , kugwiritsa ntchito maginito okhazikika.
