Kodi injini ya "teknoloji yakuda" yomwe ili ndi mphamvu zambiri kuposa maginito osowa padziko lapansi?Galimoto "yowonekera" yosakanikirana yosagwirizana!

Dziko lapansi losawerengeka limadziwika kuti "golide wamakampani", ndipo limatha kuphatikizidwa ndi zida zina kuti lipange zida zatsopano zosiyanasiyana zokhala ndi zinthu zosiyanasiyana, zomwe zitha kupititsa patsogolo kwambiri magwiridwe antchito azinthu zina.

Pamene chiwerengero cha nkhokwe zapadziko lapansi zomwe sizipezeka ku China zikucheperachepera, dziko losowa lasanduka gwero lachitetezo cha dziko;migodi yosawerengeka komanso kukonza zinthu mozama kumabweretsa mavuto owononga chilengedwe…

Pamene mutu uwu wa "mtundu wa dziko" unayikidwa patsogolo pa anthu, mabizinesi ambiri anali adakali "pambali", pamene Gree anasankha kugwiritsa ntchito "teknoloji yakuda" kuti atenge "ntchito yofunika".

Mu 1822, Faraday anatsimikizira kuti magetsi akhoza kusinthidwa kukhala kuyenda kozungulira;

Pansi pa chizoloŵezi chosalekeza cha chiphunzitso ichi, jenereta yoyamba ya DC ndi galimoto m'mbiri ya anthu inatuluka;

Siemens adagwiritsa ntchito kuyendetsa magalimoto, kenako adapanga tramu yapadziko lonse lapansi;

Edison adayesanso injini iyi, yomwe idatulutsa mphamvu zamahatchi a trolley…

Masiku ano, ma motors akhala chimodzi mwazinthu zofunika kwambiri pazida zamakina.Komabe, kupanga magalimoto azikhalidwe "ndikosalekanitsidwa ndi dziko losowa".M'makampani opanga magalimoto, kupulumutsa mphamvu ndi kuchepetsa utsi ndikofunikira mwachangu.

"Ndi kusintha kwa chilengedwe, tinayamba kuzindikira kuti udindo wa bizinesi sikungodziwa luso lamakono, komanso kuphatikiza zinthu, chilengedwe, ndi zosowa za moyo wa anthu.Zopangidwa motere ndi zamtengo wapatali. ”——Dong Mingzhu

Chifukwa chake, Gree Kaibon synchronous relucance motor, yomwe sifunikira kugwiritsa ntchito maginito okhazikika, sikudalira zinthu zapadziko lapansi, imapulumutsa ndalama zopangira zinthu, imapewa kuipitsidwa kwachilengedwe komwe kumachitika chifukwa chakukula kwa magawo osowa padziko lapansi, ndipo imayankha kuyitanidwa kwamphamvu kwa dziko. kuteteza ndi kuchepetsa umuna, kunayamba.

The synchronous relucance motor ili ndi katundu wokayikakayika.Imatsatira mfundo yoyendetsera ntchito kuti maginito flux nthawi zonse imatseka panjira yocheperako.Makokedwewo amapangidwa ndi kukoka kwa maginito komwe kumapangidwa ndi kusintha kwa kusafuna komwe kumachitika chifukwa cha rotor pamalo osiyanasiyana.Ndi magwiridwe antchito apamwamba komanso otsika mtengo, Ubwino wopulumutsa mphamvu umawonekera m'magulu ambiri agalimoto.

Synchronous kusafuna mota VS yachikhalidwe DC mota: palibe maburashi ndi mphete, zosavuta komanso zodalirika, kukonza kosavuta;

Synchronous relucance motor VS yachikhalidwe AC asynchronous motor: Palibe mafunde pa rotor, kotero palibe kutayika kwa mkuwa kwa rotor, komwe kumathandizira kuyendetsa bwino kwa mota;

Synchronous relucance motor VS switched reluctance motor: Pamwamba pa rotor ndi yosalala ndipo kusintha kwamakasitomala kumakhala kosalekeza, komwe kumapewa zovuta za torque ripple ndi phokoso lalikulu panthawi yogwiritsa ntchito motayitsa kukana;nthawi yomweyo, stator ndi sine yoweyula maginito munda, amene ndi yosavuta kulamulira ndi hardware nsanja Kukhwima, potero kuchepetsa mtengo wa dongosolo pagalimoto kulamulira;

Synchronous relucance motor VS industrial darling - okhazikika maginito synchronous motor: palibe maginito okhazikika pa rotor, mtengo wake ndi wotsika, imathetsa vuto la kufooka kwamunda ndi kutayika kwa maginito, kugwiritsa ntchito nthawi yayitali, kugwira ntchito bwino kumakhala kokhazikika, ndipo palibe zofunikira zokhwima pa voliyumu ndi kulemera kwake Mwambowu ukhoza kusinthiratu injini yokhazikika ya maginito synchronous motor.

Kupyolera mu kafukufuku wodziyimira pawokha komanso chitukuko, Gree adatsogola pakuzindikira ukadaulo waukadaulo wamakina osagwirizana ku China, ndipo adatengera zida zapadera, njira zingapo zowongolera zamagalimoto ndi njira zopangira monga kupanga chitsulo pakati ndi kuphatikiza magalimoto, ndipo pamapeto pake adapeza mwayi wambiri.

1. Kupulumutsa mphamvu ndi kuteteza chilengedwe

The synchronous kukana galimoto kuletsa maginito okhazikika, palibe vuto la kutentha kutentha kwa maginito, ndipo imatha kugwira ntchito mokhazikika pansi pa kutentha kwambiri.Popeza sichifunikira kugwiritsa ntchito maginito okhazikika, sichidalira zinthu zapadziko lapansi zomwe sizikupezeka, imapulumutsa ndalama zopangira zinthu, komanso imapewa kuipitsidwa ndi malo osowa padziko lapansi ku chilengedwe.Yankhani mofunikira ku kuitana kwa dziko lonse kuti kusungidwe mphamvu ndi kuchepetsa utsi.Kuphatikiza apo, rotor ya motor synchronous relucance motor siyenera kuponyedwa aluminium, yomwe imachepetsa kwambiri kugwiritsa ntchito mphamvu popanga.

2. Kuchita bwino

Poyerekeza ndi ma asynchronous motors, ma synchronous relucance motors amagwira bwino kwambiri, ndipo amatha kufikira mphamvu zamagetsi pamwamba pa IE4.Katunduyo amachokera ku 25% mpaka 120% ndi malo ochita bwino kwambiri.Kusintha ma asynchronous motors kapena YVF motors ndi mphamvu zomwezo kumatha kupititsa patsogolo mphamvu zamagetsi ndikupulumutsa mphamvu zamagetsi.Zotsatira zake ndizokwera kwambiri mpaka 30% kapena kupitilira apo.

3. Kuyankha mwachangu

Popeza palibe mipiringidzo ya gologolo khola ndi maginito pa rotor, ndi lalikulu-dera maginito chotchinga kagawo mu rotor kukhomerera chidutswa, rotor wa synchronous kukana galimoto ali ndi mphindi yaing'ono inertia.Pansi pazidziwitso zomwezo, mphindi ya inertia ya motor synchronous relucance motor ndi pafupifupi 30% yokha ya injini ya asynchronous.Panthawi zomwe zimafunikira kuyankha mwachangu kwambiri, monga ma extruder, zimatha kuchepetsa kuchuluka kwamafuta ambiri agalimoto, kuchepetsa ma module apano a inverter, ndikupulumutsa mphamvu.Ndalama zogwiritsira ntchito pamene akufulumizitsa kupanga.

4. Kusinthasintha kwabwino

Ma synchronous relucance motor amagwiritsa ntchito casing wamba wa IEC (aluminiyamu kapena chitsulo chotayira angagwiritsidwe ntchito malinga ndi zosowa za ogwiritsa), ndipo miyeso yoyikayo imatanthawuza mawonekedwe a IEC.Pakuti mkulu mphamvu kachulukidwe synchronous kusafuna galimoto, popeza chimango kukula ndi 1-2 ang'onoang'ono kuposa muyezo atatu gawo asynchronous galimoto, voliyumu yafupika ndi oposa 1/3, amene mosavuta makonda malinga ndi zosowa za makasitomala (kukhazikitsa zosiyanasiyana njira, Kunja chipangizo mawonekedwe kapangidwe), mwachindunji m'malo galimoto choyambirira.

5. Kutentha kochepa kumakwera

Popeza kuti injini ya synchronous reluctance imasungabe kutaya pang'ono kwa rotor ikathamanga pamagetsi ovotera, kukwera kwa kutentha kumakhala kwakukulu.Imatha kupitiliza kugwira ntchito kwa torque mkati mwa liwiro la 10% -100%, ndipo imatha kuloleza kugwira ntchito mochulukira nthawi 1.2, yomwe imagwiranso ntchito pakuzizira kozizira.

6. Kudalirika kwakukulu komanso kukonza kosavuta

Rotor ilibe chiwopsezo cha demagnetization, kutayika pang'ono, ndi kutentha kwapang'onopang'ono, kuonetsetsa kukhazikika kwa nthawi yayitali kwa dongosolo lopaka mafuta ndikuwonjezera moyo wamagetsi;nthawi yomweyo, rotor ndi yopepuka kulemera, yosavuta kusokoneza ndi kusonkhanitsa, komanso yotetezeka kusunga.Kulimbana mosavuta ndi malo ovuta komanso kutentha kwambiri kwa ntchito.

Kuphatikiza apo, muzogwiritsa ntchito monga mapampu ndi mafani omwe amafunikira magwiridwe antchito olemetsa pang'ono, ma synchronous relucance motors amagwirizana kwambiri ndi zosowa za ogwiritsa ntchito pakusunga mphamvu ndi kuchepetsa kutulutsa.

Pakali pano, Kaibang wafunsira ma patent oposa 20 pa synchronous kusafuna galimoto ndi luso kulamulira, ndipo anazindikira chiwerengero chachikulu cha mankhwala, ndi zizindikiro luso kuposa mankhwala mpikisano mayiko.

Akatswiri ena ananenapo kuti: “M’dziko lathu mulibe vuto la chitetezo chambiri.Kodi zikuyenera kugwirizana ndi msika wapadziko lonse lapansi ndikutengera njira ya 'kuchotsa ukadaulo wapadziko lonse lapansi' pogwiritsa ntchito ma motors osagwirizana?Kapena mugwiritse ntchito mokwanira ubwino wa dziko lapansi losawerengeka kuti muwongolere mtengo wa zinthu?”

Gree amapereka yankho - "kupanga thambo bluer ndi dziko lapansi kubiriwira", ndi mosalekeza kulima ndi kuchita bwino mu synchronous kukana luso galimoto, chifukwa mphamvu yopulumutsa ndi kuchepetsa umuna si nkhani ya dziko, ndi zambiri za moyo uliwonse padziko lapansi.moyo.Uwu ndi udindo wa dziko lalikulu komanso udindo wa bizinesi.
