Electromagnetic yogwira mtima imatha kuyambitsa kusungunuka kwa aluminiyumu popanda kukhudzana, kupanga homogenize kapangidwe ka mankhwala ndi kutentha kwa sungunuka, kuchepetsa mapangidwe a oxide slag, kufupikitsa nthawi yosungunula, kupititsa patsogolo zokolola, komanso kuchepetsa kwambiri ntchito ya ogwira ntchito. Chifukwa cha maubwino ambiri a electromagnetic stirrer, electromagnetic stirrer tsopano yakhala chida chofunikira pamakampani osungunula ndi kuponyera aluminiyamu.

Electromagnetic yogwira mtima imatha kuyambitsa kusungunuka kwa aluminiyumu popanda kukhudzana, kupanga homogenize kapangidwe ka mankhwala ndi kutentha kwa sungunuka, kuchepetsa mapangidwe a oxide slag, kufupikitsa nthawi yosungunula, kupititsa patsogolo zokolola, komanso kuchepetsa kwambiri ntchito ya ogwira ntchito. Chifukwa cha maubwino ambiri a electromagnetic stirrer, electromagnetic stirrer tsopano yakhala chida chofunikira pamakampani osungunula ndi kuponyera aluminiyamu.

Ma electromagnetic stirrer amapangidwa makamaka ndi ma frequency frequency magetsi ndi inductor. Kuphatikizika kwamphamvu kwamagetsi kumatembenuza ma frequency a 50/60Hz osinthira magetsi kukhala gawo la 3-gawo lamagetsi otsika pafupipafupi a 0.5 ~ 5Hz. Mphamvu yamagetsi ikalumikizidwa ndi koyilo ya inductor, gawo loyendayenda la maginito lidzapangidwa. Mphamvu ya maginito yoyendayenda imalowa pansi pa zitsulo zosapanga dzimbiri pansi pa ng'anjo ndi ng'anjo yamoto ndikuchitapo kanthu pa aluminiyamu yosungunuka, kotero kuti aluminiyumu yosungunuka imasuntha nthawi zonse, kuti akwaniritse cholinga chogwedeza. Kukula ndi mayendedwe a mphamvu yokoka kungasinthidwe mwa kusintha voteji, mafupipafupi ndi gawo la magetsi osinthika.

Mphamvu zaposachedwa za AC, DC, AC zosinthika pafupipafupi zokhala ndi ufulu wodziyimira pawokha wopangidwa ndi HuateCompany ndi Nankai University, Shandong University ndi makoleji ena ndi mayunivesite, wapangidwa ndi nduna ulamuliro ndi variable pafupipafupi magetsi nduna kupanga ndi electromagnetic stirrer galimoto dongosolo.

Ukadaulo waposachedwa wa PWM umaphwanya mawonekedwe ogwirizana a frequency converter m'mbuyomu. Malinga ndi mawonekedwe a katundu wa electromagnetic stirrer, mapangidwe apadera a mapulogalamu ndi hardware amachitika. Itha kunyamula katundu wambiri wopatsa mphamvu popanda kuwonjezera kufananiza pakati pa magetsi ndi katundu, ndipo imatha kugwira ntchito pama frequency otsika. Ntchito yokhazikika. Mphamvu zaposachedwa za PWM zosinthika ndizoyenera kugwiritsa ntchito pamagetsi oyendetsa magetsi; poyerekeza ndi chikhalidwe variable pafupipafupi mphamvu magetsi, aposachedwa PWM variable pafupipafupi mphamvu magetsi Huateali ndi izi:

1.Power factor: Mphamvu yamagetsi yamagetsi yaposachedwa ya AC-DC-AC yamagetsi yamagetsi imatha kufika kuposa 0.95, yomwe imagwirizana bwino ndi malamulo adziko lonse a magawo atatu amagetsi (0.9-1). 0.95 kapena apo ndiye yabwino kwambiri. Ngati mphamvu yamagetsi ndiyokwera kwambiri, voteji idzakhala yokwera kwambiri. Poyerekeza ndi magetsi amtundu wa AC-AC, mphamvu yoyika chipangizocho imatha kuchepetsedwa kwambiri.

2.Static ntchito yotayika: Mbali yokonzanso mphamvu yaposachedwa ya PWM AC-DC-AC AC-AC-AC-AC-AC-AC-AC-AC-AC-AC-AC-AC-AC-AC-AC-AC-AC-AC-AC-AC-AC-AC-AC-AC-AC-AC-Frique-Frique-Frique-Friquency imasowa makina owongolera, zida zake sizimatayika pang'ono, ndipo kusinthika kwake ndikwapamwamba kuposa kwanthawi zonse kagawo kakang'ono ka PWM. . Zidazi zikakhala poyimilira, magetsi amtundu wanthawi zonse amafunikira kusinthanitsa mphamvu yayikulu ndi gridi yamagetsi kuti apitilize kukhazikika kwa voliyumu ya mabasi a DC, pomwe magetsi aposachedwa a PWM amakhala opanda mphamvu kusinthanitsa ndi magetsi. gridi yamagetsi. Pankhani ya m'munsi kuposa magetsi chikhalidwe.

3. Kutayika kwa ntchito: Popeza kuti agitator ndi katundu wochititsa chidwi, osati katundu wamtundu wa galimoto, palibe njira yosinthira kuchokera ku mphamvu zamakina kupita ku mphamvu yamagetsi, kotero palibe pafupifupi mphamvu zowonjezera mphamvu panthawi yogwira ntchito. Mphamvu yatsopano ya PWM imazindikira kusinthana kwamagetsi ndi katundu wochititsa chidwi kudzera pamagetsi apakati a DC capacitor, mphamvu yokhayo yomwe ikufunika, ndipo palibe kutembenuka kwa mphamvu, Choncho, magetsi a PWM aposachedwa ali ndi zotayika zochepa zogwirira ntchito kuposa zachikhalidwe. ma frequency frequency magetsi.

4. Ma radiation a Electromagnetic: Chifukwa ma frequency amagetsi a PWM amapangidwa ndi zida zamagetsi zamagetsi ndipo amasinthidwa ndi ma frequency onyamula ma frequency apamwamba, mphamvu zamagetsi zamagetsi zimakhala ndi magawo awiri: PWM rectifier ndi PWM inverter. Chowongolera cha PWM choyezedwa ndi gridi yamagetsi chidzapanga ma harmonics ambiri apamwamba akamagwira ntchito. Ngakhale kusefa kwa LC kumagwiritsidwa ntchito pagululi, kumayambitsabe kusokoneza kwa ma radiation ku gridi ndi zida zozungulira; magetsi aposachedwa a PWM alibe kusinthasintha kwapang'onopang'ono kumbali ya gridi, ndipo Pogwiritsa ntchito kusefa kwamitundu yambiri ya LC ndi kudzipatula kwa thiransifoma, mayesowa amatsimikizira kuti kusokoneza kwa ma radiation pagululi ndikochepa kwambiri, komanso kumagonjetsa mphamvu ya kunja kwa dziko pa electromagnetic yolimbikitsa magetsi.

5. Kukhazikika kwa zida: mphamvu yaposachedwa ya PWM yosinthira ma frequency, mbali yokonzanso imatengera njira yosalamulirika yosinthira kusintha kwachilengedwe, palibe dera lowongolera zovuta lomwe limafunikira, ndipo dera lozungulira ndi losavuta. Kuonjezera apo, chifukwa chogwiritsa ntchito maulendo angapo otetezera, kuphatikizapo kudziwika kwa mzere wolowera, DC capacitor braking unit , kutentha kwa madzi, kuthamanga kwa madzi, etc., makamaka chitetezo chambiri cha IGBT, chimapangitsa kuti dongosololi likhale lodalirika, komanso chikhalidwe chake chapamwamba, kukhwima ndi kukhazikika zikuwonekera kwambiri.

The electromagnetic stirrer yopangidwa ndi Huate ili ndi makasitomala oposa 200 apakhomo, ndipo yatumizidwa kumayiko oposa khumi ndi zigawo monga Brazil, Thailand ndi India, ndipo wakhala akuyamikiridwa kwambiri ndi makasitomala.

Shandong Huate Magnetoelectric Technology Co., Ltd. idakhazikitsidwa mu 1993 (katundu wazinthu: 831387). Kampaniyo ndi katswiri wodzipangira yekha, wotsogola pamlingo wadziko lonse, wapadera, komanso wabizinesi watsopano wa "chimphona chaching'ono", bizinesi yopanga zinthu zapadziko lonse lapansi, komanso bizinesi yaukadaulo yapadziko lonse lapansi. Ndi ntchito kiyi zapamwamba zamakono, ndi dziko nzeru katundu chionetsero malonda, ogwira ntchito kutsogolera mu Linqu magnetoelectric zida khalidwe mafakitale m'munsi mwa National Torch Program, wapampando wagawo la National Magnetoelectric ndi Low Kutentha Superconducting Application Technology Innovation Strategic Alliance, ndi Wachiwiri kwa Wapampando wa China Heavy Machinery Viwanda Association. . Pali malo opangira kafukufuku wasayansi wapadziko lonse lapansi, malo ogwirira ntchito aukadaulo, ma labotale ofunikira am'chigawo aukadaulo waukadaulo wamagetsi ndi zida, komanso malo am'chigawo chaukadaulo waukadaulo wamagetsi ndi zamagetsi ndi nsanja zina za R&D. Kuphimba malo okwana masikweya mita 270,000, ili ndi katundu wopitilira yuan 600 miliyoni ndi antchito opitilira 800. Ndi imodzi mwazinthu zazikulu kwambiri zopangira ndi kupanga zida zamaginito ku China. Okhazikika pakupanga zithunzi zachipatala za superconducting maginito, maginito osatha, ma elekitiromaginito ndi otsika kutentha kwa superconducting maginito olekanitsa, olekanitsa chitsulo, zida zonse za mgodi, maginito oyendetsa, ndi zina zotero, kuchuluka kwa ntchito kumakwirira migodi, malasha, mphamvu yamagetsi, zitsulo, zitsulo zopanda chitsulo ndi minda yachipatala, zogulitsidwa ku Australia, Germany, Brazil, India, South Africa ndi mayiko oposa 30.
