【Huate Magnetic Separation Encyclopedia】Kushandiswa kweElectromagnetic Stirrer muIndasitiri yekukanda

Electromagnetic inomutsa inogona kunyatso mutsa aluminium kunyungudika pasina kubata, homogenize chimiro chemakemikari uye tembiricha yekunyunguduka, kuderedza kuumbwa kweoxide slag, kupfupisa nguva yekunyungudika, kugadzirisa chibereko, uye kuderedza zvakanyanya kuwanda kwevashandi. Nekuda kwemabhenefiti akawanda emagetsi ekukurudzira, electromagnetic stirrer yave chinhu chakakosha muindasitiri yekunyunguduka uye yekukanda.

Electromagnetic inomutsa inogona kunyatso mutsa aluminium kunyungudika pasina kubata, homogenize chimiro chemakemikari uye tembiricha yekunyunguduka, kuderedza kuumbwa kweoxide slag, kupfupisa nguva yekunyungudika, kugadzirisa chibereko, uye kuderedza zvakanyanya kuwanda kwevashandi. Nekuda kwemabhenefiti akawanda emagetsi ekukurudzira, electromagnetic stirrer yave chinhu chakakosha muindasitiri yekunyunguduka uye yekukanda.

Iyo electromagnetic stirrer inonyanya kuumbwa neinosiyana frequency magetsi magetsi uye inductor. Iyo inoshanduka frequency magetsi inoshandura iyo 50 / 60Hz magetsi frequency alternating current kuita 3-phase low-frequency power supply ine frequency ye0.5 ~ 5Hz. Mushure mekunge magetsi abatanidzwa kune inductor coil, inofamba wave magineti inogadzirwa. Inofamba magineti inopinda mundiro yesimbi isina simbi iri pazasi pechoto uye muchinjiro wechoto uye inoshanda paaluminium yakanyungudutswa, kuitira kuti aruminiyamu yakanyungudutswa ifambe nguva dzose, kuitira kuti izadzise chinangwa chekuzunguza. Hukuru uye kutungamira kwesimba rinokurudzira rinogona kushandurwa nekushandura voltage, frequency uye chikamu cheiyo inochinja frequency magetsi.

Iyo yazvino AC, DC, AC inosiyana frequency magetsi ekupa ine yakazvimirira yehungwaru kodzero yepfuma yakabatana yakagadzirwa naHuate.Kambani neNankai University, Shandong University uye mamwe makoreji nemayunivhesiti, inoumbwa nekabati yekudzora uye inosiyana frequency magetsi emagetsi kabati kuti igadzire iyo electromagnetic stirrer drive system.

Iyo yazvino PWM yekudzora tekinoroji inotyora iyo yakabatana chimiro cheiyo frequency converter munguva yakapfuura. Zvinoenderana nehunhu hwekuremerwa kweiyo electromagnetic stirrer, iyo yakakosha dhizaini yesoftware uye hardware inoitwa. Iyo inogona kutakura yakakura inductive mutoro pasina kuwedzera impedance inofananidzwa pakati pemagetsi uye mutoro, uye inogona kushanda pane yakaderera frequencies. Basa rakagadzikana. Iyo ichangoburwa PWM inosiyanisa ma frequency emagetsi anonyanya kukodzera kunyorera pane electromagnetic stirrers; kana ichienzaniswa neyechinyakare dhizaini yemagetsi magetsi, yazvino PWM inochinja frequency magetsi ekupa Huateine zvinotevera maitiro:

1.Power factor: Simba remagetsi ekupedzisira AC-DC-AC kushanduka kwemagetsi emagetsi anogona kusvika kupfuura 0.95, iyo inonyatsoenderana nemitemo yenyika yezvikamu zvitatu zvemagetsi emagetsi (0.9-1). 0.95 kana zvakadaro ndiyo yakanyanya kunaka. Kana simba racho rakanyanyisa, voltage inenge yakanyanyisa. Kuenzaniswa neiyo AC-AC dhizaini yemagetsi, iyo yakaiswa yechigadzirwa inogona kuderedzwa zvakanyanya.

2.Kurasikirwa kwekushanda kwakasimba: Iro rectifier divi rekupedzisira PWM AC-DC-AC chinja-chinja frequency magetsi haadi yakaoma dhizaini yekudzora, iyo midziyo pachayo ine kurasikirwa kushoma, uye kushandura kunoshanda kwakakwira kupfuura iyo yechinyakare PWM dunhu. . Kana iyo michina iri munzvimbo yekumira, iyo yechinyakare inochinja frequency magetsi inoda kuchinjanisa simba rakakura negetsi remagetsi kuitira kuchengetedza kugadzikana kweiyo DC bhazi voltage, nepo ichangoburwa PWM inochinja frequency magetsi isina kana simba rekuchinjana nayo. iyo grid yemagetsi. Panyaya yakaderera pane zvechinyakare magetsi.

3. Kurasikirwa kwekushanda: Sezvo agitator iri inductive load, kwete motokari-mhando mutoro, hapana nzira yekushandura kubva kumagetsi emagetsi kune simba remagetsi, saka pane inenge isina simba remhinduro panguva yekushanda. Iyo nyowani PWM yemagetsi magetsi inoona reactive simba rekuchinjana neiyo inductive mutoro kuburikidza nepakati-hombe-simba DC capacitor, chete simba buffer inodiwa, uye hapana shanduko yemagetsi, Naizvozvo, ichangoburwa PWM magetsi ine yakaderera kushanda kurasikirwa pane yechinyakare. siyana frequency magetsi magetsi.

4. Electromagnetic radiation: Nekuti PWM inosiyana frequency magetsi emagetsi inoumbwa nemagetsi emagetsi emagetsi uye yakagadziridzwa nepamusoro frequency carrier frequency, yechinyakare inosiyana frequency magetsi magetsi ine zvikamu zviviri: PWM rectifier uye PWM inverter. Iyo PWM rectifier yakayerwa negiredhi yemagetsi inoburitsa huwandu hukuru hwepamusoro-kurongeka maharmoni kana ichinge ichishanda. Kunyangwe LC kusefa ichishandiswa padivi regidhi, ichiri kukonzera kukanganiswa kwemwaranzi kune grid uye nemidziyo yakatenderedza; iyo ichangoburwa PWM magetsi haina yakakwira-frequency modulation padivi regidhi, uye Uchishandisa akawanda-nhanho LC kusefa uye kuparadzaniswa kwekushandura, bvunzo inoratidza kuti kupindira kwemwaranzi padivi regidhi idiki kwazvo, uye zvakare inokunda simba reiyo. kunze kwenyika pamagetsi emagetsi anokurudzira magetsi.

5. Equipment kugadzikana: ichangoburwa PWM inochinja frequency simba rekupa, iyo rectifier side inotora isingadzoreki kugadzirisa nzira yekuchinja kwechisikigo, hapana yakaoma control circuit inodiwa, uye dunhu riri nyore. Uye zvakare, nekuda kwekushandiswa kwemaseketi ekudzivirira akawanda, anosanganisira anouya mutsara kuona, DC capacitor braking unit, tembiricha yemvura, kudzvanywa kwemvura, nezvimwewo, kunyanya kudzivirira kwakawanda kweIGBT, kunoita kuti sisitimu ishande yakavimbika, uye hunhu hwayo hwepamberi, kukura uye kugadzikana zviri pachena.

Iyo electromagnetic stirrer inogadzirwa naHuate ine vatengi vepamba vanodarika mazana maviri, uye yakatengeswa kunyika dzinopfuura gumi nematunhu akaita seBrazil, Thailand neIndia, uye yakarumbidzwa zvikuru nevatengi.

Shandong Huate Magnetoelectric Technology Co., Ltd. yakavambwa muna 1993 (stock code: 831387). Kambani iyi inyanzvi yenyika yekugadzira yega yega shasha, nyika-nhanho nyanzvi, yakakosha, uye nyowani kiyi "diki hofori" bhizinesi, bhizinesi repadanho renyika, uye bhizinesi renyika. Iri ibhizimusi repamusoro-soro, bhizinesi rekuratidzira pfuma yenyika, bhizinesi rinotungamira muLinqu magnetoelectric zvishandiso zvine hunhu hweindasitiri yeNational Torch Chirongwa, sachigaro chikamu cheNational Magnetoelectric uye Low Temperature Superconducting Application Technology Innovation Strategic Alliance, uye mutevedzeri wasachigaro chikwata cheChina Heavy Machinery Industry Association. . Kune nyika-level post-doctoral sainzi research workstations, yakazara academician workstations, provincial kiyi marabhoritari yemagnetic application tekinoroji nemidziyo, uye purovhinzi magineti nemagetsi engineering tekinoroji nzvimbo uye mamwe mapuratifomu eR&D. Kuvhara nzvimbo yese ye270,000 square metres, ine midziyo yakazara inodarika 600 miriyoni yuan uye vanopfuura mazana masere vashandi. Ndiyo imwe yehukuru hunyanzvi hwekugadzira uye mabhesi ekugadzira magineti yekushandisa muChina. Inyanzvi mukugadzirwa kwezvekurapa superconducting magineti resonance mifananidzo, magineti echigarire, emagetsi uye yakaderera tembiricha superconducting magineti separators, iron separators, yakazara seti yemidziyo yemugodhi, magineti inosimudzira, nezvimwe, iyo sevhisi inovhara migodhi, marasha, simba remagetsi, simbi, simbi dzisina-ferrous neminda yekurapa, inotengeswa kuAustralia, Germany, Brazil, India, South Africa uye nyika dzinopfuura makumi matatu.
