【Huate Magnetic Separation Encyclopedia】Kushandiswa kweElectromagnetic Stirrer muindasitiri yekugadzira zvinhu

Kukurunga kwemagetsi kunogona kumutsa aruminiyamu ichinyunguduka pasina kubata, kuita kuti makemikari akaenzana uye tembiricha yekunyunguduka ikwane, kuderedza kuumbwa kweoxide slag, kupfupisa nguva yekunyunguduka, kuvandudza kubereka, uye kuderedza zvakanyanya simba revashandi. Nekuda kwezvibatsiro zvakawanda zvekukurunga kwemagetsi, electromagnetic stirrer ikozvino yava mudziyo unokosha muindasitiri yekunyungudutsa nekugadzira aruminiyamu.

Kukurunga kwemagetsi kunogona kumutsa aruminiyamu ichinyunguduka pasina kubata, kuita kuti makemikari akaenzana uye tembiricha yekunyunguduka ikwane, kuderedza kuumbwa kweoxide slag, kupfupisa nguva yekunyunguduka, kuvandudza kubereka, uye kuderedza zvakanyanya simba revashandi. Nekuda kwezvibatsiro zvakawanda zvekukurunga kwemagetsi, electromagnetic stirrer ikozvino yava mudziyo unokosha muindasitiri yekunyungudutsa nekugadzira aruminiyamu.

Chinosanganisa magetsi nemagetsi chinowanzo gadzirwa nemagetsi anochinja-chinja uye inductor. Simba rinochinja simba re50/60Hz rinochinja magetsi kuita simba re3-phase low-frequency rine frequency ye0.5 ~ 5Hz. Mushure mekunge simba rabatanidzwa ne inductor coil, simba remagetsi rinofamba rinogadzirwa. Simba remagetsi rinofamba rinopinda muplate yesimbi isina tsvina pasi pechoto nechoto uye rinoita basa paaluminium yakanyungudutswa, kuitira kuti aluminum yakanyungudutswa ifambe nguva nenguva, kuitira kuti chinangwa chekukurunga chibudirire. Hukuru negwara resimba rekukurunga zvinogona kuchinjwa nekuchinja voltage, frequency uye phase yesimba remagetsi rinochinja-chinja.

Simba remazuva ano reAC, DC, AC rinopa simba renguva dzakasiyana-siyana rine kodzero dzepfungwa dzakazvimiririra dzakagadzirwa pamwe chete neHuateKambani neYunivhesiti yeNankai, Yunivhesiti yeShandong nemamwe makoreji nemayunivhesiti, ine kabhineti yekudzora uye kabhineti yemagetsi inoshanduka-shanduka kuti igadzire sisitimu yemagetsi inomhanyisa stirrer.

Tekinoroji yemazuva ano yePWM control inoputsa chimiro chakabatana che frequency converter kare. Zvichienderana nehunhu hwe load ye electromagnetic stirrer, dhizaini yakakosha ye software ne hardware inoitwa. Inogona kutakura mutoro mukuru we inductive pasina kuwedzera impedance matching pakati pemagetsi nemutoro, uye inogona kushanda pama frequency akaderera. Kushanda kwakagadzikana. PWM variable frequency power supply yazvino yakakodzera kushandiswa pama electromagnetic stirrers; zvichienzaniswa ne traditional variable frequency power supply, PWM variable frequency power supply yazvino yeHuateine hunhu hunotevera:

1. Simba: Simba remagetsi eAC-DC-AC variable frequency power supply yazvino inogona kusvika pa0.95, izvo zvinoenderana nemitemo yenyika yemasekete emagetsi ane zvikamu zvitatu (0.9-1). 0.95 kana kupfuura ndiyo yakanakisa. Kana simba remagetsi rakanyanya, voltage ichave yakanyanya. Zvichienzaniswa nemagetsi eAC-AC structure, kugona kwemuchina kwakaiswa kunogona kuderedzwa zvakanyanya.

2. Kurasikirwa kwekushanda kwakasimba: Rutivi rwekugadzirisa simba rePWM AC-DC-AC variable frequency power supply yazvino haidi circuit yekudzora yakaoma, michina pachayo ine kurasikirwa kushoma, uye kushanda kwekushandura kwakakwira kupfuura kwePWM circuit yechinyakare. Kana michina iri mumamiriro ekumira, simba remagetsi renguva inoshanduka rinofanira kuchinjana simba guru negrid yemagetsi kuitira kuchengetedza kugadzikana kwevoltage yebhasi reDC, nepo PWM yazvino isina kuchinjana simba negrid yemagetsi. Kana tichitarisa simba remagetsi rakaderera pane rechinyakare.

3. Kurasikirwa kwekushanda: Sezvo agitator iri mutoro weinductive, kwete mutoro wemhando yemota, hapana maitiro ekushandura kubva kusimba remakanika kuenda kusimba remagetsi, saka hapana mhinduro yesimba panguva yekushanda. Simba idzva rePWM rinoita kuti kuchinjana kwesimba re reactive ne inductive load kuburikidza ne intermediate large-capacity DC capacitor kuitwe, chete simba re energy buffer rinodiwa, uye hapana shanduko yesimba, Saka, simba rePWM razvino rine kurasikirwa kwakaderera kwekushanda kupfuura magetsi echinyakare anoshanduka-shanduka.

4. Mwaranzi yemagetsi: Nekuti simba rePWM rinoshanduka-shanduka rinoumbwa nemidziyo yemagetsi ine simba uye inogadziriswa ne high frequency carrier frequency, simba remazuva ano rinoshanduka-shanduka rine zvikamu zviviri: PWM rectifier uye PWM inverter. PWM rectifier inoyerwa ne power grid ichagadzira huwandu hwakawanda hwe high-order harmonics kana ichishanda. Kunyangwe LC filtering ichishandiswa kudivi re grid, ichiri kukonzera radiation interference kune grid nemidziyo yakapoteredza; PWM power supply yazvino haina high-frequency modulation kudivi re grid, uye Uchishandisa multi-stage LC filtering uye transformer isolation, bvunzo inoratidza kuti radiation interference kudivi re grid idiki kwazvo, uye inokundawo pesvedzero yenyika yekunze pane electromagnetic stirving power supply.

5. Kugadzikana kwemidziyo: simba rePWM variable frequency razvino, divi rekugadzirisa rinoshandisa nzira yekururamisa isingadzoreki yekuchinja kwechisikigo, hapana dunhu rekudzora rakaoma rinodiwa, uye dunhu riri nyore. Pamusoro pezvo, nekuda kwekushandiswa kwemasekete akawanda ekudzivirira, kusanganisira kuona mutsetse unouya, DC capacitor braking unit, tembiricha yemvura, kumanikidzwa kwemvura, nezvimwewo, kunyanya dziviriro yakawanda yeIGBT, inoita kuti sisitimu ishande zvakavimbika, uye hunhu hwayo hwepamusoro, kukura kwayo uye kugadzikana zviri pachena.

Chinogadzirwa neHuate chine vatengi vanopfuura mazana maviri vemuno, uye chakatumirwa kunyika dzinopfuura gumi nenzvimbo dzakadai seBrazil, Thailand neIndia, uye chakarumbidzwa zvikuru nevatengi.

Shandong Huate Magnetoelectric Technology Co., Ltd. yakavambwa muna 1993 (kodhi yemasheya: 831387). Kambani iyi inyanzvi yekugadzira zvinhu munyika, kambani yakasarudzika, yakakosha, uye itsva "diki hombe" padanho renyika, kambani itsva padanho renyika, uye kambani itsva padanho renyika. Ikambani yakakosha yetekinoroji yepamusoro, kambani yekuratidza pfuma yepfungwa yenyika, kambani inotungamira muLinqu magnetoelectric equipment characteristic industrial base yeNational Torch Program, sachigaro weNational Magnetoelectric and Low Temperature Superconducting Application Technology Innovation Strategic Alliance, uye mutevedzeri wesachigaro weChina Heavy Machinery Industry Association. Kune nzvimbo dzebasa dzekutsvaga scientific post-doctoral dzepamusoro-soro, nzvimbo dzebasa dzedzidzo dzakakwana, maprovince key laboratories e magnetic application technology and equipment, uye province magnetic and electrical engineering technology centers nedzimwe nzvimbo dzeR&D. Iine nzvimbo yese ye270,000 square metres, ine pfuma inosvika mamiriyoni mazana matanhatu eyuan nevashandi vanopfuura mazana masere. Ndiyo imwe yenzvimbo huru dzekugadzira nekugadzira michina yemagineti muChina. Iine hunyanzvi mukugadzira mifananidzo yemagineti inonzi superconducting magnetic resonance, magineti anogara aripo, magineti anoita superconducting magnetic separator ane electromagnetic ne low temperature, magineti anoita iron separator, magineti akazara emugodhi, magineti anoita stirrers, nezvimwewo, basa iri rinofukidza migodhi, marasha, simba remagetsi, simbi, simbi dzisina ferrous neminda yekurapa, inotengeswa kuAustralia, Germany, Brazil, India, South Africa nenyika dzinopfuura makumi matatu.
