Iyo yepakati frequency furenace chishandiso chemagetsi chinoshandura 50Hz AC simba kuita yepakati frequency (300Hz kusvika 100Hz) simba, yobva yashandura matatu-chikamu AC simba kuita DC simba, uyezve inoshandura iyo DC simba kuita inogadziriswa yepakati frequency frequency ikozvino, iyo. inoyerera nema capacitors uye induction coils.Gadzira yakakwira-density magineti emagetsi mitsara, cheka simbi zvinhu muinduction coil, shandisa musimboti wemagetsi induction kugadzira hombe eddy ikozvino yesimbi zvinhu, kupisa simbi zvinhu, uye kuinyungudutsa.
Iyo yepakati frequency induction furnace ndeye discrete system mutoro.Munguva yekushanda, maharmonic currents anounzwa mugedhi remagetsi, zvichikonzera pulse current voltage pane hunhu hunhu hwegidhi remagetsi, zvichikonzera kushanduka kwemagetsi mugidhi remagetsi, uye kukanganisa kunaka kwesimba rekupa magetsi uye kushanda kwekuchengetedza kwemidziyo. .Sezvo simba rekutengesa reiyo yepakati frequency furefu rave frequency yepakati kuburikidza nekugadzirisa frequency converter, gidhi remagetsi richagadzira huwandu hukuru hwekukuvadza kwepamusoro-soro harmoniki panguva yekushanda, inova imwe yeakanyanya kurongeka eHarmonic masosi mumhepo. simba grid mutoro.
Maitiro mashanu epakati frequency furnace
1. Chengetedza mari
Kukurumidza kupisa, kubereka kwakanyanya, kushomeka kwemhepo oxidation carburization, kuchengetedza mbishi nemitengo, uye kurebesa hupenyu hwesevhisi yezvishandiso zvinokuvadza.
Nekuti musimboti weyepakati frequency induction furnace ndeye electromagnetic, kupisa kunogadzirwa nepakati frequency induction furnace inogadzirwa nesimbi pachayo.Vashandiwo zvavo vanogona kuita basa rinoenderera mberi rekugadzira mukati memaminitsi gumi mushure mekushandisa yepakati frequency induction choto, pasina kudiwa kwekugadzira choto.Vashandi vakatanga kupfutidza nokuisa chisimbiso pachine nguva mberi.Nekuti iyi nzira yekudziya inopisa nekukasira uye ine oxidation shoma, iyo oxidation ablation yepakati frequency kupisa simbi castings ingori 0.5%, oxidation ablation yekudziya gasi yevira i2%, uye mbishi marasha emarasha inodarika 3%.Iyo yepakati frequency yekudziya maitiro inochengetedza Raw zvinhu, zvichienzaniswa nembishi marasha emarasha, tani imwe yesimbi yekukandira inochengetedza 20-50KG mahwendefa esimbi asina tsvina.Huwandu hwayo hwekushandisa mbishi hunogona kusvika 95%.Nekuti kupisa kwakafanana uye mutsauko wetembiricha pakati pepakati pepamusoro idiki, hupenyu hwesevhisi yekufa kwefogi hunowedzerwa zvakanyanya panguva yekugadzira.Iyo yekugadzira roughness yakaderera pane 50um, uye tekinoroji yekugadzira inochengetedza simba.Iyo yepakati frequency yekudziya inogona kuchengetedza simba ne31.5% -54.3% kana ichienzaniswa nekudziya kwemafuta, uye gasi kudziyisa Energy kuchengetedza 5% -40%.Hunhu hwekudziya hwakanaka, chiyero chezvikara chinogona kuderedzwa ne1.5%, chiyero chekubuda chinogona kuwedzerwa ne10% -30%, uye hupenyu hwesevhisi yeabrasive tool inogona kuwedzerwa ne10% -15%.
2. Mapoinzi ekuchengetedza kwezvakatipoteredza
Yakanakisa hofisi nharaunda, inovandudza nharaunda yehofisi yevashandi uye yemakambani brand image, zero kusvibiswa, kuchengetedza simba.
Kuenzaniswa nezvitofu zvemarasha, induction heat furnaces haichakwanise kuputa nezvitofu zvemarasha pasi pekupisa kwakanyanya, izvo zvinogona kusangana nemirairo yeEnvironmental Protection Agency.Pamusoro pezvo, inogona kuumba mufananidzo wekunze wekambani uye kugadzira indasitiri yekusimudzira maitiro eindasitiri yekugadzira.Induction heat ndiko kudziyisa kwemagetsi echoto simba kubva mukamuri tembiricha kusvika 100 ° C, simba rekushandisa riri pasi pe30 ° C, uye kudyiwa kwefogi kuri pasi pe30 ° C.Partition nzira yekugadzira kushandiswa
3. Kupisa muchero
Uniform kupisa, diki tembiricha musiyano pakati pepakati nepamusoro, yakakwirira tembiricha kutonga kurongeka
Induction heat inoburitsa kupisa musimbi pachayo, saka kudziyisa kwakafanana uye musiyano wetembiricha pakati pepakati nepamusoro idiki.Iko kushandiswa kwetembiricha yekudzora system inogona kunyatso kudzora tembiricha, kunatsiridza mhando yechigadzirwa uye chiyero chekupasa.
4. Rate
Iyo yepakati frequency choto inopisa nekukurumidza, iyo yekunyunguduka simbi inoshandisa magetsi emagetsi asingadariki madhigirii 500, uye kunyunguduka kwacho kunowedzera uye nekukurumidza.
5. Kuchengetedza kushanda
Iyo kure yekutarisa sisitimu yepakati frequency electric furnace inosarudzwa, iyo yakakodzera kune indasitiri yekugadzira nharaunda.Yakasimba kupesana-kupindira kugona uye yakakwirira kuchengetedza chinhu.Iko hakuna waya yakabatana pakati pechishandiso chekushandisa uye chigadziriso chinodzorwa, ndiko kuti, kure kure.Pakuita kwese kwakaoma, dzvanya makiyi eremote control uri kure.Mushure mekugamuchira mirairo, yepakati frequency yemagetsi furefu inogona kupedzisa inoenderana mashandiro nhanho nhanho zvinoenderana nemaitiro akanaka.Nemhaka yokuti choto chemagetsi chigadziko chemagetsi chepamusoro-soro, haisi kungochengeteka chete, asiwo inogona kudzivisa kukanganisa kwechoto chemagetsi nekuda kwekutya kunokonzerwa nezvikanganiso zvekushanda.
Nei iyo yepakati frequency choto ichigadzira harmonics
Harmonics ichaisa mungozi zvakanyanya kushanda kwakachengeteka kwegedhi remagetsi.Semuyenzaniso, harmonic yazvino inokonzeresa yakawedzera-frequency vortex iron kurasikirwa mutransformer, izvo zvichaita kuti transformer iwedzere kupisa, kuderedza kubuda kwevhoriyamu yetransformer, kuwedzera ruzha rwetransformer, uye kukanganisa zvakanyanya hupenyu hwesevhisi. .Iyo inonamatira mhedzisiro ye harmonic currents inoderedza inogara ichiyambuka-chikamu che conductor uye inowedzera kurasikirwa kwemutsara.Harmonic voltage inokanganisa kushanda kwakajairwa kwezvimwe midziyo yemagetsi pane grid, zvichikonzera zvikanganiso zvekushanda mu otomatiki kudzora michina uye isina kurongeka kuyerwa kwechokwadi.Harmonic voltage uye yazvino inokanganisa kushanda kwakajairwa kwemidziyo yekutaurirana;kuwedzeredza kwechinguvana uye kuwedzeredza kwechinguvana kunokonzerwa neharmonics kukuvadza iyo insulation layer yemuchina nemidziyo, zvichikonzera matatu-chikamu chepfupi-yedunhu kukanganisa uye kukuvadza kune transformer;harmonic voltage uye Huwandu hwemazuva ano huchakonzera chikamu chakatevedzana resonance uye parallel resonance mugedhi remagetsi eruzhinji, zvichikonzera tsaona huru.Mukuita kwese kwemagetsi inverter magetsi, yekutanga DC yakagadzikana magetsi is square wave switching power supply, iyo yakaenzana nekuunganidzwa kwemasaisai ane akawanda akakwira-kurongeka pulse currents.Kunyangwe iyo post-stage yedunhu inoda sefa, iyo harmonics haigone kusefa kunze, iyo ndiyo inokonzera harmonics.
Harmonic simba repakati frequency furnace
Iro simba rekubuda reyepakati frequency induction vira rakasiyana, uye maharmonics akasiyana zvakare akasiyana:
1. Simba rechisikiro chepamusoro-simba repakati frequency furnace iri pakati pe0.8 ne0.85, reactive simba rinodiwa rakakura, uye harmonic content yakakwirira.
2. Simba rechisikigo revhu-simba repakati frequency furnace riri pakati pe0.88 ne0.92, uye reactive simba rinodiwa idiki, asi harmonic content yakanyanya.
3. The net side harmonics yepakati frequency furnace inonyanya 5th, 7th uye 11th.
Harmonic control nzira yepakati frequency furnace
Single-tuned mafirita e5, 7, 11 uye 13 nguva akagadzirwa.Pamberi pemuripo wefirita, iyo simba chinhu chemutengi wepakati frequency induction furnace melting link ndeye 0.91.Mushure mesefa yekubhadhara michina yaiswa mukushanda, iyo yakanyanya muripo ndeye 0.98 capacitive.Mushure mekunge sefa yemuripo wemidziyo yaiswa mukushanda, iyo yakazara yekushanda voltage distortion rate (yakazara harmonic kukanganisa kukosha) i2.02%.Zvinoenderana nemagetsi emhando yepamusoro GB/GB/T 14549-1993, iyo inoshanda voltage harmonic (10KV) kukosha yakaderera pane 4.0%.Mushure mekuita mafirita pa5th, 7th, 11th uye 13th harmonic currents, iyo filter rate inenge 82∽84%, iyo inodarika kukosha kwekutonga kweiyo kambani indasitiri chiyero.Muripo wesefa mhedzisiro yakanaka.
