Induction Heating Basics

Induction Kutya kunoitika mune chinhu chinoitiswa nemagetsi (kwete sengeti yemagineti) kana chinhu chacho chaiswa mune inosarudzika yemagineti. Kupinza kupisa kunokonzerwa neiyo hysteresis uye eddy-ikozvino kurasikirwa.

Induction kupisa basicsInduction Kutya ndiyo nzira yekudziya yemagetsi inoitisa chinhu (kazhinji simbi) nemagetsi emagetsi, kupisa kuburitswa mune chinhu ne eddy mafungu. Iyo induction heater ine electromagnet uye yemagetsi oscillator iyo inopfuura yakakwirira-frequency alternating ikozvino (AC) kuburikidza negetsi. Iyo inokurumidza kuchinjanisa magineti inopinda mukati mechinhu, ichiburitsa magetsi emagetsi mukati mekondakita, anonzi eddy maawa. Iwo eddy mafungu anoyerera kuburikidza nekudzivirira kwechinhu kupisa kwacho naJoule kudziya. Mu ferromagnetic (uye ferrimagnetic) zvinhu simbi, kupisa kunogona zvakare kugadzirwa nemagineti hysteresis kurasikirwa. Iyo frequency yezvino inoshandiswa zvinotsamira pahukuru hwechinhu, rudzi rwezvinhu, kusanganisa (pakati peiyo coil yebasa uye chinhu chinofanira kupiswa) uye kudzika kwekupinda

Hysteresis kurasikirwa kunowanzoitika mune magineteri zvakadai sesimbi, nickel, uye vashoma zvikuru. Kurasikirwa kweHysteresis inotaura kuti izvi zvinokonzerwa nekukanganiswa pakati pemamolekoro apo zvinhu zvakagadzirwa magnetized kutanga mune imwe nzira, uyezve mune imwe. Mamolekoro angave anoonekwa semashizha maduku anotenderera nechinongedzo chimwe nechimwe chekutungamirirwa kwemagnetic field. Shandisa (simba) rinodiwa kuti uvashandure. Simba rinoshandura rikava kupisa. Mutengo wekushandiswa kwesimba (simba) unowedzera nehuwandu huwandu hwekuchinja (huwandu).

Eddy-ikozvino kurasikirwa kunowanikwa mune chero chekuita zvinhu mune imwe nyika inoita magnetic field. Izvi zvinokonzera kutungamira, kunyange kana zvinhu zvacho zvisina chero magnetic zvinhu zvinowanzobatanidzwa nesimbi nesimbi. Mienzaniso imhangura, ndarira, aluminium, zirconium, simbi isina magnetic, uye uranium. Mavhiri eddy ndiwo magetsi emagetsi anotsoropodzwa nekushandura gadziriro mumashoko. Sezvo zita ravo rinoreva, vanoita sevari kufamba-famba vachitenderera mumasikirwo mukati mehutu hwakasimba. Eddy-ikozvino kurasikirwa kunonyanya kukosha kupfuura hysteresis kurasikirwa mukutengesa kupinza. Cherechedza kuti kupisa kwekugadzirisa zvinoshandiswa kune zvisingabatsiri, uko kusina hysteresis kurasika kunoitika.

Induction kupisa dzidzisoNekudziya kwesimbi yekuomesa, kuumba, kusungunuka, kana zvimwe zvinangwa zvinoda kutonhora pamusoro pekushisa kweCurie, hatigoni kuvimba ne hysteresis. Sirasi inoshaya magnetic yayo pamusoro pekushisa uku. Apo simbi inopisa pasi peCurie point, mupiro we hysteresis inowanzoita shoma zvokuti inogona kuregererwa. Nokuda kwezvinangwa zvose, I2R yemvura yakasviba ndiyo nzira chete iyo magetsi emagetsi inogona kushandurwa kuva kupisa kwechinangwa chokupisa.

Zvinhu zviviri zvakakosha zvekutsvaira kwekugadzirira kuitika:

  • A kuchinja magnetic field
  • Anogadzirwa nemagetsi anoiswa mumagnetic field
