Kutentha kwa induction ndi njira yatsopano, ndipo kugwiritsa ntchito kwake kumachitika makamaka chifukwa cha mawonekedwe ake apadera.

Pamene mphamvu yosinthasintha mofulumira ikuyenda kudzera mu chitsulo chogwirira ntchito, imapanga zotsatira za khungu, zomwe zimayika mphamvu yamagetsi pamwamba pa chitsulocho, ndikupanga gwero la kutentha losankha kwambiri pamwamba pa chitsulocho. Faraday adapeza ubwino uwu wa zotsatira za khungu ndipo adapeza chodabwitsa cha induction yamagetsi. Iye ndiyenso anayambitsa induction heating. Induction heating sikufuna gwero la kutentha lakunja, koma imagwiritsa ntchito workpiece yotenthedwa yokha ngati gwero la kutentha, ndipo njira iyi sikutanthauza kuti workpiece igwirizane ndi gwero la mphamvu, lomwe ndi induction coil. Zina mwazinthu zimaphatikizapo kuthekera kosankha kuya kosiyanasiyana kwa kutentha kutengera mafupipafupi, kutentha kolondola kwapafupi kutengera kapangidwe ka coil coupling, ndi mphamvu yayikulu, kapena kuchuluka kwa mphamvu yayikulu.

 

Njira yochizira kutentha yoyenera kutenthetsera mpweya iyenera kugwiritsa ntchito bwino mawonekedwe awa ndikupanga chipangizo chathunthu potsatira njira zotsatirazi.

 

Choyamba, zofunikira pa ndondomekoyi ziyenera kugwirizana ndi makhalidwe oyambira a kutentha kwa induction. Mutu uno ufotokoza zotsatira za maginito mu workpiece, kugawa kwa mphamvu yotuluka, ndi mphamvu yoyamwa. Malinga ndi zotsatira za kutentha ndi kutentha komwe kumapangidwa ndi mphamvu yoyambitsidwa, komanso kugawa kutentha pama frequency osiyanasiyana, mawonekedwe osiyanasiyana achitsulo ndi workpiece, ogwiritsa ntchito ndi opanga angasankhe kutaya malinga ndi zofunikira zaukadaulo.

 

Chachiwiri, mtundu weniweni wa kutentha kwa induction uyenera kutsimikiziridwa malinga ndi ngati ukukwaniritsa zofunikira zaukadaulo, komanso uyenera kumvetsetsa bwino momwe ntchito ndi chitukuko chake zimagwiritsidwira ntchito, komanso momwe kutentha kwa induction kumagwiritsidwira ntchito.

 

Chachitatu, pambuyo poti kuyenerera ndi kugwiritsa ntchito bwino kwa kutentha kwa induction kwatsimikizika, sensa ndi makina opangira magetsi zitha kupangidwa.

Mavuto ambiri pa kutentha kwa induction amafanana kwambiri ndi chidziwitso choyambira cha uinjiniya, ndipo nthawi zambiri amachokera ku zomwe zachitika. Zinganenedwenso kuti n'zosatheka kupanga chotenthetsera cha induction kapena makina popanda kumvetsetsa bwino mawonekedwe a sensa, kuchuluka kwa magetsi, komanso momwe chitsulo chotenthetsera chimagwirira ntchito.

 

Zotsatira za kutentha kwa induction, motsogozedwa ndi mphamvu ya maginito yosaoneka, ndizofanana ndi kuzimitsa moto.

Mwachitsanzo, ma frequency apamwamba opangidwa ndi jenereta ya ma frequency apamwamba (oposa 200000 Hz) nthawi zambiri amatha kupanga gwero la kutentha lamphamvu, lachangu komanso lokhazikika, lomwe limafanana ndi ntchito ya lawi laling'ono komanso lolimba la gasi lotentha kwambiri. M'malo mwake, mphamvu ya kutentha ya ma frequency apakati (1000 Hz ndi 10000 Hz) imafalikira kwambiri komanso pang'onopang'ono, ndipo kutentha kumalowa mozama, mofanana ndi lawi lalikulu komanso lotseguka la gasi.
