Ng'anjo yapakati pafupipafupi

Eddy current yopangidwa ndiIF ng'anjoalinso ena katundu wa wapakatikati pafupipafupi pakali pano, ndiye kuti, maelekitironi ufulu zitsulo palokha amayenda mu zitsulo thupi ndi kukana kupanga kutentha.Mtundu wa mlatho wokhala ndi magawo atatu wowongoleredwa bwino umagwiritsidwa ntchito kuwongolera njira yosinthira kuti ikhale yolunjika.Mwachitsanzo, silinda yachitsulo imayikidwa mu koyilo yolowera ndikusintha ma frequency apakatikati.Silinda yachitsulo sichimalumikizana mwachindunji ndi coil induction, ndipo kutentha kwa koyilo yopatsa mphamvu palokha ndikokwera kwambiri.Pansi, koma pamwamba pa silinda imatenthedwa mpaka kufiira komanso kusungunuka, ndipo kuthamanga kwa redness uku ndi kusungunuka kungapezeke kokha mwa kusintha mafupipafupi ndi mphamvu zamakono.Ngati silinda imayikidwa pakati pa koyilo, kutentha kuzungulira silinda kudzakhala kofanana, ndipo kutentha ndi kusungunuka kwa silinda sikudzatulutsa mpweya woipa kapena kuipitsa chilengedwe ndi kuwala kolimba.

Mfundo yogwirira ntchito:
Theng'anjo yapakati pafupipafupiamapangidwa makamaka ndi magetsi, koyilo yolowera ndi crucible yopangidwa ndi zida zokanira mu koyilo yolowera.The crucible imadzazidwa ndi zitsulo zolipiritsa, zomwe zimafanana ndi mphepo yachiwiri ya transformer.Pamene coil induction ilumikizidwa ndi magetsi a AC, mphamvu yamagetsi yosinthira imapangidwa mu koyilo yolowera, ndipo mizere yake yamphamvu yamaginito imadula chiwongolero chachitsulo mu crucible, ndipo mphamvu yopangira ma elekitirodi imapangidwa pamalipiro.Popeza kuti chiwongoladzanjacho chimapanga chipika chotsekedwa, kutsekemera kwachiwiri kumadziwika ndi kutembenuka kamodzi kokha ndipo kumatsekedwa.Choncho, mphamvu yowonongeka imapangidwira pamtengowo panthawi imodzimodzi, ndipo pamene mphamvu yowonongeka ikudutsa pamtengowo, ndalamazo zimatenthedwa kuti zilimbikitse kusungunuka kwake.

Ng'anjo yamagetsi yamagetsi yapakatikati imagwiritsa ntchito mphamvu yamagetsi yapakatikati kuti ikhazikitse maginito apakati pafupipafupi, kotero kuti eddy pano amapangidwa mkati mwazinthu za ferromagnetic ndikupanga kutentha, kuti akwaniritse cholinga chotenthetsera zinthuzo.Ng'anjo yamagetsi yapakati yapakati imatenga mphamvu yapakati ya 200-2500Hz yapakatikati kuti itenthetse, kusungunula ndi kusunga kutentha.Ng'anjo yamagetsi yapakati pafupipafupi imagwiritsidwa ntchito kwambiri kusungunula chitsulo cha kaboni, chitsulo cha aloyi, chitsulo chapadera, ndipo itha kugwiritsidwanso ntchito kusungunula ndi kutenthetsa zitsulo zopanda chitsulo monga mkuwa ndi aluminiyamu.Zida ndi zazing'ono kukula kwake ndi zopepuka kulemera.Kuwala, kuchita bwino kwambiri, kugwiritsa ntchito mphamvu zochepa, kusungunuka mwachangu ndi kutentha, kuwongolera mosavuta kutentha kwa ng'anjo, komanso kupanga bwino kwambiri.
