Kuzimitsa kwa induction ndi njira yozimitsira yomwe imagwiritsa ntchito kutentha komwe kumapangidwa ndi kulowetsedwa kwapano komwe kumadutsa popanga kuti kutenthetsera pamwamba ndi gawo lapafupi la forging mpaka kutentha kozimitsa, ndikutsatiridwa ndi kuzizira kofulumira. Panthawi yozimitsa, kuyikako kumayikidwa mu sensa yamkuwa ndikulumikizidwa ndi njira yosinthira pafupipafupi kuti ipangitse kutulutsa kwamagetsi, komwe kumapangitsa kuti pakhale kupangitsidwa kwaposachedwa pamwamba pakupanga komwe kuli kosiyana ndi komwe kulipo mu coil induction. Lupu lotsekeka lopangidwa ndi mphamvuyi yomwe imapangidwira pamwamba pake imatchedwa eddy current. Pansi pa mphamvu ya eddy current ndi kukana kwa kudzipangira yokha, mphamvu yamagetsi imasandulika kukhala mphamvu yotentha pamwamba pa kupangika, kuchititsa kuti pamwamba pakhale kutentha kwachangu mpaka kusefukira kwa quenching, pambuyo pake kupangika kumakhala nthawi yomweyo komanso mofulumira. utakhazikika kuti ukwaniritse cholinga cha kuzimitsa pamwamba.
Chifukwa chomwe mafunde a eddy amatha kutenthetsera pamtunda zimatsimikiziridwa ndi mawonekedwe a kugawa kwapano mu kondakitala. Makhalidwewa ndi awa:
- Khungu Zotsatira:
Pamene magetsi achindunji (DC) akudutsa pa kondakitala, kachulukidwe kameneka kamakhala kofanana ndi gawo lonse la kondakitala. Komabe, pamene alternating current (AC) ikudutsa, kugawa kwapano pagawo la kondakitala kumakhala kosagwirizana. Kachulukidwe kamakono kamakhala kokwera pamwamba pa kondakitala ndi kutsika pakati, ndi kachulukidwe kameneka kakuchepa kwambiri kuchokera pamwamba mpaka pakati. Chodabwitsa ichi chimadziwika kuti khungu la AC. Kuchuluka kwafupipafupi kwa AC, kumawonekera kwambiri khungu. Kuzimitsa kutentha kwa induction kumagwiritsa ntchito izi kuti zikwaniritse zomwe mukufuna.
- Zapafupi:
Pamene ma conductor awiri oyandikana amadutsa pakalipano, ngati njira yomwe ili pano ili yofanana, mphamvu yobwerera kumbuyo kumbali yoyandikana ndi ma kondakitala awiriwo ndi yaikulu kwambiri chifukwa cha kuyanjana kwa maginito omwe amapangidwa ndi maginito, ndipo zamakono zimayendetsedwa ku. mbali yakunja ya kondakitala. M'malo mwake, pamene njira yamakono ikutsutsana, zamakono zimayendetsedwa kumbali yoyandikana ndi oyendetsa awiriwo, ndiko kuti, kutuluka kwamkati, chodabwitsa ichi chimatchedwa zotsatira zapafupi.
Pakuwotcha kwa induction, pompopompo yomwe imapangidwira pakupanga nthawi zonse imakhala yosiyana ndi yomwe ilipo mu mphete yolowetsa, kotero kuti yapano pa mphete yolowera imayang'ana mkati mwake, ndipo yapano pamagetsi otentha omwe amapezeka mu mphete yolowera. imakhazikika pamtunda, yomwe ili chifukwa cha kuyandikira kwapafupi ndi zotsatira za khungu.
Pansi pa zochitika zapafupi, kugawa kwaposachedwa komwe kumapangidwira pamwamba pazitsulo kumakhala kofanana kokha pamene kusiyana pakati pa coil induction ndi forging kuli kofanana. Chifukwa chake, kupangirako kuyenera kuzunguliridwa mosalekeza pakuwotcha kwa induction kuti athetse kapena kuchepetsa kutentha komwe kumachitika chifukwa cha kusiyana kofanana, kuti mupeze yunifolomu yotentha yotentha.
Kuonjezera apo, chifukwa cha kuyandikira kwapafupi, mawonekedwe a malo otentha pazitsulo nthawi zonse amakhala ofanana ndi mawonekedwe a coil induction. Chifukwa chake, popanga koyilo yolowera, ndikofunikira kupanga mawonekedwe ake ofanana ndi mawonekedwe a malo otentha a forging, kuti akwaniritse kutentha kwabwino.
- Kayendedwe Kayendedwe:
Pamene alternating panopa akudutsa mphete woboola pakati kapena helical kondakitala, chifukwa cha zochita za alternating maginito, kachulukidwe panopa pa kunja kwa kondakitala amachepetsa chifukwa cha kuwonjezeka kudzikonda inductive kumbuyo electromotive mphamvu, pamene mkati padziko lapansi. mpheteyo imakhala yolimba kwambiri. Chodabwitsa ichi chimadziwika kuti circulation effect.
Kuzungulira kungathe kusintha kutentha kwachangu ndi liwiro pamene Kutentha pamwamba pa chidutswa chopukutira. Komabe, ndizosathandiza pakuwotcha mabowo amkati, chifukwa kufalikira kumapangitsa kuti pakali pano mu inductor achoke pamwamba pa chidutswa chopangidwa, zomwe zimapangitsa kuti kuchepetsa kutentha kwachangu komanso kuthamanga kwapang'onopang'ono. Chifukwa chake, ndikofunikira kuyika zida zamaginito zokhala ndi permeability kwambiri pa inductor kuti ziwonjezeke bwino.
Kuchuluka kwa chiŵerengero cha kutalika kwa axial kwa inductor mpaka m'mimba mwake mwa mphete, kumawoneka bwino kwambiri. Choncho, mtanda gawo la inductor bwino anapanga amakona anayi; mawonekedwe amakona anayi ndi abwino kuposa masikweya, ndipo mawonekedwe ozungulira ndi oyipa kwambiri ndipo ayenera kupewedwa momwe angathere.
- The sharp Angle effect:
Pamene mbali zotuluka ndi ngodya zakuthwa, m'mphepete m'mphepete ndi yaying'ono yopindika utali wozungulira ndi kutenthedwa mu kachipangizo, ngakhale kusiyana pakati kachipangizo ndi forging ndi wofanana, maginito mzere kachulukidwe mu ngodya lakuthwa ndi mbali zotuluka za forging ndi lalikulu. , kachulukidwe kameneka kameneka kamakhala kokulirapo, kutentha kwachangu kumathamanga, ndipo kutentha kumakhala kokhazikika, zomwe zidzachititsa kuti zigawozi ziwotche komanso ziwotche. Chodabwitsa ichi chimatchedwa sharp Angle effect.
Pofuna kupewa kuthwa kwa Angle effect, popanga sensa, kusiyana pakati pa sensa ndi mbali yakuthwa kapena mbali ya convex ya kupangika kuyenera kukulitsidwa moyenera kuti muchepetse kuchuluka kwa maginito amphamvu pamenepo, kuti liwiro la kutentha ndi liwiro la kutenthetsa ndi kutentha kwa forging kulikonse ndi chimodzimodzi monga n'kotheka. Ngodya zakuthwa ndi mbali zotulukapo za kupangirako zimathanso kusinthidwa kukhala ngodya zamapazi kapena ma chamfers, kuti zotsatira zomwezo zitha kupezeka.
Kuti mudziwe zambiri, ndikukulimbikitsani kuti mupite ku tsamba lathu la webusayiti
Ngati izi zikuwoneka zosangalatsa kapena mukufuna kudziwa zambiri, mungandidziwitse za kupezeka kwanu kuti tithe kukonza nthawi yoyenera kuti tilumikizane kuti tigawane zambiri? Musazengereze kutumiza imelo padella@welongchina.com.
Tithokozeretu.
