Iyo induction quenching inzira yekudzima iyo inoshandisa thermal mhedzisiro inogadzirwa neiyo induction ikozvino inopfuura nepakati pekugadzira kupisa pamusoro uye yenzvimbo chikamu chekugadzira kune yekudzima tembiricha, ichiteverwa nekukurumidza kutonhora. Munguva yekudzima, iyo yekugadzira inoiswa mune yemhangura chinzvimbo sensor uye yakabatana kune inochinjika ikozvino yeyakagadziriswa frequency kugadzira electromagnetic induction, izvo zvinokonzeresa induced ikozvino pamusoro peiyo forging inopesana neyazvino muinduction coil. Iyo yakavharwa loop inoumbwa neiyi induced current pamwe nepamusoro pekugadzira inonzi eddy current. Pasi pekuita kweiyo eddy ikozvino uye kushorwa kwekuzvigadzira pachayo, simba remagetsi rinoshandurwa kuita simba rinopisa pamusoro pekugadzira, zvichiita kuti pasi rikurumidze kupisa kusvika pakuyerera kwemvura, mushure mezvo kuumbwa kunobva kwakurumidza uye nekukurumidza. yakatonhodzwa kuti iwane chinangwa chekudzima pamusoro.
Chikonzero eddy currents anogona kuwana kupisa kwepamusoro kunotemerwa nekugovera maitiro ekuchinjanisa ikozvino mune conductor. Aya maitiro anosanganisira:
- Skin Effect:
Kana yakananga ikozvino (DC) ichipfuura nemuchina conductor, density iripo inofanana pachikamu chemuchinjiko wemutyairi. Nekudaro, kana kuchinjanisa ikozvino (AC) kuchipfuura, kugovera kwazvino pachikamu chemuchinjiro weconductor hakuna kuenzana. Ikozvino density yakakwira pamusoro peiyo conductor uye yakadzikira pakati, ine density iripo inoderera zvakanyanya kubva kumusoro kusvika pakati. Ichi chiitiko chinozivikanwa se ganda mhedzisiro ye AC. Iyo yakakwirira frequency ye AC, iyo inonyanya kutaurwa iyo ganda mhedzisiro. Induction heat quenching inoshandisa hunhu uhu kuti uwane mhedzisiro yaunoda.
- Proximity effect:
Kana maconductor maviri ari pedyo achipfuura nepano, kana kutungamira kwazvino kwakafanana, iyo induced back inogoneka padivi pemakodhakita maviri ndiyo yakakura nekuda kwekudyidzana kwealternating magnetic fields anogadzirwa nawo, uye ikozvino inofambiswa kuenda rutivi rwekunze rwemutyairi. Pane zvinopesana, kana hutungamiri huripo hunopesana, ikozvino inofambiswa kune yakatarisana nedivi remakonduri maviri, ndiko kuti, kuyerera kwemukati, chiitiko ichi chinodaidzwa kuti hukama hwepedyo.
Munguva yekupisa kwekupinza, iyo induced ikozvino pakugadzira inogara iri kune yakatarisana neyazvino muinduction ring, saka ikozvino iri pairi induction ring inonangana nekuyerera kwemukati, uye ikozvino pane inopisa fogi iri muinduction ring. yakanyanyisa pamusoro pepamusoro, iyo inoguma yehutano hwepedyo uye ganda rinowedzera.
Pasi pekuita kwekuita kwepedyo, kugoverwa kweiyo induced ikozvino pamusoro peiyo yekugadzira yunifomu chete kana gaka riri pakati peiyo induction coil uye forging yakaenzana. Naizvozvo, iyo forging inofanirwa kutenderedzwa nguva nenguva panguva yekupisa yekupisa kuti ibvise kana kuderedza kusaenzana kwekupisa kunokonzerwa nekusaenzana gap, kuitira kuti uwane yunifomu yekudziya kupisa.
Mukuwedzera, nekuda kwekuita kwepedyo, chimiro chenzvimbo inopisa pakugadzira inogara yakafanana nechimiro cheiyo induction coil. Naizvozvo, kana uchigadzira iyo induction coil, zvinodikanwa kuita kuti chimiro chayo chifanane nechimiro chenzvimbo yekudziya yekugadzira, kuitira kuti uwane iri nani kupisa mhedzisiro.
- Circulation Effect:
Kana kuchinjanisa ikozvino kuchipfuura nemumhete-yakaita semhete kana helical conductor, nekuda kwekuita kwealternating magnetic field, density iripo pamusoro pekunze kweconductor inoderera nekuda kwekuwedzera self-inductive back electromotive force, nepo mukati iyo mhete inowana yakanyanya density iripo. Ichi chiitiko chinozivikanwa se circulation effect.
Mhedzisiro yekutenderera inogona kuvandudza kugona kwekudziya uye nekumhanyisa paunenge uchipisa nzvimbo yekunze yechidimbu chakaumbwa. Zvisinei, hazvina kunaka pakupisa maburi emukati, sezvo kutenderera kwemhepo kunokonzera ikozvino muinductor kuti iende kure nepamusoro pechigamba chakagadzirwa, zvichiita kuti kuderedzwa kwakanyanya kwekupisa uye kunonoka kupisa. Naizvozvo, zvinodikanwa kuisa magineti zvinhu zvine yakakwira permeability pane inductor kuti uvandudze kupisa kwekuita.
Iyo yakakura chiyero cheaxial kureba kweinductor kusvika kuhupamhi hwemhete, iyo inonyanya kutaurwa kutenderera kwekuita. Nokudaro, chikamu chemuchinjikwa cheinductor chinonyatsoitwa rectangular; chimiro che rectangular chiri nani pane sikweya, uye chimiro chedenderedzwa ndicho chakaipisisa uye chinofanira kudzivirirwa zvakanyanya sezvinobvira.
- The sharp Angle effect:
Kana zvikamu zvakabudikira zvine makona akapinza, mipendero uye diki curvature radius inopisa mukati me sensor, kunyangwe kana gaka riri pakati pe sensor nekugadzira rakaenzana, iyo magnetic field line density kuburikidza nemakona akapinza uye zvikamu zvakabuda zvekugadzira zvakakura. , iyo induced current density yakakura, kukurumidza kupisa kunokurumidza, uye kupisa kunowedzera, izvo zvichaita kuti zvikamu izvi zviwedzere uye kunyange kupisa. Chiitiko ichi chinodaidzwa kuti sharp Angle effect.
Kuti udzivise kupinza kweAngle maitiro, kana uchigadzira iyo sensor, gaka riri pakati pe sensor uye rakapinza Angle kana convex chikamu chekugadzira chinofanirwa kukwidziridzwa zvakafanira kudzikisa kusungirirwa kweiyo magineti simba mutsara ipapo, kuitira kuti kupisa nekumhanya uye tembiricha yekugadzira kwese kwese kwakafanana sezvinobvira. Makona akapinza uye zvikamu zvinoputika zvekugadzira zvinogonawo kuchinjwa kuva tsoka dzemakumbo kana chamfers, kuitira kuti mhedzisiro imwechete inogona kuwanikwa.
