Pib ntawm Cov Cua Kub Induction

Qhov yooj yim ntawm induction cua sov tau to taub thiab ua ntaub ntawv thov los ntawm cov 1920s. Lub sijhawm Tsov Rog Thoob Ntiaj Teb thib 2, lub tshuab tau tsim los ua kom tau raws li qhov yuav tsum tau ua rau lub sijhawm muaj kev kub ntxhov rau txoj kev yoojyim, txhim khu kev ruaj ntseg rau cov cav hlau. Tsis ntev los no, qhov tseem ceeb ntawm lean manufacturing cov tswv yim thiab qhia txog kev ua kom zoo tswj tau coj mus rau kev tshawb nrhiav kev siv tshuab induction, nrog rau kev tsim kho ntawm kev tswj meej, txhua lub xeev induction cua sov cov khoom siv hluav taws xob.

Induction cua kub qhov chaw nyob hauv ib qho khoom hluav taws xob (tsis yog sib txawv hlau) thaum tus kwv tso rau hauv qhov sib txawv ntawm kev sib nqus. Induction cua sov yog vim yog lub qe thiab qhov teeb meem ntawm qhov tsim txom.

Hysteresis kev poob tsuas tshwm sim hauv cov ntaub ntawv sib nqus xws li cov hlau, nickel, thiab lwm yam. Hysteresis poob hais tias qhov no tshwm sim los ntawm kev sib txhuam ntawm cov molecules thaum cov khoom siv yog magnetized ua ntej nyob rau hauv ib qho kev taw qhia, thiab tom qab ntawd nyob rau lwm yam. Cov lwg me me tej zaum yuav muab xam tias yog cov hlau nplaum me me uas tig mus ncig nrog txhua qhov kev rov qab ntawm kev taw qhia ntawm lub chaw sib nqus. Ua haujlwm (lub zog) xav kom tig rov los. Lub zog hloov mus rau hauv tshav kub. Tus nqi ntawm kev siv nyiaj ntawm lub zog (lub zog) nce nrog qhov nce ntawm qhov thim rov qab (zaus).

Eddy-poob peev txheej tam sim no tshwm sim hauv ib qho kev coj cov khoom hauv ib qho chaw sib txawv. Qhov no ua rau nqe lus hais, txawm tias cov ntaub ntawv tsis muaj ib qho ntawm cov khoom sib nqus feem ntau cuam tshuam nrog hlau thiab hlau. Piv txwv yog tooj liab, tooj dag, txhuas, zirconium, hlau tsis xeb hlau, thiab uranium. Eddy tam sim no yog qhov hluav taws xob hloov tam sim no los ntawm kev hloov pauv nyob rau hauv cov khoom ntawd. Raws li lawv lub npe cuam tshuam, lawv tshwm sim ntws ncig hauv cov khaub zig dej ntawm eddies tsis pub dhau lub cev huab hwm coj cov khoom. Eddy-poob kev poob yog qhov tseem ceeb tshaj li kev pheej hmoo ntawm hysteresis hauv kev muab cov cua sov. Nco ntsoov tias induction cua sov yog thov rau cov ntaub ntawv tsis-nqus, qhov tsis muaj hysteresis poob tshwm sim.

Rau cov cua sov ntawm cov cua ntawm qhov sib zog, forging, yaj, los yog lwm yam hom phiaj uas yuav tsum tau kub dua Curie qhov kub, peb tsis tuaj yeem vam khom nqi. Hlau loses nws cov khoom sib nqus saum toj no kub no. Thaum cov hlau rhuab hauv qab Curie taw tes, qhov txiaj ntsig ntawm hysteresis feem ntau yog li ntawd me me uas nws yuav tsum tau ignored. Rau tag nrho cov tswv yim, kuv2R ntawm cov kab dej ntawm tus cwj pwm yog tib txoj kev uas hluav taws xob ua hluav taws xob xa tau rau hauv tshav kub rau kev siv cua sov.

Ob qho yooj yim rau induction cua sov tshwm sim:

  • Ib tug hloov magnetic teb
  • Ib qho khoom siv hluav taws xob uas muab tso rau hauv cov hlau nplaum
