Nrog rau kev txhim kho tas mus li ntawm kev lag luam muaj feem xyuam, ntau thiab ntau lub tuam txhab pom tias tom qabshuttering hlau nplaumyog siv rau ib lub sij hawm ntawm lub sij hawm, yuav muaj pom tseeb demagnetization tshwm sim, uas yuav ua rau ib co teeb meem yog hais tias tus pwm tsis kho zoo. Qee qhov laj thawj rau demagnetization ntawm lub thawv sib nqus:
1. Kub
Feem ntau ntawm cov hlau nplaum kaw cov hlau nplaum yog tsim los ntawm sintered NdFeB cov khoom siv hlau nplaum ruaj khov. Cov xwm txheej sib txawv tuaj yeem xaiv NdFeB cov ntaub ntawv ntawm qib sib txawv. Nws tuaj yeem pom tias qhov kub siab tshaj plaws ntawm cov khoom siv sintered NdFeB tuaj yeem ncav cuag 230 degrees, thiab qhov ntsuas kub ntawm cov khoom siv tsawg kawg yog 80 degrees.
2. Tsis tuaj yeem haum nrog lub rooj pwm
Thaum lub hauv paus hlau nplaum ntawm lub pob zeb Shuttering Magnet nyob rau hauv lub xeev ua hauj lwm, lub tuav nto ntawm lub hauv qab ntawm lub magnetic block yog ze ze rau lub steel pwm platform, thiab yog ruaj khov. Txawm li cas los xij, thaum muaj cov khoom txawv teb chaws (xws li pob zeb, hlau filings, zaj duab xis, thiab lwm yam) nyob rau hauv qab ntawm cov hlau nplaum thaiv, uas tsis tuaj yeem haum nrog lub platform, lub zog tuav yuav poob qis heev.
3. Cov hlau nplaum sab hauv lub cev puas lawm
Lub cev lub cev ntawm sintered Ndfeb cov ntaub ntawv yog ib qho nyuaj thiab nkig, nkig thiab yooj yim rau corrode, yog li cov hlau nplaum tsis tuaj yeem cuam tshuam nrog lwm tus quab yuam, thiab txheej txheej ntawm cov hlau nplaum tsis tuaj yeem raug puas tsuaj. Yog tias cov hlau nplaum hauv cov hlau nplaum thaiv tau tawg thiab lub cev puas lawm, lub zog nqus ntawm cov hlau nplaum yuav txo qis.
Yog li ntawd, nyob rau hauv cov ntaub ntawv ntawm assembling ib tug hlau nplaum thiab ib tug hlau bar rau hauv ib tug hlau nplaum, qhov saum npoo ntawm cov hlau nplaum yuav tsum tsawg li sai tau rau lub dav hlau ntawm cov hlau bar, uas yuav ua tau zoo kom tsis txhob sib tsoo, thiab cov hlau nplaum nws tus kheej kuj xav tau ib tug tej txheej tiv thaiv kom tsis txhob muaj kev puas tsuaj rau lub cev thiab corrosion.
