Yuav ua li cas tiv thaiv demagnetization ntawmib daim hlau nplaum ruaj khovHauv cov twj sib nqus, ces peb yuav tsum xub txheeb xyuas cov laj thawj yog vim li cas hlau nplaum demagnetization, uas tuaj yeem muab faib ua cov xwm txheej hauv qab no:
1. Kev siv kub yog tsis tsim nyog.
2. Lub sijhawm ua haujlwm ntev lub taub hau.
3. Cov kav dej tsis raug cai.
4. Sliding bearing hnav tsis hloov raws sijhawm.
5. Sib nqus twj tso kua mis khiav idling.
6. Cov kav dej nkag thiab qhov hluav taws xob tau thaiv.
7. Lub rotor qhov chaw yog jammed txawv txav.
8. Cavitation tshwm sim.
Los ntawm cov laj thawj saum toj no, peb tuaj yeem pom tias qhov kub thiab txias yog qhov laj thawj tseem ceeb cuam tshuam rau demagnetization ntawm cov hlau nplaum.
Nws tuaj yeem pom los ntawm demagnetization nkhaus ntawm hlau nplaum:
Thaum qhov kub siab tshaj 150 ℃, zoo tib yamNeodymiun Magnetsyuav nkag irreversible torsion poob;
Thaum qhov kub siab tshaj 250 ℃, cov hlau nplaum ntawm cov khoom siv SmCo hlau nplaum yuav nkag mus rau qhov tsis tuaj yeem torsional poob.
Thaum qhov kub thiab txias tshaj 350 ℃, lubHigh Quality SmCo Magnetyuav nkag mus rau irreversible torsional poob.
