Muaj ntau qhov chaw loj ntawm kev ntsuas qhov yuam kev hauv txheej thickness gauges
Txheej thickness gauge txais tshiab magnetic sense technology, uas yog Hall nyhuv, los ntawm kev kawm txog kev sib raug zoo ntawm Hall voltage thiab ua hauj lwm tam sim no, ntsuas lub magnetic teb ntawm electromagnet, sib nqus permeability, kawm txog kev sib raug zoo ntawm Hall voltage thiab magnetic teb. Qhov no magnetic teb yog ces ua tsis tu ncua. Lub hauv paus ntsiab lus yog siv nyob rau hauv lub txheej thickness gauge saum toj no yog tsis muaj yuav tsum tau kho lub xeem daim. Tshwj xeeb tshaj yog thaum ntsuas qhov arc lossis concave nto ntawm cov khoom yog yooj yim dua thiab siv tau yooj yim.
Txheej thickness gauges siv electromagnetic induction los ntsuas lub thickness ntawm txheej. Qhov kev sojntsuam nyob rau ntawm qhov chaw tsim lub kaw sib nqus sib nqus, uas hloov pauv mus rau qhov sib txawv raws li qhov kev ncua deb ntawm qhov kev sojntsuam thiab cov khoom siv ferromagnetic hloov, ua rau muaj kev hloov pauv hauv cov magnetoresistance thiab inductance ntawm kev sojntsuam coil. Lub hauv paus ntsiab lus no tuaj yeem siv los ntsuas qhov kev ncua deb ntawm qhov kev sojntsuam thiab cov khoom siv ferromagnetic, piv txwv li cov txheej tuab.
Txheej thickness gauge tsis yog siv rau ib ntev lub sij hawm yuav tsum tsis tu ncua nqi thiab tawm los tiv thaiv lub roj teeb xauv, rau ib co me me workpiece los yog tshwj xeeb npog txheej nyias workpiece yog pom zoo kom siv tas mus li ntsuas.
Txheej thickness gauge ntsuas yuam kev tshwm sim los ntawm ob peb yam tseem ceeb:
1. Qhov ntsuas thickness yog ntsuas los ntawm cov qauv ntawm cov khoom sib txawv, cov duab sib txawv. Nyob rau hauv cov qauv sib txawv ntawm lub workpiece, lub magnetic teb faib yuav txawv nrog cov qauv, cov duab, yuav tsim kev ntsuas yuam kev.
2. Cov khoom ntsuas nws tus kheej muaj cov hlau nplaum. Qee cov ntaub ntawv hauv kev ua haujlwm lossis qee cov txheej txheem yuav tsum tau ua, kom cov khoom ntsuas muaj qhov seem hlau nplaum. Vim tias nws qhov kev faib tsis sib npaug, yog li qhov kev ntsuas qhov ua yuam kev tsis sib xws, yuav muaj nyob rau hauv tib lub workpiece ntawm qee qhov ntawm qhov ntsuas tus nqi dheev ua loj lossis me dua.
3. Cov khoom sib txawv ntawm cov khoom siv tib yam kuj tseem tuaj yeem tsim cov kev hloov pauv hauv cov khoom sib nqus, xws li cov khoom siv thiab cov khoom siv hauv nruab nrab, kev faib tawm ntawm cov hlau nplaum tsis zoo ib yam, yuav ua rau kev ntsuas tsis raug.
4. Qhov sib txawv ntawm cov khoom ntsuas, nws qhov sib nqus flux yuav txawv, uas kuj yog ib qho laj thawj rau qhov yuam kev.
5. Qhov sib txawv ntawm qhov loj thiab tuab ntawm cov khoom kuj tuaj yeem ua rau kev ntsuas tsis raug.
6. Qhov saum npoo ntawm cov khoom ntsuas tsis du txaus, uas kuj yog qhov ua rau yuam kev.
