Kev piav qhia
Magnetic Powder Inspection yog ib qho pf lub nondestructive nrhiav kom paub cov defects ntawm ferromagnetic cov ntaub ntawv los ntawm tsub zuj zuj ntawm magnetic hmoov nyob rau hauv lub leaky magnetic teb nyob ze ntawm lub defect.Cov workpieces ua los ntawm cov khoom sib nqus xws li hlau thiab hlau yog magnetized, thiab cov yam ntxwv. ntawm cov hluav taws xob sib nqus hluav taws xob ntawm qhov chaw tsis xws luag tuaj yeem pom qhov pom ntawm qhov tsis xws luag ntawm cov khoom kuaj pom raws li cov khoom sib nqus sib nqus. Hauv kev lag luam, kev kuaj xyuas qhov tsis zoo ntawm cov hlau nplaum tuaj yeem siv rau kev tshuaj xyuas zaum kawg ntawm cov khoom tiav kom ntseeg tau tias tsis muaj qhov tsis xws luag yuav tshwm sim ntawm qhov chaw ua haujlwm tom qab ntau cov txheej txheem ua haujlwm (xws li vuam, hlau kho cua sov, sib tsoo). Nws kuj tseem tuaj yeem siv rau kev tshuaj xyuas cov khoom lag luam semi-tiav kom pom cov teeb meem uas twb muaj lawm.
Nta
Magnetic Powder Inspection muaj txiaj ntsig zoo rau kev tshuaj xyuas qhov tsis xws luag xws li cov kab nrib pleb ntawm cov khoom siv hlau lossis cov khoom ua haujlwm. Cov khoom siv uas xav tau thiab cov haujlwm muaj feem xyuam yog qhov yooj yim. Nws muaj kev soj ntsuam ceev ceev thiab siab rhiab heev, uas yooj yim rau ntawm qhov chaw tsis pom kev ntawm cov khoom loj thiab cov khoom ua haujlwm, thiab cov nqi kuaj xyuas tsawg. Nws yuav tsum tau muab sau tseg tias txoj kev no tsuas yog siv tau rau cov ntaub ntawv ferromagnetic, thiab tsuas tuaj yeem tshawb xyuas qhov ntev thiab cov duab ntawm qhov tsis xws luag, tab sis nws yog qhov nyuaj los txiav txim siab lawv qhov tob. Rau cov castings yuav tsum tau soj ntsuam, qhov saum npoo yuav tsum du ua ntej kuaj.
