Cov magnetic particle kuaj method of Non-Destructive Kev tshuaj xyuas tau tsim nyob rau hauv Teb Chaws Asmeskas, nyob rau hauv 1930s, raws li ib txoj hauv kev los xyuas cov khoom steel ntawm cov kab ntau lawm. Cov txoj cai ntawm txoj kev yog tias cov qauv yog magnetized los tsim Sib nqus kab zog, los yog flux, nyob rau hauv cov khoom.

Kuj paub, yog dab tsi yog qhov kev ntsuam xyuas magnetic particle siv rau?

Sib Nqus Particle Test (MPT), kuj hu ua Sib nqus Particle Kev tshuaj xyuas, yog ib qho kev kuaj xyuas tsis muaj kev puas tsuaj (NDE). siv rau tshawb xyuas qhov chaw thiab me ntsis subsurface flaws nyob rau hauv feem ntau ferromagnetic cov ntaub ntawv xws li hlau, nickel, thiab cobalt, thiab ib co ntawm lawv cov alloys.

Tsis tas li ntawd, MPT txoj cai yog dab tsi? Txoj cai ntawm MPT Qhov kev sim no hu ua MT (Magnetic Testing) lossis MPT (Magnetic Particle Test), thiab haum rau qhov chaw / subsurface flaw soj ntsuam ntawm ferromagnetic cov ntaub ntawv. Txoj cai ntawm MPT yog raws li nram no: Thaum lub workpiece yuav tsum tau soj ntsuam yog magnetized, magnetic flux yog induced.

Ib yam li ntawd ib tug yuav nug, yuav ua li cas kuaj magnetic particle ua tiav?

Hauv magnetic particle soj ntsuam , ncig magnetization yog siv los xyuas cov kab nrib pleb ntev. dhau los ntawm ib feem los yog los ntawm ib qho hluav taws xob conductor nyob rau hauv ib feem. Lub voj voog Sib nqus teb txiav hla qhov tawg nyiam thiab tuav cov hmoov hlau, los qhia qhov tsis pom kev.

Kev kuaj Magnaflux yog dab tsi?

Magnaflux Magnetic particle soj ntsuam (MPI) kuaj cov khoom siv yog tsim los kom ceev ceev, txhim khu kev qha thiab muaj nuj nqis. Xav paub ntau ntxiv txog yuav ua li cas Magnaflux Cov cuab yeej tshuaj xyuas yog tsim los nrhiav cov cim qhia thiab qhov tsis xws luag xws li qaug zog tawg hauv cov ntaub ntawv ferrous los ntawm txoj kev ntub lossis qhuav mag particle kuaj.
