Koj txoj kev sim ua tsis yog li cas?
Feem ntau hais lus, tsis yog kev ua txhaum kev sim ua cov yam ntxwv, hluav taws xob kom pom qhov chaw nyob ze lossis loj hlob ntawm cov khoom uas tsis muaj kev ua phem rau nws tus kheej .Non-Kev sim ua kom pom cov txheej txheem kev ua haujlwm ntawm cov ntaub ntawv, tsis muaj kev cuam tshuam rau kev sim ua haujlwm tom ntej, tsis tas yuav tsum muaj kev pab cuam tom ntej no Kuaj kuaj, ntawm qhov kev xeem ntawv ultrasonic yog ib txoj kev siv ntau tshaj plaws.
Ⅱ.five ib txwm tsis muaj kev sim ua kev sim ua txhaum:
Kev sim ultrasonic yog ib txoj kev uas siv cov yam ntxwv ntawm ultrasonic tsis los nthuav tawm thiab muaj kev cuam tshuam rau cov ntaub ntawv los tshawb txog cov khoom siv sab hauv lossis cov khoom txawv teb chaws nyob rau hauv cov ntaub ntawv. Nws tuaj yeem kuaj ntau yam tsis xws luag, xws li cov kab nrib pleb, ntxeem tau rau ntau yam khoom siv, thiab muaj peev xwm ntes tau rau cov ntaub ntawv tuab, thiab muaj cov hlau, cov khoom siv sib xyaw, thiab lwm yam. Nws yog ib txoj kev siv feem ntau hauv kev sim ua tsis yog-ua kev puas tsuaj.
Vim li cas cov hlau tuab tuab, cov kav hlau tuab-walled
① Thaum cov tuab tuab ntawm cov khoom yog loj, qhov ua tau ntawm sab hauv tej yam xws li pores thiab cov kab nrib pleb yuav nce raws li.
②forgings yog tsim los ntawm cov txheej txheem forging, uas yuav ua rau tsis xws luag xws li pores, suav, thiab tawg nyob rau hauv cov khoom siv.
Cov kav dej uas muaj ntsa ntau thiab cov pas nrig loj thiab cov kab ke uas tau siv nyob rau hauv cov qauv tsim khoom loj lossis cov xwm txheej muaj kev ntxhov siab ntau. Siv kev sim tuaj yeem nkag mus rau hauv cov khoom siv tsis taus, xws li cov kab nrib pleb, uas yog qhov tseem ceeb los ua kom muaj kev ncaj ncees thiab kev nyab xeeb ntawm cov qauv.
2.penrant txhais tes xeem
Muaj cov xwm txheej siv rau cov ntaub ntawv xeem thiab PT sim
Kev sim ntsuas yog haum rau kuaj cov khoom siv sab hauv, xws li cov khoom siv thickness tuaj yeem nkag mus rau hauv cov khoom siv ultrasonic thiab tau txais cov cim.
PT qhov kev ntsuas yog haum rau ntes nto tsis zoo rau ntawm cov khoom siv, cov kab nrib pleb, kev siv cov xim xim kom pom qhov chaw thiab cov duab ntawm qhov tsis xws luag.
Cov xeem xeem ntawv thiab PT kev xeem muaj lawv tus kheej zoo thiab qhov tsis zoo hauv cov ntawv thov kev siv. Xaiv cov qauv ntsuas uas tsim nyog raws li cov kev xav tau sib txawv thiab cov yam ntxwv kom tau txais cov txiaj ntsig zoo.
3.eddy kev ntsuam xyuas tam sim no
(1) Taw qhia rau ET sim
Et sim siv cov hauv paus ntsiab lus ntawm indectromagnetic induction kom coj kev sim tam sim no coil ze rau tus neeg xyuas kev ua haujlwm los tsim eddy dej. Raws li cov kev hloov pauv ntawm Eddy so, cov khoom thiab cov xwm txheej ntawm workpiece tuaj yeem ua tau zoo.
(2) Qhov zoo ntawm thiab sim
ET qhov kev sim tsis xav tau kev sib cuag nrog lub workpiece lossis qhov kev tshawb nrhiav tau nrawm heev, thiab nws tuaj yeem ntxias eddy keej, xws li graphite.
(3) Cov kev txwv ntawm thiab kev sim
Nws tuaj yeem ntes cov khoom sib txawv ntawm cov ntaub ntawv. Thaum siv cov kauj dhau los ntawm cov kauj rau thiab, nws yog tsis yooj yim sua kom txiav txim siab txog qhov chaw tshwj xeeb ntawm qhov tsis xws luag ntawm lub ncig.
(4) cov nqi thiab cov txiaj ntsig
Et kev sim muaj cov khoom siv yooj yim thiab kev ua haujlwm yooj yim. Nws tsis xav tau kev cob qhia nyuaj thiab tuaj yeem ua sai sai ntawm kev sim lub sijhawm ntawm lub xaib.
Tus txheej txheem tseem ceeb ntawm PT kev sim: tom qab ntawm ntu yog coated nrog fluorescent zas xim lossis xim xim, tus neeg quav muag tuaj yeem nkag mus rau qhov tsis xws luag nyob rau hauv ib lub sijhawm ntawm capillary. Tom qab tshem tawm cov neeg chim siab tshaj plaws ntawm cov npoo ntawm ib feem, qhov feem tau tuaj yeem thov tus tsim tawm mus rau saum npoo. Ib yam li ntawd, nyob rau hauv qhov kev txiav txim ntawm capillary, tus tsim tawm yuav nyiam cov neeg mob siab khaws cia hauv qhov tsis xws luag, thiab tus neeg ua haujlwm yuav pom rov qab mus rau tus tsim tawm. Nyob rau hauv ib qho teeb meem lub teeb (ultraviolet teeb lossis lub teeb dawb), cov kab ntawm cov penetrant ntawm qhov tsis xws luag yuav raug tso tawm. , (Lub fluorescence lossis ci liab), yog li tshawb pom cov morphology thiab faib khoom tsis xws luag.
4.MAGNE PALFLE TESTING
Sib nqus Partle kuaj "yog ib qho kev sim ua tsis zoo rau kev ntes cov khoom sib nqus rau cov khoom sib nqus, tso cai rau cov khoom sib nqus zoo, tso cai rau kev pom zoo ntawm subsurface flaws.
5.Raderiographic ntsuam xyuas
(1) Taw qhia rau RT Kev Ntsuas
X-Rays yog electromagnetic nthwv hluav taws xob nrog lub siab heev, uas tsis muaj zog heev, thiab lub zog tsis ntev. Lawv tuaj yeem nkag mus rau cov khoom uas tsis tuaj yeem nkag los ntawm pom kev, thiab yauv nyom nrog cov ntaub ntawv thaum lub sij hawm nkag mus.
(2) Qhov zoo ntawm RT kev kuaj
RT kev ntsuas tuaj yeem siv los tshawb xyuas cov khoom siv sab hauv, xws li pores, suav nrog cov txheej txheem kev ncaj ncees thiab cov khoom siv hauv cov ntaub ntawv zoo.
(3) Lub hauv paus ntsiab lus ntawm RT kev kuaj
RT kuaj xyuas qhov tsis xws luag nyob rau hauv cov khoom los ntawm emitting x-rays thiab tau txais cov cim. Rau cov ntaub ntawv tuab, siv kev sim yog txhais tau tias zoo.
(4) cov kev txwv ntawm RT kev kuaj
RT kev ntsuam xyuas muaj qee qhov kev txwv. Vim nws lub wavelength thiab cov zog zog, xoo hluav taws xob tsis tuaj yeem txig qee cov ntaub ntawv, xws li coj, hlau, hlau stainless, thiab lwm yam.
