Ⅰ.Dab tsi yog qhov kev sim uas tsis muaj kev puas tsuaj?
Feem ntau hais lus, kev ntsuam xyuas tsis muaj kev puas tsuaj siv cov yam ntxwv ntawm lub suab, lub teeb, hluav taws xob thiab cov hlau nplaum los xyuas qhov chaw, qhov loj, qhov ntau, qhov xwm txheej thiab lwm yam ntaub ntawv cuam tshuam ntawm qhov ze-nto lossis sab hauv qhov tsis xws luag ntawm qhov chaw ntawm cov khoom yam tsis muaj kev puas tsuaj rau cov khoom nws tus kheej. .Non-destructive test aims kom paub txog cov txheej txheem ntawm cov ntaub ntawv, xws li seb lawv puas tsim nyog los yog muaj kev pab cuam lub neej, tsis muaj kev cuam tshuam rau yav tom ntej kev ua tau zoo ntawm cov ntaub ntawv.Cov kev kuaj uas tsis yog-destructive muaj xws li ultrasonic test, electromagnetic test, thiab sib nqus. Kev kuaj particle, ntawm cov Ultrasonic Test yog ib qho ntawm feem ntau siv txoj kev.
Ⅱ.Tsib txoj kev sim uas tsis muaj kev puas tsuaj:
Ultrasonic Test yog ib txoj hauv kev uas siv cov yam ntxwv ntawm ultrasonic nthwv dej los nthuav tawm thiab muaj kev cuam tshuam hauv cov ntaub ntawv txhawm rau txheeb xyuas qhov tsis xws luag sab hauv lossis cov khoom txawv teb chaws hauv cov ntaub ntawv. Nws tuaj yeem ntes ntau yam tsis xws luag, xws li tawg, qhov pores, suav nrog, xoob, thiab lwm yam. Ultrasonic flaw detection yog tsim rau ntau yam ntaub ntawv, thiab tseem tuaj yeem ntes cov thickness ntawm cov ntaub ntawv, xws li hlau, non-metals, composite cov ntaub ntawv, thiab lwm yam. yog ib txoj hauv kev uas feem ntau siv hauv kev sim tsis muaj kev puas tsuaj.
Vim li cas cov phaj tuab tuab, cov kav dej tuab thiab cov kab loj-ntev puag ncig zoo dua rau UT xeem?
① Thaum lub thickness ntawm cov khoom yog loj, muaj peev xwm ntawm sab hauv tsis xws luag xws li pores thiab tawg yuav nce raws li.
② Forgings yog tsim los ntawm cov txheej txheem forging, uas yuav ua rau muaj qhov tsis xws luag xws li qhov pores, suav nrog, thiab tawg hauv cov khoom.
③Thick-walled kav thiab loj-inch puag ncig rods feem ntau yog siv nyob rau hauv xav tau engineering lug lossis cov xwm txheej uas muaj kev ntxhov siab. UT xeem tuaj yeem nkag mus tob rau hauv cov khoom siv thiab pom muaj qhov ua tsis zoo sab hauv, xws li cov kab nrib pleb, suav nrog, thiab lwm yam, uas yog qhov tseem ceeb rau kev ua kom muaj kev ncaj ncees thiab kev nyab xeeb ntawm cov qauv.
2.PENETRANT TEST txhais
Muaj feem xyuam rau UT Test thiab PT Test
UT xeem yog tsim nyog rau kev soj ntsuam cov khoom tsis xws luag, xws li pores, inclusions, tawg, thiab lwm yam. UT test tuaj yeem nkag mus rau cov khoom tuab thiab kuaj xyuas qhov tsis xws hauv cov khoom los ntawm emitting ultrasonic nthwv dej thiab tau txais cov cim qhia.
PT xeem yog tsim rau kev kuaj xyuas qhov tsis xws luag ntawm cov khoom siv, xws li pores, inclusions, cracks, thiab lwm yam. PT kev ntsuam xyuas tso siab rau cov kua nkag mus rau hauv cov kab nrib pleb lossis qhov tsis xws luag thiab siv cov xim tsim los qhia qhov chaw thiab cov duab ntawm qhov tsis xws luag.
Kev xeem UT thiab PT xeem muaj lawv tus kheej qhov zoo thiab qhov tsis zoo hauv kev siv tswv yim. Xaiv txoj kev sim tsim nyog raws li qhov kev xav tau sib txawv thiab cov yam ntxwv ntawm cov khoom siv kom tau txais cov txiaj ntsig zoo dua.
3.Eddy Current Test
(1) Taw qhia rau ET Test
ET Test siv lub hauv paus ntsiab lus ntawm electromagnetic induction coj ib tug alternating tam sim no-carrying test coil ze rau ib tug neeg xyuas pib workpiece los tsim eddy tam sim no. Raws li cov kev hloov pauv hauv eddy tam sim no, cov khoom thiab cov xwm txheej ntawm lub workpiece tuaj yeem raug xam.
(2) Qhov zoo ntawm ET Test
ET Test tsis xav tau kev sib cuag nrog lub workpiece lossis nruab nrab, qhov kev tshawb nrhiav ceev ceev heev, thiab nws tuaj yeem kuaj cov ntaub ntawv tsis yog xim hlau uas tuaj yeem ua rau eddy tam sim no, xws li graphite.
(3) Cov kev txwv ntawm ET Test
Nws tsuas tuaj yeem txheeb xyuas qhov tsis xws luag ntawm cov khoom siv hluav taws xob. Thaum siv los ntawm hom kauj rau ET, nws tsis tuaj yeem txiav txim siab qhov chaw tshwj xeeb ntawm qhov tsis xws luag ntawm qhov ncig.
(4) Cov nqi thiab cov txiaj ntsig
ET Test muaj cov cuab yeej yooj yim thiab ua haujlwm yooj yim. Nws tsis xav tau kev cob qhia nyuaj thiab tuaj yeem ua qhov kev sim ntawm lub sijhawm tiag tiag ntawm qhov chaw.
Lub hauv paus ntsiab lus ntawm PT xeem: tom qab lub nto ntawm ib feem yog coated nrog fluorescent dye los yog xim dye, lub penetrant tuaj yeem nkag mus rau hauv qhov chaw qhib qhov tsis xws luag nyob rau hauv lub sij hawm ntawm capillary nkaus; Tom qab tshem tawm qhov ntau dhau ntawm qhov nkag mus rau ntawm qhov chaw, ib feem tuaj yeem thov tus tsim tawm rau saum npoo. Ib yam li ntawd, nyob rau hauv qhov kev txiav txim ntawm lub capillary, tus tsim tawm yuav nyiam cov penetrant khaws cia hauv qhov tsis xws luag, thiab cov penetrant yuav nkag mus rau hauv tus tsim tawm. Nyob rau hauv ib lub teeb ci (ultraviolet lub teeb los yog lub teeb dawb), cov cim ntawm qhov nkag mus ntawm qhov tsis xws luag yuav tshwm sim. , (daj-ntsuab fluorescence lossis ci liab), yog li kuaj pom cov morphology thiab kev faib tawm ntawm qhov tsis xws luag.
4.Magnetic Particle Test
Sib Nqus Particle Testing" yog ib qho kev siv ntau yam tsis muaj kev puas tsuaj rau kev kuaj xyuas qhov chaw thiab qhov chaw ze ntawm cov khoom siv hluav taws xob, tshwj xeeb tshaj yog rau kev kuaj cov kab nrib pleb. subsurface flaws.
5.RADIOGRAPHIC TEST
(1) Taw qhia rau RT Test
X-rays yog electromagnetic tsis muaj zaus heev, tsis tshua muaj wavelength luv, thiab siab zog. Lawv tuaj yeem nkag mus rau cov khoom uas tsis tuaj yeem nkag los ntawm lub teeb pom kev, thiab ua rau muaj kev cuam tshuam nrog cov khoom siv thaum lub sijhawm nkag mus.
(2) Qhov zoo ntawm RT Test
RT Test tuaj yeem siv los txheeb xyuas qhov tsis xws ntawm cov ntaub ntawv, xws li lub qhov hws, cov kab nrib pleb, thiab lwm yam, thiab tseem tuaj yeem siv los ntsuas cov qauv kev ncaj ncees thiab cov khoom siv sab hauv.
(3) Lub hauv paus ntsiab lus ntawm RT Test
RT Test kuaj pom qhov tsis xws luag hauv cov khoom los ntawm emitting X-rays thiab tau txais cov cim qhia. Rau cov ntaub ntawv tuab, UT xeem yog ib qho txiaj ntsig zoo.
(4) Cov kev txwv ntawm RT Test
RT Test muaj qee yam kev txwv. Vim nws cov yam ntxwv wavelength thiab lub zog, X-rays tsis tuaj yeem nkag mus rau qee yam khoom, xws li txhuas, hlau, stainless hlau, thiab lwm yam.
