Ntau yam - cov khoom siv, txoj kab uas hla, phab ntsa thickness, kev ceev, thiab cov yeeb nkab vuam los yog txoj kev tsim - txiav txim siab qhov kev xeem zoo tshaj plaws.Cov yam tseem ceeb no tseem cuam tshuam rau kev xaiv ntawm cov yam ntxwv ntawm kev tswj txoj kev siv.
Eddy tam sim no kuaj (ET) yog siv nyob rau hauv ntau daim ntawv thov piping.Qhov no yog qhov kev ntsuas pheej yig uas tuaj yeem siv rau hauv cov kav dej nyias nyias, feem ntau txog li 0.250 nti phab ntsa tuab.Nws yog tsim rau ob qho tib si sib nqus thiab cov khoom tsis sib nqus.
Sensors lossis test coils poob rau hauv ob pawg loj: annular thiab tangential.Circumferential coils tshuaj xyuas tag nrho ntu ntu ntawm cov yeeb nkab, thaum tangential coils tshuaj xyuas tsuas yog thaj tsam weld.
Qhwv spools pom qhov tsis xws luag thoob plaws tag nrho cov khoom xa tuaj, tsis yog thaj chaw vuam, thiab lawv feem ntau ua haujlwm zoo dua ntawm kev tshuaj xyuas qhov ntau thiab tsawg hauv qab 2 ntiv tes.Lawv kuj ua siab ntev rau weld zone displacement.Lub ntsiab qhov tsis zoo yog tias kev hla cov khoom noj los ntawm cov dov zeb yuav tsum muaj cov kauj ruam ntxiv thiab kev saib xyuas tshwj xeeb ua ntej nws dhau los ntawm kev xeem yob.Tsis tas li ntawd, yog tias qhov ntsuas coil nruj rau txoj kab uas hla, qhov vuam tsis zoo tuaj yeem ua rau lub raj sib cais, ua rau muaj kev puas tsuaj rau qhov ntsuas coil.
Tangential tig tshuaj xyuas ib feem me me ntawm qhov ncig ntawm cov yeeb nkab.Hauv daim ntawv thov txoj kab uas hla loj, siv tangential coils es tsis yog twisted coils feem ntau yuav muab lub teeb liab zoo-rau-suab nrov piv (ib qho kev ntsuas ntawm lub zog ntawm lub teeb liab ntsuas piv rau cov teeb liab zoo li qub hauv keeb kwm yav dhau).Tangential coils kuj tsis xav tau cov xov thiab yooj yim rau calibrate tawm ntawm lub Hoobkas.Lub downside yog tias lawv tsuas yog xyuas cov ntsiab lus solder.Haum rau cov kav dej loj loj, lawv kuj tuaj yeem siv rau cov kav dej me me yog tias qhov vuam txoj hauj lwm tswj tau zoo.
Coils ntawm txhua hom tuaj yeem kuaj tau rau kev sib cais.Kev kuaj xyuas tsis raug, tseem hu ua xoom kuaj lossis kuaj qhov sib txawv, txuas ntxiv sib piv cov vuam mus rau qhov chaw nyob ib sab ntawm lub hauv paus hlau thiab nkag siab rau cov kev hloov me me uas tshwm sim los ntawm kev tsis sib xws.Qhov zoo tshaj plaws rau kev kuaj xyuas qhov tsis xws luag xws li pinholes lossis cov welds uas ploj lawm, uas yog thawj txoj hauv kev siv feem ntau cov ntawv yob yob.
Qhov kev sim thib ob, qhov tseeb, pom qhov tsis zoo ntawm kev hais lus.Daim ntawv no yooj yim tshaj plaws ntawm ET xav kom tus neeg teb xov tooj siv hluav taws xob sib npaug ntawm cov khoom siv zoo.Ntxiv nrog rau kev txheeb xyuas cov kev hloov pauv tsis tu ncua, nws tseem pom cov kev hloov pauv ntawm phab ntsa thickness.
Siv ob txoj kev ET no yuav tsum tsis txhob muaj teeb meem tshwj xeeb.Lawv tuaj yeem siv tau ib txhij nrog ib qho kev sim coil yog tias qhov ntsuas tau nruab rau ua li ntawd.
Thaum kawg, qhov chaw ntawm lub cev ntawm tus neeg sim yog qhov tseem ceeb.Cov khoom xws li ambient kub thiab zeb vibrations uas xa mus rau lub raj tuaj yeem cuam tshuam rau qhov chaw.Muab qhov ntsuas coil ntawm ib sab ntawm lub vuam chamber muab tus neeg teb xov tooj tam sim ntawd cov ntaub ntawv hais txog cov txheej txheem vuam.Txawm li cas los xij, cov khoom siv hluav taws xob tiv thaiv hluav taws xob lossis cua txias ntxiv yuav xav tau.Muab qhov ntsuas coil ze rau qhov kawg ntawm lub zeb tso cai rau kev tshawb pom ntawm qhov tsis xws luag los ntawm qhov loj me lossis shaping;Txawm li cas los xij, qhov tshwm sim ntawm kev ceeb toom tsis tseeb yog siab dua vim tias lub sensor nyob ze rau ntawm qhov kev txiav tawm hauv qhov chaw no, qhov uas nws yuav pom kev vibrations thaum sawing lossis txiav.
Ultrasonic kuaj (UT) siv pulses ntawm hluav taws xob lub zog thiab hloov lawv mus rau hauv lub suab nrov zaus.Cov suab nthwv dej no raug xa mus rau cov khoom hauv kev sim los ntawm qhov nruab nrab xws li dej los yog zeb coolant.Lub suab yog kev taw qhia, kev taw qhia ntawm transducer txiav txim siab seb lub kaw lus tab tom nrhiav qhov tsis xws luag lossis ntsuas phab ntsa tuab.Ib txheej ntawm cov transducers tsim cov contours ntawm vuam cheeb tsam.Txoj kev ultrasonic tsis txwv los ntawm lub thickness ntawm cov yeeb nkab phab ntsa.
Txhawm rau siv cov txheej txheem UT ua cov cuab yeej ntsuas, tus neeg teb xov tooj yuav tsum tau taw qhia lub transducer kom nws yog perpendicular rau cov yeeb nkab.Lub suab nthwv dej nkag mus rau sab nraud ntawm cov yeeb nkab, thaws tawm hauv txoj kab uas hla, thiab rov qab mus rau lub transducer.Lub kaw lus ntsuas lub sijhawm thauj mus los - lub sijhawm nws siv lub suab nthwv dej los ntawm txoj kab uas hla sab nraud mus rau sab hauv txoj kab uas hla - thiab hloov lub sijhawm ntawd mus rau qhov ntsuas tuab.Nyob ntawm cov xwm txheej zeb, qhov teeb tsa no tso cai rau kev ntsuas phab ntsa kom raug rau ± 0.001 hauv.
Txhawm rau txheeb xyuas cov khoom tsis xws luag, tus neeg teb xov tooj taw qhia lub sensor ntawm lub kaum oblique.Lub suab nthwv dej nkag los ntawm txoj kab uas hla sab nraud, mus rau sab hauv txoj kab uas hla, rov qab mus rau sab nraud, thiab yog li taug kev raws phab ntsa.Qhov tsis sib xws ntawm cov weld ua rau qhov kev xav ntawm lub suab yoj;nws rov qab rau tib txoj kev mus rau lub converter, uas hloov nws rov qab rau hauv hluav taws xob lub zog thiab tsim ib qho kev pom pom qhia qhov chaw ntawm qhov tsis xws luag.Lub teeb liab kuj dhau los ntawm cov rooj vag tsis zoo uas ua rau lub tswb ceeb toom rau tus neeg teb xov tooj, lossis pib lub tshuab pleev xim uas cim qhov chaw ntawm qhov tsis xws luag.
UT systems yuav siv tau ib qho transducer (los yog ntau lub ntsiab lus transducers) los yog ib theem ntawm cov transducers.
Ib txwm UTs siv ib lossis ntau dua ib lub ntsiab lus sensors.Tus naj npawb ntawm cov probes nyob ntawm qhov xav tau qhov tsis xws luag ntev, kab nrawm thiab lwm yam kev xeem yuav tsum tau ua.
Lub phased array ultrasonic analyzer siv ntau lub ntsiab lus transducer hauv ib lub tsev.Lub kaw lus tswj hluav taws xob tswj cov suab nthwv dej kom kuaj xyuas qhov chaw vuam yam tsis hloov txoj haujlwm ntawm lub transducer.Lub kaw lus tuaj yeem ua cov haujlwm xws li kev kuaj xyuas qhov tsis xws luag, ntsuas phab ntsa tuab, thiab taug qab cov kev hloov pauv hauv cov nplaim taws ntxuav ntawm qhov chaw welded.Cov qauv ntsuas thiab ntsuas no tuaj yeem ua tiav ib txhij.Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias txoj hauv kev phased array tuaj yeem zam tau qee qhov vuam drift vim tias cov array tuaj yeem npog thaj tsam loj dua li cov khoom siv kho qhov muag.
Txoj kev kuaj thib peb uas tsis muaj kev puas tsuaj, Sib Nqus Flux Leakage (MFL), yog siv los ntsuas cov kab loj loj, tuab-walled thiab sib nqus kav.Nws yog qhov zoo rau kev siv roj thiab roj.
MFL siv lub zog DC magnetic teb dhau los ntawm cov yeeb nkab lossis yeeb nkab phab ntsa.Lub zog magnetic teb mus txog tag nrho cov saturation, los yog lub ntsiab lus ntawm ib qho kev nce nyob rau hauv magnetizing quab yuam tsis ua rau ib tug tseem ceeb nce nyob rau hauv sib nqus flux ceev.Thaum sib nqus flux sib tsoo nrog qhov tsis xws luag hauv cov khoom, qhov tshwm sim ntawm qhov sib nqus flux tuaj yeem ua rau nws ya los yog npuas tawm ntawm qhov chaw.
Cov huab cua zoo li no tuaj yeem tshawb pom tau siv lub tshuab hluav taws xob yooj yim nrog cov hlau nplaum.Raws li nrog rau lwm daim ntawv thov magnetic sensing, lub kaw lus yuav tsum muaj kev sib txheeb ntawm cov khoom nyob rau hauv kev sim thiab sojntsuam.Qhov kev txav no yog ua tiav los ntawm kev tig cov hlau nplaum thiab kev sojntsuam sib dhos nyob ib ncig ntawm cov yeeb nkab lossis cov yeeb nkab.Txhawm rau ua kom nrawm nrawm hauv cov kev teeb tsa no, cov khoom siv ntxiv (dua, ib qho array) lossis ob peb arrays yog siv.
Lub rotating MFL thaiv tuaj yeem tshawb pom qhov ntev lossis qhov tsis xws luag.Qhov sib txawv yog nyob rau hauv kev taw qhia ntawm cov qauv magnetization thiab kev tsim ntawm qhov kev sojntsuam.Nyob rau hauv ob qho tib si, lub teeb liab lim tswj cov txheej txheem ntawm kev kuaj xyuas qhov tsis xws luag thiab qhov txawv ntawm qhov chaw ID thiab OD.
MFL zoo ib yam li ET thiab lawv ntxiv ib leeg.ET yog rau cov khoom uas muaj phab ntsa thicknesses tsawg dua 0.250 ″ thiab MFL yog rau cov khoom uas muaj phab ntsa thicknesses ntau dua qhov ntawd.
Ib qho ntawm qhov zoo ntawm MFL dhau ntawm UT yog nws lub peev xwm los kuaj xyuas qhov tsis zoo.Piv txwv li, helical tsis xws luag tuaj yeem tshawb pom tau yooj yim siv MFL.Qhov tsis xws luag hauv qhov kev taw qhia oblique, txawm tias pom tau los ntawm UT, yuav tsum tau teeb tsa tshwj xeeb rau lub kaum ntse ntse.
