Kev kuaj tsis muaj kev puas tsuaj yog siv cov yam ntxwv ntawm lub suab, lub teeb, hlau nplaum thiab hluav taws xob los xyuas seb puas muaj qhov tsis xws luag lossis tsis sib xws hauv cov khoom kuaj xyuas yam tsis muaj kev puas tsuaj lossis cuam tshuam rau kev ua haujlwm ntawm cov khoom kuaj xyuas, thiab muab qhov loj, qhov chaw, qhov dav. lub sij hawm rau tag nrho cov kev txhais tau tias los txiav txim siab lub xeev ntawm cov khoom nyob rau hauv kev soj ntsuam (xws li tsim nyog los yog tsis, seem lub neej, thiab lwm yam).
Feem ntau siv cov kev sim uas tsis yog kev puas tsuaj:Kev ntsuam xyuas ultrasonic (UT), kuaj cov hlau nplaum sib nqus (MT), kuaj kua nkag (PT) thiab kuaj X-ray (RT).
Kev kuaj ultrasonic
UT (Ultrasonic Testing) yog ib txoj hauv kev ntawm kev kuaj tsis muaj kev puas tsuaj hauv kev lag luam. Thaum lub ultrasonic nthwv dej nkag mus rau hauv cov khoom thiab ntsib qhov tsis xws luag, ib feem ntawm lub suab nthwv dej yuav raug cuam tshuam, thiab lub transmitter thiab receiver tuaj yeem txheeb xyuas qhov cuam tshuam ntawm nthwv dej, thiab qhov tsis xws luag tuaj yeem kuaj pom tau zoo heev. Thiab nws tuaj yeem tso saib txoj haujlwm thiab qhov loj me ntawm qhov tsis xws luag, thiab ntsuas qhov tuab ntawm cov ntaub ntawv. Qhov zoo ntawm kev kuaj ultrasonic: 1. Lub peev xwm nkag mus tau loj, piv txwv li, qhov kev tshawb pom zoo hauv cov hlau tuaj yeem ncav cuag ntau tshaj 1 meter; 2. Rau qhov tsis xws luag xws li cov kab nrib pleb, interlayers, thiab lwm yam, qhov tsis zoo ntawm qhov kev xav tau yog siab, thiab qhov tob thiab qhov tob ntawm qhov tsis xws tuaj yeem txiav txim siab. kwv tij loj; 3. Cov khoom siv yog lub teeb thiab muaj kev nyab xeeb rau kev khiav lag luam, thiab nws yog ib qho yooj yim kom paub txog kev tshuaj xyuas tsis siv neeg. Qhov tsis zoo: Nws tsis yooj yim rau kev tshuaj xyuas cov khoom ua haujlwm nrog cov duab nyuaj, qhov saum npoo yuav tsum tau kuaj xyuas kom muaj qee qhov kev sib tw, thiab cov couplant yuav tsum tau ua kom tiav qhov sib txawv ntawm qhov kev sojntsuam thiab qhov chaw yuav tsum tau kuaj xyuas kom txaus acoustic. kev sib txuas.
Magnetic particle soj ntsuam
Ua ntej ntawm tag nrho cov, cia peb nkag siab lub hauv paus ntsiab lus ntawm magnetic particle kuaj. Tom qab cov khoom siv ferromagnetic thiab lub workpiece yog magnetized, vim qhov muaj qhov tsis sib xws, cov kab hlau nplaum ntawm qhov chaw thiab nyob ze ntawm qhov chaw ua haujlwm yog distorted hauv zos, thiab cov xaim hlau nplaum yog generated, uas adsorbs magnetic hmoov thov rau. Qhov saum npoo ntawm lub workpiece thiab tsim ib qho chaw sib nqus uas pom nyob rau hauv lub teeb pom kev zoo. cov kab, yog li qhia qhov chaw, cov duab thiab qhov loj ntawm qhov tsis sib xws.
Qhov kev siv tau thiab kev txwv ntawm kev ntsuas magnetic particle yog:
1. Kev tshuaj xyuas cov khoom sib nqus yog tsim nyog rau kev kuaj xyuas qhov tsis sib xws ntawm qhov chaw thiab nyob ze ntawm cov ntaub ntawv ferromagnetic uas me heev thiab qhov sib txawv yog qhov nqaim heev, uas yog qhov nyuaj rau pom qhov muag.
2. Kev tshuaj xyuas cov khoom sib nqus tuaj yeem kuaj xyuas qhov chaw nyob rau hauv ntau yam xwm txheej, thiab tseem tuaj yeem ntes ntau yam ntawm qhov chaw.
3. Cov kab mob xws li cov kab nrib pleb, suav nrog, cov kab plaub hau, cov pob dawb, folds, rwb thaiv tsev txias thiab xoob tuaj yeem pom.
4. Kev ntsuam xyuas cov khoom sib nqus tsis tuaj yeem kuaj xyuas cov ntaub ntawv austenitic stainless hlau thiab welds welded nrog austenitic stainless hlau electrodes, thiab nws tsis tuaj yeem ntes cov khoom tsis sib nqus xws li tooj liab, txhuas, magnesium, thiab titanium. Nws yog ib qho nyuaj rau nrhiav ntiav khawb ntawm qhov chaw, sib sib zog nqus faus qhov thiab delaminations thiab folds nrog lub kaum sab xis tsawg dua 20degreelos ntawm qhov chaw ntawm lub workpiece.
Liquid Penetration Testing
Lub hauv paus ntsiab lus ntawm kev ntsuam xyuas kua nkag mus yog tias tom qab qhov chaw ntawm qhov chaw yog coated nrog fluorescent dyes los yog xim dyes, nyob rau hauv qhov kev txiav txim ntawm capillary rau ib lub sij hawm ntawm lub sij hawm, lub permeate tuaj yeem nkag mus rau hauv qhov chaw qhib qhov tsis xws luag; Tus tsim tawm yog siv rau qhov chaw ntawm qhov chaw.
Ib yam li ntawd, nyob rau hauv qhov kev txiav txim ntawm capillary, tus neeg saib xyuas yuav nyiam cov permeate seem hauv qhov tsis xws luag, thiab cov permeate yuav nkag mus rau hauv tus neeg saib xyuas duab. Nyob rau hauv ib lub teeb ci (ultraviolet teeb los yog lub teeb dawb), cov kab ntawm permeate ntawm qhov tsis xws luag yog tshwm sim. . Qhov zoo ntawm kev ntsuam xyuas penetrant yog: 1. Ntau yam khoom tuaj yeem kuaj pom; 2. Siab rhiab heev; 3. Intuitive zaub, kev ua haujlwm yooj yim thiab tus nqi qis. Qhov tsis zoo ntawm kev ntsuas kev nkag mus yog: 1. Nws tsis haum rau kev tshuaj xyuas cov khoom ua haujlwm ntawm cov khoom ntxeem tau thiab cov khoom ua haujlwm nrog cov khoom ntxhib;
2. Kev ntsuam xyuas kev nkag mus tsuas tuaj yeem tshawb xyuas qhov kev faib tawm ntawm qhov tsis xws luag, thiab nws nyuaj rau txiav txim siab qhov tseeb qhov tob ntawm qhov tsis xws luag, yog li nws yog qhov nyuaj rau kev ntsuas ntau yam tsis xws luag. Cov txiaj ntsig kev tshawb pom kuj tseem cuam tshuam los ntawm tus neeg teb xov tooj.
X-ray kuaj
Qhov kawg, kev kuaj pom hluav taws xob, yog vim tias X-rays yuav ploj tom qab dhau los ntawm cov khoom irradiated, thiab cov khoom sib txawv nrog cov thicknesses sib txawv muaj qhov sib txawv ntawm qhov nqus rau lawv, thiab cov yeeb yaj kiab tsis zoo yog muab tso rau sab nraud ntawm cov khoom irradiated. Cov duab sib thooj raug tsim tawm, thiab cov neeg saib yeeb yaj kiab tuaj yeem txiav txim siab seb puas muaj qhov tsis xws luag hauv cov khoom thiab qhov xwm txheej ntawm qhov tsis xws luag raws li daim duab.
Kev siv thiab kev txwv ntawm kev kuaj hluav taws xob:
1. Nws yog rhiab heev rau kev tshawb nrhiav qhov ntim-hom tsis xws luag, thiab nws yooj yim dua rau tus yam ntxwv ntawm qhov tsis xws luag.
2. Cov yeeb yaj kiab ray yog ib qho yooj yim khaws thiab muaj traceability.
3. Visually tso saib cov duab thiab hom tsis xws luag.
4. Qhov tsis zoo yog tias nws tsis tuaj yeem nrhiav qhov faus qhov tob ntawm qhov tsis xws luag. Nyob rau tib lub sij hawm, nrhiav kom pom thickness yog txwv. Cov yeeb yaj kiab tsis zoo yuav tsum tau xa tshwj xeeb rau kev ntxuav, thiab nws muaj kev phom sij rau tib neeg lub cev thiab tus nqi siab. Tag nrho cov nyob rau hauv tag nrho, ultrasonic thiab X-ray flaw detection yog haum rau flaw nrhiav pom ntawm sab hauv; ntawm lawv, ultrasonic nthwv dej yog tsim rau qhov chaw nrog qhov loj ntawm ntau tshaj 5 hli thiab cov duab tsis tu ncua. X-rays tsis tuaj yeem nrhiav qhov tob ntawm qhov tsis xws luag, thiab muaj hluav taws xob. Sib nqus particle thiab penetrant tshuaj xyuas yog tsim los xyuas qhov tsis xws luag ntawm qhov chaw; Kev tshuaj xyuas cov khoom sib nqus tsuas yog txwv rau kev kuaj xyuas cov khoom sib nqus, thiab kev tshuaj xyuas kev nkag mus tsuas yog txwv rau kev kuaj xyuas qhov chaw qhib qhov tsis xws luag.
