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 kuaj ultrasonic (UT), kuaj cov hlau nplaum sib nqus (MT), ntsuas dej 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 cov nthwv dej uas cuam tshuam, 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 yog qhov loj, piv txwv li, kev tshawb pom qhov tob 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 txheeb ze ntawm qhov tsis xws luag tuaj yeem txiav txim siab;
3. Cov cuab yeej siv tau yooj yim, muaj kev nyab xeeb rau kev khiav lag luam, thiab yooj yim kom paub txog kev tshuaj xyuas tsis siv neeg.
Qhov tsis txaus:
Nws tsis yog ib qho yooj yim los soj ntsuam cov workpieces nrog cov duab nyuaj, thiab qhov saum npoo yuav tsum tau kuaj xyuas kom muaj qee qhov kev sib tw, thiab cov couplant yuav tsum tau siv los sau 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
Tom qab cov khoom siv ferromagnetic thiab cov khoom ua haujlwm tau magnetized, vim muaj qhov tsis sib xws, cov kab hlau nplaum sib nqus ntawm qhov chaw thiab nyob ze ntawm qhov chaw ua haujlwm yog distorted hauv zos, thiab cov xaim hlau nplaum yog tsim, uas adsorbs cov hmoov sib nqus siv 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 kev pom kev pom.
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 ntes cov khoom siv 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 20 degree 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 ib tug 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 cov 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 sawv cev 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 ntsuas kev nkag mus yog:
1. Ntau yam ntaub ntawv tuaj yeem kuaj tau;
2. Nws muaj rhiab heev;
3. Cov zaub yog intuitive, kev khiav hauj lwm yog yooj yim, thiab nrhiav tau 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 ua los ntawm cov khoom ntxeem tau thiab cov khoom ua haujlwm nrog cov khoom ntxhib;
2. Kev ntsuam xyuas kev nkag mus tsuas tuaj yeem txheeb xyuas qhov kev faib tawm ntawm qhov tsis xws luag, thiab nws yog qhov nyuaj rau kev txiav txim siab qhov tseeb qhov tob ntawm qhov tsis xws luag, yog li nws yog qhov nyuaj rau kev ntsuas ntau qhov tsis xws. Cov txiaj ntsig kev tshawb pom kuj tseem cuam tshuam los ntawm tus neeg teb xov tooj.
X-ray kuaj
Hom kawg, kev kuaj pom hluav taws xob, yog vim X-rays yuav ploj tom qab dhau los ntawm cov khoom irradiated, thiab cov ntaub ntawv 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 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 duab hluav taws xob yog ib qho yooj yim khaws thiab muaj traceability.
3. Visually tso saib cov duab thiab hom tsis xws luag.
4. Qhov tsis zoo: Qhov faus qhov tob ntawm qhov tsis xws luag tsis tuaj yeem nyob, thiab qhov kev tshawb 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 xeem yog tsim los xyuas qhov tsis xws luag ntawm qhov chaw; ntawm lawv, kev ntsuam xyuas magnetic particle tsuas yog siv rau kev kuaj xyuas cov khoom sib nqus, thiab kev ntsuas nkag mus tsuas yog txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhaws.
