Qhov defects ntawmcev squareyuav txo tau cov tsos thiab zoo ntawm cov khoom. Yuav ua li cas kom paub qhov defects ntawmcev square? Tom ntej no, peb yuav piav qhia txog cov txheej txheem defect nrhiav pom ntawm qhov qiscev squarehauv kev nthuav dav
1 、 Eddy kuaj tam sim no.
Eddy kev sim tam sim no suav nrog cov qauv ntsuas tam sim no, kev ntsuas tam sim no nyob deb, ntsuas ntau zaus eddy tam sim no thiab ntsuas pulse eddy tam sim no. Siv eddy tam sim no sensors kom paub cov hlau, ntau hom teeb liab yuav raug tsim raws li hom thiab cov duab ntawm qhov tsis xws luag ntawm cov raj square. Nws muaj qhov zoo ntawm kev tshawb pom qhov tseeb, siab nrhiav kom pom tseeb thiab nrawm nrawm nrawm. Nws tuaj yeem kuaj xyuas qhov chaw thiab qis ntawm cov yeeb nkab uas tau kuaj xyuas yam tsis muaj kev cuam tshuam los ntawm cov impurities xws li cov roj stain nyob rau saum npoo ntawm cov yeeb nkab ntsuas square. Qhov tsis zoo yog tias nws yooj yim los txiav txim qhov tsis xws luag yog qhov tsis xws luag, qhov kev kuaj pom tsis tseeb yog siab, thiab qhov kev kuaj pom tsis yooj yim kho.
2.Ultrasonic kuaj
Thaum lub ultrasonic nthwv dej nkag mus rau hauv cov khoom thiab ua tau raws li qhov tsis xws luag, ib feem ntawm acoustic yoj yuav tshwm sim. Lub transceiver tuaj yeem txheeb xyuas cov nthwv dej uas muaj kev cuam tshuam thiab txheeb xyuas qhov tsis xws luag thiab raug. Kev kuaj ultrasonic feem ntau yog siv los kuaj forgings. Kev tshawb pom rhiab heev yog qhov siab, tab sis cov kav dej nrog cov duab tsis yooj yim rau kev ntes. Nws yog qhov yuav tsum tau ua kom lub ntsej muag ntawm lub raj tshuaj ntsuam xyuas muaj qee qhov smoothness, thiab qhov sib txawv ntawm qhov kev sojntsuam thiab qhov chaw kuaj xyuas yuav tsum tau ntim nrog tus neeg sawv cev sib txuas.
3.Magnetic particle kuaj
Lub hauv paus ntsiab lus ntawm magnetic particle txoj kev yog kom paub magnetic teb nyob rau hauv square tube khoom. Raws li kev sib cuam tshuam ntawm qhov tsis xws luag los ntawm magnetic teb thiab magnetic particle, thaum muaj discontinuities los yog tsis xws luag nyob rau hauv lub nto los yog nyob ze ntawm lub nto, cov magnetic teb kab yuav nyob rau hauv lub zos deformed ntawm lub discontinuities los yog tsis xws luag, thiab sib nqus ncej yuav generated. Nws qhov zoo yog cov cuab yeej siv tsawg dua, kev ntseeg siab thiab muaj zog pom. Qhov tsis zoo yog tus nqi ua haujlwm siab, kev faib tawm tsis raug thiab kev tshawb nrhiav qeeb.
4.infrared tau
Lub induction tam sim no yog tsim nyob rau saum npoo ntawm lub square raj los ntawm high-frequency induction kauj. Qhov cuam tshuam tam sim no yuav ua rau thaj chaw tsis raug siv hluav taws xob ntau dua, ua rau qhov kub thiab txias hauv cheeb tsam. Siv infrared los ntsuas qhov kub thiab txias hauv zos thiab txiav txim siab qhov tob. Infrared detection feem ntau yog siv rau kev tshawb nrhiav ntawm flattened defects, tab sis tsis yog rau kev tshawb nrhiav ntawm qhov chaw irregularities.
5.Magnetic flux to test
Cov txheej txheem magnetic flux to testing method for square tubes zoo ib yam li cov magnetic particle test method, thiab nws siv tau ntau yam, rhiab heev thiab kev ntseeg tau muaj zog dua li cov magnetic particle test method.
