Thaum nws los txog rau kev ua kom muaj kev nyab xeeb thiab kev ntseeg siab ntawm cov kav dej siv nyob rau hauv ntau qhov kev lag luam, qhov tseem ceeb ntawm cov txheej txheem kev ntsuas tsis muaj kev puas tsuaj yuav tsis tuaj yeem overstated. Ib qho txheej txheem zoo li no yog Pipe Eddy Current Flaw Detection Testing, uas ua lub luag haujlwm tseem ceeb hauv kev kuaj xyuas thiab ntsuas qhov tsis xws hauv cov kav dej hlau thiab tsis yog hlau.
Eddy Current Flaw Detection Testing
Yog li, dab tsi raws nraim yog eddy tam sim no kuaj cov hlab? Yooj yim muab tso, eddy tam sim no kev sim yog ib qho kev sim uas tsis muaj kev puas tsuaj uas siv cov eddy tam sim no txhawm rau txheeb xyuas qhov chaw thiab qhov tsis zoo hauv cov kav dej. Lub hauv paus ntsiab lus tom qab cov txheej txheem no yog ua raws li Faraday txoj cai ntawm electromagnetic induction, qhov twg lub magnetic teb yog induced vim ib tug tam sim no ntws los ntawm ib tug conductor. Qhov no magnetic teb generates eddy tam sim no nyob rau saum npoo ntawm cov yeeb nkab, uas yuav ntsuas tau siv ib tug sojntsuam.
Thaum lub sij hawm eddy tam sim no xeem txheej txheem, ib tug high-frequency alternating tam sim no yog dhau los ntawm cov yeeb nkab coil, uas generates ib tug magnetic teb. Cov eddy tam sim no tsim muaj kev cuam tshuam nrog cov magnetic teb, thiab qhov kev cuam tshuam no hloov pauv qhov kev faib tawm ntawm cov hlau nplaum, uas tuaj yeem tshawb pom los ntawm cov khoom nyob ze. Cov kev sojntsuam cov teeb liab yuav raug ua tiav los txheeb xyuas cov teeb meem uas muaj nyob hauv cov yeeb nkab, xws li cov kab nrib pleb, qhov dej, corrosion, thiab lwm yam kev puas tsuaj.
Eddy tam sim no qhov tsis txaus ntseeg kev kuaj xyuas yog ib qho kev siv cov cuab yeej tam sim no los kuaj xyuas thiab tshuaj xyuas tag nrho cov cheeb tsam.stainless hlau seamless yeeb nkabthiab welded steel kav, tsis muaj kev puas tsuaj rau cov yeeb nkab raug kuaj. Pipe Eddy Current Flaw Detection Testing yog ib qho tseem ceeb ntawm kev soj ntsuam cov txheej txheem uas ua kom muaj kev nyab xeeb thiab kev ntseeg siab ntawm cov kav dej siv hauv ntau qhov kev lag luam.
