Kev tshuaj xyuas ntawm cov laj thawj yog vim li cas qhov ntsuas qhov ntsuas ultrasonic thickness tsis tso tawm
Nyob rau hauv kev siv ntawm ultrasonic thickness gauges, tshwj xeeb tshaj yog nyob rau hauv kev saib xyuas ntawm nyob rau hauv-kev pab cuam cov khoom, yog hais tias tus nqi taw qhia yog distorted thiab deviates los ntawm qhov tseeb thickness, uas ua rau cov pipeline (cov cuab yeej) zais kev phom sij, cov yeeb nkab fittings yog hloov raws li cov ntaub ntawv tsis raug, ua rau muaj ntau yam khoom pov tseg. Mattel yuav piav qhia rau koj txog vim li cas vim li cas thiaj li tsis muaj nqi zaub lossis tus nqi flickering erratically:
(1) Qhov roughness ntawm lub workpiece yog loj heev, ua rau tsis zoo coupling ntawm lub sojntsuam thiab kev sib cuag nto, tsis tshua muaj reflected echo, thiab txawm tsis muaj peev xwm tau txais ncha teeb liab. Feem ntau ntawm cov khoom siv thiab cov kav dej hauv kev pabcuam yog qhov chaw-corroded, thiab cov nyhuv coupling yog qhov tsis zoo.
(2) Lub vojvoog ntawm curvature ntawm lub workpiece yog me me heev, tshwj xeeb tshaj yog thaum ntsuas cov thickness ntawm cov kav me me. Txij li qhov saum npoo ntawm cov kev sojntsuam siv feem ntau yog tiaj tus thiab kev sib cuag nrog lub ntsej muag nkhaus yog qhov chaw sib cuag lossis kab sib cuag, lub suab sib txuas yog qis (tsis zoo coupling).
(3) Qhov chaw kuaj pom thiab qhov chaw hauv qab tsis yog sib npaug, lub suab tsis sib luag thaum ntsib qhov chaw hauv qab, thiab qhov kev sojntsuam tsis tuaj yeem tau txais lub teeb liab hauv qab.
(4) Vim yog cov qauv tsis sib xws lossis cov nplej ntxhib ntawm cov hlau castings thiab cov hlau austenitic, tawg tawg loj heev tshwm sim thaum ultrasonic tsis dhau los ntawm lawv. Lub ultrasonic tsis tawg pleb propagate raws txoj kev nyuaj, uas tej zaum yuav annihilate lub echoes thiab ua rau tsis muaj zaub. .
(5) Muaj qee qhov hnav ntawm qhov chaw sojntsuam. Qhov saum npoo ntawm feem ntau siv thickness ntsuas probes yog ua los ntawm acrylic resin. Kev siv lub sij hawm ntev yuav ua rau kom lub ntsej muag roughness, ua rau txo qis rhiab heev, ua rau tsis pom lossis flickering.
(6) Muaj ntau qhov chaw corrosion nyob tom qab ntawm cov khoom raug kuaj. Vim tias muaj cov kab xeb thiab xeb ntawm sab nraud ntawm cov khoom ntsuas, lub suab tsis muaj zog, ua rau kev nyeem ntawv hloov pauv tsis tu ncua, thiab nyob rau hauv qhov xwm txheej hnyav yuav tsis muaj kev nyeem ntawv.
