PushPuller System ? TPU2 Probe Pusher will be selected to use. ? The pushpuller system includes three main subassemblies: ? - the pushpuller device, ? - the control station, ? - the hose connecting the positioner. The calibration tube is fixed on line to the end of the conduct on the positioner side. 渦流檢測應用 2022/3/13 29 ? The Eddy Current Data Acquisition System ? Teatom TEDDY ACQ Data Acquisition Network will be selected to use for this purpose. It is satisfied to the following requirements from Purchaser. ? The data acquisition system prises the following subassemblies: ? - the multifrequency generator, ? - signal digitazation system, ? - eddy current signal processing system, ? - the recorders. 渦流檢測應用 2022/3/13 30 ? The Eddy Current Probes ? - Description ? The probes with and without a permanent mag must enable implementation of the multifrequency method. ? Four types of bobbin probe, CF155NAF32WB, CF155NAF32WBI, CF145PAF32WB and CF145PAF32WBI and the + point type MRPC, probe will be selected to use for different situations. 渦流檢測應用 2022/3/13 31 渦流檢測應用 2022/3/13 32 ? 聲發(fā)射技術是根據(jù)結(jié)構內(nèi)部發(fā)出的應力波判斷結(jié)構內(nèi)部損傷程度的一種無損檢測方法,它與超聲、 X射線等常規(guī)無損檢測方法主要區(qū)別在于聲發(fā)射技術是一種動態(tài)無損檢測方法,它能連續(xù)監(jiān)視結(jié)構內(nèi)部損傷的全過程。當物體(試件或產(chǎn)品)受外力或內(nèi)應力作用時,缺陷處或結(jié)構異常部位因應力幾種而產(chǎn)生塑性變形,其儲存能量的一部分以彈性應力波的形式釋放出來,這種現(xiàn)象稱為聲發(fā)射,而用電子學的方法接收發(fā)射出來的應力波,進行處理和分析以評價缺陷發(fā)生、發(fā)展的規(guī)律和尋找缺陷位置的技術統(tǒng)稱為聲發(fā)射技術。 ? 除極少數(shù)材料外,金屬和非金屬材料在一定條件下都有聲發(fā)射
