5 Summary of the method

5.1 The phenomenon of acoustic emission caused by leakage The fluid stored in the closed equipment leaks out through the leakage hole due to the pressure difference. Gasification and collision of solid particles produce mechanical waves that propagate outward, that is, the phenomenon that leakage produces acoustic waves, also known as the generalized acoustic emission phenomenon. Book The method detects the leakage of closed equipment and determines the leakage location by collecting and analyzing the acoustic emission signal. Figure 1 shows the schematic diagram of the acoustic emission signal generated by leakage and the principle of acoustic emission leakage detection. The continuous acoustic emission signal generated by leakage can be regarded as a significantly enhanced background noise. During the leakage process, the transient changes of pressure fluctuations near the leakage point are different, and the resulting acoustic emission signal has have a wider spectral range. ......
