储罐内置式声发射多传感器投放装置创新设计
|
摘要
储罐底板腐蚀声发射在线检测技术目前被广泛使用,但对于大型储罐,会存在检测盲区,内外部相结合的声发射在线检测技术是解决这一问题的有效方法。为此,设计储罐内置式声发射多传感器投放装置,该装置可以携带多枚声发射传感器,并精准投放到大型储罐内部指定位置,通过内部传感器与外部传感器联合监测,实现大型在用储罐底板腐蚀内外部结合的全域检测。
Acoustic emission technique of tank bottom corrosion has been widely used,but for large storage tanks,there will be a blind spot of detection,the on-line acoustic emission technique,which combines internal and external sound,is an effective method to solve this problem. Therefore,the multisensory launching device of acoustic emission built-in storage tank,the device can carry a plurality of acoustic emission sensors,and can be delivered accurately into the large tank in the specified position,through joint monitoring of internal sensor and external sensors,it can achieve a comprehensive detection combining the internal and external of the large-scaled and in-used storage tank bottom corrosion.
