利用2通道声发射分析仪(PAC3000/3004,USA)和瞬态波形存贮器(BC-VI型),通过波导杆对热裂化反应塔的进料口和合成氨装置高压变换管道对接焊缝的材质以及液流的泄漏进行在线监测。经停机后的检查表明,声发射在线监测是有效的。
Using a 2-channel acoustic emission analyzer (PAC3000 / 3004, USA) and transient waveform memory (Model BC-VI), the inlet of the thermal cracking column and the high pressure shift line butt weld of the ammonia plant Material and flow leakage on-line monitoring. After the shutdown checks show that acoustic emission monitoring is effective online.
