摘　　要：采用微库仑法、光谱法、光学显微镜、扫描电镜、X射线衍射仪等手段对芳烃抽提系统的3105泵叶轮进行了失效分析。结果表明,叶轮失效的主要原因是材料组织粗大以及氧腐蚀和冲蚀磨损交互作用的结果。Failure reasons of impellers in a pump of an aromatic hydrocarbon extracting system were analyzed by means of mierocoulometrie detector, spectroscopic methodology, optical microscopy, scanning electron microscope and X ray diffraction. The major reasons for impeller failure were interactive action of coarse mierostrueture and oxygen corrosion as well as erosion-corrosion.
