摘要
对 1 5 0Y1 5 0× 2离心油泵主轴断裂原因进行了分析 ,分析表明其主轴失效的主要原因是材质不符合设计要求。
The cause for main shaft fracture of 150Y150×2 centrifugal oil pump is analyzed. It is thought that the main cause lies in that the material does not meet design requirements and there are a stress concentration and metallurgical defects at the root of thread notch.
