摘　　要：某型喷油泵柱塞偶件使用过程中出现结构破坏及穴蚀,为提高其使用寿命,改善穴蚀情况,使用有限元强度仿真软件和三维流体计算软件,分别对其进行结构强度优化计算及穴蚀改善计算。结果表明,结构改进后,柱塞套结构应力下降,穴蚀情况得到明显改善。Structural damage and cavitation corrosion occurred during the use of plunger coupling parts of a certain type of flue pump. In order to improve its service life and cavitation corrosion condition, used ansys to optimize the structural strength and cavitation improvement calculation respectively. The results show that the structural stress of the plunger sleeve decreases and the cavitation corrosion is obviously improved.
