摘　　要：优化离心泵叶片结构是改善其性能参数的有效途径。叶片的尾部结构与泵内液体的流动状况存在一定关系,而泵内的流动状况很大程度上影响着离心泵的压强分布和空化性能。为进一步优化离心泵的空化性能,以一定数量的叶片为前提,优化泵内3种叶片的尾部结构进行泵内的流场计算和空化计算,以期得到抗空化性能更好的叶片结构。Optimization of centrifugal pump blade structure is an effective way to improve its performance parameters.It is considered that there is a certain relationship between the tail structure of the blade and the flow condition of the liquid in the pump,and the flow condition in the pump greatly affects the pressure distribution and cavitation performance of the centrifugal pump.In order to further optimize the cavitation performance of the centrifugal pump,the tail structure of three kinds of blades in the pump was optimized on the premise of a certain number of blades,and the flow field calculation and cavitation calculation in the pump were carried out,so as to obtain a blade structure with better anti-cavitation performance.
