摘要： 传统的离心式吸鱼泵设计基本上是根据设计经验与相似泵推导设计，导致设计周期长且性能参数无法确定。为了更加快速、精确地设计出不同尺寸类型的吸鱼泵，并估算出离心式吸鱼泵的流量、扬程等性能参数，运用CFturbo设计软件进行参数化设计吸鱼泵，通过CFturbo软件建立吸鱼泵的三维模型，并通过软件内置经验函数优化设计，然后通过CFD流体动力学软件进行数值模拟仿真验证，最终设计出符合性能参数要求的离心式吸鱼泵，实现离心式吸鱼泵的快速研发。

Abstract: The design of traditional centrifugal fish pump is basically based on design experience and similar pump design, resulting in long design cycle and uncertain performance parameters. In order to design fish pumps of different sizes and types more rapidly and accurately and estimate the parameters such as flow and head of centrifugal fish pump, CFturbo design software is used for parametric design of fish pump. CFturbo is used to establish three-dimensional model of fish pump, the experience function is built into the software to optimize the design, then CFD software is used for numerical simulation and verification, and finally centrifugal fish pump meeting the performance parameters is designed to realize its rapid development.
