摘要

离心泵的设计和非设计性能在很大程度上取决于地质力学参数。本研究旨在通过优化叶轮-蜗壳相互作用的三个地质力学参数来提高性能。本优化是使用田口方法与数值方法相结合进行的。基于数值分析和实验分析,对设计工况和非设计工况下的基础泵和优化泵进行了比较。数值结果表明,与基础泵相比,优化后的泵通过叶轮内均匀的压力分布、朝向叶片前缘的低压区减小以及叶轮-蜗壳相互作用区的总压力稳定,表现出了更好的性能。实验结果表明,优化后的泵运行范围更广,其最佳效率点(BEP)在流量、扬程和效率方面分别比基础泵高10%、5%和12%。

Optimization of Centrifugal Pump Based on Impeller-Volute Interactions
The design and off-design performance of a centrifugal pump largely depends on geomechanical parameters. This study aims at enhancing the performance by optimizing three geomechanical parameters of impeller-volute interactions. The present optimization is carried out using the Taguchi method combined with a numerical approach. A comparison between the base and optimized pumps is presented under the design and off-design conditions based on numerical and experimental analyses. The numerical results reveal that, compared to the base pump, the optimized pump shows the improved performance through uniform pressure distribution in the impeller, the reduced low-pressure region towards a blade’s leading edge, and the stable total pressure at the impeller-volute interaction zone. The experimental results suggest that the optimized pump covers a wider range of operation, and its best efficiency point (BEP) is 10%, 5%, and 12% higher in flow rate, head, and efficiency, as compared to the base one.
