【 摘 要 】

Centrifugal multi-stage pump hydraulic efficiency and, as a result, its optimal mode of operation depend primarily on guide vanes. Radial crossover guide vanes were optimized in order to increase pump hydraulic efficiency. Three geometric parameters and the number of guide vane channels were chosen as optimization parameters, and pump hydraulic efficiency was chosen as the criterion. Automatic parameterized design method produced 128 design models; hydraulic efficiency in work mode was calculated with the help of hydrodynamic simulation. Optimization brought about significant increase of pump hydraulic efficiency.
