Abstract
This paper aims to study the influence of double-acting blade pump stator curve on pump performance and its optimized design. Structure, features and advantages of double-action blade pump are summarized, and the geometric features, constituent elements and design principles of the stator curve are analyzed in detail. Then, the mechanism of the stator curve on pump flow uniformity, suction performance, vibration and noise, pressure and efficiency. On this basis, the paper further proposes the optimal design strategy of the stator curve, including fine designing the shape and length of the transition curve, improving the flow uniformity, designing the adjustable stator curve and reducing the energy loss in the process of oil pressure. Through theoretical analysis and optimization design practice, this study provides scientific basis and practical guidance for the performance improvement of dual-acting blade pump, which helps to promote the progress and development of pump technology and improve the overall efficiency of industrial fluid machinery.
