Design optimization of a domestic centrifugal pump using Taguchi Method

Abstract

This study focuses on optimizing the design of a domestic centrifugal pump through the Taguchi method, aiming to enhance its performance. Experimental data on pump performance, including total head, efficiency, and suction specific speed, were collected and analyzed. The effects of three design parameters—impeller diameter, blade angle, and volute tongue angle—were investigated using ANOVA. The analysis revealed that impeller diameter had the most significant influence on pump performance, followed by volute tongue angle and blade angle. Optimal performance was achieved with a 55 mm impeller diameter, 25° blade angle, and 20° volute tongue angle. These findings provide valuable insights for engineers seeking to improve centrifugal pump performance, highlighting the importance of impeller diameter in particular. By optimizing design parameters, significant enhancements in pump performance can be achieved, leading to more efficient and effective domestic centrifugal pumps.
