摘要
In order to optimally design an impeller of centrifugal and mixed-flow pumps in which a driving shaft of a motor is coupled in a central portion thereof to thereby receive the torque of the motor, and the shapes and angles of blades including a hub and a shroud vary with the change in the diameter of the driving shaft, an optimal design method for an impeller of centrifugal and mixed-flow pumps comprises the following steps: determining a design specification of the impeller; determining the specific speed of the impeller; determining design variables for the impeller including designing the meridian plane which expresses the shape of a blade to generate a three-dimensional shape of the impeller and designing a blade angle which expresses the blade angle of the impeller; extracting an optimal shape of the impeller including determining major design variables affecting the design target value which is the efficiency of the impeller and determining conditions for optimal design variables which can optimize the design target value by response surface methodology; and comparing the optimal shape of the impeller and that of a reference impeller having required performance and functionizing trends of the design variables according to the change in the diameter of the driving shaft of the motor at the same specific speed.;COPYRIGHT KIPO 2016
