| Abstract: | The internal three-dimensional turbulent flow of adjustable axial-flow pump arrangement was simulated, and the force acting
on the blade surface was calculated under different operating conditions. Based on the calculated results, finite element
method (FEM) was adopted to analyze stress and strain distributions of the adjustment blade in different operations. Hydraulic
moment, centrifugal moment and friction moment which must be conquered by adjusting the blades were also calculated.
