| 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 was used to analyze stress and strain distributions of the adjustment blade in different operations. Hydraulic moment, centrifugal moment and friction moment that must be overcome by adjustment blades were also calculated. |
| |
| Keywords: | adjustable axial-flow pump blade stress strain moment of resistance |
