Abstract:Due to the cracks of axial pump blades in Dongshen pump station, analysis on flow dynamics, structure strength and vibration for the pump runner, is finished by finite element method. Furthermore, the vibration and pressure fluctuation of the pump at site are measured. The measures are adopted such as cutting the sharp angles between the blades outlet and the runner hub, welding support bands with the edges of the suction side of the blades. The cracks are effectively prevented.
