Abstract

The influence of the parameters on the vibrations for a centrifugal pump is investigated under the consideration of the fluid excitation force in this paper. The responses of the centrifugal pump during the operation were mostly generated by the fluid excitation force. It is difficult to simulate accurately and make prediction of this coupling vibration in a rigorous analytical method. The finite element model was established in this article with consideration of the effect of the fluid excitation. Based on the modal dynamics method, the analysis is carried out to study on the effect of the parameters such as the flow rate, the blade number, the exit installation angle and the outside diameter of impeller on the frequency-response curves. The results show that there exists an optimal blade number value for a better effect of vibration reduction; the design of the outside diameter should consider the response to get a better damping. The research work is meaningful for the parametric designation and the safe check for the centrifugal pumps.
