Abstract

In order to better understand the law of vibration and noise of a double-suction centrifugal pump,a double-usction centrifugal pump was taken as a study object.Based on the indirect boundary element method,(IBEM),a LMS Virtual-Lab computational platform was adopted to compute the forced vibration response of the pump due to flow based on modes of the pump shell.Then the forced vibration equations and the IBEM acoustic wave equations were used to form the coupled equations,these coupled equations were solved to obtain the distribution of sound pressure level and the direction distribution of sound pressure level of the double-suction centrifugal pump outside radiation sound field under the hydraulic turbine working condition and the pump working condition. The results showed that the dipole sound source is the main sound source of fluid-induced noise; the volute tongue unsteady pressure fluctuation is the main noise source; the blade frequency and its frequency multiplication are the main induced frequencies; the pump shell′s resonances appear; so,the acoustic-vibro interaction can not be neglected.The study results revealed the sound-vibration interaction law for the outside radiation sound field of a double-suction centrifugal pump under hydraulic turbine working condition and the pump working condition,and provided a theoretical basis for further study.
