Research on Hydrodynamic Noise of Multistage CentrifugalPump

摘要

The multistage centrifugal pump is mainly used for urban water supply and residential water, which not only achieves excellent hydraulic performance, but also has higher requirements for noise reduction. This paper focuses on the calculation of the hydrodynamic noise of multistage centrifugal pump, including the calculation of flow field and the calculation of sound field. Then, the calculation results were verified experimentally in this paper to provide some references for the relative researchers.
