A Review and Prospect of Research on Centrifugal Pump Noise

Abstract

This paper presents a comprehensive review of the current state and development trends in the research on centrifugal pump noise. It first analyzes the primary sources of noise in centrifugal pumps, including mechanical noise, fluid-induced noise, and structural noise. Subsequently, it discusses in detail the main research methods employed in this field, covering experimental measurement techniques, numerical simulation approaches, and theoretical analysis methods. Finally, the paper provides a prospective outlook on future research directions, highlighting emerging trends such as interdisciplinary research, intelligent monitoring and control technologies, the application of novel materials and structural designs, as well as green design and sustainable development. This review aims to offer valuable insights and references for the continued advancement of research in centrifugal pump noise.
