本文在理论分析和实验的基础上,对叶片泵噪声的首要影响因素——压力撤换进行了分析,所建立的叶片工作腔压力撤换数学模型,对于主要声源的改善与眉毛槽的设计有一定的参考价值。此项研究,在降低产品噪声方面已取得初步成效。 Based on the theoretical analysis and experiments, this paper analyzes the pressure change, the primary influencing factor of the vane pump noise. The mathematical model of the pressure change of the vane working chamber is established to improve the main sound source and the design of the eyebrow groove The reference value. This study has achieved initial results in reducing product noise.
