新型径向柱塞泵降噪机理分析

An Analysis of the Noise Reduction Mechanism of the New Radial Piston Pump

新型径向柱塞泵的噪声明显低于其它类型的液压泵，本文以液压元件产生机械噪声和流体噪声的机理为基础，从新型径向柱塞泵的结构上进行分析，总结其噪声低的主要原因。

The noise of the new radial piston pump is obvi- ously much lower than that of other types of pumps. The paper, on the basis of the research into the mechanism of the mechanical and fluid noises produced by hydraulic parts, analyses the struc- ture of the new radial piston pump and gives the reasons for its low noises.
