摘　　要：针对研制出的阀配流式柱塞泵样机,使用噪声与振动测试仪测量了阀配流式柱塞泵组在各测量点上的噪声信号,并对常压和额定工况下泵组的噪声信号进行1/3倍频程频谱分析。分析了噪声的主要来源并提出了相应的解决方法。The noise signal of developed prototype of flat valve type piston pump is measured by vibration and noise tester from some testing points. 1/3 octave spectrum is used to analyze the noise signal in atmospheric pressure and the rated operating condition. The major sources of the noise are found out and the solution to reduce the noise is proposed.
