配流冲击是柱塞泵的主要噪声源.本文以25SCY14-1B 轴向柱塞泵为研究对象,对其配流过程中的压力及流量冲击做了分析与仿真,用微型压力、加速传感器测试了高压、高速旋转工况下泵内柱塞腔压力动态过程及斜盘振动过程,在此基础上对配流冲击机理做了进一步的探讨,并提出以控制流量倒灌冲击为主要降噪优化目标的配流盘阻尼结构设计准则.
The impact of the distribution flow is the main noise source of the piston pump.In this paper, the 25SCY14-1B axial piston pump is taken as the research object, the pressure and flow impact in the process of its distribution is analyzed and simulated, and the micro-pressure and acceleration sensors are used to test the high pressure , The dynamic process of piston pressure in the pump and the swash plate vibration process under the condition of high speed rotation are discussed further on the basis of which the impact mechanism of the flow distribution is further discussed and the valve plate with the control of the flow intrusion as the main noise reduction optimization target Damping structure design guidelines.
