液压系统噪声的分析与防治

Analysis and Prevention on Noise of Hydraulic System

针对液压系统噪声源和传递辐射噪声的渠道,在液压系统设计过程中,分别对液压泵的选择、电动机冷却风扇和通风口形状设计、液压泵和电动机的安装、液压阀的选择、阀芯的设计和节流口的设计、油箱的选择和设计、油管的选用及管路的安装设计,提出了相应的措施。结果表明,这些措施能够从根本上降低和防止液压系统的噪声。

Aiming at the sources of noise of hydraulic system and roads of transmitting radiant noise, in the process of designing hydraulic system, we should adopt appropriate measures to the selection of hydraulic pump, cooling fan of electric engine and shape design of air vent, and the installation of hydraulic pump and electric engine, the selection of hydraulic valves, design of spool and orifice port of valve, the selection and design of reservoir, and the selection and installation design of pipe. The result shows that the measures we have taken could reduce and prevent noise of hydraulic system thoroughly.
