一、问题的提出流体在管路中流动时,由于泵出口流量的脉动、阀的启闭以及其他因素的影响,会引起管路系统中流量和压力的脉动。在液压传动系统和流量计量标准装置上,为了衰减这一脉动现象,往往采用稳压容器。那么,从节能的观 First, the question raised When the fluid flow in the pipeline, due to the pump outlet flow pulsation, valve opening and closing and other factors, will cause the flow and pressure piping system pulsation. In hydraulic transmission systems and flow measurement standards, regulators are often used to attenuate this pulsation. Well, from the concept of energy saving
