气动元件的流通能力,与其工作介质的性质和温度,元件前后的压力大小以及元件内部结构等因素有关。它是元件的特性指标之一,它反映了元件的容量大小,也是用户选择元件通径的重要依据。因此,一直受到人们的重视。然而过去各国用于表示气动元件流通能力的特性参数值都不一样,没有统一的标准。为了寻求更合理的参数值,西欧各国很早就进行了这方面的研究工作。1971年1月 F.E.Sanville 提出“测定气动元件流量特性的新方法”即临界
The flow capacity of pneumatic components, with the nature of its working medium and temperature, the pressure before and after the components as well as the internal structure of components and other factors. It is one of the characteristics of the component index, which reflects the size of the component size, but also an important basis for the user to select the component path. Therefore, it has always been people’s attention. However, the past countries used to represent the flow of pneumatic components of the characteristics of the parameters are not the same value, there is no uniform standard. In order to seek more reasonable values of parameters, Western European countries have conducted research in this area very early. January 1971 F.E.Sanville proposed “a new method of measuring the flow characteristics of pneumatic components,” that is critical
