本文在上篇“关于孔板和管的液流”的基础上,更详细的讨论实际的元件以及配管组合的流量特性。流量的一般表达式有关气动元件等的流量大小,在国内是采用“有效截面积”来表示的。它是假设如图44所示的“喷嘴”(入口取R 倒角的“孔板”)和“气动元件”具有等效的流量特性,且以喷嘴的最小流路截面积(单位mm~2)表示流量大小的。同样,在采用这个有效截面积来计 This article discusses in more detail the actual component and flow characteristics of the pipe assembly, based on the previous article, “Flows on Orifices and Tubes.” The general expression of flow About the flow of pneumatic components, etc., in the country is the use of “effective cross-sectional area” to represent. It is assumed that the “nozzle” (inlet “R” chamfer “orifice plate”) and the “pneumatic element” have the equivalent flow characteristics as shown in Fig. 44 and that the minimum flow passage cross-sectional area ) Said the size of the flow. Again, use this effective cross-sectional area to calculate
