本文着重介绍气动程序控制回路的一种简便、易懂的设计方法。这种方法是根据工作程序要求,用画线图的方式来进行回路设计的,故称信号-动作线图法即X-D线法。应用此方法不仅能较快地拟定设计方案,同时也便于检查回路设计的合理性与正确性。这种方法对刚开始搞气路设计的人来说,使用起来尤其方便。 This article focuses on a simple, easy-to-understand design methodology for pneumatic program control loops. This method is based on the requirements of the working procedure, with the way of drawing lines to the circuit design, it is called the signal - line graph method that X-D line method. The application of this method can not only quickly design a design, but also easy to check the loop design is reasonable and correct. This method is especially convenient for those who are just beginning to engage in gas circuit design.
