多缸单往复系统中障碍信号的分析与探讨

THE ANALYSIS OF THE OBSTACLE SIGNALS IN SINGLE-RECIPROCATING MULTI-CYLINDER SYSTEM

介绍多缸单往复行程程序控制回路的设计方法之一———信号—动作状态图法 ,针对这一设计方法中的障碍信号的排除方法进行了讨论 ,尤其强调了制约信号、中间记亿元件的控制信号的灵活选择 ,简单而且直观 ,由此而设计的气动回路控制准确 ,使用和维护修都很方便。

This paper introduces Signal-action Status Chart which is one of design methods of loop control procedure in the single-reciprocating multi-cylinder system.Furthermore the paper expounds how to eliminate the obstacle signals in Signal-action Status Chart.The author emphasizes on choosing restrictive signal and control signal of middle memorial component flexibly and makes it work simply and comprehensibly.Her model of pneumatic loop system can be controlled accurately and also can be operated and modified easily.
