随着机械化自动化程度不断提高,液压系统日趋复杂,用传统的继电器逻辑电路控制液压系统,需要的电气元件数目越来越多,电气柜庞大昂贵。液压逻辑程序器是一种电液程序控制元件,用它控制执行部件程序动作时可以省掉中间继电器和电磁铁,简化电气控制系统,节约电能源。本文介绍八步液压程序器的工作原理、结构及集成逻辑回路的设计。其主要技术指 With the increasing degree of mechanization and automation, the hydraulic system is becoming more and more complex. With traditional relay logic control of the hydraulic system, more and more electrical components are needed and the electrical cabinet is huge and expensive. Hydraulic logic programmer is a kind of electro-hydraulic program control element, it can save the energy of the electric control system by simplifying the electrical control system and saving the intermediate relay and the electromagnet when it is used to control the execution of program. This article describes the eight-step hydraulic programmer working principle, structure and design of integrated logic circuit. Its main technical means
