一、前言气动系统是以压缩空气作为能源的传动系统。它由气源、执行元件、控制元件、传感元件、辅助装置组成。气动技术已应用于许多工业部门。它较之机械传动系统、电子控制系统、液压系统,具有许多其它能源不能比拟的优点(如净化环境等),将得到越来越多的应用。目前气动技术一般都是用作机械设备的传动和控制系统。但是一台机械设备除了实现其 I. Introduction Pneumatic system is compressed air as the energy of the transmission system. It consists of gas source, the implementation of components, control components, sensor components, auxiliary devices. Pneumatic technology has been used in many industrial sectors. It is more and more applications than mechanical transmission system, electronic control system, hydraulic system, with many other energy can not match the advantages (such as clean environment, etc.). Pneumatic technology is currently used as a general mechanical transmission and control systems. But a mechanical device in addition to achieve it
