气动逻辑元件是一种新型的自动化基础元件。它具有结构简单、成本低、寿命长等特点,可以在易燃、易爆、多灰尘等恶劣环境中安全可靠的工作。过去,机械加工的自动控制习惯上大都采用电器元件组成控制装置,通过电-气转换来控制气动执行机构(如气缸)动作。但是,电器触点寿命不长,往往容易造成动作失灵,不适宜在易燃、易爆、潮湿等恶劣环境中工作。用气动逻辑元件能组成全气控系统,使控制和执行都采用压缩空气作为动力源,省去了界面(电-气)转换,动作迅速、工作可靠,给使用和维修带
Pneumatic logic element is a new type of automation foundation element. It has the characteristics of simple structure, low cost and long service life, which can work safely and reliably in harsh environments such as flammable, explosive and dusty. In the past, the automatic control of machining mostly used electrical components to form the control device, which controlled the operation of the pneumatic actuator (such as the cylinder) through the electro-pneumatic conversion. However, the electrical contact life is not long, often easily lead to malfunction, not suitable for flammable, explosive, humid and other harsh environments. With pneumatic logic components can be composed of all-pneumatic control system, the control and implementation of the use of compressed air as a power source, eliminating the interface (electricity - gas) conversion, fast action, reliable, to the use and maintenance of the belt
