气动设备广泛地用于自动控制领域,它能方便地控制构件作直线或旋转运动。 传统的气动设备(气缸和空气马达)是由机械阀或气动阀控制的,其控制程序通常由气动逻辑元件执行,缺点是改变运行程序的灵活性低。因此,可自由编程的电子控制系统是目前这一领域的发展趋势。 气与电之间的联系一向是由电磁阀来完成的。为保持电磁场而加的连续电流会产生热量,其功耗通常为几瓦。同时,电感 Pneumatic equipment is widely used in the field of automatic control, it can easily control the components for linear or rotary motion. Conventional pneumatic equipment (cylinders and air motors) are controlled by mechanical valves or pneumatic valves. The control procedures are usually performed by pneumatic logic elements. The disadvantage is that the flexibility to change the operating procedures is low. Therefore, the freely programmable electronic control system is the current trend in this area. The connection between gas and electricity has always been done by a solenoid valve. The continuous current added to maintain the electromagnetic field generates heat, which typically consumes a few watts. At the same time, inductance
