气缸是气动机械的主要执行元件,提高执行元件的工作速度,是提高各种机械生产效率的重要因素。普通气缸活塞的平均运动速度,取决于工作压力、缸径及负荷。缸径100毫米的气缸,工作压力5巴,空载时活塞平均速度约1米/秒,70％负荷时约为0.45米/秒,因流量饱和及排气背压的影响,提高工作压力并不能进一步提高工作速度,因此空载时的工作速度,是普通气缸所能达到的运动速度的上限。要想进一步提高气动执行元件的工作速度,只有从根本上改变工作原理,采用新型结构。我们对这一课题作了初步的试验研究,参考压紧活塞式冲击气缸的工作原理,把普通气缸的活
Cylinder is the main implementation of pneumatic components, improve the working speed of the implementation of components, is to improve the efficiency of a variety of mechanical production of an important factor. Ordinary cylinder piston average speed of movement, depending on the working pressure, bore and load. Cylinder with 100mm bore, working pressure 5 bar, no load Piston average speed of about 1 m / s, 70% load of about 0.45 m / s, due to flow saturation and exhaust back pressure to improve the working pressure and can not To further improve the working speed, so the working speed of no-load, is the upper limit of the ordinary cylinder can reach the speed of movement. To further improve the speed of the pneumatic actuator, only to fundamentally change the working principle, the use of new structures. We made a preliminary study of this issue, referring to the principle of compacting piston piston cylinder, the ordinary cylinder of the living
