气动执行器执行机构的作用形式！

气动执行器执行机构的作用形式！ 主要有两种作用形式，分别是双作用和单作用。 双作用气动执行机构，在压缩空气的作用下，活塞会向两个方向运动。当压缩空气从一端进入时，活塞会向另一端移动；反之，压缩空气从另一端进入，活塞则反向移动。 单作用气动执行机构则有所不同，通常在弹簧的作用下保持在一个初始位置。当压缩空气进入时，克服弹簧力使活塞移动；当压缩空气消失时，弹簧会将活塞推回初始位置。 双作用执行机构输出力较大，适用于需要较大推力和频繁动作的场合；单作用执行机构则在一些需要故障安全位置或推力要求不高的情况下使用。

The functional form of pneumatic actuator actuator!

There are mainly two forms of action, namely dual action and single action.

Double acting pneumatic actuator, under the action of compressed air, the piston will move in two directions. When compressed air enters from one end, the piston will move towards the other end; On the contrary, when compressed air enters from the other end, the piston moves in the opposite direction.

Single acting pneumatic actuators are different and usually remain in an initial position under the action of a spring. When compressed air enters, it overcomes the spring force to move the piston; When the compressed air disappears, the spring will push the piston back to its initial position.

The dual acting actuator has a high output force and is suitable for situations that require significant thrust and frequent movements; Single acting actuators are used in situations where a fail safe position or low thrust requirements are required.
