单作用

The mathematical model of a pneumatic force control system with an asymmetric servovalve and a single-acting cylinder were described.

分析了非对称气动伺服阀控单作用气缸的气动压力控制系统的数学模型。

No—The single-acting cylinder (17) is not good.

不，单作用气缸17不良。

The single-acting cylinder (17) is actuated corresponding to the operation.

单作用气缸17被促动相应到操作。

The single-acting cylinder is moved corresponding to the operation.

单作用气缸移动相应对操作。

Currently, the crank-guide triplex single-acting piston pumps have been difficult to fulfill the requirements of drilling technology.

现用的曲柄连杆式三缸单作用活塞式钻井泵已经很难满足钻井工艺的要求。

Governor, by the force of the spring built-in in the single-acting cylinder (pos. no. 21) and by the reaction of the compressed spring rod.

调速器的杆设定，通过内置在单作用气缸21的弹簧的强力和被压缩的弹簧杆的反作用力。

Upper frame), the output pressure signal of this valve holds the single-acting cylinder pos.

通过操作三通阀22，此阀的输出压力信号保持单作用气缸21在停止位置通过双向止回阀72-1和快速泄放阀41。

This pressure signal actuates the single-acting cylinder pos.

此压力信号促动单作用汽缸17和三通阀29。

The control air which has actuated the single-acting cylinder pos.

动作在单作用气缸17的控制空气通过换向气缸26-Ⅳ上位，和26-Ⅲ上位，放出。

So, the control air which has actuated the single-acting cylinder (pos. no. 21) is blown off rapidly through the quick release valve pos.

因此，施压在单作用气缸21的控制空气被迅速地泄放通过快速泄放阀41。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
