实验室导叶数字控制装置

本文介绍了用于水力机械传动模试验的导叶数字控制装置，它由步进电机，步进电机控制器，步液马达，液压柜等组成。文中详细介绍了数字电路中的脉冲分配器，环形多谐振荡器的工作原理。该装置能方便地实现导叶的两段直线关闭规律，并能灵活地调节两段直线关闭规律的关闭速度和关闭时间，为在实验室研究导叶的最佳关闭规律提供了一个有效的试验手段。

The Guide Vane Numerical Control Devicein the Laboratory

Abstract The guide vane numerical control device used at the dynamic analogue experiment of the hydraulic machinary is introduced in this paper. It is consists of a step motor, a step motor controller, a step-liquid motor, a pressure tank . The working principle of the impulse distributor and the circle multiple-harmonic oscillator in the numerical circuit are introduced in detail. This device may be used at realizing the guide vane two step closing law of a straight line, and flexibly regulate the c'osing speed and time. A effective experiment device to research the optimum closing law of the guide vane in the laboratory is provided.
