给水泵液力调速系统的特性及其非线性改善方法分析

Analysis of the Characteristics of a Feedwater Pump Hydraulic Speed Governing System and Its Non-linear Improvement

在对液力偶合器调节给水泵转速系统的调节特性做了分析之后，介绍了用以改善调节特性严重非线性的可变函数发生器的原理及软、硬件设计方法，通过试验分析提出了改进大功率调速型液力偶合器的勺管驱动方法。

After an analysis of the regulating characteristics of the fluid coupling feedwater pump speed regulating system this paper gives a brief account of the principle of a variable function generator used for improving the serious nonlinearity of regulating characteristics and also the software and hardware design method.By way of an experimental analysis a scoop pipe drive method is proposed for the improvement of a high power variable speed fluid coupling.
