泵和风机偶合器调速控制系统中可编程序控制器的应用

Application of Programmable Controller in the Speed Control System by Fluid Coupling for Pumps and Fans

在泵和风机的液力偶合器调速系统中使用可变函数发生器可以消除因偶合器调节特性的非线性引起的不稳定现象 ,应用可编程序控制器 (PLC)的可变函数发生器可靠性高、操作方便、适用性广。本文就可变函数发生器的PLC实际应用进行了分析介绍 ,同时 。

In speed control system by fluid coupling for pumps and fans,functions generator can avoid unsteady status causing by nonlinearity of regulating characteristics.Functions generator based on PLC has high reliability,broad applicability and easy to operate.This paper make an analysis about how to realized functions generator by PLC,and introduce the method for field debugging.
