摘要

提出了采用回滞函数法控制给水泵最小流量再循环阀的方法。将回滞函数法与工程中常用的单一曲线函数控制方法、PID调节控制方法比较及其实际应用表明

采用回滞函数法控制给水泵最小流量再循环阀的方法防止给水泵汽蚀更为可靠和有效。

Abstract

A method of controlling the recirculatary valve for minimum flow rate of feed-water by using the hysteresis function method has been put forward for preventing occurrence of cavitation in feed-water pumps.The comparison of said method with the commonly used control method in engineering

namely single curve method

and with the PID regulation-controlling method

as well as the practical application show that the method of controlling the recirculatory valve for minimum flow rate of feed-water pumps by using the hysteresis function method is more reliable and effective in prevention of cavitation in feed-water pumps.
