摘要
介绍了谏壁抽水站闸门液压启闭机控制系统的工作原理以及改造前存在的主要问题,通过采用可编程序控制器替代原传统继电器与按钮相结合的控制方式、将闸门开度传感装置由钢丝绳重锤码盘式改为橡胶轮码盘式、直流操作电源系统采用交直流双电源供电、增设功能开关等形式,对闸门液压启闭机电气控制系统进行了改造;结合运行管理中的经验,从设计、施工、运用等多方面进行改进和完善,使闸门液压启闭机电气控制系统达到了操作简单、运行可靠、便于调试设定和运行维护的要求,实现了闸门自动化控制的目的。
The working principles and the main problems of hydraulic start and stop electric control system in Jianbi pump station gate were introduced, and some feature were presented also, such as control controller instead of traditional relay combined with button, gate opening sensor using rubber weighted encoder disk instead of wire rope encoder disk, direct current operational power supply by universal motor, and function switch adopted, which modified the control system. And based on the experience, design, construct, and operation were improved, which make operation simply and run reliable.
