雨水弃流箱电气自动控制系统研究

Study on the Electrical Auto-control System of Initial Rainwater Removal Box

雨水初期弃流是雨水收集利用工程中重要的技术环节,容积型自控式雨水初期弃流装置,适用于要求自动运行、相对准确控制弃流量的雨水收集系统。使用该系统实现了初期雨水与中、后期的分流,有效地提高了回收雨水水质。控制器通过有线控制发出指令,控制延迟器,高水位信号延迟24h,控制电动阀开启,低水位信号关闭电磁阀,使雨水初期弃流装置复位。本文重点介绍延迟器控制原理,延迟时间的实现方式。

The initial rainwater removal is an important teclanical link in the engineering of rainwater collection and utilization, and the cubic auto-control unit is applicable for rainwater collection systems which operated automatically and can control the amount of removal water relatively correct. The paper puts the emphasis on introduction the control principle of delayer and the implementing way of delay time.
