摘要

结合循环冷却水旋转滤网控制系统改造

介绍了循环水旋转滤网系统的组成及其控制系统的硬件结构、设备选型和控制功能。针对其在安装调试及使用过程中出现的旋转滤网后水位测量值波动问题

分析认为由电噪声干扰引起。经将所有信号电缆更换为屏蔽电缆后

水位测量值稳定

波动消失。

Abstract

The components in rotary strainer system of the circulatory water

as well as the hardware structure

type selection of e- quipment

and control function of the control system have been presented.Directing against the problem concerning measured value fluctuation of the water-level after rotary strainer

which occurred in process of installation

debugging

and application

it is be- lieved from analysis that the flucturation of measured value is resulted from interference of the electric noise

after all the signal cables being replaced by using shielded cables

the fluctuation of water-level has disappeared.
