维控plc在恒压供暖系统的应用
一、简介
供暖系统主要用于北方冬季暖气系统供暖，控制两电机对供暖系统水压控制在恒定范围内，用plc控制减小了工作人员工作量，无需值班人员看守。
二、特点
1、使用维控的PLC，PLC型号为20MT。
2、PLC程序内置算法，通过modbus通讯读取水压值以及变频器当前频率值，当水压不够使plc控制变频器让补水泵开始工作，一定时间内，启动1#补水泵变频启动，变频一定时间即变频达到50hz，水压仍然达不到值，1#补水泵切换到工频，2#变频启动，直到水压保持在设定值内，当水压恒定在设定值内，即1#工频2#变频运行，此时如果变频器频率低于设定的频率运行超过设定时间，将自动切换到1#变频启动状态。2#电机停止运行。
3、系统中还包含无水信号、变频器故障报警信号。水箱中无水信号、变频器故障报警信号送达plc，系统停止工作。
三、组成部分
1、PLC负责动作的直接控制和外界反馈的信息的采集，实现供水系统的自动运作和故障检测。
