WOODWARD 5461-777卡件PLC自动化模块现货

换热站主要由热交换器、循环泵组、补水泵组、传感仪表、调节阀门、PLC控制柜等组成。

换热站工作原理：一级管网供水由其自身的压力进入机组的换热器，进行热交换后返回热电厂或锅炉房。二级管网回水经过过滤后，经循环泵进入换热器，被蒸汽或高温水加热后向用户提供所需热水。补水泵将软换水打入系统以补充系统运行损失的水量，并通过变频调速保持系统压力的稳定。
CTSC-200系列PLC自动控制系统主要完成以下功能：
1、一级管网供水、一级管网回水的温度、压力、流量的测量；
2、二级管网供水、二级管网回水的温度、压力、流量的测量；
3、通过控制一级管网供水的流量，保证二级管网供水温度恒定或者回水温差恒定；
4、通过变频控制循环泵和补水泵，保证二级管网供水压力恒定或者回水压差恒定；

三、总结
1、采用深圳合信CTSC-200系列PLC实现了换热站系统的自动运行，充分发挥变频器的调速和节能的优点。an operator station is required to be provided when the equipment is runningThe operator performs manual operation. When the wire rod falls continuously from the roller table, the wire rod falls into the closed steel receiving claw through the nose cone. If the mandrel rotates in place, the nose cone rises and the steel receiving claw opens. All the wires that have fallen into the steel receiving claw pass through the mandrel and fall into the steel receiving support plate that has risen in place. With the subsequent wire rod falling in slowly, the steel receiving carriage drops slowly driven by the frequency converter until three complete finished wires have been stored on the steel receiving plate, When the steel connecting carriage is also lowered to the lower limit, the steel connecting claw is closed, the nose cone falls, and the steel connecting carriage is opened. At this time, the mandrel a and the finished wire rod rotate in the positive direction to the packaging position, the mandrel B rotates
