1. 项目简介
随着我国物质文明生活水平的提高,高层建筑越来越多,自来水管网压力出现不足,很多城市普遍存在着用水高峰期上不去水的现象。由此引发生活、办公用水难的问题。无负压管网增压设备可直接与自来水管网串接而不产生负压,能够安全、卫生的向用户供水。该设备充分利用了市政自来水管网的原有压力,在原有压力的基础上实现压力叠加,差多少,补多少,使二次加压设备的选型减小,节省投资,同时在使用过程中也可节能很大一笔费用,是目前最先进最新型的二次供水方式。
该设备采用 SIMATIC S7-200 SMART + SMART LINE + V20 变频器。优良的工艺造就了高质量的产品,强大的技术支持保证了产品的高性能。SIMATIC S7-200 SMART 与 SMART LINE 上添加的以太网口,方便了调试程序,不用频繁的插拔电缆,节省了下载程序的时间。V20 变频器的宏指令调用功能,可快速实现参数设置。V20 变频器的小体积与上进下出的接线方式,节省了所占用的空间,便捷的接线方式,强大的功能,简洁的操作方式,体现了基本型变频器的发展趋势。
设备选型为一控二。自动运行时 SIMATIC S7-200 SMART 驱动 V20 变频器。通过变频器拖动一台泵升速,一台泵运行到某个频率能够达到目标压力,则单台泵进行恒压供水。如果单台泵运行到 50Hz,经过延时进行切换,一台工频、一台变频运行,目标压力为用户设定压力。通过触摸屏可以查询以及更改参数。可以查询某一时间段的故障以及故障时间。触摸屏还设计了手动控制系统的启停。
3、 方案确定
由于该无负压供水设备系统属于成熟机的升级,客户比较倾向于性价比高的产品。SIMATIC S7-200 SMART、SMART LINE、V20 作为西门子新一代研产品具有良好的性价比。SIMATIC S7-200 SMART、SMART700IE 本身具有集成的以太网口,既方便了技术人员的调试,又方便了设备连接到工厂的网络上。SIMATIC S7-200 SMART 还有可扩展的 RS485 接口,方便了现场通讯口使用。
a)、设备接通电源,SIMATIC S7-200 SMART 电源信号灯亮,SMART LINE 处于待机工作模式,系统通过 SA1 分为手动与自动模式。
b)、SA1 转换打到自动模式:手动模式是操作人员就地控制每台水泵的启停。手动运行可选择为手动变频或者手动工频。手动变频运行的时,只能运行一台水泵,需要操作人员通过电位器控制频率的升降。
c)、SA1 转换打到自动模式:自动模式又分为屏手动与屏自动。屏手动是操作人员通过 SMART LINE 控制相对应的每台泵的输出。屏自动控制需要操作人员把相关的参数设置完全,系统会判断当前的实际数值与操作员设置的数值进行比较,判断管网压力是小于设定压力还是高于设定压力。
