前言:腐蚀性的蒸汽,机械的负载,技术的革新,这一切意味着一个水处理设施运行后没几年,就要对机械和电子设备进行更新。奥地利市政当局选择b&r技术作为水处理设备的控制核心。这个选择带来的效益是:较高的系统可用性,较低的运行成本和满意的操作。
gross-enzersdorf
镇,位于维也纳市郊,自1991年以来,该市的一个水处理工厂持续保持14万人口的处理量。除了1万居民的废水处理,工厂还同时肩负着位于marchfeld的一个大型食品加工厂的污水处理职能,而且,该工厂位于水资源保护区域,所有这些意味着系统必须具有很高的可用性和安全性。
然而,系统在完成后短时间内就开始出现运行问题,在Zui初的几个月内,由于多个供应商之间的协调出现问题导致了系统运行不完善并出现延误。在随后的几年里,随着有害气体的侵入处理导致的电器和机械的故障、磨损的出现(污水中的高泥沙量-marchfeld曾市尼罗河流域的冲积区域)以及不合理的工厂架构,故障出现的频率越来越高。同时,随着先进技术的出现,有些电子或电气的设备已经跟不上技术发展的需要。此外,“随着新的应用标准和条列的出现,对系统的要求也越来越高”,该镇议员hans
jurgen hegendorfer先生这样说道,他曾经是该项目早期的工厂
一个供应商提供整套方案
鉴于当时的情况以及对“千年虫”问题的考虑,议会和相关管理部门在1997年决定改造设备的电气控制系统,“因为在原先的方案中,有多家供应商参与了项目的建设,因此在出现问题的时间常常会出现各家公司相互推卸责任的情况。这就是我们为什么减少供应商数量而将所有的精力集中放到一家公司的原因。”基于这个讨论结果,mts公司Zui终被授权从事对新的控制系统的规划和实施,同时也作为自动化技术维护和支持伙伴。mts是一家专注于电子测量和控制技术领域的设备管理公司,他们与工厂管理阶层一起确定了项目改造的基本宗旨:
●
减少供应商数目
●
减少操作成本
●
增加可靠性
全面的任务分析之后就是实施。mts公司和相关操作人员在b&r
帮助下不间断的逐步更新他们的自动化技术,“我们选择b&r
不单单是因为他们是一个引领产品方向的供应商,同时他们可以基于一个平台提供相关产品,
我们需要一个完整的无故障的现代化的系统。”martin
steiner先生(mts公司总经理和董事)谈到他们的决定时这样说到:“像ethernet
powerlink这样的创新理念技术是我们决策的核心标准,这个现代化的方案使我们通过广域网巧妙地远距离侨接,而避免了重新连接或更换昂贵的线缆
。”但新方案的优点还不仅仅是这些:例如,政府当局贯彻使用b&r的技术的另外一个原因是近期完成的箱式压滤机项目,使经费节约和系统优化的问题都得到了很好的解决。
我们选择b&r,因为它们一家厂商提供了完整的产品线,而这正是我们实现无故障系统改造的必要条件。
箱式压滤机案例:可靠性的提升,经费的削减
解决由设备环境恶化引起的腐蚀性破坏而引起的重复停机问题,是改造控制系统在箱式压滤机也是发酵塔处理整个过程中的要解决的主要问题。
抛弃所有电子机械(急停功能是个例外)的设想对改造任务来讲是个极具挑战性的任务,martin
steiner先生带领的团队采用带ip64保护和集成cpu的b&r power panel
220系列触摸面板很好地完成了任务,位于箱式压滤机电气柜的主控制器—一个15英寸的power
panel面板主要负责控制输入和污水污泥的排放,在控制室内,power
panel面板通过以太网与上一层主站控制器(b&r2005系列)相连。
“除了机械开关的去除,power panel
还大大增加了用户友好性”,martin
sterner先生解释道,只要安全因素允许,控制室的人员与现场操作人员可看到同一个过程图形,而且,因为开关与各种功能都采用软件控制,一些较小的修改都能无故障地快速完成。
每个箱式压滤机在现场均采用10.4英寸power
panel操作,面板集成的cpu同时还控制相应的压滤机,技术员可通过x2x
link技术与每个电气柜中的开关站相连。在开关站,b&r
x20被用作i/o系统,“起初我们并不倾向于使用x20系统,但是当它第一次在手中的时候,我开始改变我的看法”,马丁承认说,“就我本人而言,尽管我与b&r软件接触的时间并不长,但是我已经在很短时间内学会了编程,并且能够在几分钟内完成i/o连接,这就是征服我的根本原因。”mts公司的业务经理从编程者角度进一步讲述了系统亮点:“软件对模块描绘了一个真实的图形,采用显示模块的开关作为虚拟模型系统,用户可以控制每个输入的开或关,而无需在软件中更改特定的值,毫无疑问,这简化了系统的测试工作。”
x20系统确保简单调试
在签定电气柜外包制造合同前,mts的专家们在b&r产品的智能软硬件功能的支持下对整个组装系统进行检查,“电气柜安装于箱式压滤机后,我们所要做的仅仅是连接i/o,Zui后的调试工作便是一项简单快捷的事情。”马丁先生快乐地介绍说。
经营者对于这个结果也非常满意,身为副镇长的hans
juergen
hegendorfer先生肯定地说:“现代化、便捷的设备运行稳定,运行和维护费用大大节省-----一个真正适合我们这个城市的选择。◆
