城市供水解决方案

  • Product Description
  • 1

     

      2012年7月1日起,中国将强制执行最新饮用水标准GB5749-2006《生活饮用水卫生标准》,如果新标准中的106项指标全部达标,自来水就可以直接饮用。新的国标要求对城市供水工艺提出了更高的要求,除工艺水平、管网质量外,各类取水、输水泵、搅拌泵及其他设备稳定可靠的运行也对正常供水、水质起着重要的作用。

      我们为城市供水系统提供系统集控、供配电、电力拖动全方位的解决方案,供您选择:

      1、系统集控

      集中控制系统包括各取水泵站监控系统、水处理系统、管网监控系统等子系统,各子系统互联形成统一的城市供水调度系统。

      1)泵站监控系统

      泵站监控适用于城市泵站的远程监控及管理,由监控中心、通讯平台、泵站远程测控终端、计量测量及摄像设备组成。泵站管理人员可以在泵站管理处的监控中心远程监测站内格栅机的工作状态、污水池水位、提升泵组工作状态、出站流量、池内有害气体浓度等;支持手动、自动、远程控制格栅机、排风机及提升泵的起停。并可实现全站或重要工位的视频监控。

      2)水处理系统

      水处理包括混凝、沉淀、过滤、消毒等工艺流程。原水经取水泵房提升后,添加混凝剂,充分搅拌,形成絮粒后进入沉淀池;在沉淀池中通过重力作用将混凝阶段形成的絮状体分离;经沉淀后,通过过滤去除水中的悬浮颗粒,使水澄清;水经过滤后,通过加药反应进行消毒处理,使水质达到标准要求,然后通过输水泵站送往城市管网。

      水处理系统对上述工艺流程中各提升泵、管路阀门、加药泵等进行自动控制,并实时监控水质、流量、压力等参数,调整控制参数,使整个工艺流程自动可靠运行,确保水质合格。

      3)管网监控系统

      自来水管网监控系统是水司供水调度管理系统的一个子系统,主要由水司调度中心、通信平台、监测终端、压力变送器和流量仪表组成。

      管网监控系统对供水管网测点的压力、流量、流向、水质、各水厂出厂流量、出厂压力、各加压泵、供水泵的工作状态、各储水池水位等进行检测;远程控制各水泵的起停、阀门的开关等;辅助预测、发现爆管事故;提供辅助决策建议。

      系统功能包括:各子系统的流程、过程控制、各类过程参数监控、实时曲线、历史数据曲线、查询、各类报表生成等,并可选配基于互联网的监测、控制功能和基于移动网络的短信报警功能。

      2、智能电网

      1)配电设计及硬件

      我们有丰富的高低压开关柜设计制作经验和丰富的产品线,为客户不同的个性需求提供不同类型的高低压配电系统设计外包服务和产品。高低配电产品包括:KYN、JYN、GG-1A(F)、XGN等系列高压开关柜,GGD、MNS、GCK、GCS、PGL等系列低压配电柜,各种规格低压动力箱、配电箱、仪表控制柜、箱及操作控制台,交直流电源屏、高低压电容补偿等。(备注:上述提到的各类产品链接到对应的产品介绍)

      2)电网集控管理(人机界面)

      电网的人机界面,我们提供丰富的可选测控功能供用户选择,包括:

      a)电网状态、数据集中监测;

      b)电网各开关状态集中控制;

      c)到人的短信状态报警及状态通报功能;

      d)基于互联网的远程抄表、状态监测、控制功能;

      3、电力拖动

      城市供水整个工艺过程中,涉及到大量的取水泵、增压泵、提升泵等水泵。其中,取水泵站、部分提升泵站流量大,使用高压电机拖动较多;水处理过程中的各类取水泵、增压泵、加药泵使用低压电机较多。

      1)高压水泵的拖动

      自来水行业中各水泵一般起动不频繁,采用水电阻、电磁调压、高压固态等软起动设备均能很好的完成起动过程。其中GSDQ水电阻软起动器成本较低,但体积大,维护较麻烦,需定期加水,且不适宜于需要频繁启动的场合;GGQ高压固态软起动器体积小,免维护,可连续多次起动,但由于将电力电子器件直接串接到主回路,因此可靠性相对较低;GDCQ电磁调压软起动器体积适中,免维护,可靠性高,可连续多次起动,适宜于需要高可靠性的场合。根据客户的不同需求,我们为您选择最适合您的起动设备。

      2)低压水泵的起动节能

      各类低压水泵在水处理过程中起着调节流量、确保水处理过程顺利进行的重要作用。我们推荐使用低压变频器对各类水泵电机进行变频控制,一方面节能明显,另一方面可通过变频控制水泵转速来实现流量控制。

      当然,各类低压水泵也可使用DGQ系类软起动器来实现电机的软起动。
