无负压供水设备

1、无负压供水设备1. 概述：水是人类生命之源，但是，在我国有许多楼房的住户常常备用水难所捆饶。为什么会出现这种情况？ 随着我国城化水平的提高，城市人口急剧增加，居民小区不断建设且楼房层数越来越高，至使原来自来水管网压 力出现缺乏，很多城市普遍存在着用水顶峰期高层楼房上不去水的现象，导致高层居民用水难。目前，一般解决 的方法是修建水池或水箱，通过水泵二次加压供水。这种方法有如下缺点：1. 工程投资大。 建水池，设水箱，工程投资大，施工周期长，占地面积大。2. 存在着水源二次污染。 原本纯洁的自来水都要放入水池中，而水池常常被杂物，脏物等污染物所污染，夏季水池中的水更容易变 质变味 , 严重影响居民

2、的生活和身体健康。为此，许多单位专门装上了消毒设备，无疑，又增加了设备投资 和运行本钱。3. 能源浪费等问题将自来水完全放入水池或水箱，使自来水的压力完全变为零，再从零重新加压，使自来水原有的能量白白浪费掉。我公司研制开发了专利产品 SBH系列无负压管网直联式供水设备，产品推向市场后受到各界关注及广阔用户好评, 现在我公司推出新一代的无负压管网直联式供水设备，它增大了原无负压补偿罐的容积，提高了稳流补偿能力， 使设备更加完善合理，主要优点如下：1. 不用建水池或水箱，与自来水管网直接联接，可充分利用自来水的原有压力。2. 自来水经设备加压后直接供到用户，密封性好，水源不易受污染，供水质量好，是

3、环保型的供水设备。3. 直接同自来水管网相连，充分利用自来水的原有压力，自来水满足要求时，设备就停止工作，节能效果显 著，可到达 50%以上。4. 施工周期短，占地面积小，安装方便，工程总投资可减少60%以上，经济性好。5. 当用户单位停电时，设备可利用自来水管网压力维持局部供水，停电也不停水。6. 设备自动化程度高，具有过流、过热、缺水、缺相等多种保护功能，使用寿命长。SBH型全自动无负压供水设备选型参数表号设怖皿号m'/hvn倾水无自压补宦ar 规格mm规倍mm巾场程 m仍攀Z1SBH-8-30-2-WF63030-70SV40443007520600X1500CR5-64301.
