產品概述
無負壓智能供水設備，也常叫疊壓供水設備、罐式無負壓供水設備，是目前高層住宅、小區二次供水最主流的智能加壓設備。它直接串接在市政自來水管網上，在不產生負壓、不影響周邊用戶用水的前提下，利用市政原有壓力疊加增壓，實現恒壓、穩定、節能供水。
技術參數
1、流量范圍：≤1000m3/h
2、壓力范圍：≤2.0MPa
3、控制單臺水泵功率：<315kW
4、壓力調節精度：<±0.01MPa
5、環境溫度：0~+40℃
6、相對濕度：≤90%(電控部分)
7、電源：380*(1+10%)50HZ±2Hz
8、防護等級：控制柜(IP30)、水泵(IP54)
系統工作原理
(1)當市政管網本身滿足供水要求時，設備處于停機狀態，市政水源通過旁通管路或流經水泵直接向用戶管網供水。
(2)當市政管網欠壓(需增壓供水)時，設備自動啟動，在市政原有水壓基礎上變頻調速接力增壓供水，由于按“差多少，補多少”的原則增壓，在供水流量范圍內滿足用戶恒壓供水的需求，同時又實現了高效節能運行。
(3)設備的控制系統本身即可設置為連續運行方式(不停機),也可現場設置為間歇運行(自動起停)方式，設備如需間歇運行，應在設備選型時配套選購一臺氣壓罐。夜間小流量供水且自來水管網壓力不能滿足要求時，氣壓罐可以貯存并釋放能量，避免了水泵頻繁啟動。
(4)為防止過度抽吸，設備具有低壓禁止運行功能，即當市政水源壓力太低(不允許繼續抽吸)時，經延時確認設備會自動停機。
