　　定壓補水裝置產品特點：

　　安全可(ke)靠：采用(yong)先進的(de)自控系統，具有雙泵交替(ti)運(yun)行和事(shi)故(gu)漏(lou)水(shui)(shui)雙泵同時運(yun)行功(gong)能，具有低水(shui)(shui)位(wei)保(bao)(bao)護、防壓(ya)力不穩(wen)等功(gong)能，可(ke)確保(bao)(bao)裝(zhuang)置安全穩(wen)定(ding)運(yun)行。

　　使用(yong)壽(shou)命長(chang)：采用(yong)不銹(xiu)鋼(gang)多(duo)級泵和特殊設計(ji)的進口穩(wen)壓裝(zhuang)置，可提高機組壽(shou)命，同時符合不同條件下的運行工況

　　安裝方便：傳統的定壓補水(shui)機組一(yi)般散件(jian)運輸，現場(chang)安裝，施工(gong)難度加大，設備的可(ke)靠(kao)性差。而(er)穩(wen)壓膨脹(zhang)機組整機出廠，現場(chang)僅需接(jie)好進(jin)出水(shui)口和電(dian)源(yuan)就(jiu)可(ke)，簡(jian)單快(kuai)捷。

　　遠(yuan)傳(chuan)控(kong)(kong)制：機組(zu)控(kong)(kong)制柜可與樓(lou)宇自控(kong)(kong)系統連(lian)接，遠(yuan)程控(kong)(kong)制補水泵的(de)啟停，并通(tong)過每臺補水泵岀(chu)口(kou)設置的(de)水流開(kai)關，檢測補水泵的(de)運行狀態。
