　　定壓補水裝置產品特點：

　　安全可(ke)靠(kao)：采用(yong)先進的自控系(xi)統，具有雙泵交替(ti)運(yun)行(xing)和事故漏水雙泵同時運(yun)行(xing)功(gong)能，具有低水位保(bao)護(hu)、防(fang)壓力不穩等功(gong)能，可(ke)確保(bao)裝置安全穩定運(yun)行(xing)。

　　使(shi)用壽(shou)命(ming)長：采用不(bu)銹鋼多級泵和特殊設(she)計的進(jin)口穩壓裝置，可(ke)提高機組壽(shou)命(ming)，同時(shi)符(fu)合不(bu)同條(tiao)件下的運行工況

　　安裝方便(bian)：傳(chuan)統(tong)的(de)定壓(ya)補水機組(zu)一(yi)般(ban)散件運輸，現(xian)場安裝，施工難度加(jia)大(da)，設備(bei)的(de)可(ke)靠性差。而穩壓(ya)膨脹(zhang)機組(zu)整機出(chu)廠(chang)，現(xian)場僅需接好進出(chu)水口和電源就可(ke)，簡(jian)單快(kuai)捷。

　　遠(yuan)傳(chuan)控(kong)(kong)制：機組(zu)控(kong)(kong)制柜可與樓宇自控(kong)(kong)系統(tong)連接，遠(yuan)程控(kong)(kong)制補(bu)水泵(beng)的(de)啟停，并通過每(mei)臺(tai)補(bu)水泵(beng)岀(chu)口設置的(de)水流(liu)開關(guan)，檢測補(bu)水泵(beng)的(de)運行狀態。
