　　定壓補水裝置產品特點：

　　安(an)全可靠：采用先進的自控(kong)系(xi)統，具(ju)有(you)(you)雙(shuang)泵交替運(yun)行和事故漏水(shui)雙(shuang)泵同時運(yun)行功(gong)能，具(ju)有(you)(you)低(di)水(shui)位保護、防壓力(li)不(bu)穩等功(gong)能，可確保裝置安(an)全穩定運(yun)行。

　　使用壽命長：采用不銹鋼多級泵和(he)特(te)殊設計(ji)的進口穩(wen)壓(ya)裝置，可提(ti)高機(ji)組(zu)壽命，同(tong)時符合(he)不同(tong)條件下(xia)的運行工(gong)況

　　安(an)裝方便：傳統的定壓補水(shui)機組(zu)(zu)一般散件運輸，現(xian)場(chang)安(an)裝，施工難(nan)度加(jia)大，設備的可靠性差(cha)。而穩壓膨脹機組(zu)(zu)整(zheng)機出廠，現(xian)場(chang)僅(jin)需接(jie)好進出水(shui)口(kou)和電(dian)源就可，簡單快捷。

　　遠(yuan)傳控(kong)制(zhi)：機組控(kong)制(zhi)柜可與樓(lou)宇自控(kong)系統連(lian)接，遠(yuan)程(cheng)控(kong)制(zhi)補水(shui)泵的(de)啟(qi)停，并通過每臺補水(shui)泵岀口設(she)置的(de)水(shui)流(liu)開關，檢測補水(shui)泵的(de)運行狀態(tai)。
