定壓補水裝置設備安全可靠采用系統靜壓作為膨脹水箱內的設計初始(shi)壓(ya)力水頭，采用保(bao)證系統(tong)內熱水不(bu)汽化的壓(ya)力作(zuo)為膨(peng)脹水箱內動行終端壓(ya)力水頭。

　　定壓補水裝置用于生產、消防、生活系統加壓供水，一般稱之為囊式自動(dong)給水(shui)裝置(zhi)。用(yong)(yong)于(yu)采暖、空調系(xi)(xi)統(tong)(tong)(tong)中(zhong)作為穩壓(ya)(ya)(ya)膨脹補(bu)(bu)水(shui)設備使(shi)用(yong)(yong)，一般(ban)稱之(zhi)為囊式落地式膨脹水(shui)箱。設備在初始(shi)運(yun)行時(shi)(shi)首先(xian)啟動(dong)補(bu)(bu)水(shui)泵(beng)(beng)向(xiang)系(xi)(xi)統(tong)(tong)(tong)及(ji)氣(qi)(qi)壓(ya)(ya)(ya)罐內(nei)的(de)(de)水(shui)室中(zhong)充(chong)(chong)水(shui)，系(xi)(xi)統(tong)(tong)(tong)充(chong)(chong)滿后(hou)多余(yu)的(de)(de)水(shui)被擠進膠囊內(nei)。因為水(shui)的(de)(de)不(bu)(bu)可壓(ya)(ya)(ya)縮(suo)性，隨著水(shui)量(liang)的(de)(de)不(bu)(bu)斷(duan)(duan)增加，水(shui)室的(de)(de)體積也不(bu)(bu)斷(duan)(duan)的(de)(de)擴大而壓(ya)(ya)(ya)縮(suo)氣(qi)(qi)室，罐內(nei)的(de)(de)壓(ya)(ya)(ya)力(li)(li)(li)(li)也不(bu)(bu)斷(duan)(duan)的(de)(de)升高。當壓(ya)(ya)(ya)力(li)(li)(li)(li)達到設計(ji)(ji)壓(ya)(ya)(ya)力(li)(li)(li)(li)時(shi)(shi)，通過(guo)(guo)壓(ya)(ya)(ya)力(li)(li)(li)(li)控制(zhi)器使(shi)補(bu)(bu)水(shui)泵(beng)(beng)關(guan)閉(bi)。當系(xi)(xi)統(tong)(tong)(tong)內(nei)的(de)(de)水(shui)受(shou)熱膨脹使(shi)系(xi)(xi)統(tong)(tong)(tong)壓(ya)(ya)(ya)力(li)(li)(li)(li)升高超過(guo)(guo)設計(ji)(ji)壓(ya)(ya)(ya)力(li)(li)(li)(li)時(shi)(shi)，多余(yu)的(de)(de)水(shui)通過(guo)(guo)安全閥排至(zhi)補(bu)(bu)水(shui)箱循(xun)環使(shi)用(yong)(yong)，當系(xi)(xi)統(tong)(tong)(tong)中(zhong)的(de)(de)水(shui)由于(yu)泄露或溫度(du)下(xia)降(jiang)而體積縮(suo)小，系(xi)(xi)統(tong)(tong)(tong)壓(ya)(ya)(ya)力(li)(li)(li)(li)降(jiang)低(di)時(shi)(shi)，膠囊中(zhong)的(de)(de)水(shui)被不(bu)(bu)斷(duan)(duan)壓(ya)(ya)(ya)入管(guan)網補(bu)(bu)充(chong)(chong)系(xi)(xi)統(tong)(tong)(tong)的(de)(de)壓(ya)(ya)(ya)降(jiang)損失，當系(xi)(xi)統(tong)(tong)(tong)壓(ya)(ya)(ya)力(li)(li)(li)(li)至(zhi)設計(ji)(ji)允許的(de)(de)zui低(di)壓(ya)(ya)(ya)力(li)(li)(li)(li)時(shi)(shi)，通過(guo)(guo)壓(ya)(ya)(ya)力(li)(li)(li)(li)控制(zhi)器使(shi)補(bu)(bu)水(shui)泵(beng)(beng)重新啟動(dong)向(xiang)管(guan)網及(ji)氣(qi)(qi)壓(ya)(ya)(ya)罐內(nei)補(bu)(bu)水(shui)，如此(ci)周而復始(shi)。

　　定壓補水裝置產品特點：

　　安全可靠：采用先進的自控系統，具(ju)有雙泵交替運(yun)(yun)行和(he)事故漏水(shui)雙泵同時運(yun)(yun)行功能，具(ju)有低水(shui)位保(bao)(bao)護、防壓力(li)不穩等功能，可確保(bao)(bao)裝置(zhi)安全穩定運(yun)(yun)行。

　　使用壽命長：采用不(bu)銹鋼(gang)多(duo)級泵和特殊設計的進(jin)口穩壓裝置，可(ke)提(ti)高機組壽命，同(tong)時符合不(bu)同(tong)條件下的運行工況

　　安裝方便：傳統(tong)的定壓補水(shui)機(ji)(ji)組(zu)一(yi)般散(san)件運輸，現(xian)場(chang)安裝，施工(gong)難(nan)度加大，設備的可靠性差(cha)。而穩壓膨脹(zhang)機(ji)(ji)組(zu)整機(ji)(ji)出廠，現(xian)場(chang)僅需(xu)接(jie)好進出水(shui)口和電源就可，簡(jian)單快捷。

　　遠傳控制(zhi)：機(ji)組控制(zhi)柜可(ke)與樓宇自控系統連接(jie)，遠程(cheng)控制(zhi)補水泵(beng)的啟停(ting)，并通過每臺補水泵(beng)岀口設置的水流開關，檢測補水泵(beng)的運行(xing)狀態(tai)。
