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(she)計初始壓(ya)力(li)(li)水頭，采用(yong)保證系統內熱水不(bu)汽化的壓(ya)力(li)(li)作為膨脹水箱內動行終端壓(ya)力(li)(li)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(nang)式(shi)自動給水(shui)(shui)(shui)(shui)(shui)裝置。用于(yu)采暖、空調系(xi)(xi)(xi)統(tong)(tong)中(zhong)(zhong)作為穩壓(ya)(ya)膨脹補水(shui)(shui)(shui)(shui)(shui)設(she)(she)備使(shi)(shi)用，一般稱之為囊(nang)式(shi)落地式(shi)膨脹水(shui)(shui)(shui)(shui)(shui)箱。設(she)(she)備在初(chu)始(shi)運行時(shi)(shi)首(shou)先(xian)啟動補水(shui)(shui)(shui)(shui)(shui)泵向(xiang)系(xi)(xi)(xi)統(tong)(tong)及氣壓(ya)(ya)罐(guan)內的(de)水(shui)(shui)(shui)(shui)(shui)室中(zhong)(zhong)充(chong)水(shui)(shui)(shui)(shui)(shui)，系(xi)(xi)(xi)統(tong)(tong)充(chong)滿后多(duo)余(yu)的(de)水(shui)(shui)(shui)(shui)(shui)被擠進膠囊(nang)內。因為水(shui)(shui)(shui)(shui)(shui)的(de)不(bu)可壓(ya)(ya)縮(suo)性，隨著水(shui)(shui)(shui)(shui)(shui)量的(de)不(bu)斷(duan)(duan)增加，水(shui)(shui)(shui)(shui)(shui)室的(de)體(ti)積也(ye)(ye)不(bu)斷(duan)(duan)的(de)擴(kuo)大而壓(ya)(ya)縮(suo)氣室，罐(guan)內的(de)壓(ya)(ya)力也(ye)(ye)不(bu)斷(duan)(duan)的(de)升高(gao)。當(dang)(dang)壓(ya)(ya)力達到設(she)(she)計(ji)壓(ya)(ya)力時(shi)(shi)，通(tong)過(guo)(guo)壓(ya)(ya)力控制(zhi)器使(shi)(shi)補水(shui)(shui)(shui)(shui)(shui)泵關閉。當(dang)(dang)系(xi)(xi)(xi)統(tong)(tong)內的(de)水(shui)(shui)(shui)(shui)(shui)受(shou)熱(re)膨脹使(shi)(shi)系(xi)(xi)(xi)統(tong)(tong)壓(ya)(ya)力升高(gao)超過(guo)(guo)設(she)(she)計(ji)壓(ya)(ya)力時(shi)(shi)，多(duo)余(yu)的(de)水(shui)(shui)(shui)(shui)(shui)通(tong)過(guo)(guo)安全閥排至補水(shui)(shui)(shui)(shui)(shui)箱循環使(shi)(shi)用，當(dang)(dang)系(xi)(xi)(xi)統(tong)(tong)中(zhong)(zhong)的(de)水(shui)(shui)(shui)(shui)(shui)由于(yu)泄(xie)露或溫(wen)度(du)下(xia)降(jiang)而體(ti)積縮(suo)小，系(xi)(xi)(xi)統(tong)(tong)壓(ya)(ya)力降(jiang)低(di)時(shi)(shi)，膠囊(nang)中(zhong)(zhong)的(de)水(shui)(shui)(shui)(shui)(shui)被不(bu)斷(duan)(duan)壓(ya)(ya)入管網補充(chong)系(xi)(xi)(xi)統(tong)(tong)的(de)壓(ya)(ya)降(jiang)損失(shi)，當(dang)(dang)系(xi)(xi)(xi)統(tong)(tong)壓(ya)(ya)力至設(she)(she)計(ji)允許(xu)的(de)zui低(di)壓(ya)(ya)力時(shi)(shi)，通(tong)過(guo)(guo)壓(ya)(ya)力控制(zhi)器使(shi)(shi)補水(shui)(shui)(shui)(shui)(shui)泵重(zhong)新啟動向(xiang)管網及氣壓(ya)(ya)罐(guan)內補水(shui)(shui)(shui)(shui)(shui)，如(ru)此周而復始(shi)。

　　定壓補水裝置產品特點：

　　安全可靠：采(cai)用(yong)先進的自控系統，具有雙(shuang)泵交替運(yun)行(xing)和事故漏水雙(shuang)泵同(tong)時運(yun)行(xing)功能，具有低水位保(bao)護、防(fang)壓力不(bu)穩等功能，可確保(bao)裝置安全穩定運(yun)行(xing)。

　　使用壽(shou)命長(chang)：采(cai)用不(bu)銹鋼(gang)多級泵(beng)和特殊(shu)設計的進口穩壓裝置，可提高(gao)機組壽(shou)命，同(tong)時符合不(bu)同(tong)條件下(xia)的運行工況

　　安裝方(fang)便：傳統的(de)定壓補水機組(zu)一般散件運輸，現場(chang)安裝，施工(gong)難度加大，設備的(de)可靠性差。而(er)穩壓膨脹機組(zu)整機出廠，現場(chang)僅需接(jie)好進出水口和電源(yuan)就可，簡(jian)單快捷。

　　遠(yuan)傳控制：機組(zu)控制柜(ju)可與樓宇自控系統連接，遠(yuan)程控制補(bu)水(shui)泵的(de)(de)啟停，并通過(guo)每臺補(bu)水(shui)泵岀口設(she)置(zhi)的(de)(de)水(shui)流開關，檢測補(bu)水(shui)泵的(de)(de)運行狀態。
