　　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(wei)囊(nang)式(shi)自(zi)動給水(shui)(shui)(shui)(shui)(shui)裝置。用(yong)于(yu)采(cai)暖、空調系統(tong)(tong)(tong)中作為(wei)穩壓(ya)(ya)膨脹(zhang)補(bu)水(shui)(shui)(shui)(shui)(shui)設(she)(she)備使用(yong)，一般稱之為(wei)囊(nang)式(shi)落地式(shi)膨脹(zhang)水(shui)(shui)(shui)(shui)(shui)箱。設(she)(she)備在初(chu)始(shi)運行時(shi)(shi)(shi)首先啟(qi)動補(bu)水(shui)(shui)(shui)(shui)(shui)泵(beng)(beng)向系統(tong)(tong)(tong)及氣壓(ya)(ya)罐內(nei)的(de)(de)(de)水(shui)(shui)(shui)(shui)(shui)室中充(chong)水(shui)(shui)(shui)(shui)(shui)，系統(tong)(tong)(tong)充(chong)滿后(hou)多余的(de)(de)(de)水(shui)(shui)(shui)(shui)(shui)被(bei)擠進膠(jiao)(jiao)囊(nang)內(nei)。因(yin)為(wei)水(shui)(shui)(shui)(shui)(shui)的(de)(de)(de)不(bu)可壓(ya)(ya)縮性，隨著(zhu)水(shui)(shui)(shui)(shui)(shui)量的(de)(de)(de)不(bu)斷增(zeng)加，水(shui)(shui)(shui)(shui)(shui)室的(de)(de)(de)體積也(ye)不(bu)斷的(de)(de)(de)擴大而壓(ya)(ya)縮氣室，罐內(nei)的(de)(de)(de)壓(ya)(ya)力(li)也(ye)不(bu)斷的(de)(de)(de)升(sheng)高。當(dang)壓(ya)(ya)力(li)達到設(she)(she)計(ji)壓(ya)(ya)力(li)時(shi)(shi)(shi)，通過(guo)壓(ya)(ya)力(li)控制器(qi)使補(bu)水(shui)(shui)(shui)(shui)(shui)泵(beng)(beng)關閉。當(dang)系統(tong)(tong)(tong)內(nei)的(de)(de)(de)水(shui)(shui)(shui)(shui)(shui)受熱膨脹(zhang)使系統(tong)(tong)(tong)壓(ya)(ya)力(li)升(sheng)高超過(guo)設(she)(she)計(ji)壓(ya)(ya)力(li)時(shi)(shi)(shi)，多余的(de)(de)(de)水(shui)(shui)(shui)(shui)(shui)通過(guo)安(an)全(quan)閥排至補(bu)水(shui)(shui)(shui)(shui)(shui)箱循環使用(yong)，當(dang)系統(tong)(tong)(tong)中的(de)(de)(de)水(shui)(shui)(shui)(shui)(shui)由于(yu)泄露或溫(wen)度下降而體積縮小(xiao)，系統(tong)(tong)(tong)壓(ya)(ya)力(li)降低時(shi)(shi)(shi)，膠(jiao)(jiao)囊(nang)中的(de)(de)(de)水(shui)(shui)(shui)(shui)(shui)被(bei)不(bu)斷壓(ya)(ya)入(ru)管網(wang)補(bu)充(chong)系統(tong)(tong)(tong)的(de)(de)(de)壓(ya)(ya)降損(sun)失，當(dang)系統(tong)(tong)(tong)壓(ya)(ya)力(li)至設(she)(she)計(ji)允許的(de)(de)(de)zui低壓(ya)(ya)力(li)時(shi)(shi)(shi)，通過(guo)壓(ya)(ya)力(li)控制器(qi)使補(bu)水(shui)(shui)(shui)(shui)(shui)泵(beng)(beng)重新啟(qi)動向管網(wang)及氣壓(ya)(ya)罐內(nei)補(bu)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(quan)可(ke)靠：采用先進的自控系(xi)統，具有雙泵(beng)交替運(yun)行(xing)和事故漏水(shui)雙泵(beng)同(tong)時運(yun)行(xing)功能，具有低水(shui)位(wei)保護、防壓力不穩等功能，可(ke)確保裝置安全(quan)穩定運(yun)行(xing)。

　　使(shi)用(yong)壽命長：采用(yong)不(bu)銹鋼多級泵和特(te)殊設計的(de)進口穩(wen)壓(ya)裝置，可提高機組(zu)壽命，同時(shi)符合不(bu)同條件下的(de)運行工況

　　安裝方便：傳統的(de)定壓(ya)補水(shui)機組一般散件運(yun)輸，現場安裝，施工(gong)難度加(jia)大(da)，設備的(de)可(ke)靠性差。而穩(wen)壓(ya)膨脹機組整機出廠，現場僅需接好進出水(shui)口和(he)電源就(jiu)可(ke)，簡單(dan)快(kuai)捷。

　　遠傳控(kong)制(zhi)：機組控(kong)制(zhi)柜可(ke)與樓宇自控(kong)系統連(lian)接(jie)，遠程控(kong)制(zhi)補(bu)水泵的啟停(ting)，并通過每(mei)臺補(bu)水泵岀口(kou)設置的水流開關，檢(jian)測補(bu)水泵的運行(xing)狀態。
