工作原理

目前有三種系列可應用于常見的三類不同的定壓補水方式，帶給設計與用戶更多的選擇：
A系列：變頻定壓補水方式，占地面積很小。
B系列：膨脹罐定壓補水方式，根據系統補水量選擇膨脹罐的容積
C系列：變頻、膨脹罐相結合定壓補水方式
     A系列工作原理：是根據管(guan)網水(shui)(shui)量(liang)變(bian)化自動(dong)(dong)調節一臺(tai)(tai)(tai)水(shui)(shui)泵(beng)(beng)(beng)(beng)轉速(su)(su)和運行(xing)(xing)水(shui)(shui)泵(beng)(beng)(beng)(beng)臺(tai)(tai)(tai)數(shu)，使(shi)水(shui)(shui)泵(beng)(beng)(beng)(beng)出(chu)口(kou)壓(ya)力保(bao)(bao)持(chi)恒(heng)定(ding)，達到適(shi)時(shi)(shi)(shi)補(bu)水(shui)(shui)的目的。當(dang)管(guan)網需(xu)(xu)水(shui)(shui)量(liang)小于(yu)(yu)一臺(tai)(tai)(tai)水(shui)(shui)泵(beng)(beng)(beng)(beng)出(chu)水(shui)(shui)量(liang)時(shi)(shi)(shi)，系統(tong)根據用(yong)(yong)水(shui)(shui)量(liang)變(bian)化有一臺(tai)(tai)(tai)水(shui)(shui)泵(beng)(beng)(beng)(beng)變(bian)頻調速(su)(su)運行(xing)(xing)，當(dang)用(yong)(yong)水(shui)(shui)量(liang)增(zeng)加時(shi)(shi)(shi)管(guan)道系統(tong)內壓(ya)力下(xia)降，這(zhe)時(shi)(shi)(shi)壓(ya)力傳感(gan)器把檢測到的號傳送給(gei)機(ji)控制(zhi)(zhi)單元(yuan)，通過機(ji)運行(xing)(xing)判斷，發出(chu)指令到變(bian)頻器，控制(zhi)(zhi)水(shui)(shui)泵(beng)(beng)(beng)(beng)電(dian)機(ji)，使(shi)轉速(su)(su)加快以保(bao)(bao)證系統(tong)壓(ya)力恒(heng)定(ding)，反之當(dang)用(yong)(yong)水(shui)(shui)量(liang)減少時(shi)(shi)(shi)，使(shi)水(shui)(shui)泵(beng)(beng)(beng)(beng)轉速(su)(su)減慢，以保(bao)(bao)持(chi)恒(heng)壓(ya)。當(dang)用(yong)(yong)水(shui)(shui)量(liang)大(da)于(yu)(yu)一臺(tai)(tai)(tai)泵(beng)(beng)(beng)(beng)出(chu)水(shui)(shui)時(shi)(shi)(shi)， 臺(tai)(tai)(tai)泵(beng)(beng)(beng)(beng)切換到工頻運行(xing)(xing)，第(di)二(er)臺(tai)(tai)(tai)泵(beng)(beng)(beng)(beng)開始變(bian)頻調速(su)(su)運行(xing)(xing)，當(dang)用(yong)(yong)水(shui)(shui)量(liang)小于(yu)(yu)兩臺(tai)(tai)(tai)泵(beng)(beng)(beng)(beng)出(chu)水(shui)(shui)量(liang)時(shi)(shi)(shi)，能自動(dong)(dong)停止一臺(tai)(tai)(tai)或二(er)臺(tai)(tai)(tai)泵(beng)(beng)(beng)(beng)運行(xing)(xing)。在整個運行(xing)(xing)過程中，始終保(bao)(bao)持(chi)系統(tong)恒(heng)壓(ya)不(bu)變(bian)，使(shi)水(shui)(shui)泵(beng)(beng)(beng)(beng)始終工作在區，既(ji)保(bao)(bao)證用(yong)(yong)戶補(bu)水(shui)(shui)要求，又(you)節省電(dian)能。裝置不(bu)需(xu)(xu)配備(bei)專職(zhi)操作人(ren)員。

B系(xi)(xi)列(lie)工作原理：裝置(zhi)設有壓(ya)(ya)(ya)(ya)(ya)(ya)力傳感(gan)(gan)器，當(dang)(dang)系(xi)(xi)統(tong)(tong)壓(ya)(ya)(ya)(ya)(ya)(ya)力降低，與其連接的(de)穩(wen)壓(ya)(ya)(ya)(ya)(ya)(ya)罐(guan)的(de)水(shui)(shui)室壓(ya)(ya)(ya)(ya)(ya)(ya)力也隨(sui)之(zhi)下降，氣室體(ti)積擴張，壓(ya)(ya)(ya)(ya)(ya)(ya)力亦隨(sui)之(zhi)降低，當(dang)(dang)低于設定(ding)(ding)值時(shi)(shi)，壓(ya)(ya)(ya)(ya)(ya)(ya)力傳感(gan)(gan)器把號(hao)傳給(gei)補水(shui)(shui)泵(beng)(beng)(beng)，從而(er)(er)開啟自動補水(shui)(shui)泵(beng)(beng)(beng)，向系(xi)(xi)統(tong)(tong)補水(shui)(shui)，當(dang)(dang)達到(dao)設定(ding)(ding)壓(ya)(ya)(ya)(ya)(ya)(ya)力上限(xian)時(shi)(shi)，壓(ya)(ya)(ya)(ya)(ya)(ya)力傳感(gan)(gan)器又再次把號(hao)傳給(gei)水(shui)(shui)泵(beng)(beng)(beng)，水(shui)(shui)泵(beng)(beng)(beng)自動停止運行，如此周而(er)(er)復始(shi) 。B系(xi)(xi)列(lie)采(cai)用(yong)穩(wen)壓(ya)(ya)(ya)(ya)(ya)(ya)罐(guan)保證(zheng)系(xi)(xi)統(tong)(tong)壓(ya)(ya)(ya)(ya)(ya)(ya)力穩(wen)定(ding)(ding)，防止水(shui)(shui)錘現象的(de)發生，并保證(zheng)給(gei)控制系(xi)(xi)統(tong)(tong)提供一穩(wen)定(ding)(ding)的(de)壓(ya)(ya)(ya)(ya)(ya)(ya)力號(hao)。在系(xi)(xi)統(tong)(tong)壓(ya)(ya)(ya)(ya)(ya)(ya)力超上限(xian)，泄(xie)壓(ya)(ya)(ya)(ya)(ya)(ya)裝置(zhi)自動排水(shui)(shui)泄(xie)壓(ya)(ya)(ya)(ya)(ya)(ya)，保證(zheng)系(xi)(xi)統(tong)(tong)。當(dang)(dang)系(xi)(xi)統(tong)(tong)中水(shui)(shui)受熱(re)，溫度升高(gao)，體(ti)積膨(peng)脹時(shi)(shi)，擠壓(ya)(ya)(ya)(ya)(ya)(ya)氣室，壓(ya)(ya)(ya)(ya)(ya)(ya)力系(xi)(xi)統(tong)(tong)壓(ya)(ya)(ya)(ya)(ya)(ya)力升高(gao)，到(dao)限(xian)定(ding)(ding)值時(shi)(shi)，系(xi)(xi)統(tong)(tong)里的(de)水(shui)(shui)就會通過(guo)泄(xie)壓(ya)(ya)(ya)(ya)(ya)(ya)裝置(zhi)到(dao)膨(peng)脹器（或(huo)軟化水(shui)(shui)箱(xiang)），系(xi)(xi)統(tong)(tong)壓(ya)(ya)(ya)(ya)(ya)(ya)力也隨(sui)之(zhi)下降到(dao)設定(ding)(ding)值，停止泄(xie)壓(ya)(ya)(ya)(ya)(ya)(ya)。 

C系(xi)列工作原理(li)：變頻(pin)與(yu)膨(peng)脹罐定壓補水(shui)方式(shi)相(xiang)結合，使系(xi)統(tong)同時具備A系(xi)列與(yu)A系(xi)列的優點(dian)，達到更節能環(huan)保、運行可靠。
