變(bian)頻恒壓(ya)供(gong)(gong)水(shui)設備廣泛用于企事(shi)業單位、住宅區及農村的生(sheng)產、生(sheng)活、辦公用水(shui)。供(gong)(gong)水(shui)戶(hu)在20－2000戶(hu)。日供(gong)(gong)水(shui)量(liang)在20－50000m3，供(gong)(gong)水(shui)高度(du)達150米，即50層樓房。

設備組成

變頻恒壓(ya)(ya)(ya)供水(shui)設備主要由水(shui)泵機組(zu)、測壓(ya)(ya)(ya)穩壓(ya)(ya)(ya)罐、壓(ya)(ya)(ya)力傳感(gan)器、變頻控制柜(ju)等組(zu)成(cheng)，能始(shi)終維持壓(ya)(ya)(ya)力表壓(ya)(ya)(ya)力（即用戶(hu)管網水(shui)壓(ya)(ya)(ya)）等于用戶(hu)設定值(zhi)。可用于一(yi)般生活或生產供水(shui)。供水(shui)系統(tong)組(zu)成(cheng)方(fang)式(shi)有：

1、變頻供(gong)水設(she)備與市政管網并網恒壓供(gong)水，在供(gong)水壓力可滿(man)足需要(yao)時，自動停運全部水泵。否則，恒壓供(gong)水設(she)備起動，增大壓力滿(man)足用水要(yao)求。

2、附加小泵(beng)(beng)或(huo)(huo)氣壓罐(guan)(guan)，為去除小流量(liang)或(huo)(huo)零流量(liang)供水電耗(hao)，可增加輔助(zhu)(zhu)小泵(beng)(beng)或(huo)(huo)輔助(zhu)(zhu)氣壓罐(guan)(guan)，當供水壓力(li)低時，自動停運主泵(beng)(beng)，使小泵(beng)(beng)或(huo)(huo)氣壓罐(guan)(guan)運行。

3、定制(zhi)變(bian)頻恒壓供(gong)(gong)水(shui)設(she)備可以咨詢杜科泵(beng)(beng)業(ye)。同時提供(gong)(gong)水(shui)泵(beng)(beng)維(wei)修和水(shui)泵(beng)(beng)保(bao)養。

設備功能特點

1、 無負壓

系(xi)統與市政管網(wang)直聯取水(shui)加壓運行(xing)不會造成市政自來水(shui)管網(wang)負(fu)壓。

2、 置壓

通過調(diao)節(jie)許(xu)可(ke)壓(ya)力(li)控制閥(fa)可(ke)設置市政自來水(shui)管網許(xu)可(ke)吸水(shui)壓(ya)力(li)。

3、 借壓（或疊壓）

超過(guo)許可(ke)吸水壓(ya)(ya)力(li)和流量時可(ke)在自來水管網壓(ya)(ya)力(li)基礎上增壓(ya)(ya)。與從普(pu)通蓄水池(chi)吸水相比運行(xing)時可(ke)減少水泵臺數或（和）降(jiang)低轉速(su)達(da)到(dao)節能目的。

變頻恒壓供水設備

4、變頻恒壓

設備實(shi)時通過傳感器檢(jian)測出口(kou)壓力，將(jiang)檢(jian)測值(zhi)和(he)設定(ding)值(zhi)進(jin)行比較運算，確(que)定(ding)電(dian)機(ji)及(ji)水(shui)泵投入臺套數和(he)變(bian)頻(pin)器輸出頻(pin)率（反應到電(dian)機(ji)及(ji)水(shui)泵為轉速）以追貼用水(shui)曲線實(shi)現恒壓。

5、無噪音

采用(yong)(yong)(yong)現代(dai)設計(ji)理念，充分(fen)考慮現代(dai)人(ren)對(dui)環境的要求，選用(yong)(yong)(yong)靜音(yin)專(zhuan)用(yong)(yong)(yong)變頻(pin)器，運用(yong)(yong)(yong)了(le)消音(yin)設計(ji)手(shou)段，故(gu)系統能靜音(yin)運行。

6、停電不斷水

供電(dian)線路停電(dian)時，系(xi)統通過BY PASS等(deng)手段實現停電(dian)不斷水，即停電(dian)時系(xi)統自(zi)動(dong)切換為市政自(zi)來水壓力(li)供水。

7、高度自動化

系統(tong)能實現全自動控制，具(ju)有手動/自動切換、主副泵定時(shi)輪換、壓(ya)力調整(zheng)、恒壓(ya)、高低(di)電(dian)(dian)壓(ya)保(bao)(bao)(bao)護(hu)(hu)、欠相(xiang)保(bao)(bao)(bao)護(hu)(hu)、漏電(dian)(dian)保(bao)(bao)(bao)護(hu)(hu)、過載保(bao)(bao)(bao)護(hu)(hu)、過熱保(bao)(bao)(bao)護(hu)(hu)、缺水保(bao)(bao)(bao)護(hu)(hu)、漏水檢測(ce)補償、不用水停車、瞬間跳閘保(bao)(bao)(bao)護(hu)(hu)等功(gong)能。另可(ke)(ke)根據用戶(hu)需求配(pei)置人(ren)機界面，可(ke)(ke)視化(hua)遠程調整(zheng)、監測(ce)和維護(hu)(hu)。

工作原理

根據用(yong)戶(hu)要求(qiu)，先設定給(gei)水(shui)壓(ya)(ya)力值(zhi)，然后通電(dian)運行(xing)，壓(ya)(ya)力傳感器(qi)(qi)監(jian)測管網(wang)壓(ya)(ya)力，并轉(zhuan)為電(dian)信號送(song)到(dao)(dao)可編(bian)程控(kong)制(zhi)(zhi)器(qi)(qi)或微機控(kong)制(zhi)(zhi)器(qi)(qi)，經分(fen)析處理(li)，將信號傳到(dao)(dao)變頻(pin)器(qi)(qi)來控(kong)制(zhi)(zhi)水(shui)泵(beng)運行(xing)，當(dang)用(yong)水(shui)量增加時，其(qi)輸出的(de)電(dian)壓(ya)(ya)及(ji)頻(pin)率升高(gao)，水(shui)泵(beng)轉(zhuan)數升高(gao)，出水(shui)量增加，當(dang)水(shui)量減(jian)(jian)小(xiao)時，水(shui)泵(beng)轉(zhuan)數降低(di)，減(jian)(jian)少出水(shui)量，使管網(wang)壓(ya)(ya)力維(wei)持設定壓(ya)(ya)力值(zhi)，，在多臺泵(beng)運行(xing)時，逐機軟啟動，由變頻(pin)轉(zhuan)工(gong)頻(pin)到(dao)(dao)壓(ya)(ya)力流量滿足為止，實現(xian)了水(shui)泵(beng)的(de)循環控(kong)制(zhi)(zhi)，當(dang)夜間小(xiao)流量運行(xing)時，可通過變頻(pin)水(shui)泵(beng)來維(wei)持工(gong)作，變頻(pin)給(gei)水(shui)泵(beng)可以停機保壓(ya)(ya)。
