橫峰二次供水設備節能功能傳統的供水方式離不開蓄水池，蓄水池中的水一般由自來水管網供給，這樣，原來有壓力的水進入水池后變成了零壓力，然后再從零壓力開始加壓，造成大量電力靖安的浪費。罐式疊壓無負壓供水設備，是一種理想的節能供水設備，它是一種能直接與自來水管網連接，對自來水管網不會產生任何副作用的二次給水設備，在市政管網壓力的基礎上直接疊壓供水，節約能源，并且還具有全封閉、無污染、占地量小、安裝快捷、運行可靠、維護方便等諸多優點。

橫峰二次供水設備工作原理機械式無負壓供水設備采用微機變頻技術和有效的負壓處理技術實現疊壓供水.具體如下:該設備通過真空補償系統及全封閉結構實現了與自來水管網的直接串接，并且克服了對管網的不良影響。該設備通過管網壓力表、真空抑制器及穩流補償器中的檢測裝置采集穩流補償器內的真空度及水位信號，實時反饋，通過微機控制真空抑制器及穩流補償器中的特殊裝置動作，抑制負壓產生，保證橫峰二次供水設備不對城市管網產生影響。.當市政管網停水時，水泵機組仍可工作，直到穩流補償器中的壓力下降至電接點所設定的下限壓力后自動停機，來水后自動開機。停電時，水泵機組停止工作，自來水可通過直通管路進入用戶管網。來電時機組自動開機恢復正常供水。

橫峰二次供水設備設備主要特點是保護管網壓力、調節峰值用水，節能、安全、環保、供水高品質(解決了二次供水污染)和低噪音。具體的說明如下。1.保證管網壓力，調節峰值用水，水箱入口處采用了智能化的電磁閥來控制進水壓力及水位。當管網壓力下降加壓泵從水箱取水時，可通過智能控制，當水箱水位低于一定液位時，再打開電磁閥從管網中放水，此時保證取水口一定的壓力，此措施一可以避開高峰用水，起調峰作用;二是避免了普通水箱的零壓力泄水，對管網壓力是一個很好的保護作用。2.橫峰二次供水設備運行可靠性：當用水高峰時，或自來水停水時，由水箱供水，大大提高用戶用水的可靠性，完全符合自來水供水規范。3.控制系統先進。建立遠程監控系統，隨時監控設備運轉情況。該系統采用了一款新型的圣博凱斯供水專用供水控制器和相應配套的一體化文本顯示器(HMI)外加GSM通信模塊組成的無線監控文本顯示。該系統使原來控制系統全面開放升級，從原來的獨立單元升級成具有通訊功能的控制系統，文本顯示器與PLC集成一體化，PLC與GSM通信模塊能過RS232通信口連接，實現系統的通訊化，由于GSM通信模塊與現行移動通信網絡接軌，使客戶即使遠離控制現場，只要他身處無線移動通信網絡信號覆蓋的地方，就可時時了解系統信息，利用手機發送命令修改系統功能參數，甚至控制系統運行，真正意義實現了最簡捷便利的系統遠程監控。4.橫峰二次供水設備環保無污染。此成套設備中水箱、水泵、管路及閥門等涉水材料均采用食品級不銹鋼材料，密封供水，不會產生二次污染，衛生環保。5.節能。當自來水壓力能滿足用戶用水要求，增壓泵通過變頻控制處于休眠狀態;當非高峰用水時，自來水壓力又達不到用戶用水壓力，水泵可以在自來水水壓(0.2—0.5MPa)的基礎上疊加增壓，差多少，補多少，充分利用余壓，節約電能。節能效果顯著。
