主要特點
為解決傳統生活供水系統中,水泵的直接接入自來水管網對自來水管網產生的負壓問題,我公司創新研制開發可新一代WFGW、WFGL系列無負壓變頻給水設備(管網調節增壓設備)。該產品不但解決了地下水池的二次污染問題,還可以和純凈水設備配套,直接作為飲用水的增壓設備,可以在任何一個需要管網增壓的供水系統中使用。
節電節水
采用變頻進行軟件起動,避免了電流沖擊。同時是實現恒壓控制,也避免了對管網的沖擊,延長了管路及閥門的壽命。傳統的水池二次加壓供水方式將自來水放入水池,使原有的自來水壓力釋放為零,浪費可自來水原有壓力能。
該設備利用調節裝置與自來水管網聯結可充分利用管網的壓力能,節電可達50%~90%。
消除了地下水池的二次污染
傳統的水池二次加壓供水方式將自來水放入水池,水池的水易于被贓物甚至動物尸體所污染,尤其在夏天易產生藻類或滋生蚊蟲,直接影響到用戶的身體健康。該設備利用調節裝置采用封閉式供水方式,消除了二次污染。
節省投資,減少占地,安裝、使用、檢修方便
建造水池,工程總投資大,并且使用過程中要定期清洗,不但增加了工程的總投資,還增加了日常的維護費用。該設備利用調節裝置供水,節省投資,減少占地,根據用戶的現場情況可以采用立式或臥式不同的安裝方式,檢修方便。
采用PID閉環調節,恒壓精度高,水壓波動小。
具有過載,短路,過流等各種自動保護功能。
自動化程度高,運行可靠,管理方便。
設計特點和執行標準
WFGW、WFGL系列無負壓變頻給水設備(管網調節增壓設備)是采用優良的設計技術自行開發研制的供水設備。具有變量恒壓,供水壓力精度高的顯著特點,即在壓力不變的前提下,流量從零到更大工作流量范圍內,供水壓力變化范圍在±0.01MPa以內,可消除對自來水管網產生負壓的現象,提高了生活給水系統的可靠性;占地面積小,節省建設投資,安裝使用維護方便;是適合用于工業及民用建筑生活系統的理想給水設備。
WFGW、WFGL系列無負壓變頻給水設備(管網調節增壓設備)主要指標如下:
流量范圍:2.4m3/h-300m3/h;
壓力范圍:0MPa-1.6MPa;(可調)
轉速范圍:0-1450r/min或0-2950r/min;(可調)
工作原理
微機設定給水泵工作壓力,既用戶用水壓力。生活給水時,設備運行在低壓變頻狀態,有變頻器時刻監控管網壓力,對反饋值和設定值進行運算和比較計算,若管網壓力高于用戶所需壓力(設定壓力)則自動減少輸出頻率,從而使泵的轉速減少,出水量減少。若管網壓力低于用戶所需壓力(設定壓力)則自動增加輸出頻率,從而是泵的轉速增加,出水量增加,當一臺泵運行滿足不了用戶需要時,其他各臺泵自動投入,以保證用戶的使用壓力。
當自來水管網的壓力升高到達與用戶使用壓力時候,變頻器經過一段延時后便降低轉速直到停機。只有當壓力降到某一設定壓力值時,變頻器才重新開始工作。變頻泵組的工作知識滿足擁護的用水壓力與管網壓力之差。大大節約了電能。
當流量調節器內壓低于一個大氣壓時,安裝在流量調節器頂的負壓消除器自動打開,使氣體進入流量調節器內,消除負壓。當流量調節器內壓力升高時,又可以將多余的氣體排除流量調節器外,使流量調節器內蓄滿水,以備下次用水高峰期時使用。當流量調節器內蓄滿水后,安裝在流量調節器頂的負壓消除器自動關閉,防止溢流。
工作過程
管網壓力高于或等于用戶壓力時
當自來水壓力高于用戶使用壓力時,旁路止回閥導通,由自來水直接供給用戶用水。用戶壓力高于或等于設定壓力,變頻設備不運行,水泵處于停機狀態。
管網壓力低于用戶壓力時
變頻設備開始運行,水泵處于開始運轉。
管網流量大于等于用戶用水量時
若流量調節器內有空氣則壓力升高,又可以將多余的氣體排出流量調節器外。使流量調節器內蓄滿水以備下次用水高峰期時使用。當流量調節器內蓄滿水后,安裝在流量調節器頂的負壓消除器自動關閉,防止溢流。流量調節器內壓力恢復至自來水管網壓力。
若流量調節器內沒有空氣,流量調節器內壓力保持自來水管網內壓力。
水泵提升壓力為用戶用水壓力與管網里之差。
即水泵提供揚程=用戶用水壓力-管網壓力
管網流量小雨用戶用水量時
流量調節器內壓力降低,當流量調節器內壓力低于一個大氣壓時,安裝在流量調節器頂的負壓消除器自動打開,使氣體進入流量調節器內,消除負壓。
流量調節器內壓力降為零。流量調節器內的水與自來水的流入共同提供給用戶用水。流量調節器內儲備水補償的是用戶用水與管網流量之差。水泵提升壓力為用戶用水壓力。
選型說明
無負壓變頻供水設備的選型是根據用戶自來水管線、壓力與流量,用戶實際用水量、建筑物的高度等數據來確定的,設備表用的調節器容積是按照自來水流量滿足要求 的情況下估算的,如果自來水管路很細,流量不能滿足擁水高峰期的用水要求,需要重新計算調節器的容積,推薦公司如下:
V容積=(Q出-Q進)△t
Q進=作高用水高峰期自來水進水量
Q出=更高用水高峰期用戶用水量
t=更大用水高峰持續時間
適用范圍
化工,制藥,石油,電鍍,食品,電影照相洗印,科研機構,國防
