一、張掖恒壓供水設(shè)備概述
隨著我國社會主義現(xiàn)代化建設(shè)事業(yè)的持續(xù)發(fā)展,給排水設(shè)備也在不斷提高,從過去老式的水泵加屋頂水箱到現(xiàn)在變頻供水(節(jié)能、去掉了易污染的屋頂水池)。近年來又一新型的供水設(shè)備出現(xiàn)——無負壓變頻恒壓供水,它是在變頻恒壓供水設(shè)備上發(fā)展起來的,它主要由無負壓調(diào)節(jié)罐、水泵、氣壓罐、智能控制系統(tǒng)等組成。就它的工作原理介紹如下:
Today, as the school was holding the sport meeting, I will have three days off, so I decided to have fun with my friends, we went to the small old town which is near my school. Early in the morning, we took the bus, after three hours, we arrive at the place. The town is so primitive, all the buildings conserve their original faces, which makes them popular among the modernized world. Many people like to go to there to have a vacation, because they can feel the peace, they want to calm themselves down in the busy work, finding a peaceful land and take a think about their lives. I like that town so much, I feel I am part of the town, the scenery is so attractive and the tradition there is so special. I hope this town will not change, just keep what it is.
二、張掖恒壓供水設(shè)備設(shè)備特點
1、張掖恒壓供水設(shè)備節(jié)電節(jié)水
采用變頻進行軟件起動,避免了電流沖擊。同時是實現(xiàn)恒壓控制,也避免了對管網(wǎng)的沖擊,延長了管路及閥門的壽命。傳統(tǒng)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(shè)備利用調(diào)節(jié)裝置與自來水管網(wǎng)聯(lián)結(jié)可充分利用管網(wǎng)的壓力能,節(jié)電可達50%~90%。
2、張掖恒壓供水設(shè)備消除了地下水池的二次污染
傳統(tǒng)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(chǎn)生藻類或滋生蚊蟲,直接影響到用戶的身體健康。該設(shè)備利用調(diào)節(jié)裝置采用封閉式供水方式,消除了二次污染。
3、張掖恒壓供水設(shè)備節(jié)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(shè)備利用調(diào)節(jié)裝置供水,節(jié)省投資,減少占地,根據(jù)用戶的現(xiàn)場情況可以采用立式或臥式不同的安裝方式,檢修方便。
4、采用PID閉環(huán)調(diào)節(jié),恒壓精度高,水壓波動小。
5、具有過載,短路,過流等各種自動保護功能。
6、自動化程度高,運行可靠,管理方便。
Today, as the school was holding the sport meeting, I will have three days off, so I decided to have fun with my friends, we went to the small old town which is near my school. Early in the morning, we took the bus, after three hours, we arrive at the place. The town is so primitive, all the buildings conserve their original faces, which makes them popular among the modernized world. Many people like to go to there to have a vacation, because they can feel the peace, they want to calm themselves down in the busy work, finding a peaceful land and take a think about their lives. I like that town so much, I feel I am part of the town, the scenery is so attractive and the tradition there is so special. I hope this town will not change, just keep what it is.
三、自來水管網(wǎng)的水直接進入調(diào)節(jié)罐,罐內(nèi)的空氣從真空消除器內(nèi)排出,待水充滿后,真空消除器自動關(guān)閉。當(dāng)自來水能夠滿足用水壓力及水量要求時,設(shè)備通過旁通止回閥向用水管網(wǎng)直接供水;當(dāng)自來水管網(wǎng)的壓力不能滿足用水要求時,系統(tǒng)通過壓力傳感器(或壓力控制器、電接點壓表)給出起泵信號起動水泵運行。水泵供水時,若自來水管網(wǎng)的水量大于水泵流量,系統(tǒng)保持正常供水;用水高峰期時,若自來水管網(wǎng)水量小于水泵流量時,調(diào)節(jié)罐內(nèi)的水作為補充水源仍能正常供水,此時,空氣由真空消除器進入調(diào)節(jié)罐,消除了自來水管網(wǎng)的負壓,用水高峰期過后,系統(tǒng)恢復(fù)正常的狀態(tài)。若自來水管網(wǎng)停水而導(dǎo)致調(diào)節(jié)罐內(nèi)的水位不斷下降,液位探測器給出水泵停機信號以保護水泵機組。
四、張掖恒壓供水設(shè)備的應(yīng)用與缺陷
無負壓變頻供水本身是一種供水設(shè)備,根據(jù)它自身的特點應(yīng)用如下:
1、張掖恒壓供水設(shè)備適用于任何自來水壓力不足地區(qū)的加壓給水。
2、張掖恒壓供水設(shè)備新建改建擴建的住宅小區(qū)、寫字樓、綜合樓生
活用水。
3、張掖恒壓供水設(shè)備自來水廠的給水中間加壓泵站。

Today, as the school was holding the sport meeting, I will have three days off, so I decided to have fun with my friends, we went to the small old town which is near my school. Early in the morning, we took the bus, after three hours, we arrive at the place. The town is so primitive, all the buildings conserve their original faces, which makes them popular among the modernized world. Many people like to go to there to have a vacation, because they can feel the peace, they want to calm themselves down in the busy work, finding a peaceful land and take a think about their lives. I like that town so much, I feel I am part of the town, the scenery is so attractive and the tradition there is so special. I hope this town will not change, just keep what it is.
盡管無負壓變頻供水設(shè)備有它自身的優(yōu)點(節(jié)能、衛(wèi)生等)但有它明顯不足的一面。首先,它的供水可靠性不高。由于它缺少畜水池,市政供水一有故障,整個設(shè)備癱瘓,用戶沒水用。因此對用水要求高的建筑物和消防用水是不適應(yīng)。其次,由于它一種新型的設(shè)備,技術(shù)不是很成熟,技術(shù)參數(shù)并不很規(guī)范,如選型水泵(H、Q),調(diào)節(jié)罐(V)的確定等等。第三,由于它是從市政管網(wǎng)中直接抽水,盡管可以解決負壓問題,但還得取得主管部門批準。(《城市供水條例》規(guī)定:禁止在城市公共管道上直接裝泵抽水)zui后是該設(shè)備技術(shù)還有待進一步完善。如技術(shù)應(yīng)用的前提是什么?城市給水管供水量與二次供水用戶zui大用水量的匹配關(guān)系;無負壓變頻供水設(shè)計流量如何取值,泵要否備用;穩(wěn)流罐起何作用?是密閉的嗎?容積如何取值;如何保證空氣不污染二次供水水質(zhì)? 還有待大家共同去探討。
總之,一種新的產(chǎn)品不可能解決所有問題,能解決一些問題就是一種進步,我們應(yīng)該去支持它,發(fā)展它。
五、張掖恒壓供水設(shè)備
為解決傳統(tǒng)生活供水系統(tǒng)中,水泵的直接接入自來水管網(wǎng)對自來水管網(wǎng)產(chǎn)生的負壓問題,我公司創(chuàng)新研制開發(fā)可新一代CDL4-12系列無負壓給水設(shè)備(管網(wǎng)調(diào)節(jié)增壓設(shè)備)。該產(chǎn)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(shè)備配套,直接作為飲用水的增壓設(shè)備,可以在任何一個需要管網(wǎng)增壓的供水系統(tǒng)中使用。該系列產(chǎn)品獲得多項使用新型國家。
六、張掖恒壓供水設(shè)備工作原理
微機設(shè)定給水泵工作壓力,既用戶用水壓力。生活給水時,設(shè)備運行在低壓變頻狀態(tài),有變頻器時刻監(jiān)控管網(wǎng)壓力,對反饋值和設(shè)定值進行運算和比較計算,若管網(wǎng)壓力高于用戶所需壓力(設(shè)定壓力)則自動減少輸出頻率,從而使泵的轉(zhuǎn)速減少,出水量減少。若管網(wǎng)壓力低于用戶所需壓力(設(shè)定壓力)則自動增加輸出頻率,從而是泵的轉(zhuǎn)速增加,出水量增加,當(dāng)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(dāng)自來水管網(wǎng)的壓力升高到達與用戶使用壓力時候,變頻器經(jīng)過一段延時后便降低轉(zhuǎn)速直到停機。只有當(dāng)壓力降到某一設(shè)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(wǎng)壓力之差。大大節(jié)約了電能。
當(dāng)流量調(diào)節(jié)器內(nèi)壓低于一個大氣壓時,安裝在流量調(diào)節(jié)器頂?shù)呢搲合髯詣哟蜷_,使氣體進入流量調(diào)節(jié)器內(nèi),消除負壓。當(dāng)流量調(diào)節(jié)器內(nèi)壓力升高時,又可以將多余的氣體排除流量調(diào)節(jié)器外,使流量調(diào)節(jié)器內(nèi)蓄滿水,以備下次用水高峰期時使用。當(dāng)流量調(diào)節(jié)器內(nèi)蓄滿水后,安裝在流量調(diào)節(jié)器頂?shù)呢搲合髯詣雨P(guān)閉,防止溢流。
七、張掖恒壓供水設(shè)備工作過程
1、管網(wǎng)壓力高于或等于用戶壓力時
當(dāng)自來水壓力高于用戶使用壓力時,旁路止回閥導(dǎo)通,由自來水直接供給用戶用水。用戶壓力高于或等于設(shè)定壓力,變頻設(shè)備不運行,水泵處于停機狀態(tài)。
2、管網(wǎng)壓力低于用戶壓力時
變頻設(shè)備開始運行,水泵處于開始運轉(zhuǎn)。
3、管網(wǎng)流量大于等于用戶用水量時
若流量調(diào)節(jié)器內(nèi)有空氣則壓力升高,又可以將多余的氣體排出流量調(diào)節(jié)器外。使流量調(diào)節(jié)器內(nèi)蓄滿水以備下次用水高峰期時使用。當(dāng)流量調(diào)節(jié)器內(nèi)蓄滿水后,安裝在流量調(diào)節(jié)器頂?shù)呢搲合髯詣雨P(guān)閉,防止溢流。流量調(diào)節(jié)器內(nèi)壓力恢復(fù)至自來水管網(wǎng)壓力。
若流量調(diào)節(jié)器內(nèi)沒有空氣,流量調(diào)節(jié)器內(nèi)壓力保持自來水管網(wǎng)內(nèi)壓力。
水泵提升壓力為用戶用水壓力與管網(wǎng)里之差。
即水泵提供揚程=用戶用水壓力-管網(wǎng)壓力
管網(wǎng)流量小雨用戶用水量時流量調(diào)節(jié)器內(nèi)壓力降低,當(dāng)流量調(diào)節(jié)器內(nèi)壓力低于一個大氣壓時,安裝在流量調(diào)節(jié)器頂?shù)呢搲合髯詣哟蜷_,使氣體進入流量調(diào)節(jié)器內(nèi),消除負壓。
流量調(diào)節(jié)器內(nèi)壓力降為零。流量調(diào)節(jié)器內(nèi)的水與自來水的流入共同提供給用戶用水。流量調(diào)節(jié)器內(nèi)儲備水補償?shù)氖怯脩粲盟c管網(wǎng)流量之差。水泵提升壓力為用戶用水壓力。
真空消除器
真空消除器它是本設(shè)備的核心,依靠它消除管網(wǎng)中負壓,從而不影響周圍用水,保護管網(wǎng)與設(shè)備,達到市政供水的要求。它的工作原理比較簡單,跟一個復(fù)合排氣閥如出一轍。它主要由一個浮球來工作的,根據(jù)無負壓調(diào)節(jié)罐罐內(nèi)水位的升降帶動浮球的垂直上下移動控制閥門的開和關(guān),從而達到調(diào)節(jié)罐吸氣和排氣,同時實現(xiàn)了罐內(nèi)真空(罐內(nèi)水未滿的時候)的消除。真空消除器是一個新名詞,所以很多廠家在它的身上大做文章,做得有一點的神秘(包裝得很好)。 其實它只是一個能自動進出空氣的閥門,而且造價也不高。

Today, as the school was holding the sport meeting, I will have three days off, so I decided to have fun with my friends, we went to the small old town which is near my school. Early in the morning, we took the bus, after three hours, we arrive at the place. The town is so primitive, all the buildings conserve their original faces, which makes them popular among the modernized world. Many people like to go to there to have a vacation, because they can feel the peace, they want to calm themselves down in the busy work, finding a peaceful land and take a think about their lives. I like that town so much, I feel I am part of the town, the scenery is so attractive and the tradition there is so special. I hope this town will not change, just keep what it is.
