如何進(jìn)行水處理

衡美水處理為您介紹一種經(jīng)久耐用、性能優(yōu)越的水處理設(shè)備——供水設(shè)備,并為您對其作用做具體分析

供水設(shè)備


八、無負(fù)壓供水設(shè)備

1、產(chǎn)品

傳統(tǒng)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(wǎng)供給,這樣原來有壓力的水進(jìn)入水池后變成了零壓力,然后再從零壓力開始加壓,造成大量電力資源的浪費(fèi)。

罐式疊壓無負(fù)壓供水設(shè)備,是一種理想的節(jié)能供水設(shè)備,它是一種能直接與自來水管網(wǎng)連接,對自來水管網(wǎng)不會產(chǎn)生任何副作用的二次給水設(shè)備,在市政管網(wǎng)壓力的基礎(chǔ)上直接疊壓供水,節(jié)約能源,并且還具有全封閉、占地量小、安裝快捷、運(yùn)行可靠、維護(hù)方便等諸多優(yōu)點(diǎn)

2、設(shè)備原理

全自動智能無負(fù)壓變頻供水設(shè)備,是通過穩(wěn)流罐和自來水管網(wǎng)直接連接,按設(shè)定方式直接二次加壓供水并且不會對自來水管網(wǎng)產(chǎn)生負(fù)壓的設(shè)備。主要有由水泵機(jī)組、無負(fù)壓穩(wěn)流罐、變頻供水控制柜、閥門、儀表、管路、設(shè)備底座等組成。

罐式無負(fù)壓供水設(shè)備正常投入使用時,市政管網(wǎng)的水進(jìn)入無負(fù)壓穩(wěn)流罐,罐內(nèi)的空氣從排氣閥大量排出,當(dāng)空氣排完時閥內(nèi)浮球被水浮起,傳動塞頭至關(guān)閉位置,慢慢關(guān)閉排氣口,停止排氣,防止出水當(dāng)穩(wěn)流罐內(nèi)水流正常輸送時,如有少量空氣聚集在罐內(nèi)到相當(dāng)程度,罐內(nèi)水位下降,浮球隨之下降,此時空氣則有排氣孔排出。

設(shè)備正常運(yùn)行過程中,當(dāng)市政管網(wǎng)供水量不足時,市政進(jìn)水管管內(nèi)水流空時,或穩(wěn)流罐內(nèi)水壓低于大氣壓時,穩(wěn)流罐內(nèi)水位下降,浮球隨之下降,帶動塞頭開啟,吸入空氣,使穩(wěn)流罐內(nèi)保持大氣壓力,不對市政管網(wǎng)產(chǎn)生負(fù)壓。

當(dāng)市政管網(wǎng)中壓力低于用戶所需的設(shè)定壓力時,水泵變頻調(diào)速運(yùn)行,保證用戶管網(wǎng)壓力符合用戶用水的要求。市政管網(wǎng)水壓越高,水泵的轉(zhuǎn)速越低,市政管網(wǎng)水壓越低,水泵的轉(zhuǎn)速越高。當(dāng)市政管網(wǎng)供水壓力達(dá)到用戶要求時,設(shè)備自動停止工作,市政管網(wǎng)的水通過旁通管直接供給用戶使用。

當(dāng)市政管網(wǎng)停水時,穩(wěn)流罐內(nèi)的水位逐漸下降,當(dāng)降至下限,穩(wěn)流罐上的液位計發(fā)出停機(jī)信號,設(shè)備自動停止運(yùn)行并顯示缺水保護(hù)信號。

當(dāng)電網(wǎng)停電時設(shè)備停機(jī),市政管網(wǎng)的水直接從設(shè)備旁通管供應(yīng)到用戶。

3、產(chǎn)品特點(diǎn)

1節(jié)省投資

無需修建蓄水池或屋頂水箱,采用疊壓供水,減小設(shè)備初期投入。因此,與普通無塔供水設(shè)備相比,可節(jié)省一半左右的投資。

2)有效節(jié)能,運(yùn)行成本低

傳統(tǒng)的供水系統(tǒng)先把自來水管原有的水儲存在水池水箱中,原有的自來水壓力全部釋放為零,然后從零開始加壓,使原有的能源白白的浪費(fèi)掉。據(jù)“供水設(shè)備推廣部門”顯示,無塔供水設(shè)備可充分利用市政管網(wǎng)供水壓力,差多少、補(bǔ)多少、不產(chǎn)生負(fù)壓、與傳統(tǒng)供水設(shè)備相比可節(jié)能百分之九十。停電也可維持市政管網(wǎng)水壓供水。

3智能化程度高,操作簡單,節(jié)省人力

該設(shè)備由全自動智能化控制器控制,自行根據(jù)用戶的用水量和管網(wǎng)的自來水壓力進(jìn)行調(diào)節(jié),實(shí)行無人值守。并且采用人機(jī)界面(文本、數(shù)字)顯示,使客戶更加直觀的看到設(shè)備的運(yùn)行狀況。

4環(huán)保衛(wèi)生

設(shè)備全封閉運(yùn)行,消除水源二次污染

5保護(hù)功能齊全

具有完的過載、短路、過壓、欠壓、缺相、過流、水源缺水等自動保護(hù)功能。在異常情況下能進(jìn)行信號報警、自檢、故障判斷等。

6占地少安裝方便

整套設(shè)備只有一組供水控制柜、無負(fù)壓穩(wěn)流罐和水泵機(jī)組三部分,安裝非常簡單方便。

7延長設(shè)備的使用壽命

對多臺泵組均能可靠的實(shí)現(xiàn)軟啟動,使電網(wǎng)和管網(wǎng)免沖擊,延長了水泵及電機(jī)的使用壽命。

九、變頻無塔供水設(shè)備

1、產(chǎn)品概述

變頻無塔供水設(shè)備是將交流變頻調(diào)速技術(shù)和微機(jī)控制技術(shù)應(yīng)用于水泵自動控制設(shè)備之中,并與水泵機(jī)組相結(jié)合的機(jī)電一體化供水裝置。其核心設(shè)備交流變頻調(diào)速控制柜融合了微機(jī)控制變頻調(diào)速技術(shù),微機(jī)控制PID調(diào)節(jié)技術(shù)和微機(jī)可編程控制器等技術(shù)。 本設(shè)備依據(jù)供水管網(wǎng)中瞬時變化的壓力和流量參數(shù),自動改變水泵的臺數(shù)和運(yùn)行轉(zhuǎn)速,實(shí)現(xiàn)恒壓變量供水的閉環(huán)調(diào)節(jié),從而達(dá)到提高供水質(zhì)量和節(jié)能的目的。

2、設(shè)備原理

變頻供水設(shè)備的基本工作原理是根據(jù)用戶用水量變化自動調(diào)節(jié)運(yùn)行水泵臺數(shù)和一臺水泵轉(zhuǎn)速,使水泵出口壓力保持恒定。當(dāng)用戶用水量小于一臺水泵出水量時,系統(tǒng)根據(jù)用水量變化有一臺水泵變頻調(diào)速運(yùn)行,當(dāng)用水量增加時管道系統(tǒng)內(nèi)壓力下降,這時壓力傳感器把檢測到的信號傳送給微機(jī)控制單元,通過微機(jī)運(yùn)行判斷,發(fā)出指令到變頻器,控制水泵電機(jī),使轉(zhuǎn)速加快以保證系統(tǒng)壓力恒定反之當(dāng)用水量減少時,使水泵轉(zhuǎn)速減慢,以保持恒壓。當(dāng)用水量大于一臺泵出水時,泵切換到工頻運(yùn)行,下一臺泵開始變頻調(diào)速運(yùn)行,當(dāng)用水量小于兩臺泵出水量時,能自動停止一臺或臺泵運(yùn)行。在整個運(yùn)行過程中,始終保持系統(tǒng)恒壓不變,使水泵始終工作,既保證用戶恒壓供水,又節(jié)省電能。設(shè)備不需配備專職操作人員。

3、產(chǎn)品特點(diǎn)

1經(jīng)濟(jì)效益顯著

使用該設(shè)備,可不建造水塔、不設(shè)樓頂水箱,既減少工程施工周期,又解決了工程造價費(fèi)用高的缺點(diǎn),還克服了氣壓波動大,水泵啟動頻繁等不足之處。

4節(jié)能

該設(shè)備能根據(jù)用戶用水量的變化來調(diào)節(jié)水泵轉(zhuǎn)速,使水泵始終工作,節(jié)電效果明顯,較恒速水泵大為節(jié)電

5操作簡單

該設(shè)備采用全自動控制,PID調(diào)節(jié),鍵盤操作,人機(jī)界面(文本、數(shù)字)顯示。操作人員只需轉(zhuǎn)換電控柜開關(guān),就可以實(shí)現(xiàn)用戶所需工況,實(shí)現(xiàn)全自動無人值守。

6 保護(hù)功能齊全

具有完善的過載、短路、過壓、欠壓、缺相、過流、短路、水源缺水等自動保護(hù)功能。在異常情況下能進(jìn)行信號報警、自檢、故障判斷等。

7占地少安裝方便

整套設(shè)備只有一組供水控制柜和水泵機(jī)組,安裝非常簡單方便。

8延長水泵及電機(jī)的使用壽命

對多臺泵組均能可靠的實(shí)現(xiàn)軟啟動,使電網(wǎng)和管網(wǎng)免沖擊,并且輪流運(yùn)轉(zhuǎn),大大延長了水泵及電機(jī)的使用壽命。
