如何進行水處理

衡美水處理為您介紹一種經久耐用、性能優越的水處理設備——供水設備,并為您對其作用做具體分析

供水

十、靜音設備

1、產品概述

具有普通型無負壓供水設備的所有功能特征外,產品更顯示出環保衛生,低噪音,不擾民”的設計理念。該電機選用全不銹鋼充水式電機,對水質無任何污染,其主過流部件均采用304不銹鋼等材料制造。設備結構形成一個密閉系統,因此運行無噪音。該產品將成為二次增壓供水前景寬廣的設備之一。

2、產品特點

1、節省投資

該設備無須水池、水箱等儲水設施,也可無須專用泵房,節省占地面積,減少建筑費用。

2、超靜音優勢

該設備具有防振和消音功能,超靜音平穩運行,無水錘、電機運行等噪音污染,聲音控制30分貝以內。

3、有效節能

該設備能與自來水管網直接串接,充分利用市政給水管網壓力,在其基礎上差多少補多少,即設備只對自來水的進水壓力和所需壓力的差進行補壓,當自來水壓力滿足要求時設備停止工作,全部由市政壓力直供。與普通供水設備相比,可節電達百分之九十。

4停電不斷水

供電線路停電時,能自動切換為市政自來水壓力供水,維持自來水管網原有壓力。

5環保衛生

電機采用全不銹鋼屏蔽式充水式電機,采用品牌水潤滑軸承,無需油脂,水潤滑、水循環、水冷卻,避免了水的二次污染,實現全不銹鋼配置。

6無負壓供水

該設備具有市政管網保護功能,在與市政管網直聯取水加壓運行過程中不會對市政自來水管網造成負壓。由于市政管網隨著用戶的增減,壓力隨之波動,當市政管網壓力下降至警戒壓力時,該設備的保壓系統會自動偵得信號并將之傳輸到電氣控制系統,使泵組從市政管網減少吸水或停止吸水,從而保證市政管網的壓力不受干擾。

7智能化程度高

設備采用電腦系統來感測,傳導壓力信號,確保準確無誤;并能實現全自動智能控制,具有手動/自動切換、主副泵定時輪換、壓力調整、恒壓、高低電壓保護、欠相保護、漏電保護、過載保護、過熱保護、缺水失壓保護、漏水偵測補償、不用水停車、瞬間跳閘保護等功能,配備RS485總線接口可實現可視化遠程調整、監測和維護

8造型美觀,檔次高,設備使用壽命長。

十一、變頻供水設備

1、產品

具備了無負壓供水的所有功能特征,而且更具有其獨到的特點:運行超靜音結構一體化

該設備的屏蔽式不銹鋼水泵機組完全置于密閉的屏蔽式不銹鋼穩流罐中,使無負壓供水機組的運行狀態達到超靜音效果。并且其質優價廉,做到了超靜音供水設備“平民化”,必將成為無負壓供水市場的新寵兒。

2、適用范圍

環境要求高、無噪音、無震動、占地小、配置高的小區、別墅、學校、醫院、機關、大中城市的高層住宅小區、公寓、辦公樓、寫字樓、賓館等建筑日常用水和生活用水。

十二、雙模設備

1、產品概述

雙模變頻供水設備是在原有通用型水池(水箱)式變頻供水設備和無負壓管網疊壓變頻供水設備基礎上開發出來的智能化供水設備。

產品把水池(水箱)式變頻供水設備和無負壓管網疊壓變頻供水設備巧妙地結合在一起,實現了節能、環保、運行可靠、用水高峰不斷水、停電可維持自來水水壓供水等優點,把二次供水設備的技術水平提升到了一個新的高度,標志著供水設備二次革命時代的來臨,具有社會效益和經濟效益。

2、產品特點

1雙模式供水

具有水池(水箱)式變頻供水設備和無負壓管網疊壓變頻供水設備兩種模式供水,可根據自來水進水壓力及流量自動切換,此種運行方式不但避免了市政管網負壓的產生,并且保證了供水的連續性,這個功能是通用型無負壓供水設備無法做到的。

2節能,運行成本低

可充分利用市政管網供水壓力,差多小,補多少,不產生負壓,與傳統水池(水箱)式變頻供水設備相比可節能達百分之九十

3定時換新功能

控制系統定時對水池(水箱)中的水自動進行換新,以保持水池(水箱)中的水的新鮮程度。

4運行可靠

停電可維持市政管網水壓供水;當用水高峰或自來水停水時,由水池(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。

5保護功能齊全

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功能。在異常情況下能進行信號報警、自檢、故障判斷等。

6占地少安裝方便

整套設備只有一組供水控制柜和水泵機組,安裝非常簡單方便。

7延長設備的使用壽命

對泵組均能可靠的實現軟啟動,使電網和管網免沖擊,并且輪流運轉,大大延長了水泵及電機的使用壽命。設備壽命比傳統水池(水箱)變頻供水設備大大提高。

3、適用范圍

1各種已建、在建、待建的住宅小區、公寓、辦公樓、寫字樓、賓館飯店、學校、醫院等建筑二次供水系統應用

2特別適用于高峰期間自來水水壓低、水流小的不穩定的高層、小高層住宅小區、賓館、辦公樓的生活用水。

3離市區較偏、自來水壓較低的工礦企業生活、生產用水。

4原有氣壓式、水池(水箱)式變頻供水設備的改造工程

十三、箱式智能變頻設備

1、產品概述

箱式智能變頻供水設備代替了傳統水塔,廣泛適用于以下場所:

工礦企業生產用水

寫字樓、辦公樓、商場、醫院、學校等生活、消防用水;

居民小區生活用水,采暖、空調循環水系統定壓,現代農業噴灌,城市、鄉村自來水廠供水;

賓館、飯店生活冷、熱水供應;地震、災區臨時應爭給水。

2、產品特點

1一體化設計,結構緊湊,系統直接安裝在水箱里(如在室外可減少泵房的建設)投資少,安裝方便,外形美觀。

2利用管網壓力的疊加以及自動變頻運行方式,節能效果得到顯著提高

3配套安裝方便,只有一個市政管網進口和一個供水出口。

4運行穩定,振動小,噪音低(噪音值低于70分貝)。

5系統供水穩定(即使管網臨時斷水,也能通過水箱正常供水),充分保證系統末端壓力。

6可附加巡檢自動功能,降低物業管理費用。

7采用PLC可編程控制全自動運行,操作維護方便。

3、使用要求

1箱式智能變頻供水設備使用前手盤水泵轉子,應無摩擦、卡滯現象;

2500V低壓插表檢測電機絕緣,應為0.5MΩ以上;

3遠傳壓力表插座1、2、3(黃、藍、紅)分別接端子1、2、3。或用萬用表測遠傳壓力表的電阻值,電阻值為1和2,另一根為3,與3電阻值小的為1,與3電阻值大的為2。萬用表檢測一下,否則接錯線將燒壞表;

1遠傳壓力表應安裝至用戶管網上,出口止回閥后的總管上;

2控制儀表及線路無損壞;

3變頻柜送電后,嚴禁先動變頻器參數;

4打開水泵排氣閥,排除氣體;

5本系統啟動或維護、維修后,起動時應打開進水閥,關閉出口閥門;檢查系統各處是否有瀉漏。如有應將瀉漏排除后再進行啟動;

6首先檢查水泵在自動時水泵轉向,如為反轉則對調電源進線任意兩相線線位;再轉到手動起動每臺泵,如為反轉同樣對調水泵電機線;

7手動逐臺啟停水泵,檢查水泵運轉無異常現象;

3鍋爐系統中用的補充水箱,保溫水箱。

4食品、飲料、制藥、釀造等行業水凈化、水處理的原裝箱,凈水箱及物料貯存設備。

十四、設備選型

1、設備每小時流量Q(/h)的確定

Q=【(m×q)/1000t】×K

Q每小時流量(/h)

K—變化系數(一般為1.5-2.5)

q—用水標準(華南一般采用300升/人.日;住宅采用400升/人.日)

t—用水時間(一般采用12小時/日)

m—用水人數(一般一戶按4-5人計算)

2、設備額定揚程H(m)的確定

1建筑層數:1,2,3,4,5,6,7,8,9...

2水壓:15,19,23,27,31,35,39,43...每增加一層揚程增加4米

說明:建筑物所需有效供水壓力減除市政供水或外來水壓即為設備的揚程。

3、驗證所選水泵流量是否高于市政供水量

根據流量計算公式:Q=π×r)² ×V

按照GB50015-2003《建筑給排水設計規范》要求,生活給水管道的水流速取1.0-1.5m/s。

市政供水小時流量大于小區每小時所需流量,否則不建議選擇無負壓變頻供水設備。
