無負壓(ya)供水控制(zhi)系(xi)統(tong)讓生(sheng)活(huo)供水更(geng)先進水質(zhi)更(geng)清潔

1、供水(shui)方式

        原傳統供(gong)(gong)(gong)(gong)水(shui)(shui)(shui)(shui)(shui)(shui)方式(shi)采用(yong)地(di)(di)下水(shui)(shui)(shui)(shui)(shui)(shui)池(chi)和水(shui)(shui)(shui)(shui)(shui)(shui)泵(beng)聯合供(gong)(gong)(gong)(gong)水(shui)(shui)(shui)(shui)(shui)(shui)的(de)(de)方式(shi)，即由市政外網供(gong)(gong)(gong)(gong)水(shui)(shui)(shui)(shui)(shui)(shui)至地(di)(di)下生(sheng)活水(shui)(shui)(shui)(shui)(shui)(shui)池(chi)，利用(yong)水(shui)(shui)(shui)(shui)(shui)(shui)泵(beng)提升來滿足用(yong)戶(hu)的(de)(de)用(yong)水(shui)(shui)(shui)(shui)(shui)(shui)量(liang)(liang)及用(yong)水(shui)(shui)(shui)(shui)(shui)(shui)壓力(li)。該方案(an)雖能滿足供(gong)(gong)(gong)(gong)水(shui)(shui)(shui)(shui)(shui)(shui)壓力(li)的(de)(de)穩定性(xing)和供(gong)(gong)(gong)(gong)水(shui)(shui)(shui)(shui)(shui)(shui)量(liang)(liang)的(de)(de)可靠性(xing)，但由于自來水(shui)(shui)(shui)(shui)(shui)(shui)全部被(bei)放入水(shui)(shui)(shui)(shui)(shui)(shui)池(chi)中，再經水(shui)(shui)(shui)(shui)(shui)(shui)泵(beng)二次(ci)加壓提升至水(shui)(shui)(shui)(shui)(shui)(shui)箱向用(yong)戶(hu)供(gong)(gong)(gong)(gong)水(shui)(shui)(shui)(shui)(shui)(shui)，不能利用(yong)自來水(shui)(shui)(shui)(shui)(shui)(shui)原有壓力(li)，系(xi)統電耗(hao)大，安(an)裝維護麻煩，同時因需設置地(di)(di)下水(shui)(shui)(shui)(shui)(shui)(shui)池(chi)而(er)帶來的(de)(de)如(ru)一(yi)次(ci)性(xing)基(ji)建投資大，并且(qie)易(yi)造成二次(ci)污染(ran)、漏(lou)水(shui)(shui)(shui)(shui)(shui)(shui)等一(yi)系(xi)列弊病。

       現在選用(yong)(yong)(yong)中(zhong)贏無負壓(ya)供(gong)(gong)水(shui)(shui)控制(zhi)(zhi)系(xi)統(tong)設備(bei)即管網增壓(ya)穩流供(gong)(gong)水(shui)(shui)方(fang)式，不(bu)(bu)需(xu)修建水(shui)(shui)池和加設水(shui)(shui)箱。二次(ci)加壓(ya)供(gong)(gong)水(shui)(shui)可(ke)直接串(chuan)接在自(zi)來水(shui)(shui)管網上(shang)，采用(yong)(yong)(yong)密閉式穩流補償器和真空抑制(zhi)(zhi)及(ji)補償系(xi)統(tong)，利用(yong)(yong)(yong)微電(dian)腦控制(zhi)(zhi)，自(zi)動(dong)調節，使自(zi)來水(shui)(shui)管道不(bu)(bu)產(chan)生負壓(ya)。因此中(zhong)贏無負壓(ya)供(gong)(gong)水(shui)(shui)控制(zhi)(zhi)系(xi)統(tong)設備(bei)不(bu)(bu)僅不(bu)(bu)會影響周圍用(yong)(yong)(yong)戶的(de)用(yong)(yong)(yong)水(shui)(shui)，而且可(ke)充分利用(yong)(yong)(yong)自(zi)來水(shui)(shui)原(yuan)有的(de)壓(ya)力，達到節能(neng)的(de)目的(de)(節電(dian)可(ke)達50%～90%以上(shang))，另外(wai)可(ke)消除(chu)因修建水(shui)(shui)池而引起的(de)一系(xi)列弊病。

    中贏無(wu)負壓供(gong)水控制系統(tong)設備工(gong)作的原理是通過微機檢(jian)測管(guan)網壓(ya)力(li)的負壓(ya)反饋來調(diao)節變(bian)(bian)頻(pin)(pin)器(qi)的頻(pin)(pin)率(lv)。首先根(gen)據實際(ji)情況設(she)(she)定(ding)用(yong)水點工(gong)作壓(ya)力(li)，檢(jian)測出水管(guan)實際(ji)壓(ya)力(li)并與設(she)(she)定(ding)壓(ya)力(li)進行比較，如果實際(ji)壓(ya)力(li)高于設(she)(she)定(ding)壓(ya)力(li)，則降低(di)變(bian)(bian)頻(pin)(pin)器(qi)頻(pin)(pin)率(lv)，反之升高變(bian)(bian)頻(pin)(pin)器(qi)頻(pin)(pin)率(lv)。工(gong)控(kong)微機隨時檢(jian)測管(guan)網壓(ya)力(li)，并且計算速度很快，調(diao)節速度也是瞬時完成的，使管(guan)網壓(ya)力(li)始終保持(chi)在設(she)(she)定(ding)壓(ya)力(li)上。

      另(ling)外全密封結構及負(fu)壓(ya)(ya)(ya)反饋抑(yi)制(zhi)系(xi)統使本設備可(ke)(ke)以(yi)和自來(lai)水直接串接，由(you)于(yu)水泵工作(zuo)有疊加原理，使設備可(ke)(ke)以(yi)充分利用自來(lai)水原有的(de)壓(ya)(ya)(ya)力，增加了無負(fu)壓(ya)(ya)(ya)供水控制(zhi)系(xi)統設備的(de)節能點。當自來(lai)水壓(ya)(ya)(ya)力不足，致使壓(ya)(ya)(ya)力下降時(shi)，設備通過系(xi)統中的(de)檢(jian)測裝置(zhi)采集水量及壓(ya)(ya)(ya)力信(xin)號，實時(shi)反饋，通過微機控制(zhi)，自動調節，抑(yi)制(zhi)管網負(fu)壓(ya)(ya)(ya)產(chan)生(sheng)，保(bao)證(zheng)了設備不對城市管網產(chan)生(sheng)任(ren)何影響。

2、供水(shui)質量

      根據有關(guan)專家研究，生(sheng)活飲用水(shui)(shui)(shui)(shui)產生(sheng)二次污(wu)染主(zhu)要(yao)環(huan)節是(shi)在二次加壓系(xi)統(tong)中的(de)(de)起調節作(zuo)用的(de)(de)水(shui)(shui)(shui)(shui)池和水(shui)(shui)(shui)(shui)箱(xiang)。因為將純凈的(de)(de)自來水(shui)(shui)(shui)(shui)放(fang)入(ru)水(shui)(shui)(shui)(shui)池或水(shui)(shui)(shui)(shui)箱(xiang)中，各種(zhong)雜質(zhi)(zhi)(zhi)、污(wu)染物極(ji)易進入(ru)水(shui)(shui)(shui)(shui)中，尤其是(shi)夏天，水(shui)(shui)(shui)(shui)質(zhi)(zhi)(zhi)極(ji)易變質(zhi)(zhi)(zhi)、變味，嚴(yan)重污(wu)染了(le)水(shui)(shui)(shui)(shui)源(yuan)，影響了(le)人們的(de)(de)身體健康。另外，水(shui)(shui)(shui)(shui)池或水(shui)(shui)(shui)(shui)箱(xiang)的(de)(de)制作(zuo)材質(zhi)(zhi)(zhi)或防腐選擇不(bu)當，也將直接污(wu)染水(shui)(shui)(shui)(shui)質(zhi)(zhi)(zhi)。

      中(zhong)贏無(wu)(wu)負壓(ya)供水(shui)控(kong)制系(xi)統(tong)(tong)設備無(wu)(wu)任(ren)何中(zhong)間(jian)調節裝置(zhi)，無(wu)(wu)地(di)下(xia)生活水(shui)箱和高位水(shui)箱，且為全(quan)封閉系(xi)統(tong)(tong)，取消了(le)(le)(le)二次污染的(de)主要(yao)環(huan)節，保證(zheng)了(le)(le)(le)供水(shui)系(xi)統(tong)(tong)中(zhong)的(de)水(shui)質安(an)(an)全(quan)。同(tong)時設備本身采用(yong)不(bu)銹(xiu)鋼(gang)優質材料配置(zhi)，徹底杜(du)絕了(le)(le)(le)二次加壓(ya)供水(shui)系(xi)統(tong)(tong)中(zhong)的(de)二次污染，保證(zheng)了(le)(le)(le)用(yong)戶(hu)的(de)供水(shui)安(an)(an)全(quan)。

3、投資情況(kuang)

       中(zhong)贏無負壓供(gong)水(shui)(shui)控制系(xi)統設(she)備(bei)(bei)(bei)(bei)可(ke)直接串(chuan)接到任何(he)自來水(shui)(shui)壓力不足的管網上(shang)進行加壓供(gong)水(shui)(shui)，不需修建水(shui)(shui)池(chi)水(shui)(shui)箱，同時也可(ke)省(sheng)去因二(er)次污染(ran)(ran)而(er)(er)投入的消(xiao)毒(du)設(she)備(bei)(bei)(bei)(bei)。省(sheng)掉了水(shui)(shui)池(chi)水(shui)(shui)箱等(deng)構筑物的修建費用及水(shui)(shui)質(zhi)二(er)次污染(ran)(ran)的消(xiao)毒(du)處理費用，少則幾萬(wan)(wan)，多則十幾萬(wan)(wan)。就本項(xiang)目而(er)(er)言，傳統供(gong)水(shui)(shui)方案需設(she)置壹個容(rong)積V= 40 m3不銹鋼裝配式水(shui)(shui)箱，初步估計需投資約(yue) 6萬(wan)(wan)元(yuan)(yuan)(yuan)(yuan)；因自來水(shui)(shui)水(shui)(shui)質(zhi)二(er)次污染(ran)(ran)而(er)(er)加設(she)一套紫外線臭氧一體化消(xiao)毒(du)設(she)備(bei)(bei)(bei)(bei)需投資設(she)備(bei)(bei)(bei)(bei)費約(yue) 3萬(wan)(wan)元(yuan)(yuan)(yuan)(yuan)；水(shui)(shui)泵電機等(deng)設(she)備(bei)(bei)(bei)(bei)約(yue)4萬(wan)(wan)元(yuan)(yuan)(yuan)(yuan)；而(er)(er)無負壓整套設(she)備(bei)(bei)(bei)(bei)約(yue) 9萬(wan)(wan)元(yuan)(yuan)(yuan)(yuan)，設(she)備(bei)(bei)(bei)(bei)上(shang)預計可(ke)節(jie)省(sheng)5萬(wan)(wan)元(yuan)(yuan)(yuan)(yuan)左右。

4、節能分析

      傳統供(gong)水(shui)(shui)(shui)(shui)方案(an)是將自(zi)(zi)(zi)來(lai)(lai)水(shui)(shui)(shui)(shui)放入地下(xia)水(shui)(shui)(shui)(shui)池，原(yuan)有的(de)(de)市政管網(wang)的(de)(de)壓力(li)全部變為零，再從零開始(shi)重新加壓供(gong)水(shui)(shui)(shui)(shui)各用水(shui)(shui)(shui)(shui)點(dian)，存在著(zhu)自(zi)(zi)(zi)來(lai)(lai)水(shui)(shui)(shui)(shui)原(yuan)有供(gong)水(shui)(shui)(shui)(shui)壓力(li)被白(bai)白(bai)浪費。而中贏無負壓供(gong)水(shui)(shui)(shui)(shui)控(kong)制系統設(she)(she)備與(yu)自(zi)(zi)(zi)來(lai)(lai)水(shui)(shui)(shui)(shui)管網(wang)直接串接，可(ke)以充分利(li)用自(zi)(zi)(zi)來(lai)(lai)水(shui)(shui)(shui)(shui)管網(wang)的(de)(de)壓力(li)，采用變頻調速，設(she)(she)備的(de)(de)電(dian)機(ji)泵在微機(ji)控(kong)制的(de)(de)控(kong)制下(xia)，根據自(zi)(zi)(zi)來(lai)(lai)水(shui)(shui)(shui)(shui)的(de)(de)壓力(li)來(lai)(lai)調節(jie)電(dian)機(ji)的(de)(de)轉速，只對(dui)自(zi)(zi)(zi)來(lai)(lai)水(shui)(shui)(shui)(shui)的(de)(de)進水(shui)(shui)(shui)(shui)壓力(li)和所需壓力(li)的(de)(de)差進行補壓，當自(zi)(zi)(zi)來(lai)(lai)水(shui)(shui)(shui)(shui)滿足(zu)要求時設(she)(she)備就停止(zhi)工(gong)作，而由自(zi)(zi)(zi)來(lai)(lai)水(shui)(shui)(shui)(shui)直接供(gong)用戶，與(yu)其他供(gong)水(shui)(shui)(shui)(shui)設(she)(she)備相比，節(jie)電(dian)可(ke)達50%～80%以上

   小流(liu)量(liang)保壓(ya)時間約10小時，小流(liu)量(liang)時微機(ji)控(kong)制自(zi)動停機(ji)保壓(ya)（需(xu)配置氣壓(ya)罐(guan)），耗電基本為(wei)零。

   與其他供(gong)水(shui)方案(an)相比(bi)，選用中贏無負壓（直(zhi)供(gong)水(shui)）管網增壓穩流供(gong)水(shui)設備可節省年運(yun)行電費△E= 0.6  萬元(yuan)/年。

5、占地方面

      傳(chuan)統(tong)供(gong)(gong)水(shui)方式需設置地(di)(di)下水(shui)箱和高位(wei)水(shui)箱等調節(jie)裝置，其儲(chu)水(shui)箱凈高為2米(mi)， 1個地(di)(di)下水(shui)池占地(di)(di)面(mian)(mian)積(ji)為30m2，選(xuan)用(yong)中(zhong)贏無負(fu)壓供(gong)(gong)水(shui)控制系統(tong)設備的(de)供(gong)(gong)水(shui)方案占地(di)(di)面(mian)(mian)積(ji)約為6m2。節(jie)省(sheng)面(mian)(mian)積(ji)約24m2，這(zhe)部分節(jie)省(sheng)的(de)面(mian)(mian)積(ji)可作(zuo)它用(yong)，如作(zuo)車庫或倉(cang)庫等。

6、管理費用(yong)

       原傳統供水方案(an)中所設的水箱(xiang)構筑物需(xu)定(ding)期清洗(xi)（掃）和處理，按(an)國家城市供水條例明文規定(ding)，水池、水箱(xiang)應每半年清洗(xi)一次(ci)，而且還要停(ting)水1天。同時，在(zai)管(guan)理上還存在(zai)著對供水安全的擔憂，并需(xu)要相應增加(jia)必要的安全防護措施費用。

      而中贏(ying)無(wu)負壓供(gong)水控制(zhi)系(xi)統設(she)備采用全自動(dong)運(yun)行，不需專(zhuan)人(ren)值守，在設(she)(she)(she)備(bei)設(she)(she)(she)定的供(gong)水壓力下，系統全智能運(yun)行水泵自動(dong)切換(huan)，使設(she)(she)(she)備(bei)的使用壽命(ming)比傳(chuan)統設(she)(she)(she)備(bei)壽命(ming)延長3倍以上。設(she)(she)(she)備(bei)質量可靠，維護管理運(yun)行都極為簡(jian)單方便，無需設(she)(she)(she)專(zhuan)人(ren)看護管理，減(jian)少了人(ren)力資源的浪費(fei)。 

7、節水方面

    中贏無負(fu)壓供水控制系統(tong)設備采用全密閉結構系統(tong)，徹底(di)防治(zhi)了(le)有(you)地下水箱(xiang)的(de)跑、冒、滴、漏等浪費水資(zi)源(yuan)(yuan)的(de)現象，同時(shi)也節省了(le)定(ding)期清洗水箱(xiang)時(shi)而造成對水資(zi)源(yuan)(yuan)的(de)浪費。

8、設計、施(shi)工及(ji)安裝(zhuang)等方面

      傳統(tong)供(gong)水(shui)方案(an)中設(she)有水(shui)池水(shui)箱等構筑(zhu)物，相應地(di)增(zeng)加了供(gong)水(shui)系統(tong)中管路的復雜性和安(an)裝維護的不方便性，因為水(shui)池水(shui)箱均需設(she)有浮球閥、溢水(shui)閥，泄水(shui)管等復雜的管路系統(tong)。而(er)中贏(ying)無負壓供(gong)水(shui)控制系統(tong)設(she)備減少了水(shui)箱，簡化了供(gong)水(shui)系統(tong)的設(she)計和安(an)裝。

綜合結論

      原(yuan)傳統(tong)供水方(fang)案：一(yi)次(ci)性(xing)投(tou)(tou)資大(da)，易造(zao)成(cheng)(cheng)二次(ci)污染，不(bu)能(neng)(neng)利(li)用自來水原(yuan)有(you)的供水壓力(li)而(er)造(zao)成(cheng)(cheng)能(neng)(neng)量浪費大(da)，正常運行費用高(gao)，自動化(hua)程度低，日常維(wei)護需投(tou)(tou)入大(da)量的人力(li)、物力(li)和財力(li)，同時存在供水質量的不(bu)安全隱(yin)患。

      采用(yong)中贏無負壓供(gong)水控制系統設(she)備(bei)，可省去地下水箱和水處理設(she)備(bei)，不僅可節約一次性投資約10萬元，而且運行(xing)費用(yong)低，供(gong)水質(zhi)量安全、可靠、衛生，設(she)備(bei)維護管理簡(jian)單方便。

      此外，選用(yong)(yong)中(zhong)(zhong)贏無負壓(ya)(ya)(ya)(ya)供水(shui)(shui)控(kong)(kong)(kong)(kong)制(zhi)系統(tong)(tong)設(she)備(bei)(bei)(bei)具有過(guo)壓(ya)(ya)(ya)(ya)、過(guo)流(liu)(liu)、過(guo)載、水(shui)(shui)源(yuan)無水(shui)(shui)、語(yu)音報(bao)警等多種保護功能(neng)，設(she)備(bei)(bei)(bei)完全模(mo)擬(ni)人腦智能(neng)技(ji)術對(dui)設(she)備(bei)(bei)(bei)進(jin)(jin)行(xing)全自動控(kong)(kong)(kong)(kong)制(zhi)，自動化程(cheng)(cheng)度高(gao)；而且(qie)還可(ke)(ke)根據用(yong)(yong)戶需要(yao)配備(bei)(bei)(bei)遠程(cheng)(cheng)監(jian)控(kong)(kong)(kong)(kong)、監(jian)測系統(tong)(tong)，實(shi)現24小時(shi)對(dui)設(she)備(bei)(bei)(bei)的(de)實(shi)時(shi)監(jian)測，也(ye)可(ke)(ke)協助(zhu)用(yong)(yong)戶建立(li)一套集中(zhong)(zhong)監(jian)控(kong)(kong)(kong)(kong)中(zhong)(zhong)心(xin)，監(jian)測水(shui)(shui)泵電(dian)流(liu)(liu)、電(dian)壓(ya)(ya)(ya)(ya)、進(jin)(jin)出水(shui)(shui)管的(de)壓(ya)(ya)(ya)(ya)力、水(shui)(shui)泵頻率等，一旦(dan)出現異常，設(she)備(bei)(bei)(bei)立(li)即報(bao)警，一些軟故障（如突然的(de)電(dian)磁干擾、電(dian)壓(ya)(ya)(ya)(ya)的(de)波(bo)動等引起的(de)故障），可(ke)(ke)通過(guo)遠程(cheng)(cheng)監(jian)控(kong)(kong)(kong)(kong)來消除；另外在(zai)監(jian)控(kong)(kong)(kong)(kong)中(zhong)(zhong)心(xin)還可(ke)(ke)遠程(cheng)(cheng)控(kong)(kong)(kong)(kong)制(zhi)設(she)備(bei)(bei)(bei)的(de)啟停(ting)(ting)等。同時(shi)采(cai)用(yong)(yong)專利技(ji)術----小流(liu)(liu)量(liang)停(ting)(ting)機(ji)功能(neng)，在(zai)用(yong)(yong)水(shui)(shui)量(liang)大時(shi)，用(yong)(yong)水(shui)(shui)全由(you)加(jia)壓(ya)(ya)(ya)(ya)設(she)備(bei)(bei)(bei)直接(jie)供至用(yong)(yong)戶，在(zai)小流(liu)(liu)量(liang)或不用(yong)(yong)水(shui)(shui)時(shi)，由(you)微機(ji)控(kong)(kong)(kong)(kong)制(zhi)中(zhong)(zhong)心(xin)檢(jian)測信號，控(kong)(kong)(kong)(kong)制(zhi)系統(tong)(tong)自動停(ting)(ting)機(ji)并保壓(ya)(ya)(ya)(ya)，節(jie)能(neng)效果顯著(zhu)，技(ji)術先進(jin)(jin)，方案可(ke)(ke)行(xing)。
