自動穩壓給水設(she)備一拖一恒壓供水控制原理及參(can)數設(she)置

自動(dong)穩壓給水(shui)設(she)備控制原理：

      全自動變(bian)頻(pin)(pin)自動穩壓(ya)給(gei)水設(she)備(bei)是變(bian)頻(pin)(pin)控制技術、電(dian)(dian)(dian)(dian)機(ji)泵組(zu)控制技術的(de)新型(xing)機(ji)電(dian)(dian)(dian)(dian)一體化供水裝置。通過安裝在水泵出水總管(guan)上的(de)遠傳(chuan)壓(ya)力表(biao)（內為一滑動電(dian)(dian)(dian)(dian)阻），將(jiang)出口(kou)壓(ya)力轉換成(cheng)0-5V電(dian)(dian)(dian)(dian)壓(ya)信號，經(jing)屏蔽信號線(xian)將(jiang)電(dian)(dian)(dian)(dian)壓(ya)信號回(hui)傳(chuan)給(gei)變(bian)頻(pin)(pin)器，經(jing)變(bian)頻(pin)(pin)器內部PID運(yun)算，進而控制其(qi)輸出頻(pin)(pin)率的(de)變(bian)化。當用水量(liang)降(jiang)至某一程度時(shi)（如夜間用水很少時(shi)），變(bian)頻(pin)(pin)主泵停止工作進入(ru)休眠。

主(zhu)器(qi)件：三肯變頻器(qi)、斷路器(qi)、接觸器(qi)、繼(ji)電(dian)器(qi)、燈扭(niu)、儀表(biao)

三肯變頻器調整方法：

cd1=2(外部信號控制啟(qi)動(dong)、停(ting)止，即：DII和DCM1,啟(qi)動(dong)端子閉合即啟(qi)動(dong))

cd7=50(上(shang)限(xian)頻率)

cd8=10-20(下限(xian)頻率)

cd19=加速時(shi)間      根據(ju)實際(ji)需要適當調(diao)整(zheng)10秒(miao)左右功率(lv)大適當延(yan)長時(shi)間

cd55=50(增益(yi)頻率   對應壓(ya)(ya)力(li)表(biao)的較大(da)值)如：設50對應1Mp壓(ya)(ya)力(li)表(biao)，1公(gong)斤壓(ya)(ya)力(li)值設定為cd29＝50／10＝5

cd71=3(選擇內(nei)置PID控制)

cd120＝1(壓力反饋信號為0-5V)

cd122=1.0(比例(li)增(zeng)益)

cd123＝o.5(積分增益)

cd125＝(如果壓力波(bo)動較(jiao)大、適當調大)

cd680＝120

自動(dong)穩(wen)壓給水設備原理

    自動穩(wen)壓(ya)給水(shui)(shui)設備可根據用戶需求設定用戶供(gong)(gong)水(shui)(shui)壓(ya)力(li)(li)，如果管網供(gong)(gong)水(shui)(shui)壓(ya)力(li)(li)高于設定壓(ya)力(li)(li)時(shi)，水(shui)(shui)泵機組處于停機狀態，自來水(shui)(shui)可通(tong)過連通(tong)管路直接(jie)對用戶供(gong)(gong)水(shui)(shui)。當市政管網供(gong)(gong)水(shui)(shui)壓(ya)力(li)(li)低于設定壓(ya)力(li)(li)時(shi)，設備自動進人接(jie)力(li)(li)升壓(ya)工作狀態，機組通(tong)過壓(ya)力(li)(li)傳感器，水(shui)(shui)泵及恒壓變頻控(kong)制柜(ju)組成(cheng)閉環控(kong)制系(xi)統，隨著用水量的變化，不斷(duan)調整水泵(beng)轉(zhuan)速及投入(ru)運行(xing)的水泵(beng)臺數(shu)，以保持(chi)供水壓力恒定。 

    流(liu)(liu)量調(diao)節器是密封容器，在供(gong)(gong)水(shui)管(guan)網(wang)能滿足(zu)供(gong)(gong)水(shui)要求時，此設(she)備作為供(gong)(gong)水(shui)管(guan)網(wang)與供(gong)(gong)水(shui)設(she)備之(zhi)間的(de)緩(huan)沖裝置，以消除水(shui)泵機組(zu)對管(guan)網(wang)的(de)脈動影響(xiang)。在供(gong)(gong)水(shui)管(guan)網(wang)供(gong)(gong)水(shui)量不足(zu)時，作為流(liu)(liu)量調(diao)節裝置，以緩(huan)解管(guan)網(wang)用(yong)水(shui)高峰時的(de)流(liu)(liu)量不足(zu)。

    管(guan)(guan)網保(bao)(bao)(bao)護(hu)器安裝在流量調節器上，當(dang)罐內壓力(li)較(jiao)外界壓力(li)高(gao)時(shi)，管(guan)(guan)網保(bao)(bao)(bao)護(hu)器關閉，水(shui)泵機組疊加市(shi)政(zheng)管(guan)(guan)網原有壓力(li)進行恒壓供水(shui)；當(dang)罐內壓力(li)與外界平衡(heng)時(shi)，管(guan)(guan)網保(bao)(bao)(bao)護(hu)器打開(kai)與外界相(xiang)通，避免(mian)了負(fu)壓的形(xing)成，保(bao)(bao)(bao)證市(shi)政(zheng)管(guan)(guan)網完好及其它用(yong)戶正常供水(shui)。

    供水(shui)(shui)管網(wang)停(ting)(ting)水(shui)(shui)時(shi)，設備自動停(ting)(ting)止運行，管網(wang)恢復(fu)供水(shui)(shui)自動開機。停(ting)(ting)電(dian)時(shi)，水(shui)(shui)泵機組(zu)停(ting)(ting)止工作，自來水(shui)(shui)可(ke)通(tong)過(guo)連通(tong)管直接(jie)進(jin)人用戶管網(wang)，來電(dian)時(shi)機組(zu)自動開機恢復(fu)正常供水(shui)(shui)。

　　2、自動穩(wen)壓給水設備(bei)變頻應用方式

　　　　通常(chang)在同一(yi)路供水(shui)(shui)系(xi)(xi)統(tong)中(zhong)，設置多(duo)(duo)(duo)臺(tai)(tai)常(chang)用泵，供水(shui)(shui)量大時多(duo)(duo)(duo)臺(tai)(tai)泵全(quan)開(kai)，供水(shui)(shui)量小時開(kai)一(yi)臺(tai)(tai)或(huo)兩臺(tai)(tai)。在采用變(bian)頻恒壓(ya)(ya)自動(dong)(dong)穩(wen)壓(ya)(ya)給水(shui)(shui)設備進行恒壓(ya)(ya)供水(shui)(shui)時，就用兩種(zhong)(zhong)(zhong)方式(shi)，其(qi)一(yi)是(shi)所有水(shui)(shui)泵配(pei)用一(yi)臺(tai)(tai)變(bian)頻器；其(qi)二(er)是(shi)每臺(tai)(tai)水(shui)(shui)泵配(pei)用一(yi)臺(tai)(tai)變(bian)頻器。后(hou)種(zhong)(zhong)(zhong)方法根據(ju)壓(ya)(ya)力反饋(kui)信號，通過PID運算自動(dong)(dong)調整變(bian)頻器輸出頻率，改變(bian)電動(dong)(dong)機轉(zhuan)速(su)，達(da)到管網恒壓(ya)(ya)的(de)(de)(de)目的(de)(de)(de)，就一(yi)個(ge)閉(bi)環回路，較簡單，但(dan)成本高。前種(zhong)(zhong)(zhong)方法成本低，性能不比后(hou)種(zhong)(zhong)(zhong)差，但(dan)控制程序較復(fu)雜，是(shi)未來(lai)的(de)(de)(de)發(fa)展方向(xiang)，我公(gong)司開(kai)發(fa)中(zhong)贏系(xi)(xi)列變(bian)頻恒壓(ya)(ya)自動(dong)(dong)穩(wen)壓(ya)(ya)給水(shui)(shui)設備系(xi)(xi)統(tong)就可實現一(yi)變(bian)頻器控制任意數馬(ma)達(da)的(de)(de)(de)功能。下面(mian)講到的(de)(de)(de)原理(li)都是(shi)一(yi)變(bian)頻器拖動(dong)(dong)多(duo)(duo)(duo)馬(ma)達(da)的(de)(de)(de)系(xi)(xi)統(tong)。

　　3、自動(dong)穩(wen)壓給水設備PID控制原理

　　　　根據反饋原理(li)(li)：要想維(wei)持一個物(wu)理(li)(li)量(liang)不(bu)(bu)變(bian)或基(ji)本(ben)不(bu)(bu)變(bian)，就(jiu)應該引這(zhe)個物(wu)理(li)(li)量(liang)與恒(heng)值比較(jiao)，形成閉環(huan)系統(tong)。我們要想保(bao)持水壓的(de)恒(heng)定，因此就(jiu) 須引入水壓反饋值與給定值比較(jiao)，從(cong)而形成閉環(huan)系統(tong)。但被控(kong)(kong)制(zhi)的(de)系統(tong)特點是(shi)非線(xian)性(xing)、大慣(guan)性(xing)的(de)系統(tong)，現(xian)在(zai)控(kong)(kong)制(zhi)和PID相結合的(de)方(fang)法，在(zai)壓力(li)波動較(jiao)大時(shi)(shi)使用(yong)(yong)模糊(hu)控(kong)(kong)制(zhi)，以加快(kuai)響應速度；在(zai)壓力(li)范(fan)圍較(jiao)小時(shi)(shi)采用(yong)(yong)PID來(lai)保(bao)持靜態精度。這(zhe)通過PLC加智(zhi)能儀(yi)表可(ke)時(shi)(shi)現(xian)該算法，同時(shi)(shi)對PLC的(de)編程來(lai)時(shi)(shi)現(xian)泵(beng)的(de)工頻與變(bian)頻之間的(de)切換(huan)。實踐證明(ming)，使用(yong)(yong)這(zhe)種方(fang)法是(shi)可(ke)行的(de)，而且造價也不(bu)(bu)高。

　　　　變頻恒(heng)壓(ya)自動穩壓(ya)給水(shui)設(she)備要想維持供水(shui)網的壓(ya)力(li)不(bu)變，根據反饋定(ding)理(li)(li)在管(guan)(guan)網系統的管(guan)(guan)理(li)(li)上安裝了(le)壓(ya)力(li)變送器(qi)作為(wei)反饋元件，由于供水(shui)系統管(guan)(guan)道(dao)長、管(guan)(guan)徑大(da)，管(guan)(guan)網的充壓(ya)都較慢，故系統是一個(ge)大(da)滯后系統，不(bu)易直接采用PID調(diao)節(jie)器(qi)進行控制(zhi)，而采用PLC參與控制(zhi)的方式來實現對(dui)控制(zhi)系統調(diao)節(jie)作用。
