變頻恒壓供水系統對(dui)泵電(dian)機實(shi)行無級調速,根據用水(shui)(shui)(shui)(shui)量和水(shui)(shui)(shui)(shui)壓(ya)變化,通(tong)過微機檢測計算,自動改變泵速,保持(chi)水(shui)(shui)(shui)(shui)壓(ya)恒定(ding)(ding),滿足(zu)用水(shui)(shui)(shui)(shui)需求(qiu)。是目前更先 進(jin)、最合(he)理的節能(neng)供(gong)水(shui)(shui)(shui)(shui)系統。與傳統的水(shui)(shui)(shui)(shui)塔、高位水(shui)(shui)(shui)(shui)箱、氣壓(ya)罐等供(gong)水(shui)(shui)(shui)(shui)方式相(xiang)比(bi),在系統投資(zi)、運行經濟性(xing)(xing)、穩定(ding)(ding)性(xing)(xing)、可靠性(xing)(xing)、自動化等方面具有(you)優勢,具體體現在:
(1)操作簡單,省(sheng)時省(sheng)力。
(2)體積小(xiao),投資少,效率高。
(3)功能齊全,配置靈活(huo),自動化(hua)程度高。
(4)合(he)理運行,由于 平均(jun)轉(zhuan)速的降(jiang)低,軸上的平均(jun)扭矩和磨(mo)損減(jian)少,泵的使(shi)用壽(shou)命將大(da)(da)大(da)(da)提高。
(5)高(gao)效節能。與傳統(tong)供(gong)水(shui)方式相比,變(bian)頻(pin)恒壓供(gong)水(shui)可節能30%-60%。
(6)因為(wei)它能(neng)實現泵的軟(ruan)停、軟(ruan)啟動,并能(neng)消除水錘效應(ying)(水錘效應(ying):直接啟停時,液體動能(neng)急劇增(zeng)加(jia),對(dui)管(guan)網沖擊大,破壞力大)。
變頻恒壓供水系統在各類住宅小區、商業寫字樓、酒店、餐廳、商場、超市、地鐵、體育場館以及專門從事消防等需要供水項目中有著極為廣泛的應用價值。
由水(shui)(shui)(shui)泵變(bian)頻(pin)柜組成的變(bian)頻(pin)恒壓(ya)供(gong)(gong)水(shui)(shui)(shui)系統以管(guan)網水(shui)(shui)(shui)壓(ya)(或用戶(hu)水(shui)(shui)(shui)流(liu)量(liang)(liang)(liang))為設(she)定(ding)參數,通過微(wei)機控制(zhi)輸出頻(pin)率(lv),自動調節泵電機轉(zhuan)速,實現管(guan)網水(shui)(shui)(shui)壓(ya)的閉環(huan)調節(PID),使供(gong)(gong)水(shui)(shui)(shui)系統自動恒定(ding)穩定(ding)在(zai)設(she)定(ding)壓(ya)力值:即用水(shui)(shui)(shui)量(liang)(liang)(liang)增(zeng)加(jia)時,頻(pin)率(lv)增(zeng)加(jia),泵速增(zeng)加(jia),供(gong)(gong)水(shui)(shui)(shui)量(liang)(liang)(liang)相應(ying)(ying)增(zeng)加(jia);用水(shui)(shui)(shui)量(liang)(liang)(liang)減少(shao)時,頻(pin)率(lv)降低,泵速減慢,供(gong)(gong)水(shui)(shui)(shui)量(liang)(liang)(liang)相應(ying)(ying)減少(shao),從而保證供(gong)(gong)水(shui)(shui)(shui)效(xiao)率(lv)。滿(man)足(zu)用戶(hu)對水(shui)(shui)(shui)壓(ya)和(he)水(shui)(shui)(shui)量(liang)(liang)(liang)的要求,同(tong)時達到提高供(gong)(gong)水(shui)(shui)(shui)質量(liang)(liang)(liang)和(he)效(xiao)率(lv)的目的。該設(she)備無(wu)需建造高位水(shui)(shui)(shui)箱(xiang)和(he)水(shui)(shui)(shui)塔,水(shui)(shui)(shui)質無(wu)二次污染。是理(li)想的現代建筑給水(shui)(shui)(shui)設(she)備。
