變頻恒壓供水系(xi)統(tong)對泵(beng)電機實行(xing)無級調速,根(gen)據用(yong)水(shui)(shui)(shui)量和水(shui)(shui)(shui)壓變(bian)化(hua),通過微機檢測計算,自(zi)(zi)動(dong)(dong)改變(bian)泵(beng)速,保持水(shui)(shui)(shui)壓恒定,滿足用(yong)水(shui)(shui)(shui)需求。是目前(qian)更(geng)先 進、最合理(li)的節能供水(shui)(shui)(shui)系(xi)統(tong)。與(yu)傳統(tong)的水(shui)(shui)(shui)塔、高位水(shui)(shui)(shui)箱、氣(qi)壓罐等(deng)供水(shui)(shui)(shui)方(fang)式相(xiang)比,在系(xi)統(tong)投資、運行(xing)經濟(ji)性、穩定性、可靠(kao)性、自(zi)(zi)動(dong)(dong)化(hua)等(deng)方(fang)面(mian)具(ju)有優勢,具(ju)體(ti)體(ti)現(xian)在:
(1)操作簡(jian)單,省時省力。
(2)體積(ji)小,投資少,效率高。
(3)功能(neng)齊全,配置靈活(huo),自(zi)動化程度(du)高。
(4)合理(li)運(yun)行,由于(yu) 平(ping)均(jun)轉速的(de)降低(di),軸上的(de)平(ping)均(jun)扭(niu)矩和磨損減少(shao),泵的(de)使用(yong)壽命將大大提高。
(5)高效(xiao)節能(neng)。與傳統供水方式(shi)相比,變頻恒壓(ya)供水可節能(neng)30%-60%。
(6)因(yin)為它能(neng)(neng)實現(xian)泵的軟(ruan)停、軟(ruan)啟(qi)動(dong),并能(neng)(neng)消除(chu)水錘效應(水錘效應:直接啟(qi)停時(shi),液體動(dong)能(neng)(neng)急(ji)劇增加,對管網沖擊大(da),破壞力大(da))。
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。
