變頻恒壓供水系(xi)統對泵電機實行(xing)(xing)無級調(diao)速，根據用水量和水壓變(bian)化(hua)，通(tong)過微(wei)機檢測計算，自(zi)動改變(bian)泵速，保持(chi)水壓恒(heng)定，滿足用水需求。是目(mu)前更先 進、最合理的節(jie)能(neng)供水系(xi)統。與傳統的水塔、高位水箱、氣壓罐等(deng)供水方(fang)(fang)式相比，在系(xi)統投資、運行(xing)(xing)經(jing)濟性、穩定性、可靠(kao)性、自(zi)動化(hua)等(deng)方(fang)(fang)面具有優勢(shi)，具體體現在:
(1)操作簡單，省時省力。
(2)體積(ji)小，投資(zi)少(shao)，效率高。
(3)功能齊(qi)全，配置靈活，自動化程度(du)高。
(4)合理(li)運行，由于 平(ping)均轉速的(de)降低，軸上的(de)平(ping)均扭矩和磨損減少，泵(beng)的(de)使用壽命將大(da)大(da)提高。
(5)高效節能。與傳(chuan)統供水方(fang)式相比，變頻恒壓供水可節能30%-60%。
(6)因為(wei)它能(neng)實現泵的軟停、軟啟動(dong)(dong)，并(bing)能(neng)消除水(shui)錘(chui)效(xiao)(xiao)應(ying)(水(shui)錘(chui)效(xiao)(xiao)應(ying):直接(jie)啟停時，液體動(dong)(dong)能(neng)急劇增加，對管網(wang)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。
