變頻恒壓供水系(xi)統對(dui)泵(beng)電機實行無(wu)級調(diao)速(su)，根據(ju)用水(shui)(shui)量和水(shui)(shui)壓(ya)變(bian)化(hua)，通過(guo)微機檢測計算，自(zi)動(dong)(dong)改變(bian)泵(beng)速(su)，保持(chi)水(shui)(shui)壓(ya)恒定，滿足用水(shui)(shui)需求。是目前更先 進、最合(he)理(li)的節(jie)能(neng)供水(shui)(shui)系(xi)統。與(yu)傳統的水(shui)(shui)塔、高(gao)位水(shui)(shui)箱、氣壓(ya)罐等供水(shui)(shui)方式(shi)相比(bi)，在系(xi)統投資(zi)、運行經濟性、穩(wen)定性、可靠性、自(zi)動(dong)(dong)化(hua)等方面具有優勢(shi)，具體(ti)體(ti)現在:
(1)操作(zuo)簡單，省(sheng)時(shi)省(sheng)力。
(2)體積小，投資少，效(xiao)率高。
(3)功能齊全，配置靈活，自動化(hua)程度高。
(4)合(he)理運行(xing)，由于 平(ping)(ping)均(jun)轉速的(de)降低，軸(zhou)上的(de)平(ping)(ping)均(jun)扭矩和磨(mo)損減少，泵的(de)使(shi)用壽命(ming)將(jiang)大大提(ti)高(gao)。
(5)高效節能(neng)。與傳統供(gong)水(shui)方式相比，變頻(pin)恒壓供(gong)水(shui)可節能(neng)30%-60%。
(6)因為(wei)它能(neng)實現(xian)泵的軟(ruan)停、軟(ruan)啟(qi)動(dong)，并(bing)能(neng)消除水錘效(xiao)應(水錘效(xiao)應:直接啟(qi)停時，液體(ti)動(dong)能(neng)急劇增(zeng)加，對管網沖擊(ji)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(you)水(shui)(shui)(shui)泵(beng)變(bian)頻柜(ju)組成的變(bian)頻恒(heng)壓(ya)供(gong)(gong)(gong)(gong)水(shui)(shui)(shui)系統以管網水(shui)(shui)(shui)壓(ya)(或(huo)用(yong)戶(hu)水(shui)(shui)(shui)流量)為(wei)設(she)(she)(she)(she)定(ding)參(can)數(shu)，通過微機控制輸出頻率，自動調節泵(beng)電機轉(zhuan)速，實現(xian)管網水(shui)(shui)(shui)壓(ya)的閉環(huan)調節(PID)，使(shi)供(gong)(gong)(gong)(gong)水(shui)(shui)(shui)系統自動恒(heng)定(ding)穩定(ding)在設(she)(she)(she)(she)定(ding)壓(ya)力(li)值(zhi):即(ji)用(yong)水(shui)(shui)(shui)量增(zeng)(zeng)(zeng)加(jia)(jia)時，頻率增(zeng)(zeng)(zeng)加(jia)(jia)，泵(beng)速增(zeng)(zeng)(zeng)加(jia)(jia)，供(gong)(gong)(gong)(gong)水(shui)(shui)(shui)量相應(ying)增(zeng)(zeng)(zeng)加(jia)(jia)；用(yong)水(shui)(shui)(shui)量減(jian)少(shao)時，頻率降低，泵(beng)速減(jian)慢(man)，供(gong)(gong)(gong)(gong)水(shui)(shui)(shui)量相應(ying)減(jian)少(shao)，從而保(bao)證供(gong)(gong)(gong)(gong)水(shui)(shui)(shui)效率。滿足用(yong)戶(hu)對(dui)水(shui)(shui)(shui)壓(ya)和(he)水(shui)(shui)(shui)量的要求，同時達到(dao)提高(gao)供(gong)(gong)(gong)(gong)水(shui)(shui)(shui)質量和(he)效率的目的。該設(she)(she)(she)(she)備無需建造高(gao)位(wei)水(shui)(shui)(shui)箱和(he)水(shui)(shui)(shui)塔，水(shui)(shui)(shui)質無二次污染(ran)。是理想的現(xian)代建筑給(gei)水(shui)(shui)(shui)設(she)(she)(she)(she)備。
