高壓泵電(dian)(dian)機系(xi)統節(jie)能(neng)(neng)是國(guo)家(jia)發改委(wei)啟動(dong)的十大重點節(jie)能(neng)(neng)工(gong)程(cheng)之一。國(guo)家(jia)發展(zhan)規(gui)劃要求，當前應推廣變(bian)頻(pin)調(diao)(diao)速節(jie)能(neng)(neng)技(ji)術，即(ji)風(feng)機、高(gao)(gao)壓泵、壓縮機等通用(yong)機械(xie)系(xi)統采(cai)用(yong)變(bian)頻(pin)調(diao)(diao)速節(jie)能(neng)(neng)措施，工(gong)業機械(xie)采(cai)用(yong)交流電(dian)(dian)動(dong)機變(bian)頻(pin)工(gong)藝調(diao)(diao)速技(ji)術。在(zai)"十一五(wu)"期間，我國(guo)將實現電(dian)(dian)機系(xi)統運行效率提(ti)高(gao)(gao)2個百分點，形(xing)成(cheng)年節(jie)電(dian)(dian)能(neng)(neng)力達200億千瓦時的目標。

業內專家(jia)介(jie)紹，我國(guo)高壓(ya)泵(beng)總(zong)(zong)裝(zhuang)(zhuang)機(ji)(ji)容量約5.8億千瓦，占(zhan)全國(guo)總(zong)(zong)耗電(dian)(dian)(dian)量的(de)(de)(de)60%～70%。其中(zhong)，交流電(dian)(dian)(dian)動(dong)機(ji)(ji)占(zhan)90%左右。專家(jia)分(fen)析，目前各類電(dian)(dian)(dian)機(ji)(ji)的(de)(de)(de)運(yun)行(xing)(xing)效(xiao)率(lv)加權平均(jun)比國(guo)外(wai)低(di)3～5個百分(fen)點，風機(ji)(ji)和泵(beng)的(de)(de)(de)效(xiao)率(lv)要比發達國(guo)家(jia)低(di)2%～3%，整體在用的(de)(de)(de)電(dian)(dian)(dian)機(ji)(ji)驅動(dong)系統(tong)運(yun)行(xing)(xing)效(xiao)率(lv)比國(guo)外(wai)低(di)近20%。如果按電(dian)(dian)(dian)動(dong)機(ji)(ji)總(zong)(zong)容量的(de)(de)(de) 10%進行(xing)(xing)調(diao)速改(gai)造(zao)，按年平均(jun)運(yun)行(xing)(xing)4000時、節(jie)電(dian)(dian)(dian)率(lv)20%～25%計算，年節(jie)電(dian)(dian)(dian)潛(qian)力(li)為(wei)320億～400億千瓦時。加上(shang)為(wei)改(gai)善工藝流程而(er)進行(xing)(xing)調(diao)速改(gai)造(zao)的(de)(de)(de)電(dian)(dian)(dian)動(dong)機(ji)(ji)可帶來(lai)的(de)(de)(de)節(jie)電(dian)(dian)(dian)潛(qian)力(li)，總(zong)(zong)節(jie)電(dian)(dian)(dian)潛(qian)力(li)約為(wei)500億千瓦時，相當于10000兆瓦裝(zhuang)(zhuang)機(ji)(ji)容量的(de)(de)(de)火力(li)發電(dian)(dian)(dian)廠的(de)(de)(de)年發電(dian)(dian)(dian)量。由此可見，電(dian)(dian)(dian)機(ji)(ji)系統(tong)節(jie)能(neng)是(shi)目前中(zhong)國(guo)節(jie)能(neng)市場上(shang)最(zui)具商(shang)業潛(qian)力(li)的(de)(de)(de)領域。
