由電力拖動原理可知，風(fēng)機和水泵類負載屬平方轉(zhuǎn)矩負載:即電動機軸上的轉(zhuǎn)矩與其轉(zhuǎn)速的平方成正比[即]。按照流體機械的相似規(guī)律，當(dāng)風(fēng)機的靜壓等于零或水泵的靜揚程等于零時，風(fēng)機與水泵的流量與轉(zhuǎn)速成正比，其出口壓強與轉(zhuǎn)速的平方成正比，而電動機軸功率則與轉(zhuǎn)速的立方成正比:
如果流量下降到額定流量的80%，電動機軸功率將下降到額定值的51.2%;如果流量下降到額定流量的60%，則軸功率將下降到額定值的21.6%。即使考慮到調(diào)速裝置本身的損耗等因素，其節(jié)電效果也是十分可觀的?？梢婏L(fēng)機、水泵采用調(diào)速驅(qū)動是一種非常有效的節(jié)能方式，因為大多數(shù)風(fēng)機和水泵都需要根據(jù)發(fā)電機組負荷的變化調(diào)節(jié)流量，對于調(diào)峰機組則尤其如此。為這類機組配套的各類風(fēng)機、水泵均應(yīng)采用調(diào)速驅(qū)動，以獲得最佳節(jié)能效果。經(jīng)試驗證明，對于風(fēng)機和水泵類負載，采用轉(zhuǎn)速調(diào)節(jié)可以節(jié)電20%~50%。因此可以看出采用高壓變頻器能夠達到非常良好的節(jié)能效果。
