| 摘 要： | 通过变频调速机泵节电率 ξ和静压头增量Δp/γ与位头增量ΔZ之和即 (Δp/γ +ΔZ)工艺参数之间关系的理论上分析表明 ,(Δp/γ +ΔZ)值的大小对于变频器的节电率 ξ起着决定性的影响 ,节电率 ξ随着该值的下降而提高 ,对于该值趋于零的泵节电效果最佳。

| Abstract: | Theoretical analysis on relation between electricity saving percent of frequency governing motors and pumps and the sum(Δp/γ+ΔZ) of static pressure increment Δp/γ and potential pressure increment ΔZ showed that,the electricity-saving percent ξ is mainly depended on the value of Δp/γ+ΔZ.ξ value increases with the decrease of (Δp/γ+ΔZ).Thus the pump with a value of (Δp/γ+ΔZ) near zero has the optimal electricity conservation. |
