大功率泵与鼓风机差动调速方案的设计

Design of Differential Speed Rugulation Proposals for High-powcr Pump and Blower

设计了一种大功率泵与鼓风机的差动调速方案，即由变频器控制的辅助电机的变速运动通过差动变速器与主电机驱动的恒定运动相合成，实现泵与风机的转速调节，此方案可达到显著的节能效果。

Desigmt a kind of differential speed regulation propOsal for high-power pump and blow-er.Variable motion of auxiliary motor controlled by frequency convertor is compounded with thecom,tant motion driven by main motor and differential governor so as to achieve the govelT1ment ofthe speed for the pump and blower.
