摘　　要：通过分析两类典型工况下管网曲线与风机曲线的变化规律,阐明了风机调速节能的计算方法。同时指出,在分析除尘风机调速运行时,要考虑粉尘不沉降情况下管道的最低风速限制。在系统设计时还应考虑变工况除尘点在系统的位置,以尽可能减少系统再平衡的工作量。By analyzing the variation law of ductwork curve and fan curve under two typical working conditions, the calculation method of energy saving of fan speed control is clarified. At the same time, the minimum velocity limit in case dust is not settling should be concerned when analyzing control operation of the fan speed. In the design of the system, it is necessary to consider the location of the variable working condition dust removal points in the system to minimize the work of system rebalancing.
