摘　　要：指出了动力分布式二级泵供热系统的水力计算首先应该确定零压差点位置,然后再进行各环路的水力计算,最后利用其计算结果确定循环泵。从动力分布式供热系统与传统集中供热系统的差异出发,探讨了两者水力计算方法的不同,然后对动力分布式二级泵供热系统的水力计算步骤进行了详细完整的分析,以期为以后的动力分布式系统的工程设计提供参考。The hydraulic calculation of power distributed secondary pump heating system should first determine the zero--pressure close position, then conduct the hydraulic calculation of each loop, and finally determine each circulating pump from calculation results. This paper analyzed the hydraulic calculation method of two systems from the difference between power distributed heating system and traditional heating system, then calculation steps of power distributed two stage pump heating system are introduced in detail for providing reference for the future power distributed system engineering design.
