以实际工程案例为对象,对设有均压管的分布式变频系统的典型换热站分布泵运行调节过程进行分析。利用ORIGIN拟合出分布泵泵频与二次供温曲线的函数关系,为分布泵的泵频输入提供指导。研究结果为分布泵系统定零压差点运行调节方式提供有价值的理论指导。近年来我国城市化发展速度加快,百万人口以上规模的城市不断增多,这极大促进我国集中供热事业的发展。狄洪发等人指出在部分负荷工况下,分布式变频调节系统比电动调节阀更加节能;石兆
Taking the actual project as an example, this paper analyzes the process of regulating the operation of a typical heat transfer station distributed pump in a distributed frequency conversion system with pressure equalizer. Using ORIGIN to fit the distribution pump pump frequency and the secondary heating curve as a function of the distributed pump pump frequency input guidance. The research results provide valuable theoretical guidance for the regulation of zero pressure drop in distributed pump system. In recent years, China’s urbanization has accelerated, and the number of cities with a population over one million has been increasing. This has greatly promoted the development of centralized heating in China.
