关于某大型环状热网设中继泵的分析研究

以某大型环状热网为分析对象,采用环形管网水力计算方法,对改、扩建的环网工程作设计工况下的校核计算,调整部分不合理管段,绘制了水压图,指出设置中继泵的必要性;在此基础上,重点分析环状热网中继泵的设置原则,包括位置的选取范围和与循环泵的合理匹配等技术条件。通过分析,不仅为该环网工程中继泵的选型提供技术依据,而且对其他类似工程也具有普遍的借鉴意义。

Research on setting relay pump on a large-scale ring-shape heating network

Taking a large-scale ring-shape heating network as analysis object,the rebuilt and enlarged ring-shape network project for revising in design condition were calculated by adopting the hydraulic calculation method of ring-shape network.Partial improper pipes diameter were adjusted,its water pressure diagram were drawn,the necessity of setting relay pump was pointed out;the principle for setting pump in ring-shape heating network,including the scale of location and how to match circulation pump properly,were analyzed.The results not only offer some technological parameters for setting relay pump in this ring-shape network project but also make some reference for other familiar projects.
