本文讨论了需要考虑泵站附近用水的情况，并说明了如何使用管网模型来确定这些条件下的系统水头曲线。系统水头曲线可以通过在单个节点上整合水用户来改善，或者，对于更复杂的配水系统，可以通过使用配水模型来确定系统水头。包括7个参考文献、图表。

This article discusses cases in which water use near pump stations needs to be taken into consideration and illustrates how to use a pipe network model to determine a system head curve for those conditions. System head curves can be improved by consolidating water users at a single node, or, for more complex distribution systems, by using a water distribution model to determine system heads. Includes 7 references, figures.
