| 摘 要： | 在引黄入晋工程部分管段水工模型试验研究基础上，通过数值计算得到了泵组的瞬变工况，其特性与初始流量和调节幅度有关。泵组瞬变工况对全系统流动都会产生影响。系统中设置调压塔可以调蓄瞬变流量和阻尼瞬变压力水头。此成果可为类似的设计研究和计算提供一个范例。

| Abstract: | On the basis of hydraulic model experiments of part pipeline in divert water engineering from the Yellow River to the Shanxi Province, by means of numerical calculation, transient condition of pumps were obtained. Transient condition characters relate to initial flowrate and regulate rangeability. Transient condition of pumps have influence on flow in system. Surge tank in system can reservior transient flowrate and dampen out transient pressure head. This achievement provided an example for similar design research and calculation. |
