沿江取水泵站停泵水锤防护措施比较

Comparative Research on Protective Measures of Pump-stopping Water Hammer in Water Intake Pumping Station along River

对沿江取水泵站停泵水锤的特点进行了分析,阐述了3种水锤防护措施即空气阀、空气罐和单向调压塔的原理及边界条件的数学模型,并结合具体实例,应用特征线法对不同防护措施的防护效果进行了数值模拟比较分析。

The feature of pump-stopping water hammer in water intake pumping station along river was analyzed and the protective measures and the mathematical models of three protective measures of air valve, air vessel and one-way surge tank, as well as their boundary conditions, were conducted. Combining with an actual engineering example, the protective effects of various measures were compared through numerical simulation with the character-line method.
