摘　　要：结合有压给水管道不同运行工况气水两相流的特点,对管道中气囊运动引起的升压机理进行了理论分析,结合实际工程案例分析了气囊运动产生的危害,并提出了各种不同工况的最佳防护方式以及预防压力波动方案。According to the characteristics of two phase flow transient of the pressure water supply pipe under different operating conditions, the pressure rising mechanism incurred by air pocket motion in pipe was analyzed theoretically. The hazard of air pocket motion was discussed based on the practical project cases, and the best protection of pipe from water hammer under different operating conditions and the prevention against pressure fluctuation were proposed.

关 键 词：气囊运动 升压机理 断流弥合水锤
