【摘要】 通过分析空气罐和空气阀的运行特点,建立了长距离有压输水工程水力过渡过程仿真模型。结合实际工程,采用该模型开展了输水系统在事故停泵、水泵启动和关闭等多种工况下的水锤压力分布规律研究。根据分析结果给出了相应的运行建议,为输水工程建设提供了数据支持。更多还原

【Abstract】 Through analyzing operation characteristics of air vessel and air valve,this paper built the simulation model hydraulic transient process of long distance water transfer projects. Combined real project, it used the model to study the distribution law of water hammer of long distance water transfer system in many work conditions of stopping pump by accident,starting and closing pump. According to the simulation results,the paper put forward some operation suggestions which could provide data support for the construction of water transfer project.更多还原
