| 摘 要： | 本文采用特征线法对机场管道加油过程中常见的阀门关闭、输油泵动力故障等水力瞬变工况进行了数值模拟仿真。综合评价了影响水击压力峰值大小的各种因素,相对于管道长度、油品粘度等因素而言,阀门的本身特性及其调节规律影响水击压力峰值大小的主要因素,从而为采取相应的水击防护措施提供理论依据。

| Abstract: | The characteristic line method is adopted to simulate the hydraulic transient of the common valve closing an d oil pump power failure numerically in the pipeline refueling process of the airport. Comprehensive evaluation is made to the influencing factors on the water hammer pressure peak. Relative to the pipe length,oil viscosity and other factors ,the characteristics of valve itself and its regulation law influence the main factors of the water hammer pressure peak ,so water hammer protection measures should be taken so as to provide theoretical basis . |
