应用瞬变流的基本理论 ,建立了用于大型轴流泵站水力过渡过程计算的数学模型 ,提出了泵站出口闸门在超驼峰运行条件下满足安全所要求的启闭规律。同时 ,根据计算结果 ,研制了蓄能式液压闸门系统 ,运行实践表明 ,该系统可有效地防止泵站开机过程中可能出现的水锤事故 ,并能实现泵站在超驼峰情况下 ,出现事故停电等紧急状态时闸门的可靠断流。 Based on the basic theory of transient flow, a mathematical model for calculating the hydraulic transient process of a large axial-flow pump station was established. The law of opening and closing required by the outlet gate of the pump station to meet the safety requirement under the condition of overturning peak was proposed. At the same time, according to the calculation result, the accumulator hydraulic gate system was developed. The practice shows that the system can effectively prevent water hammer accidents that may occur in the startup process of the pump station, and can also cause an accident Power outages and other emergency gates reliable cut-off.
