摘　　要：水轮机压力脉动是影响机组稳定性的一个重要因素。本文以某比转速的灯泡式水轮机为研究对象,通过模型试验的方法,分别分析了转轮与转轮室间隙、空化系数、协联关系等因素对压力脉动的影响,为今后灯泡式水轮机的设计及原型机组的运行提供参考。The pressure fluctuation of turbine is an important factor influencing the stability of unit. In this paper, analysis is conducted for the influences of clearance between runner and runner chamber, cavitation coefficient and cam relationship on the pressure fluctuation by taking bulb turbines with given specific speed as the object of research through model test, to provide reference for the design of bulb turbine and the operation of prototype unit.
