中比速可逆式水泵－水轮机的压力脉动特性

The Characteristics of Pressure Pulsation On a Medium Specific Speed Reversible Pump-Turbine

本文根据潘家口电站模型验收实验资料归纳出可逆式水泵－水轮机的压力脉动特性。文中给出水泵－水轮机在水轮机工况、水泵工况、制动工况、反泵工况的一系列压力脉动特性的实测曲线，同时也介绍了各种工况的脉动频率特征和分析意见。

By analyzing the data taken from the model accept test on a reversible pump-turbine,a series of cases of pressure pulsation on turbine,pump,brake and reverse pump performances has been carried out.The frequencies of pressre pulsation and the adequate conclusions of the characteristics of pressure pulsation on this pump-turbine heve been introduced.
