对某电站锅炉给水系统压力脉动的来源和特性进行了现场调查。通过系统设备消除，得出了锅炉给水泵旋转失速引起的振荡，因为它进入与管道回路的共振。对谐波条件下的等效线性系统进行了分析。分析模型提供了合理的协议与三个测试管道配置的意见。提供了一些见解的脉动和典型组件设备的动态阻抗的机制。
A field investigation was made to determine the source and character of pressure pulsations in the boiler feed system of a central power station. By systematic equipment elimination, it was concluded that the oscillation are caused by rotating stall in the boiler feed pump as it enters into resonance with the piping circuit. An analysis is carried out of the equivalent linear system under harmonic conditions. The analytical model provides reasonable agreement with the observations for the three tested piping configurations. Some insight is provided in the mechanism of the pulsations and the dynamic impedances of typical component equipment.
