基于水头因素影响的轴流转桨式水轮机振动分析

摘要

Vibration data of bearings in Kaplan turbine units in Gezhouba hydropower station are collected with the status monitoring system .The influence of different water heads on the vibration of large Kaplan turbine units is analyzed .Rec-ommendations are then given for the operation of large Kaplan turbine units .%利用葛洲坝水电站已建立起来的状态监测系统，采集不同水头下影响大型轴流转桨式机组各部轴承振动变化的数据，分析水头对机组振动的影响，提出今后改进大型轴流转桨式机组运行的建议。
