Rapid Diagnosis and Treatment of Whistling Vibration Fault After Installation of New Guide Vanes in Axial Flow Propeller Turbine
This article proposes a rapid diagnosis and treatment method for the whistling vibration fault that occurs after the installation of new guide vanes in axial flow propeller turbines.By comprehensively utilizing auditory examination,vibration measurement,visual inspec-tion,and fluid dynamics analysis,the main source of the fault was accurately identified.On this basis,there are shutdown,howling,and creep faults in the units of Yizhou Hydroelectric Power Plant after self operation.Through analysis,testing,and finite element calculation,the sealing meshing surface of the guide vane outlet has been modified,and the treatment effect is significant.The fault phenomenon has been effectively treated,and the operational stability and reliability of the water turbine have been improved.This study provides new ideas and methods for fault diagnosis and treatment of axial flow propeller water turbines,which is of great significance for ensuring the safe and stable operation of water turbines.
