Abstract

Abstract: The vibration problems of induced fans with two-stage adjustable rotor blades in a 300 MW power generation unit are described in details. By virtue of hot test, disassembly overhaul and onsite vibration test, the causes of vibrations are analyzed. By taking account of the observations during the vibration process, the data testing and the fault diagnosis all together, the culprit of vibration is figured out and corresponding solutions are proposed. Consequently, the root cause of vibration is eliminated fundamentally. The study result can provide reference for the retrofit and secure operation of axial fans with two-stage adjustable rotor blades in coal-fired generating units.

Key words: coal-fired power plant, fan, vibration, fault diagnosis
