Abstract

Abstract: The guide blades of one axial fan with combined static and dynamic adjustment have been cracked up repeatedly due to heavy vibrations. Through assembly tests, gas exciting tests, hammer tests, reinforcement tests and characteristic analysis, the cause of fan vibration is figured out. By way of comprehensive tests, the problem of fan bearing vibration is eventually solved. In addition, the technical improvement measures and solution outlines for the fan casing vibration are proposed, which provides a reference for dealing with the same type of vibration problem.

Key words: axial fan, vibration characteristic, high frequency
