Failure Diagnosis of Large Cooling Tower Fan Based on FFT and EMD Analysis Method

Abstract:

Large cooling tower fan mainly used in petroleum, chemical, electric power industry, carries industrial water circulating cooling function and its operational status directly affects the industrial production. The blades are the important parts of the fan. The modal analysis is used to find the distribution of blade vibration frequency, and then the acquisition and analysis of vibration parameters of running large cooling tower fan blades are done using the EMD methods. Finally, compare with the modal analysis to find out safety hazards of fan blades. This method can eliminate the failures of the cooling tower fan blades, shorten the repair cycle, ensure the smooth production of the enterprise and improve economic efficiency.
