Experimentation Study Of Fan State Monitoring In Power Plant

There are two sessions in this research. In the first session the fans vibration on-line monitoring system is realized with VC language, also compile auto power spectrum density function, cross power spectrum density function, autocorrelation function and cross correlation function etc spectral analysis function to carry through simple offline fault diagnosis. Fan familiar fault types are summarized and fans failure mechanism is researched. Based on fans fault system analysis, imbalance and unalignment two fault is carried out on GB4-73No.8D test-bed. Vibration test is carried out on vary rotate speed diffuser coupling and throttle. Data file is analyzed by Matlab function, then effect of imbalance and unalignment according to vary factor is found. Wang Dayong(Power Plant Thermal Power Engineering) Directed by prof.
