Abstract

Faults like unbalance, mechanical looseness, misalignment, bearing fault and bent shaft etc. causes vibration in rotating machinery. Detection of these faults in machines is required to avoid serious and significant economic losses. In this paper, mainly concentrated on the implementation of vibration based maintenance on forced draft fan in sugar factory. Order analysis technique is used for fault diagnosis of forced draft fan. In order analysis technique, both amplitude and phase are obtained. The results show that the faults in the forced draft fan, such as unbalance, looseness and bent shaft are effectively identified. It can detect faults effectively and precisely before the failure occurs.
