Treatments of the large vibration problem of primary air fan for Hubei Xiangyang Power Plant

Abstract

Abstract:

Taking the large vibration problem of primary air fan for Hubei Xiangyang Power Plant as an example, and facing the situation of its complicated reasons, including the bearing wear and unbalance, this paper found the failure bearing accurately using the EA expert system and replaced it. After that, the large horizontal vibration problem still existed. Then a further analysis was conducted and a dynamic balance treatment was dealt with, At last, the large vibration problem of primary air fan was solved completely.

Key words:

primary air fan, bearing, vibration, drive end, free end, horizontal vibration, exciting force, unbalance
