Analysis and Treatment of Excessive Swinging of the Upper Guide Bearing in Liushuping Hydropower Station
In Liushuping Hydropower Station,excessive swinging of the upper guide bearing is observed in the No.1 u-nit.In-depth inspection and analysis of the generator show that the problem is caused by the wear of the spherical pillars of the upper and the lower guide bearings,which causes excessive clearance between them and the deviation of the unit axis from the design range during operation.The spherical pillars of the upper and the lower guide bearings are re-pro-cessed and replaced,and reasonable clearance of the guide bearings is allocated.Stability tests of the unit after treatment show that all operation data meet the specification requirement.
