Analysis on reason of larger vibration of bearing No.1 of 300MW steam turbine and treatment

Abstract

Abstract:

Abstract:Aiming at the larger vibration of bearing No.1 of the turbine in a company under high load, the shaft center adjustment and the shaft load distribution of the unit No.1 during its heatsupply reformation were analyzed, and the adjusting measures were formulated. Using the unit reformation opportunity, the similar problem of unit No.2 was treated too. The larger vibration of bearing No.1 of the units was solved, and safe operation of the units was ensured.

Key words: Key words:steam turbine, shaft vibration, steam flow perturbation, bearing neck uprising inclination
