What are the reasons for the temperature change of the thrust pad of a steam turbine? 2020-04-03


The reasons for the temperature change of the thrust pad of the steam turbine are:

 

⑴ The steam turbine load changes and the axial thrust changes.

 

⑵ After the steam turbine load is changed, the stress of the pads is uneven, and the temperature of individual pads changes.

 

⑶ Steam temperature is too low or water shock.

 

⑷ Vacuum drops more.

 

⑸ The blade is seriously fouled.

 

⑹ The amount of oil in the thrust bearing changes.

 

⑺ Thrust pad is worn or damaged.

 

⑻ Oil temperature change of oil cooler.

 

⑼ The thrust bearing itself is defective.
