The shaft displacement of Hangzhou Steam Turbine is high
Thread Content
The turbine is a extraction-type steam turbine; it operates in full condensing mode at the initial stage, with the shaft displacement increasing gradually； Random selection will be used later; the displacement remains stable for about 2-3 months ； It’s rising slowly again; I’m asking the experts here to analyze the reasons.
An average of 0.001 mm per day
It seems that the axial force has increased; the cause needs to be investigated. Has the lubricant been sent for testing? Check for metal particles as well.
The lubricating oil tested in the initial stages was of Qualified quality; there were no significant changes in the turbine load, and an increase in the amount of steam extracted from the intermediate stage would result in a slight decrease in displacement
