There is a peak in the temperature of the rear bearing shell of the turbine
Thread Content
Since some time ago, peak values have been observed in the temperature of the turbine’s rear bearing shells. However, these values have not reached the levels that would trigger a shutdown or an alarm. Let’s discuss what might be causing this phenomenon; the values are very irregular – they usually remain around 22 um, but at peak times they can reach up to 39 um. The alarm threshold is 75 um, while the shutdown threshold is 115 um. Although we’re still some distance away from a shutdown, I think these peak values keep rising. Please analyze the reasons behind this and suggest any possible solutions.
You are very diligent in monitoring the systems. If there is any change in just this one aspect, turn to the automation team to investigate it; if they can’t find the issue, then don’t let that person go home
Unit vibration problems are troublesome, especially with turbines.

Waiting, looking forward to everyone's analysis
Pay attention to whether the steam pressure rises suddenly in sync.
