Would exhaust diffuser leakage have an impact on N2 bearing vibrations? If so, why?
Searching,
Yes. Heat causes expansion, and expansion of a bearing housing can cause alignment changes, which can lead to vibration.
In the future when posting to control.com, please provide as much information as you can about the turbine and auxiliary equipment involved as you can. While this question is fairly generic in nature, it would have been nice to know more about the turbine at your site.
Providing as much information as you can in your original post--including any troubleshooting you have done, as well as the <b>results</b> of the troubleshooting (actionable data) will prevent respondents from asking numerous questions, and you from telling us, "We've already tried that," and being unhappy with the responses you get from control.com. The more information you can provide the better and more concise the responses you will get--and faster, too.
