Hangzhou Motor Turbine Technical Q&A
Thread Content
Is there anyone who has the manual for Hangzhou Steam Turbine machinery, or techniques for solving problems related to radial temperature vibration and displacement of turbine shafts? I would appreciate it if you could share this information. Thank you all :)
If the original poster runs into any problems, please share them so that everyone can be aware of them and discuss them. To be honest, the manuals for Hangzhou Steam Turbines are available if you search on forums; the manuals for back pressure and condensate gas that I have also came from downloads from forums in the past
While working, I observed the vibration curve of the turbine and noticed a periodic pattern in it. I forgot to take pictures, so I can only describe it verbally. I found that recently, there is a peak in vibration levels every hour on this curve; the vibration value increases significantly over a short period of time, going from around 9.0 μm to 20 μm, before dropping back to 9.0 μm. This peak variation lasts for about 5 minutes. The turbine at our facility has just been overhauled, and I’m not sure if anyone here can help resolve this issue (maybe my description isn’t clear enough; please forgive any misunderstandings)
I’m asking experts to recommend some materials on turbine engineering; I want to learn about its structure and auxiliary systems.
In this case, I’m afraid you won’t find much useful information in ordinary turbine manuals or bearing documentation. Personally, I suggest you take a look at materials on vibration and online monitoring. If it’s convenient, please upload a few photos showing the trends later.
Please make use of the search function on the forum – there’s a ton of such information available!
A similar situation can occur with steam fluctuations; verify whether the instrument data is accurate
This fluctuation cycle is neither long nor short~~ It is recommended to first check the fluctuations in steam pressure, as well as the load on the motor~~
