Information on turbine control oil

Under normal circumstances, the lubricating oil and control oil used in turbines are the same

I wonder if your unit is of the back-pressure type? Condensation type? Or is it a condensation extraction type? The specific control systems have certain differences in their schematic diagrams. Regarding the regulation of steam turbines, there are some posts on the forum that might contain what you’re looking for: http://bbs.hcbbs.com/search.php?searchid=3548&orderby=lastpost&ascdesc=desc&searchsubmit=yes. The question asked in the first post is likely about the diagram of the control oil system; surely the lubricating oil and control oil/sealing oil used in the same turbine unit are of the same type, right? Is it necessary to have another separate oil supply system? The difference is that the control oil is drawn directly from the outlet of the lubricating oil pump, without passing through an oil cooler; it serves only to provide hydraulic power.

We have everything of that kind, but some of the devices are too large, so we haven’t even taken a look at them. All of the turbines we operate are back-pressure type; some of them have exhaust systems, and they are all industrially driven. The factory also has turbines used for power generation, but I haven’t seen them

The pressure of the control oil is generally higher than that of the lubricating oil. Both originate from the lubricating oil pump; the control oil is formed by regulating its pressure, while the lubricating oil is produced by reducing the pressure of the control oil.

Power plant steam turbines usually have a separate high-pressure EH oil system, with a pressure much higher than that of the lubricating oil; you might want to learn more about the DEH control system

It’s hard to say. I have the drawings, but not in electronic format. What do you want to ask? I can tell you about it.

Ask away; we have it here, and I’ve also done some preliminary research on it

It would be great to have electronic materials on this topic!

There are no specific details regarding the issue, such as what type of unit it is, etc., haha

Specifically which compressor, as the pressures are different. There’s too much to say. Apply it to similar situations.
