Regarding the turbine speed control system
Thread Content
In my opinion, the diagrams of turbine speed control systems are basically all the same. The legend is incomplete; I don’t recognize many of the symbols. It’s like written in a secret language; it’s unreadable. If anyone understands, please explain what those things are.
I’ve seen many diagrams of speed control systems, and they all look more or less the same; in any case, I can’t understand them – they’re like unreadable code. The legends on the right side are incomplete and don’t help at all in understanding the diagrams.
To understand the process, one only needs to be aware of the start-up oil speed, shutdown oil pressure, working oil, and secondary oil. The legend here is quite comprehensive; is there a component that you don’t recognize?
I basically don’t know them; they’re not in the legend, I don’t recognize them. For example: Point P, Point T, Point E, Points H1/H2, Point C, Point G2, Point T, and so on. What are these? 2225, 2227, 2050, 2030, 1845, 2226, 2040, 1742, 5600, and so on – what are these? Could you provide a detailed introduction? Thank you.
2225, 2227, 2050, 2030, 1845, 2226 are the codes for system components, which can be found in the detailed list. Points P, T, E, H1/H2, C, G2, and T – are these the interface codes?
Hehe, this is a bit difficult; the explanation isn’t very clear.
This has also been my confusion all along
