Small turbine in compressor oil station
Thread Content
Does anyone familiar with compressor oil station small turbines know something about their structure and the principle of speed control? Specifically, how does the manual speed control mechanism work, and how does the overspeed protection function? Please advise; thanks in advance
Please upload pictures of the small turbine and governor before I can give you my opinion.
It seems that the small turbine in the oil system of the AC press I was previously exposed to didn’t have a speed regulator; instead, the speed was controlled by opening the steam inlet valve: lol. Later, we removed it and replaced it with a motor
What was taken apart to replace with a motor?
Relatively speaking, small turbines are certainly not as convenient as motors; nowadays, many large-scale units no longer use small turbines for their lubrication pump systems, opting instead to use two motors for drive. However, the advantage of small turbines is that they are not constrained by the power supply and can continue to operate even in case of a power outage ； Small back-pressure steam turbines are equipped with high-level oil tanks, while large condensing steam turbines have emergency DC motors
I’ve never seen an oil pump at a gas station powered by a steam turbine~~ Hehe~~ Could you share photos of the site and the control system? It would be great if there are also schematic diagrams~~ Hehe~~
Ordinary small turbine steam engines can handle this; for special models, there are PG-PL types of governors as well as TG types, and most of these governors are from Woodward in the United States
