Compressor stages
Thread Content
Why do some compressors have only one stage, while others have two or three stages? Please explain
It depends on the process requirements; if a high outlet pressure is required, more impellers will be needed
It is related to the process requirements; it depends on the final outlet pressure
The pressure ratio is generally kept below 3; an equal pressure ratio is not possible, as there are limits on the exhaust temperature. If a very high pressure were achieved in one step, the temperature would become too high. Compression takes place in stages, with cooling between each stage. To achieve as close as possible to isothermal compression. Doing it this way saves effort. But as the number of series and columns increases. Machines are also becoming increasingly complex. In short, the goal of everything is to do it in the most economical way possible!
What is a compressor with only one stage like?

At higher pressures, more stages can be added depending on the compression ratio (since the compression ratio per stage cannot be too high). When it is smaller, a few fewer stages can be used or just one stage can be used.
The 4th floor is correct. . . . . . . . .
