What does a surge prevention curve diagram mean, and what are the names of the specific coordinate axes?
The image should be uploaded to facilitate discussion; it’s easier to talk when looking at the picture. Who knows whether you mean X Y or something else?
Is the anti-surge curve mentioned by the poster the compressor performance curve? The horizontal axis represents flow rate, while the vertical axis represents pressure. The stall point of the centrifugal compressor is indicated on the curve; different stall points exist for various rotation speeds or IGV opening degrees. All these stall points, when connected by lines, form the anti-surge line. As long as the compressor operates to the right of this anti-surge line, it is functioning properly.
