Compressor anti-surge control
Thread Content
How are the anti-surge control points for centrifugal compressors calculated? What do the horizontal axis PS and the vertical axis HS represent, and how are they calculated? What calculations or parameters determine the anti-surge point? I seek help from all the experts. . .
The anti-surge line should be determined by the manufacturer through experiments.
Generally, it is provided by the compressor manufacturer~~~~ It is related to your design
Well, what was said upstairs is correct – the anti-surge curve for the compressors in our company was developed by the manufacturer itself :)
Generally, more than two surge points are measured on-site, and then, through calculations, a system is implemented to prevent surging. For this purpose, either flow rate is used as the horizontal axis and outlet pressure as the vertical axis, or flow rate is used as the horizontal axis and the pressure ratio between the inlet and outlet as the vertical axis; of course, there are other formats as well. In cases where a motor serves as the driving force, it is possible to use current as the horizontal axis~~
