In the compressor performance curve provided by the manufacturer, “flange head, flange Eff” – what does “flange” refer to?
Thread Content
Hello everyone: The normal compressor performance curve includes head, efficiency, power, etc. The compressor performance curves provided by a current colleague from Elliott include the word “flange” before values related to head pressure, efficiency, and flow rate. I wonder if this term has any special meaning? Are they the curves for head pressure, efficiency, power, etc., as is commonly referred to? (An example is shown in the figure below.) Please advise.
Haven’t encountered it – does it refer to the pressure and flow at the outlet flange built into the equipment? Because the pressure and flow rate can vary at each location, this is used to refer specifically to one particular place
It indicates the measurement location and the gas characteristic parameters at that site.
“A flange” is also added in front of efficiency and power; it is a single-stage compressor.
