Centrifuge performance curve
Thread Content
What do the horizontal and vertical axes of this graph represent? This is a graph showing the machine in a stopped state; it shows the position of the ball when the machine is operating normally, and it shows the position of the ball when the centrifuge experiences surging.
Generally, the horizontal axis represents flow rate (or current), while the vertical axis represents pressure. The yellow curve is the anti-choke line, and the red curve is the choke line; during normal operation, the operating point lies to the right of the yellow curve
