Performance Curve shows the balance of Discharge Head and Water Discharge
[Exsample] How much is the discharge pressure where Air Supply Pressure is 0.5 MPa and Water discharge is 20 l/min?
The discharge pressure is the value on the vertical axis of Point: A. Point A is the intersection of the straight line, which crosses through the point 20 l/min on the horizontal axis, and the Air Supply Pressure curve value 0.5 Mpa.
Where you can accumulate the Air Consumption by the proportional distribution of Air Consumption curves which both sides of Point A.
Air Supply Pressure is given by the following formula.
{ 200 Nl + (300 Nl – 200 Nl) x CA / CD } ( Nl / min )
Nl (Normal Liter) means the air amount which is not compressed air amount but the transferred rate of atmospheric.
It shows the flow rate of air (litter per minute) under uncompressed, standard atmospheric pressure.
