Calculating Air Consumption
Required specifications example:
Find the pilot air consumption for a discharge rate of 6 L/min, a cycle of 4 Hz and a pilot air pressure
of 0.25 MPa.
Selection procedures:
1. In the graph for air consumption (4 Hz), start at a discharge rate of 6 L/min.
2. Mark where this point intersects with the air consumption rate. Based on the proportional
relationship between these lines, the intersection point will be between the discharge curves SUP
= 0.2 MPa and SUP = 0.3 MPa.
3. From the point just found, draw a line to the Y-axis to find the air consumption. The result is
approximately 70 L/min (ANR).
