Air Consumption
Calculating Air Consumption
Find the air consumption of pilot air for operation with a 4 Hz switching cycle and pilot air pressure of
0.4 MPa from the air consumption graph.
Selection procedures:
1. Look up from the 4 Hz switching cycle to find the intersection with SUP = 0.4 MPa.
2. From the point just found, draw a line to the Y-axis to find the air consumption. The result is
approximately 230 L/min (ANR).
Caution
1. The air consumption differs greatly depending on properties (viscosity,specific gravity) of the fluid
being transferred and operating
conditions (density, lifting range, transfer distance).
