Output force of a pneumatic cylinder is function of air pressure as cylinder speed is function of its air flow. This gives the SCFM air consumption for this application. Most rotameters read in SCFM when you may be expecting ACFM flow. The pneumatic cylinder stroke is the phase during which the piston travels from the minimum extended length to the maximum extended length position or vice versa. First, we must gather some basic information about your pneumatic cylinder so we can calculate the air consumption: The formula for the air consumption of a single-acting. As an example, assume a sphere is moving through the air at sea level with a velocity of 100 m/s. Air consumption is a function of the volume of a cylinder, the cycle time, and the inlet air pressure. In single-acting cylinders, Au = (/4) D. The force calculation of an air cylinder depends on the pressure inside the cylinder, the piston diameter, the friction force generated by the seal components, and the spring force (in the case of single-acting devices). cylinder is as follows: A = Piston Area (Square Inches) S = Stroke (Inches) C = Cycles per Minute CFM (Cubic Feet per Minute) = (A x S x C) / 1728 Keep in mind that dwell times and cylinder sequence can affect the results when using this formula. 2023 Womack Machine Supply Co.
