1. What is Cylinder Air Consumption?

Cylinder air consumption refers to the volume of compressed air required to operate a pneumatic cylinder per unit time. This calculation is essential for sizing compressors, air receivers, and determining overall system efficiency in pneumatic applications.

2. How Does the Calculator Work?

The calculator uses the standard air consumption formula:

\[ Consumption (L/min) = \pi \times \left(\frac{d}{2}\right)^2 \times Stroke \times Cycles/min \]

Where:

\( \pi \) — Mathematical constant (approximately 3.14159)
\( d \) — Bore diameter of the cylinder (mm)
\( Stroke \) — Length of cylinder travel (mm)
\( Cycles/min \) — Number of complete cycles per minute

Explanation: The formula calculates the volume of air displaced per cycle and multiplies by the number of cycles per minute to determine total air consumption.

3. Importance of Air Consumption Calculation

Details: Accurate air consumption calculation is crucial for proper compressor sizing, energy efficiency optimization, system design, and cost estimation in pneumatic automation systems.

4. Using the Calculator

Tips: Enter bore diameter in millimeters, stroke length in millimeters, and cycles per minute. All values must be positive numbers for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: Why is air consumption important for Festo cylinders?
A: Knowing air consumption helps in selecting appropriate compressors, filters, and dryers, and ensures optimal performance of Festo pneumatic systems.

Q2: Does this calculation account for air compression?
A: This calculation provides theoretical consumption at atmospheric pressure. Actual compressed air usage depends on operating pressure and system efficiency.

Q3: What factors affect actual air consumption?
A: Operating pressure, temperature, cylinder efficiency, leakage, and system pressure drops can affect actual consumption compared to theoretical values.

Q4: How do I convert the result to other units?
A: To convert L/min to CFM (cubic feet per minute), multiply by 0.0353. To convert to m³/h, multiply by 0.06.

Q5: Is this calculation valid for double-acting cylinders?
A: This calculation is for single-acting cylinders. For double-acting cylinders, multiply the result by 2 to account for both extension and retraction strokes.
