1. What is Pneumatic Cylinder Displacement?

Pneumatic cylinder displacement refers to the volume of air required to fill the cylinder chamber. It represents the theoretical air consumption for one complete cycle of the cylinder and is essential for proper pneumatic system design and compressor sizing.

2. How Does the Calculator Work?

The calculator uses the cylinder volume formula:

\[ Volume = \pi \times \left(\frac{Bore}{2}\right)^2 \times Stroke \]

Where:

\( \pi \) — Mathematical constant (approximately 3.14159)
\( Bore \) — Internal diameter of the cylinder (inches)
\( Stroke \) — Length of piston travel (inches)
\( Volume \) — Resulting cylinder volume (cubic inches)

Explanation: The formula calculates the volume of a cylinder using the cross-sectional area (π × radius²) multiplied by the stroke length.

3. Importance of Cylinder Volume Calculation

Details: Accurate cylinder volume calculation is crucial for determining air consumption, selecting appropriate compressors, sizing air receivers, and optimizing pneumatic system efficiency. It helps in cost estimation and energy consumption planning.

4. Using the Calculator

Tips: Enter bore diameter and stroke length in inches. Both values must be positive numbers. The calculator will compute the cylinder volume in cubic inches.

5. Frequently Asked Questions (FAQ)

Q1: What is the difference between bore and stroke?
A: Bore is the internal diameter of the cylinder, while stroke is the distance the piston travels from one end to the other.

Q2: How do I convert cubic inches to other units?
A: 1 cubic inch = 16.387 mL = 0.016387 liters = 0.0005787 cubic feet.

Q3: Does this calculation account for piston rod volume?
A: No, this calculates total cylinder volume. For actual air consumption, subtract piston rod volume for double-acting cylinders.

Q4: What is typical bore size range for pneumatic cylinders?
A: Common bore sizes range from 0.5 inches to 8 inches, depending on application and force requirements.

Q5: How does cylinder volume relate to air consumption?
A: Cylinder volume represents the theoretical maximum air consumption per cycle at atmospheric pressure. Actual consumption depends on operating pressure and cycle frequency.
