1. What is Pneumatic Cylinder Stroke Speed?

Definition: This calculator determines the speed at which a pneumatic cylinder extends or retracts based on air flow rate and piston area.

Purpose: It helps engineers and technicians optimize pneumatic system performance by calculating cylinder movement speed.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ v = \frac{Q}{A} \]

Where:

Explanation: The flow rate of compressed air divided by the piston's effective area gives the linear speed of the piston.

3. Importance of Stroke Speed Calculation

Details: Proper speed calculation ensures optimal cycle times, prevents damage from excessive speeds, and helps in selecting appropriate flow control valves.

4. Using the Calculator

Tips: Enter the air flow rate in m³/s and the piston area in m². For circular pistons, area = π × (diameter/2)². All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: How do I find the flow rate (Q)?
A: Flow rate can be calculated from compressor specifications or measured using flow meters in the pneumatic system.

Q2: What's a typical piston area?
A: Piston area varies by cylinder size. Common diameters range from 10mm to 200mm, with corresponding areas from 0.0000785 m² to 0.0314 m².

Q3: What affects stroke speed in real systems?
A: Factors include air pressure, tubing resistance, valve flow capacity, and load on the cylinder.

Q4: How can I control stroke speed?
A: Use flow control valves to adjust air flow rate entering or exiting the cylinder.

Q5: What's a typical stroke speed range?
A: Most industrial applications operate between 0.1-1.5 m/s, with high-speed applications reaching up to 3 m/s.
