1. What is Hydraulic Cylinder Load Calculation?

Definition: This calculator determines the force generated by a hydraulic cylinder based on system pressure and piston area.

Purpose: It helps engineers and technicians design and analyze hydraulic systems by calculating the output force of cylinders.

2. How Does the Calculator Work?

The calculator uses the fundamental hydraulic formula:

Where:

• \( F \) — Force (Newtons, N)
• \( P \) — Pressure (Pascals, Pa)
• \( A \) — Piston area (square meters, m²)

Explanation: The hydraulic pressure acting on the piston area generates a linear force that can push or pull loads.

3. Importance of Hydraulic Load Calculation

Details: Accurate force calculation ensures proper cylinder selection, system safety, and efficient operation of hydraulic machinery.

4. Using the Calculator

Tips: Enter the system pressure in Pascals and the piston area in square meters. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: How do I find the piston area?
A: For circular pistons, use \( A = \pi \times r^2 \) where r is the piston radius. For non-circular pistons, calculate the cross-sectional area.

Q2: What's a typical hydraulic system pressure?
A: Common industrial systems operate between 6.9-34.5 MPa (1000-5000 psi), but always check your specific system specifications.

Q3: Can I use different units?
A: This calculator uses SI units. For imperial units (psi, in², lbf), you'll need to convert or use a different calculator.

Q4: Does this account for friction losses?
A: No, this is theoretical force. Actual force may be 5-15% less due to friction in seals and mechanical components.

Q5: How does rod area affect calculations?
A: For retraction force (pulling), use the annulus area (piston area minus rod area) in your calculation.
