The Nominal Packing Cross-section of Bush Seal is a surface or shape exposed by making a straight cut through something, especially at right angles to an axis. It represents the cross-sectional area of the bush seal packing material.
The calculator uses the formula:
Where:
Explanation: The formula calculates the nominal packing cross-section based on the difference between the mean diameter of the conical spring and the inside diameter, multiplied by 2/3.
Details: Accurate calculation of nominal packing cross-section is crucial for proper seal design, ensuring effective sealing performance, and preventing leakage in mechanical systems.
Tips: Enter mean diameter of conical spring and inside diameter in meters. Both values must be positive numbers, and the mean diameter should be greater than the inside diameter for valid results.
Q1: What units should be used for input values?
A: The calculator expects input values in meters (m) for both mean diameter and inside diameter.
Q2: Why is the formula multiplied by 2/3?
A: The 2/3 factor is an empirical coefficient that accounts for the specific geometry and packing characteristics of bush seals.
Q3: What is the typical range of values for nominal packing cross-section?
A: The values vary depending on application, but typically range from a few millimeters to several centimeters in industrial applications.
Q4: Can this calculator be used for different types of seals?
A: This specific formula is designed for bush seals. Other seal types may require different calculation methods.
Q5: How accurate is this calculation method?
A: The formula provides a nominal value suitable for initial design purposes. For critical applications, experimental validation is recommended.
