Design and Operation of a Device for Evaluating Shaft Seals in Dynamic Applications

Abstract

This document covers the design and operation of a testing device for evaluating elastomeric seals under dynamic conditions at temperatures ranging from 15 degrees to 300 degrees F. Turbojet engine fuel control systems employ sealing surfaces that move or slide over an elastomer sealing material. These seals are generally referred to as dynamic seals, and the usual configuration is an O-ring. Testing of seals under dynamic conditions is generally required to verify that seal materials are compatible with seals of varying composition. While this device is designed for testing dynamic seals that come in contact with liquid fuels, the device described herein can also be used for testing seals in the presence of other liquids and for applications other than turbojets.
