A Method of Comparing Recurring Observations of Leakage in Rotary Shaft Seals under Accelerated Tests

Accelerated testing of rotary shaft seals, coupled with advanced methods of measuring and recording leakage, is challenging existing notions of zero-leakage evaluations of time-to-failure and rotary shaft seal comparisons.

This paper will explore a possible method of comparing and evaluating recurring observations of leakage in rotary shaft seals, as an integrated part of a hydraulic system, under accelerated tests.

In extension of this endeavor, the Author is open to future collaboration with any individual wishing to pursue either: a more rigorous mathematical examination of the assumptions made in this paper; or an effort to implement the Leakage, Number of Motor and Time parameters into the 3D surface roughness integrals which were discussed in this paper.
