Lm. Lou et al., ELASTOHYDRODYNAMIC ANALYSIS OF THE SEALING PERFORMANCE OF ROTARY SHAFT HELIX LIP SEALS - PART 1, Journal of tribology, 120(3), 1998, pp. 476-481
Based upon EHD theory, the sealing performance of a rotary shaft helix
lip seal has been analyzed numerically using a complete hydrodynamic
lubrication model. In order to verify the analytical method, several e
xperiments are carried out under different operating.conditions. After
verification by the experimental results, the analytical method is us
ed to calculate the sealing limit and the optimum seal radial load. Th
e effects of the boundary pressure of sump side upon the pumping rate
of a seal are discussed.
