Experimental testing on the influence of shaft rotary lip seal misalignment for a marine hydro-kinetic turbine

Tidal energy has received considerable attention over the past decade due to its predictability and high power density. The research in tidal turbine area concentrated primarily on improvement of conversion efficiency. In contrast, testing turbine’s mechanical components less attention. particular, reliable operation rotary seals is crucial prevent water ingress into electrical components. This paper outlines an experimental test campaign investigate effect shaft misalignment. Both instantaneous temperature pressure measurements were recorded from two seals. It was shown inside aligned seal increased until chamber became equal with inlet pressure. wear lip rings examined difference found be between 3.28% 19.61%. Inspection liners, showed presence strong wiping effects for misaligned maximum track width differences 52.94% 97.60% being noted. liner experienced wider tracks but not as deep 37.55% 103.13% recorded.
