... and after optimization were compared. The results indicate that the width of the slide ring, the air side angle of the slide ring, the inner diameter of the slide ring, and the length of the internal pressure cavity are critical factors influencing sealing performance. Following optimization, the maximum...

.... Hydraulically controllable rod seals (HCRS) can be driven hydraulically to adjust the internal stress distribution of the seal to regulate the sealing performance. This may be an effective solution, although the leakage control mechanism and strategy remain unclear. This paper employs a thermoelastohydrodynamic...

..., the boundary fluctuation affects the pressure transfer and causes the sealing performance to deteriorate. The ferrofluid boundary obtained through the experiment is essential for an in-depth investigation into the rotary seal failure mechanism for improving the design of the ferrofluid rotary seal. 1...
