ABSTRACT Certain sticking phenomena generally exist in the common clearance sealing piston friction pairs. For oil media, it can be accepted because of its better lubrication, but for water media, it needs to be avoided as far as possible because of its worse lubrication. In this paper, the piston pairs with the hydrostatic bearing are presented to improve its anti‐sticking ability. The anti‐sticking performance is researched by computational fluid dynamics and experiment. The results indicate that the anti‐sticking ability can be improved for the new structure piston pairs. The key reason is that the hydrostatic bearing effect is reasonably applied. Copyright © 2012 John Wiley & Sons, Ltd.
