Abstract: Aiming
at the new characteristic of water hydraulic system, a kind of
hydrostatic bearing with a concentric gap damper is introduced.
The lubricative film thickness of the hydrostatic bearing
possesses inflexibility and the loading capacity is just
determined by the geometrical dimension of the piston-slipper
subassembly and has no relation with system pressure, viscosity
and temperature of water and speed of rotor. Theoretical
analyses and the verification of scheme done at the test rig
show that the hydrostatic bearing with a concentric gap damper
is especially fit for water hydraulic components.
Key words: Hydrostatic
