Abstract: In the traditional seawater hydraulic piston pumps, the inherent structure of the slippers made it susceptible to problems such as eccentric wear and slipper burning. A new integrated slipper was proposed to fundamentally eliminate the overturning problem of slippers caused by centrifugal forces and to reduce the lateral force on the pistons. The lubrication mathematical model of the integrated slipper/swashplate interface was established, and the influences of temperature and working condition parameters on the lubrication and energy consumption characteristics were analyzed. The results show that with the increase of medium temperature, the dynamic pressure effects of integrated slipper decreases, the water film thickness decreases, resulting in the decrease of leakage. And the viscosity decreases with the increase of temperature, the friction forces on the integrated slipper decrease, and the viscous friction power losses decrease. With the increase of working pressure, the water film thickness increases, the leakage increases, and on the contrary, the viscous friction power losses decrease. With the increase of the shaft speed, the volumetric power losses and viscous friction power losses of the integrated slipper/swashplate interface increase.
