The Study of Hydrostatic Lubrication of the Slipper in a High-Pressure Plunger Pump

The lubrication condition between the slipper and the oblique plate of a high pressure pump affects its operating life. One of the studies in this paper is to analyze the oil film pressure distribution and load characteristics, considering the pressure-viscosity effect of the lubricant and the pressure-elasticity effect of the lubricating surface. In addition, a laser holographic photoelastic experimental verification is proposed. Another aspect of the study concerns the investigation of the dynamic stiffness properties of the oil film and its experimental verification. The conclusions obtained here provide a new theoretical basis for the design and parameter selection of a J high pressure plunger pump.
