A lubrication test system for port plate pair of an axial piston pump was set up, and the composition and functions of the system was described. A mathematical model for lubrication film formation was established to illustrate lubricating film variation, and pressure and flow characteristics in the damping groove and pressure groove. The formations of lubricating film thickness were investigated and simulated under various working conditions. The film thickness will be reduced as the pressure and temperature increase, if other working conditions keep as constants.
