Axial piston pump is the core power component of hydraulic system,which plays an important role in hy-draulic control system.The lubrication and friction characteristics of the three friction pairs in axial piston pump af-fect the performance and service life of the piston pump itself.The research on the theory and technology of three friction pairs of axial piston pump is of great significance for improving the performance and reliability of axial pis-ton pump.In this paper,the lubrication theory of three friction pairs and the theory and technology of friction char-acteristics of axial plunger are reviewed,and the surface modification technology to improve the performance of fric-tion pairs is also discussed.
