Description

technical field

[0001] The invention relates to an oil film testing experimental device for a plunger pair in a plunger pump, which belongs to the field of hydraulic component manufacturing. Background technique

[0002] The hydraulic system is widely used in the industrial field, and it has made great contributions to the automation, intelligence and performance improvement of equipment in the fields of construction machinery, equipment manufacturing, aerospace and other fields. The hydraulic pump plays an important role as the energy source of this hydraulic system. Axial piston pumps have high pressure, high volumetric efficiency, easy flow adjustment, and because of their relatively good sealing effect, they are suitable for high-pressure and high-power hydraulic systems and are widely used in engineering practice.

[0003] Traditional plunger pump designs use empirical methods, approximate formulas, etc., and are based on static parameters. In the later stage, the des...
