Abstract

The invention provides an oil film test experiment device of a plunger pair in a plunger pump and relates to the hydraulic element manufacturing field. The oil film test experiment device aims at solving the problem that plunger pairs in the existing plunger pumps are large in oil film parameter test difficulty. The oil film test experiment device comprises an inclined plate, a slipping boot, a plunger and an oil inlet pipe and also comprises a coupling, an abrasion-resistant plate, a plunger sleeve, a tensioning sleeve, a tensioning sleeve seat, a supporting frame, a connecting part, a rotating shaft and an arc-shaped sliding groove; the supporting frame comprises a connecting plate and a fixed base plate which are perpendicular to each other; the tensioning sleeve seat is fixed on the connecting plate of the supporting frame through bolts. The oil film test experiment device of the plunger pair in the plunger pump is applied to an oil film test experiment of the plunger pair in the plunger pump.

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...
