Abstract

The invention discloses an axial-flow type hydraulic pump with double rows of radial plungers, wherein two rows of plunger groups are arrayed in the pump in parallel, the movements of the plunger groups are not affected by each other, and the space in the pump body is used in the maximum degree. According to the axial-flow type hydraulic pump with double rows of radial plungers, an eccentric shaft drives a star wheel to push the plungers to move, the transmission is realized through rolling friction, so that the axial-flow type hydraulic pump with double rows of radial plungers is simple and reliable; the total output of the pump is the sum of the output abilities of all the plunger groups, so that the delivery capacity is high; a plurality of cylinders work together, so that the output peak values of the cylinders are complementary, and the total flow fluctuation can be lowered obviously; the plungers and the plunger cylinder barrels are independent from the pump body, so that the axial-flow type hydraulic pump with double rows of radial plungers is simple to process, is low in cost, is convenient to assemble and maintain, and can be mounted and demounted quickly; the pump uses axial flow mode, the parts among the plungers, the star wheel, the eccentric shaft, an oil inlet and an oil outlet are sealed, so that the capacity utilization ratio is high.

Description

technical field [0001] The invention belongs to the technical field of radial plunger hydraulic pumps, in particular to a shaft-distribution double-row radial plunger hydraulic pump. Background technique [0002] As the core component of the hydraulic transmission system, the hydraulic pump is not only the source of power for the hydraulic system, but also the main link that generates leakage and noise. In order to improve the energy utilization rate of the system and reduce vibration, one of the most effective ways is to develop a hydraulic pump with high volumetric efficiency. , hydraulic pump with stable flow. Among all kinds of hydraulic pumps, radial plunger hydraulic pumps are widely used in various hydraulic systems for high-pressure operations, such as die-casting, injection molding, forging and oil extraction, due to their significant advantages of low wear, large displacement, and high volumetric efficiency. Wait. [0003] The traditional radial piston pump gener...
