Embodiment Construction

[0012] refer to figure 1 , on the integral pump body (1), the passive pump mounting screw hole (2) is designed. Use the mounting screw hole (2) of the passive pump to connect to another radial piston pump of the same specification or a smaller specification to meet the large flow requirements of the overall oil supply. At the same time, the output pressure and flow of the two pumps can be adjusted separately to adapt to the The different working conditions of the whole system, combined with the improvement of the transmission shaft and the distribution shaft, can realize the double pump co-drive, and adapt to the graded oil supply and pressure adjustment requirements of the complex hydraulic system of the large radial piston pump. At the same time, the installation space is reduced, Save power.

[0013] The improvement of the pump body in cooperation with the drive shaft and the distribution shaft can realize double-pump co-drive.

[0014] When working, the hydraulic oil ent...

Abstract

The invention discloses a novel pump body of large sized radial variable plunger pumps. In the integrally-formed pump body, passive pump installation screw holes are provided. The novel pump body takes the place of conventional design structure, the novel structure of the pump body is easy to manufacture and is low in cost, related connections and matching parts are standardly designed. A radial variable plunger pump consisting of the novel pump body provided by the invention and other components can realize double pump driving, stepped regulation, separate regulation of pressure, flow and variable manner according to different system requirements; and installation space is saved. Power can be saved to the utmost extent according to different requirements.

Description

Technical field [0001] The invention relates to a pump body, a structural part of a power element of a hydraulic transmission, in particular to a new type of pump body of a large radially variable plunger pump. Background technique [0002] At present, the traditional radial piston pump has complex structure, difficult processing, limited by processing conditions, difficult promotion, unstable performance, and easy leakage. Or the flow rate is too small to meet the working conditions of the large flow system. Contents of the invention [0003] The problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a new pump body of a large radial variable piston pump. The part is made of nodular cast iron as the main material, and has undergone special heat treatment, which has strong wear resistance, simple structure, high pressure resistance, and no leakage. [0004] The technical solution adopted by the present invention to solv...
