Embodiment Construction
[0011] Depend on Figure 1 to Figure 3 It can be seen that the solution adopted by the present invention to solve the technical problem is to provide a new type of rotating structure of the disc flow radial variable piston pump. The inner ring 3 of the stroke of the rotating structure 1 is a pushing structure with a certain angle to the horizontal direction.
[0012] Depend on image 3 It can be seen that the end of the plunger 2 and the stroke inner ring 3 of the rotating structure 1 are installed at the same angle and are installed in the pump body in cooperation with each other.
[0013] When in use, the outer ring of the rotating structure is fixed in the rotor of the plunger pump to form a new rotating mechanism, which is assembled with the pump body, oil distribution plate, stator, rotor, plunger assembly, control valve seat, etc. to form a valve. A disc-distributed radial piston pump with core self-distributed servo structure. The hydraulic oil enters the pump body fr...

The invention relates to a novel rotating structure of a plate-flow-distribution radial variable-displacement plunger pump. Aiming at solving the problems that the existing rotating structure cannot be well matched with the plate-flow-distribution radial variable-displacement plunger pump, the wear is caused and the production cost is increased due to the limitation of the structure of the existing rotating structure, the invention provides the novel rotating structure of the plate-flow-distribution radial variable-displacement plunger pump. The stroke inner ring (3) of the rotating structure (1) is a pushing structure, wherein a certain angle is formed between the pushing structure and the horizontal direction. The novel rotating structure of the plate-flow-distribution radial variable-displacement plunger pump has the advantages that since the rotating structure has the pushing structure with the angle relative to the horizontal direction, the rotating structure can be well matched with the plate-flow-distribution radial variable-displacement plunger pump, the mutual unnecessary wear is avoided, the service life is prolonged, the production cost is reduced, the structure is simple and the mass production is facilitated.
Description
technical field [0001] The invention relates to a power element of a self-distributing flow servo variable control mechanism of a radial variable plunger pump valve core, in particular to a novel rotating structure of a disc flow radial variable plunger pump. Background technique [0002] At present, due to the complex structure of the foreign traditional radial piston pump, it is difficult to process, and it is difficult to popularize due to the limitation of processing conditions. Due to the limitations of its own structure, it cannot be well matched with the radial variable piston pump with disc flow distribution, resulting in easy wear and increased production costs. Contents of the invention [0003] The technical problem to be solved by the present invention is: due to the limitation of its own structure, the existing rotating structure cannot cooperate well with the disc-distributed radial variable piston pump, resulting in easy wear and increased production costs....
