Embodiment Construction

[0010] Depend on figure 1 and figure 2 It can be seen that the solution adopted by the present invention to solve the technical problems is to provide a new type of pump cover for the radially variable plunger pump with disc flow distribution. , the transmission shaft 4 is fixed in the pump cover body 1 through the shaft seal 3 and the transmission bearing 2 .

[0011] When in use, it is assembled with the pump body, flow distribution plate, stator, rotor, plunger assembly, control valve seat, etc. to form a plate distribution radial piston pump with a valve core self-distribution servo structure. The hydraulic oil enters the pump body from the inlet and is sealed by the pump cover. The rotor is rotated through the transmission shaft, and the plunger is driven to squeeze the hydraulic oil to form high-pressure oil. The high-pressure oil is formed in the cavity of the pump body and sent to the pump body to complete the conversion from low-pressure oil to High pressure oil pr...

Abstract

The invention relates to a novel pump cover of a radially variable plunger pump with disk flow distribution. Aiming at the problem that the existing plunger pump pump cover has complex structure, difficult processing and irreparable, which makes the product appear to be expensive in general use, the present invention provides a new type of pump cover for the radial variable plunger pump with disc flow distribution, the shape of which is The pump cover body (1) with a disc-shaped structure is designed with an internal drain hole (5), and the transmission shaft (4) is fixed on the pump cover body (1) through the shaft seal (3) and the transmission bearing (2). )Inside. The new pump cover of the disc flow distribution radial variable plunger pump of the present invention, because of its shape and structural characteristics, and it can be made of gray cast iron, has strong wear resistance, simple structure, high pressure resistance, and impermeability. Leakage and runner processing are basically conventional machine tool processing, which overcomes the shortcomings of inaccurate casting runners and is convenient for mass production.

Description

technical field [0001] The invention relates to a power element of a self-distribution servo variable control mechanism of a valve core of a radial variable plunger pump, in particular to a new type of pump cover of a radial variable plunger pump with a disk distribution flow. Background technique [0002] At present, the traditional radial piston pump cover at home and abroad is difficult to popularize because of its complex structure and processing conditions. And due to the need of hydraulic control, the manufacturing method of the control flow channel on the valve cover is generally casting flow channel, which has unstable processability and low manufacturing precision, so it is difficult to popularize and the manufacturing cost is also high. Contents of the invention [0003] The technical problem to be solved by the present invention is: to overcome the defects of complex structure, difficult processing and irreparable defects of the existing plunger pump pump cover,...
