Problems solved by technology

At present, the transmission mode adopted by the radial plunger hydraulic pump has the defect of large lateral force, large friction between the plunger and the cylinder hole, serious wear between the plunger and the cylinder hole, and the The overturning moment will be generated on the pump, which will have an adverse effect on the mechanical performance of the pump; secondly, for the radial piston type, it is difficult to adjust the flow rate, so we propose a radial variable piston pump

Abstract

The invention relates to the field of plunger pumps, in particular to a radial variable plunger pump, which comprises a shell seat, a putting-in opening arranged on the upper end face of the shell seat in a penetrating mode and a pump mechanism arranged on the inner side of the putting-in opening in a sliding mode in the linear direction, wherein the pump mechanism comprises a pump stator, a rotor which is arranged on the inner side of the pump stator and moves along a circular track, and a plunger part which is movably connected between the edge of the rotor and the inner wall of the pump stator, and a transmission shaft part for driving the rotor penetrates through the upper end face of the pump stator and then is connected with external power equipment; and the pump mechanism slides on the inner side of the putting-in opening in the linear direction, so that the eccentric distance between the inner wall of the stator and the rotor is changed, the pulling or pushing distance of the plunger part is changed at the same time, the service life of the plunger pump is prolonged, and flow adjustment is more convenient.

Description

technical field [0001] The invention relates to the field of plunger pumps, in particular to a radially variable plunger pump. Background technique [0002] Piston pumps are widely used in high-pressure hydraulic systems, which have the advantages of high rated pressure, high efficiency, long life, and light weight per unit power. According to the different arrangements of the plunger in the cylinder, the plunger pump is divided into a radial plunger pump and an axial plunger pump. At present, the transmission mode adopted by the radial plunger hydraulic pump has the defect of large lateral force, large friction between the plunger and the cylinder hole, serious wear between the plunger and the cylinder hole, and the The overturning moment is generated on the pump, which has an adverse effect on the mechanical performance of the pump; secondly, for the radial piston type, it is difficult to adjust the flow rate, so we propose a radial variable piston pump.
