Abstract

The invention discloses an ultra-high-pressure axial plunger pump, which belongs to the field of ultra-high-pressure technologies. According to the ultra-high-pressure axial plunger pump disclosed by the invention, a plurality of strip-shaped slide holes are uniformly distributed in the circumferential wall of a pump body, wherein a slide block capable of relatively sliding is arranged in each of the slide holes, small plunger pumps are connected to the both ends of the slide block respectively, the small plunger pumps are arranged in walls at the both ends of each of the slide holes in the pump body, and an oil inlet and an oil outlet corresponding to the each of the slide holes are formed in the both ends of the pump body; a spinning drive mechanism driven by a motor is arranged in the pump body or outside the pump body, the spinning drive mechanism is cooperated with the slide blocks in the pump body or outside the pump body, thus the slide blocks can be driven by the rotation of the spinning drive mechanism to axially slide in the slide holes, and drive plungers in the small plunger pumps to move back and forth. The ultra-high-pressure axial plunger pump disclosed by the invention is capable of realizing a variable pressure and a variable flow; moreover, a plurality of pumps can be connected in parallel, thus meeting oil supply for a large hydraulic station; an ultra-high-pressure working pressure of more than 120 MPa can be generated.

Description

technical field [0001] The invention relates to the field of ultra-high pressure technology, in particular to an ultra-high pressure axial piston pump. Background technique [0002] As the market heats up, plunger pump manufacturers continue to emerge, and there are more and more plunger pump products from different manufacturers and models. The plunger pumps commonly used at home and abroad are all pumps that reciprocate in the pump cylinder through a single plunger, so that the volume between the plunger and the pump wall changes, and the pump repeatedly sucks and discharges liquid and increases its pressure. It is very difficult for ordinary plunger pumps to achieve ultra-high pressures above 100Mpa, and it is even more difficult to achieve ultra-high pressures above 120Mpa. Contents of the invention [0003] The purpose of the present invention is to provide an ultra-high pressure axial piston pump for the above problems, which can realize variable pressure and variab...
