Problems solved by technology
The shaft flow distribution and end face flow distribution methods used in traditional hydraulic hydraulic pumps are not suitable for emulsions due to large leakage, and emulsions cannot achieve a good lubricating effect due to poor lubricity. The amount of mineral oil required for the lubrication function is far from It is less than the amount of traditional mineral oil as a whole, so mineral oil is still used as the lubricating medium, which requires a hydraulic pump with a new flow distribution method
Most of the existing mineral oil hydraulic pumps have complex structures, large volume and mass, large inertia of moving parts, and are not very convenient to use

The invention belongs to the technical field of hydraulic pump devices, and particular relates to a valve type flow distribution axial convex disk ball plug emulsion pump. The valve type flow distribution axial convex disk ball plug emulsion pump comprises a transmission shaft, a convex disk, a movable cylinder, a cylinder body and a rear end cover. The cylinder body and the rear end cover form asealed pump body, and the transmission shaft drives the convex disk. The working surface of the convex disk is a uniform multi-action inner curve concave-convex surface, and the convex disk is installed in a thrust ball bearing. The convex disk is installed in the cylinder body through the thrust ball bearing, and the movable cylinder is installed in the cylinder body. According to the valve typeflow distribution axial convex disk ball plug emulsion pump, a plunger and the cylinder body no longer rotate with the transmission shaft, and the reciprocating movement of the plunger in the cylinderbody is realized by the rotation of the convex disk, so that the absorption and pressing of emulsion is realized. The plunger structure of the pump is improved, and a flow distribution shaft or a valve plate is no longer used in the flow distribution process, and the flow distribution is realized by two quick response flat valves.
Description
technical field [0001] The invention belongs to the technical field of hydraulic pump devices, in particular to a valve-type flow distribution axial convex disc ball plug emulsion pump. Background technique [0002] At present, the working medium of most hydraulic pumps is mineral oil-type hydraulic oil, but due to the characteristics of flammability, pollution and non-renewability of mineral oil-type hydraulic oil, it has seriously hindered the application of such pumps in a series of occasions such as mines. use. In order to expand the scope of use of hydraulic pumps or motors, simplify some mechanized systems and improve economic benefits, the use of water and other low-viscosity green transfer media instead of mineral oil is of great significance to efficient, safe and green mining of coal, so high-pressure and large-flow emulsions are developed. Pumps are very practical. The shaft flow distribution and end face flow distribution methods used in traditional hydraulic h...
