Oblique plunger type pure water hydraulic swash plate pump

Abstract

The invention relates to an oblique plunger type pure water hydraulic swash plate pump, which adopts a sphere flow distribution structure of a cone-shaped cylinder. A plunger and a transmission shaft form an included angle, and relative to the transmission main shaft, the plunger is arranged in a shape of cone; and centripetal force generated during operation facilitates return stroke of the plunger. The main shaft is connected with a conical cylinder via a spline, and the plunger is matched with skid shoes via a ball head. A spherical hinge and the cone-shaped cylinder are pressed by a disk spring, return stroke force during the operation of the plunger is provided and sealing of the skid shoe pair and the flow distribution pair is achieved. A flow distribution disc adopts a sphere flow distribution structure, facilitates balancing of subversion moment generated by the cone-shaped cylinder during operation, and improves the self-alignment performance of the cone-shaped cylinder and the flow distribution plate; the cone-shaped cylinder and the sphere flow distribution disc structure enable the flow distribution window pitch diameter of the flow distribution disc to be reduced, water absorption flow rate is reduced, and self-sucking performance of a pump is enhanced. The pump takes filtered fresh water or seawater as the working medium, solves the problems that the self-sucking performance of a pure water hydraulic plunger pump is poor and the return stroke is difficult, and has remarkable technical advantages.

Description

technical field [0001] The invention relates to an inclined plunger type pure water hydraulic swash plate pump, which can be used as a power element in a pure water hydraulic transmission system and belongs to the technical field of fluid transmission and control. Background technique [0002] Pure water hydraulic technology is a new technology that uses natural fresh water or sea water instead of mineral oil as the working medium of the hydraulic system. In recent years, based on the increasing emphasis on safety and sanitation, energy conservation, environmental protection and ocean development, the research on pure water hydraulic technology has become a frontier research topic in the international hydraulic industry. Compared with hydraulic transmission using other types of media, pure water hydraulic transmission has the following advantages: [0003] (1) Environmentally friendly and pollution-free. Generally, the leaked water does not need to be recycled, and will no...
