Abstract

The invention relates to a detachable plunger piston shoe assembly of a swash plate hydraulic pump. According to the detachable plunger piston shoe assembly of the swash plate hydraulic pump, the structural form that a plunger is separated from a piston shoe is adopted, the piston shoe comprises an upper component and a lower component, a sealing check ring is installed on the lower component, during work, the pressing force of a return-stroke plate of the swash plate hydraulic pump enables the upper component of the piston shoe, the lower component of the piston shoe, and the sealing check ring to be closely attached to the plunger, and fluid leakage of a plunger ball head, an inner ball socket of the piston shoe and the end face of the piston shoe is avoided. The plunger piston shoe assembly can be applied to a pure-water swash plate hydraulic pump or a traditional swash plate oil-pressure pump and overcome the defect that an existing plunger piston shoe assembly of the swash plate hydraulic pump is difficult to machine, short in service life, poor in maintainability and the like. The detachable plunger piston shoe assembly of the swash plate hydraulic pump has the advantages of being easy and convenient to machine and manufacture, high in rate of finished products, easy to maintain, and the like.

Description

technical field [0001] The invention relates to a plunger slide shoe assembly for a hydraulic swash plate pump, which belongs to the technical field of fluid transmission and control, and in particular to a detachable plunger slide shoe assembly for a hydraulic swash plate pump. Background technique [0002] 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 marine development, the research on 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 non-polluting; generally leaked water does not need to be recycled and will not pollute the ...
