Problems solved by technology
[0004] Most of the existing plunger-type emulsion pumps are horizontal pumps, which not only occupy a large area and are complicated to install, but also have a large friction force between the plunger and the plunger pump during work, which reduces the work efficiency; in addition, it is necessary to install a series of Sealing device to avoid mutual leakage of emulsion and lubricating oil, the structure is more complicated

The invention relates to a device in the technical field of plunger type hydraulic pumps or motors, in particular to a high-water base plunger type hydraulic pump or motor axial stretchable cylinder assembly. The axial stretchable cylinder assembly comprises a pump cylinder block, a liquid inlet valve, a plunger cavity end cover, an axial stretchable cylinder, a liquid outlet valve, a cylinder sleeve and a plunger; the cylinder sleeve is sleeved with the pump cylinder block, the axial stretchable cylinder is installed at the upper portion of the cylinder sleeve, the bottom of the cylinder sleeve and the plunger are welded, an axial stretchable cylinder liquid inlet and outlet opening e is formed in the middle portion of the axial stretchable cylinder, one end of the axial stretchable cylinder liquid inlet and outlet opening e communicates with the interior of the cylinder sleeve, the other end of the axial stretchable cylinder liquid inlet and outlet opening e communicates with a plunger cavity end cover interior runner d arranged on the plunger cavity end cover, and the two ends of the plunger cavity end cover interior runner d are provided with the liquid inlet valve and the liquid outlet valve. According to the high-water base plunger type hydraulic pump or motor axial stretchable cylinder assembly, a lubrication system can be separated from a power system, consumption of traditional non-renewable energy resources such as lubricating oil is reduced, water lubrication replaces oil lubrication, and the lubrication and friction performance of the plunger type hydraulic pumps or motors are greatly improved.
Description
technical field [0001] The invention relates to a device in the technical field of a plunger hydraulic pump or a motor, in particular to an axially retractable cylinder assembly of a high water-based plunger hydraulic pump or a motor. Background technique [0002] At present, the working medium of most hydraulic pumps or motors 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 use of such pumps or motors in mines, etc. use in a range of situations. In order to expand the application range 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 coal mining. [0003] Today's water hydraulic plunger pumps or plunger motors use water as the transmission and lubrication medium....
