Problems solved by technology

[0005] 1) The speed is low, the volume is large, the power-to-mass ratio is low, and the lubricating oil chamber is in a closed state. Increasing the speed or pressure will cause severe heat generation and easy failure. In addition, the temperature rise caused by heat generation will cause oil deterioration and affect its lubrication effect
[0006] 2) The use of mineral oil for lubrication is likely to cause oil leakage and pollution, which is not conducive to environmental protection

Abstract

The invention belongs to the field of water pumps, and discloses a swash plate type water pump. The swash plate type water pump comprises a cylinder body, a left end cover, a right end cover, a spindle assembly, a swash plate, a plurality of groups of plunger compression assemblies and distributing valves, wherein a water inlet channel is formed in the cylinder body, and a drain channel is formedin the right end cover; the spindle assembly comprises a rotary spindle; the swash plate is fixedly installed on the rotary spindle in a penetrating mode; each group of the plunger compression assembly comprises a return block, a plunger assembly, a cylinder sleeve assembly and a distributing valve assembly; the distributing valve assemblies are respectively installed in positions, which correspond to cylinder sleeves, of the right end cover, liquid communication flow channels are respectively formed in positions, which correspond to the distributing valve assemblies, of the right end cover, and all of the liquid communication flow channels communicate with the drain channel in the right end cover. According to the swash plate type water pump, the rotary motion of the spindle is convertedinto a straight reciprocating motion of the plunger assemblies through a spherical hinge and the return block, and the swash plate type water pump has the advantages of simple structure and smooth motion transfer.

Description

technical field [0001] The invention belongs to the field of water pumps, and more specifically relates to a swash plate water pump. Background technique [0002] With the emergence of the energy crisis and the improvement of the world's environmental protection diet, and the natural advantages of the water medium itself such as no pollution and good safety, water hydraulic technology has the advantages of oil pressure systems in many fields (such as underwater operations, buoyancy adjustment, etc.) Comparable advantages, so water hydraulic technology has been developed rapidly. [0003] Due to the poor lubricity and strong corrosion of water, the existing all-water lubricated plunger pumps are very limited in material selection, and the working pressure range is mainly medium and high pressure, and the volumetric efficiency and service life under high pressure are difficult to guarantee. . In addition, it is sensitive to pollution and requires high filtration accuracy, so...
