Embodiment 1

[0037] like Figure 1-Figure 3Shown: This embodiment provides a high-pressure water pump 100 lubricated by water or aqueous solution, including a drive mechanism 4 , a housing 2 , a rebound structure 9 , a liquid cylinder 1 , at least one plunger 43 and a plunger cavity 12 . The liquid cylinder block 1 is also called the pump head. It has the same function as the liquid cylinder block of the existing reciprocating pump, and is one of the main hydraulic parts in the pump. The liquid cylinder block 1 has high and low pressure fluid passages and one-way valves 37. The plunger 43 corresponds to a suction valve and a discharge valve to realize the distribution of fluid, and realize the inflow of low-pressure water and the output of high-pressure water; the plunger cavity 12 can be arranged on the liquid cylinder block 1 or the shell 2, and the liquid cylinder block 1 can be integrally processed It can also be formed by combining multiple parts; the shell 2 is fixedly connected to t...

Embodiment 2

[0050] like Figure 4-Figure 5 Shown: the difference between this embodiment and the first embodiment is: in this embodiment, the eccentric structure 32 is a crankshaft, the connecting rod journal 35 is connected to the main shaft 5 through the crank 36, and the thrust structure 7 is sleeved on the connecting rod journal 35. On the outer circumference, the first anti-friction layer 8 is provided on the outer surface of the connecting rod journal 35 and / or the inner surface of the thrust structure 7 .

Embodiment 3

[0052] like Image 6 As shown, the difference between this embodiment and the first embodiment is that: in this embodiment, the eccentric structure 32 includes a main body 33 and a socket structure 34, the socket structure 34 is sleeved on the main body 33, and the socket structure 34 and the main body 33 are connected There is a gap between. The thrust structure 7 is sleeved on the outside of the sleeve structure 34 , and the first antifriction layer 8 is disposed on the outer surface of the sleeve structure 34 and / or the inner surface of the thrust structure 7 .

Abstract

The invention discloses a high-pressure water pump based on water or aqueous solution lubrication, and relates to the technical field of high-pressure water pumps, the high-pressure water pump comprises a driving mechanism, a shell, a rebound structure, at least one plunger and a plunger cavity; the driving mechanism comprises a main shaft and at least one eccentric structure arranged on the main shaft, the outer side of each eccentric structure is sleeved with a thrust structure, the thrust structures and the eccentric structures can rotate relatively, and the thrust structures and the eccentric structures form a first sliding friction pair; the eccentric structure and the thrust structure are both located in the shell, the space, where the eccentric structure and the thrust structure are located, in the shell is simultaneously used for being filled with water or an aqueous solution, and the water or the aqueous solution can enter the first sliding friction pair in the shell; when the eccentric structure rotates, the thrust structure can push the plunger to move in the plunger cavity so as to pressurize water or an aqueous solution; and the plunger moves in the plunger cavity under the action of the resilience force of the resilience structure so as to suck water or an aqueous solution. The pump is high in output pressure and good in anti-pollution capacity.

Description

technical field [0001] The invention relates to the technical field of high-pressure water pumps, in particular to a high-pressure water pump based on water or aqueous solution lubrication. Background technique [0002] High-pressure water pump is used to produce high-pressure water. As the core component, it is widely used in high-pressure cleaning, high-pressure fogging, fine mist fire extinguishing, seawater desalination, high-pressure deburring and other fields. [0003] At present, the widely used high-pressure water pumps include reciprocating pumps and water-lubricated axial piston pumps. [0004] The reciprocating pump has a long history and is widely used in the production of high-pressure water. It is mainly composed of crankshaft, connecting rod, crosshead, plunger and other components. Lubricating oil is used to lubricate the power end, and a sealing ring is required to seal the pressurized water. , while isolating water and lubricating oil. The main problems o...
