Through-shaft axial piston pump capable of realizing energy recovery

Abstract

The invention discloses a through-shaft axial piston pump capable of realizing energy recovery, and relates to the technical field of fluid machinery. The through-shaft axial piston pump comprises a pump body, a transmission shaft, a cylinder body, a swash plate, wherein an axial hole is formed in the cylinder body, and a piston is arranged inside the axial hole; the through-shaft axial piston pump further comprises a piston resetting device; an inner cavity of the cylinder body comprises a rodless cavity located on the side, away from the swash plate, of the right side of the piston as well as a rod cavity located on the left side of the rodless cavity and internally provided with a piston rod, wherein the rod cavity and the rodless cavity communicate with the outside of the cylinder bodythrough channels; and the pump body is further provided with a first fluid discharge channel, a first fluid indraft flow channel, a second fluid indraft channel and a second fluid discharge flow channel. According to the through-shaft axial piston pump capable of realizing energy recovery, input of external force is effectively reduced, recycling of waste energy is achieved, the structure is simple, manufacturing is convenient, lubricating effects of the piston are improved, friction is reduced, good economic benefits are brought, and adaptability is high.

Description

technical field [0001] The invention relates to the technical field of fluid machinery, in particular to a thru-shaft axial piston pump for realizing energy recovery. Background technique [0002] my country is rich in water resources, but the per capita share is relatively small. At the same time, due to the large population in our country, the demand for fresh water is very large. In my country's seawater desalination projects, a large amount of waste concentrated seawater with a certain pressure energy will be produced. If the factory fails to fully utilize the waste concentrated seawater, it will cause a waste of energy in the waste fluid. It not only increases the production cost of fresh water and reduces production efficiency, but also affects the service life and utilization rate of seawater desalination equipment. [0003] The main function of the traditional through-shaft axial plunger pump is to distribute flow through the valve plate, and the plunger moves back ...

In my country's seawater desalination projects, a large amount of waste concentrated seawater with a certain pressure energy will be produced. If the factory fails to fully utilize the waste concentrated seawater, it will cause a waste of energy in the waste fluid

It not only increases the production cost of fresh water and reduces production efficiency, but also affects the service life and utilization rate of seawater desalination equipment

[0003] The main function of the traditional thru-shaft axial plunger pump is to distribute the flow through the valve plate, and the plunger moves back and forth in the cylinder to realize the suction of low-pressure fluid and the discharge of high-pressure fluid, and it does not have the function of recovering the pressure energy of waste seawater.

Ordinary seawater desalination high-pressure pumps also do not have the function of energy recovery, and the efficiency is lower
