Multi-action inner-curve radial piston type fluid pump

Abstract

The invention discloses a multi-action inner-curve radial piston type fluid pump capable of utilizing energy in a waste fluid. The multi-action inner-curve radial piston type fluid pump comprises a pump body, a cylinder body, a transmission shaft set, piston sets, a flow distribution plate and the like. According to the multi-action inner-curve radial piston type fluid pump, rod cavities of the piston sets communicate with a waste fluid suction channel and a waste fluid discharging channel correspondingly, rodless cavities communicate with a useful fluid suction channel and a useful fluid discharging channel correspondingly, the rod cavities communicate with waste fluid with certain energy, the rodless cavities communicate with useful fluid, when pistons and piston rods are retracted inwards, the rod cavities suck the waste fluid with the certain energy, the useful fluid is discharged from the rodless cavities, when the pistons and the piston rods extend outwards, the rodless cavitiesare used for discharging the waste fluid which is subjected to energy recovery, and the rodless cavities are used for sucking the low-pressure useful fluid. When the useful fluid in the rodless cavities needs to be pressurized, the pressure energy in the waste fluid in the rod cavities and the external force are utilized to work together so that the input of external force can be reduced, the pressurization of the useful fluid is realized, meanwhile, the energy recovery is realized, and the cost is saved.

Description

technical field [0001] The invention belongs to the field of fluid transmission and control, in particular to a multi-action internal curve radial piston fluid pump. Background technique [0002] Energy is the cornerstone and foundation of social production and development, and its consumption rate is an important indicator to measure economic benefits. With the rapid development of society, the consumption and demand for energy are increasing day by day. Solving the energy crisis has become a top priority, and there are two main solutions: one is to develop new energy to replace traditional energy; the other is to save energy and enhance the utilization rate of energy. [0003] my country is rich in water resources, but the per capita is relatively small. Due to the large population, 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...

Problems solved by technology

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 manufacturing cost of fresh water and reduces production efficiency, but also affects the service life and utilization rate of seawater desalination equipment
