Research on a new type of water hydraulic vane pump

Under consideration of the physical and chemical properties of water and water hydraulic transmission characteristics, the principle and structure of a new type of water hydraulic vane pump is provided in this paper. This pump has changed the vane´s radial motion into the axial motion so that the size of the pump is reduced and has a feature of smooth displacement and low noise. Because it reduces material requirements for stiffness of the main pump components, resulting in this machine has a possibility to manufacture components from polymers and engineering-plastics. The virtual prototype has been designed to undertake further industry applied research.
