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.
