Theoretical Fundamental Research Of The Double-oblique-type Axial Piston Pump

Hydraulic systems are widely used in national defense, mining, metallurgy, aerospace and other departments because of the convenient flow conditioning,fast controllable stress response,big power density, convenient power transmission and distribution,easy to achieve straight line movement and implementation of wide range of stepless speed regulation and so on. As the heart of the hydraulic system, power components are constant developing with the hydraulic and technological progress, particularly in the widely used aspects of the axial piston pump. Double-oblique-type axial piston pump is a new type of hydraulic power components that developed from the fundament of the traditional Swashplate axial piston pump. Compared with the traditional Swashplate axial piston pump, it has many significant advantages, such as large geometric flow,small size and a higher speed in the same component materials.The thesis has induced structural principle, the exercise curve equation of double-oblique-type axial piston pump; induced forces of main components and calculative equations of structure size parameters of main components under the conditions of balanved forces and torque; Analysed flow pulsation characteristics and Pulsating flow coefficient under different number of plungers of double-oblique-type axial piston pump, analysed geometry factors that influence flow pulsation characteristics; Compared the similarities and differences at sports, force and flow pulsation aspects of the double-oblique-type axial piston pump and Swashplate axial piston pump.For comparison of the double-oblique-type axial piston pump and Swashplate axial piston pump, this article mainly use the MATLAB software to simulate related paraments, including contrast of geometric displacement, flow curves, flow pulsation and other factors. Through the simulation analysis, we can clearly know advantages and disadvantages of the double-oblique-type axial piston pump,meanwhile can have a more intuitively and Comprehensive knowledge for performance of it.
