Study on the Influence of Flow Distribution Structure of Piston Pump on the Output of Pulsation Pump

According to the working principle of A10VNO swashplate axial piston pump, output flow model an pump in ideal state and theoretical considering leakage distribution process are established. The pulsations odd even pumps simulated analyzed by Matlab, influence a closed dead angle mismatch port plate on pulsation is obtained. Based model, AMESim used establish overall leakage, oil compressibility under constant conditions. By setting six different boundary conditions corresponding research, structure studied. A test-bed was built verified experiments. results show that when valve 3–5° 6–10°, difference between very small, so hydraulic motor system, as condition power recovery, number or adjacent motors appropriate.
