Investigation into the Causes of Pulsation of Flow of Hydraulic Pumps and Its Effects

B. J.Patil , Dr. V. B.Sondur

This research paper investigates the flow ripple of the hydraulic pumps. For the idealized case, an axial piston pump, gear pump and swash plate pumps with axial pistons are examined without leakage in to account. The number of pistons varied in case of axial piston pumps and the number of teeth on driving as well as driven gears are changed for the purpose of reducing the intensity of flow pulse. The effect of flow pulse on the pressure transition results of the pressure relief valve also investigated
