Wear performance analysis and simulation of external gear pump

As a kind of hydraulic power component, the external gear pump determines the performance of the entire hydraulic system. Gear pumps are subjected to various degradation such as wear which deteriorate the performance of the gear pump. The purpose of this research is to analyze the wear degradation of external gear pump under various operating conditions like speed, pressure and radial gap between gear tooth and casing. As wear affect the performance of gear pump, optimization of operating conditions on the performance of gear pump was studied. External gear pump is modelled in Fusion 360, and ANSYS CFD analysis was used for the simulation of volumetric efficiency under various operating conditions. The pump was simulated at different operating speeds and radial wear gaps.
