Analysis of Gear Pump Designed for Manufacturing Processes

Abstract:

The model for the analysis of the gear pump work designed for the hydraulic systems was made for the 3D non-stationary two-phase flow using CFD software. In this paper, we made the simulation calculation of the pressure surge when opened between gear space in the discharge tube while the liquid is pumped. At the same time, we detected the pressure, velocity fields and the volume fraction of the steam in the gear pump space. The paper presents the resultant of the forces and the moments acting on the gears and possible sites of cavitation in the area of the gear pump and on its bearings. All the obtained results have been examined in the practical manufacturing processes.
