Model of the Floating Bearing Bushing Movement in an External Gear Pump and the Relation to Its Parameterization

This article presents the modeling, simulation and experimental validation of movement floating bearing bushing in an external gear pump. As a starting point, complete pump parameterization was carried out through standard tests, these parameters were used first bond graph model order to simulate behavior. experimentally validated under working conditions field tests. Then, sophisticated developed from equations that define its lubrication. Finally, as result, both models merged by integrating dynamics with variation characteristic (loss coefficients). final laboratory tests assembling drilling machine drive auxiliary movements. The novelty this is conception construction simple tool for study pump, which relates macroscopic behavior black box (defined loss coefficients) internal changes unit lubrication).
