Physics-Constraint Variational Neural Network for Wear State Assessment of External Gear Pump
IEEE Transactions on Neural Networks and Learning Systems, 2022Most current data-driven prognosis approaches suffer from their uncontrollable and unexplainable properties. To address this issue, this article proposes a physics-constraint variational neural network (PCVNN) for wear state assessment of the external ...

Modeling Run in Process in External Gear Pumps
Volume 3: Dynamic Systems and Controls, Symposium on Design and Analysis of Advanced Structures, and Tribology, 2006In this work, the authors have developed a mathematical model that simulates the run in of external gear pumps, as an useful tool in the optimization of this time-consuming process. The model calculates the wear profile of the case by enveloping the tip circle of the gears concerning all the run in steps.

A Robust Design Optimization Methodology for External Gear Pumps
ASME 2010 10th Biennial Conference on Engineering Systems Design and Analysis, Volume 4, 2010This work addresses the topic of external gear pumps for automotive applications, which operate at high speed and low pressure. In previous works of the authors, a hybrid lumped-parameter/finite-element model has been developed, in order to foresee the pump dynamic behaviour in terms of gear and casing acceleration.

CFD Model of an External Gear Pump
2017The paper presents a CFD model of an external gear pump. To investigate the fluid flow phenomena that occur in external gear pumps, one of the commercial CFD software packages was selected. The immersed solid method was used to simulate the flows induced by the rotation of gears.

The Theoretical Flow Ripple of an External Gear Pump
Journal of Dynamic Systems, Measurement, and Control, 2003In this paper, the theoretical flow ripple of an external gear pump is studied for pumps of similar size using different numbers of teeth on the driving and driven gears. In this work, the flow ripple equation is derived based upon the flow of incompressible fluid across the changing boundaries of a control volume.

Wear in external gear pumps: A simplified model
Wear, 1994Abstract Wear in external gear pumps, as used in hydraulic systems, is not uniformly distributed over the sliding surfaces. It is confirmed that wear occurs at regions of close clearance. Flow between these surfaces is complex, and existing fundamental wear models are not satisfactory.
