PUB - Numerical Study on Novel Hydraulic Pump ConceptCopyright: ifas
In the context of the GfT 2019 in Göttingen a publication on "Numerical investigation of the novel hydraulic pump concept" has been published.
This paper discusses a basic research on a novel hydraulic pump concept. Two pump concepts are introduced, which are basically similar to a conventional journal bearing. Differences from journal bearings are that the eccentricity is fixed for pressure build-up and there is an outlet hole in the high pressure area, through which the fluid can be delivered. As a basic study, the pressure distribution and the output flow rate of the pump are numerically analyzed using 2D Reynolds equation. The output flow rate is calculated in different operating conditions. The influence of the outlet port position and size on the output flow rate is also examined. From these results, the functionality of the concept is confirmed.
