Lagerungstechnik für Turbopumpen

Bearing technology in turbopumps This contribution provides an overview of the development undergone by bearing technology in turbomolecular pumps or, in short, turbopumps. It not only describes which conventional bearing configurations are encountered today, but also explains the pros and cons of the various configurations. The path to using turbopumps with full magnetic bearings was paved with various difficulties in the early nineties. The concluding description of the current state of the art, with the focus on safety, reliability, user‐friendliness, maintenancefree design and energy efficiency, illustrates how the development of turbopumps has undergone fundamental changes.
