Title: Innovations by Peter Frehland in Centrifuge Technology
Introduction
Peter Frehland is a notable inventor based in Ditzingen, Germany. He has made significant contributions to the field of centrifuge technology, particularly in the cleaning of lubricant oils. With a total of five patents to his name, Frehland's work reflects a commitment to enhancing efficiency and reducing operational issues in centrifuge systems.
Latest Patents
Frehland's latest patents include a free-jet centrifuge designed for cleaning lubricant oil with reduced run-on times. This innovative centrifuge differs from traditional models by incorporating a braking device for the rotor that activates when oil pressure falls below a predetermined value. The rotor is mounted in a slide bearing that also serves as the oil inlet, complemented by a roller bearing that minimizes friction and allows for higher rotational speeds. Additionally, the design features friction partners that engage when oil pressure drops, effectively stopping the rotor to reduce noise and wear associated with run-on.
Another significant patent is the free jet centrifuge rotor, which is specifically designed for cleaning lubricating oil in internal combustion engines. This rotor includes an inlet, multiple drive nozzle outlets, and a sediment deposition surface. It is rotatably mounted in a surrounding housing with a friction bearing that also forms the rotor inlet, ensuring a sealed environment that enhances operational efficiency.
