How Environmentally Friendly Tribological Systems Influence the Efficiency of Axial Piston Machines

Examinations have been carried out to determine suitable coatings and fluids for hydraulic displacement units. Based on investigations of the tribological system piston / bushing of an axial piston pump unit tests have been carried out with geometrically optimised components with PVD-coated surfaces...

Description
Summary:Examinations have been carried out to determine suitable coatings and fluids for hydraulic displacement units. Based on investigations of the tribological system piston / bushing of an axial piston pump unit tests have been carried out with geometrically optimised components with PVD-coated surfaces while using environmentally friendly fluids. The aim of these unit tests was the determination of efficiency, performance of the tested oil as well as its ecological properties depending on time.
