- Abstract
- This paper shows the experimental results obtained using a nano-coating (developed by ISTECC.
N.R.), applied to the slippers of an axial piston pump, to reduce the friction losses in order to
improve the pump overall efficiency map. Is well known, that the mechanical power losses in a
hydraulic pump come from the friction between parts in relative motion. The need to provide,
especially at low rotational speed, hydrodynamic lift, causes power losses, in terms of volumetric
and mechanical efficiency, due to the contrasting need to increase leakage to provide lubrication
and to keep a minimum clearance in meatus to limit the volumetric losses. The application of
special surface treatments have been exploited in pioneering works in the past, trying different
surface finishing or adding ceramic or heterogeneous metallic layers, but the potential of
structured coatings at nanoscale, with superhydrophobic and oleophobic characteristics, has never
been exploited. Using a dedicated test rig developed at IMAMOTER-C.N.R., able to ensure
hydrostatic working condition during the mutual rotation between the slippers and the swash plate,
the functional performance of the nano-coated slippers surface have been studied. In the first part
of the paper the functionalization method is presented; in the second part a comparison between the
experimental performances of coated and uncoated surfaces is showed. (literal)
