Abstract
This paper deals with an experimental study of the interface lubrication conditions and of the dynamic behavior for low pressure mechanical seals.
Two test cells, equiped with the same carbon rotor, have been developed. The first cell is extensively instrumented with electrical transducers and the second cell is devoted to optical methods.
Two main lubrication regimes are demonstrated :
-
— Large geometrical defects induce pure hydrodynamic regime with no wear and possible appearance of leakage.
-
— Low geometrical defects leads to a combination of contact on the low pressure border and hydrodynamic film in the rest of the interface.
Soft contact associated with appropriate thermoelastic distorsions leads to zero leakage and acceptable wear.
