  • Lubricating greases
  • Lubricating greases enclose oil in porous structures of aggregated thickener particles. Their tendency to separate oil under static conditions is evaluated according to DIN 51817 or DIN ISO 22285 in tests of up to 168 h with the mass fraction of separated oil as result. With an analytical photo-centrifuge
  • separated oil mass fractions can be tracked in real time in the instrument operating temperature range from 4–60 °C. Due to the higher mechanical load compared to standard tests
  • the grease samples separate more and faster oil
  • significantly speeding up the analysis process.Analytical Photo-Centrifuge Oil Separation
  • The oil release capacity of lubricating greases under static conditions is usually evaluated according to DIN 51817 [7] in the temperature range 40 °C–120 °C. The standard method provides values for the mass fraction of oil separated after 18 h (short-term test) or after 168 h (long-term test). Analytical photo-centrifuges significantly shorten oil separation measurements in the instrument operating temperature range of 4 °C–60 °C. Using a high rotor speed of 4000 rpm
  • the relative centrifugal acceleration (RCA) is 1878 times the acceleration due to gravity at the cuvette position of 105 mm and 2325 times the acceleration due to gravity at the bottom of the cuvette (position 130 mm). The resulting pressures of 1878 bar and 2325 bar respectively lead to at least 10 times faster tests for 10 mm cuvettes in order to obtain identical mass fractions of separated oil. Although it is not yet possible to convert the oil separation values obtained with the analytical centrifuge into values according to DIN 51817 [7]
  • the order of the greases tested in terms of oil separation is identical for both test methods. An advantage of measurements using an analytical centrifuge does not only provide the significantly shorter test times
  • but also enables continuous recording of the separating oil fractions with a high number of recorded data. This makes it possible to analyse the separation properties of greases for the test conditions used.Measurements with an analytical photo-centrifuge allow detailed investigations of oil separation extent and rate of lubricating greases under static conditions as a function of temperature (4 °C … 60 °C)
  • load (200 … 4000 rpm)
  • oil viscosity and thickener type and thickener concentration
  • respectively. Measurements on model greases with known formulations could thus provide a solid basis for future discussions on cause–effect relationships for oil separation of greases as a function of their formulation.
