Subject of research
Creation of conditions for optimal design methods of lubrication systems using ecological greases, i.e. especially: - value determination of rheological and temperature-viscous parameters of ecological greases of viscous classes NLGI 00, 0, 1, 2 for temperature extent -20 to +40 deg. C, shear deformation velocity 0,2 to 20 and the defined state of grease plasticization -experimetnal verification of head losses in tubing at grease laminar flow by means of an experimental stand and comparison with computed values according above mentioned methodology (using Oswald, Bingham or Bulkley-Herschel rheological model) - experimental determination of local head losses in certain chosen cases, mathematical description by measn os head losses coefficients -experimental and theoretical research of pulsatio grease flow through elastic tubes on condition of medium compressibility by means of mathematical modelling - mathematical modelling of the main mechanisms of central lubrication systems for ecological
