Theoretical and practical aspects of the wear of vane pumps
Part A. Adaptation of a model for predictive wear calculation
Abstract
  The aim of this investigation is the development of a mathematical tool for predicting the wear behaviour of vane pumps uscd in the standard method for indicating the wcar charactcristics of hydraulic fluids according to ASTM D 2882/DIN 51
389.
   The derivation of the corresponding mathematical algorithm is based on the description of the combined abrasive and
adhesive wear phenomena occurring on the ring and vanes of the pump by the shear energy hypothesis, in connection with
stochastic modelling of the contacting rough surfaces as two-dimensional isotropic random fields. [版权所有：http://DOC163.com]
  Starting from a comprehensive analysis of the decisive ring-vane tribo contact, which supplies essential input data for the wear calculation, the computational method is adapted to the concrete geometrical, motional and loading conditions of thetribo system vane pump and extended by inclusion of partial elastohydrodynamic lubrication in the mathematical modej.
  For comparison of the calculated wear behaviour with expenmental results, a test series on a rig described in Part B was carried out. A mineral oil-based lubricant without any additives was used to exclude the influence of additives which cannot be described in the mathematical model. A good qualitative correspondence between calculation and experiment regarding the temporal wear progress and the amount of calculated wear mass was achieved.
