The Wear Features and Destruction Mechanisms of the Working Stages of a High-Speed Pump

The results of research on the modernized SKI LX bench, which provides addition to the model fluid of various kinds of abrasive particles, the nature and properties of which can correspond to real operating conditions, are presented. In developing the program and methodology of these studies, we used the after exploitation analysis of high-speed pumping units carried out at the fields of various companies in the Russian Federation. The features of wear and the mechanisms of destruction of the working stages of the 92ELNC85-2250-e2OE-10ETS high-speed pump series were investigated. On a real design of a high-speed pump the possibility to determine the wear rate of tribo-contraction elements by the method of its weight determination with a forecast for the resource and to reveal the ways of its increase in a wide range of the number of suspended abrasive particles in the model fluid, and in particular, in water is shown. The results in this work are the basis for the development of scientifically based methods for studying the wear resistance of bearing assemblies of high-speed centrifugal pumps in conditions of a wide variety of reservoir fluids and suspended particles contained in them.
