The influence of obliteration of slott ed gaps of plunger couples at the stage of design and calculation of drive systems for aggregates of electric power systems is considered. Obliteration is considered as a harmful phenomenon, on the basis of this, it is necessary to search for methods and means that contribute to the stabilization of flow. Such a problem arises whenever it is necessary to obtain small and stable over time fluid flow rates. Since obliteration is always accompanied by an increase in the forces required to move the mating parts relative to each other, for example, a plunger in a sleeve, ignoring this phenomenon can lead to underestimated costs of leakage of the working fluid. These efforts are all the more, the more active is the obliteration process. The analysis of experimental studies for various types of liquids with different gaps and pulsations of the pressure drop at the ends of the gap. The obliteration process, caused by the adsorption of liquid molecules, was approximated by an exponential function that allows you to determine the maximum possible thickness of the boundary layer of liquid formed on the channel wall.
