Annotation:

Electric submersible pumps (ESP) are widely used when operating small-diameter sidetracks. When using stages with open impellers in these pumps, it becomes possible to reduce the axial dimensions and vibration loads occurring in the equipment. However, these stages have a number of problems, one of which is the relatively low discharge head and efficiency indicators. The results of numerical studies of some geometric parameters influence of open impellers (in particular, the number of impeller blades, the angle of inclination of the impeller blades, as well as changes in the axial clearances between the working elements of the stage) on the characteristics of the electric submersible pump stages are presented. The ranges of optimal geometric parameters are shown, as a result of which it is possible to achieve the highest values of discharge head and efficiency of the ESP stage with open impellers.
