The main principles of hydroabrasive wear of parts of the pumping stages of well’s electric submersible pumps are considered in this article. The concentration, grain-size distribution and shape of solid particles have the greatest impact on the abrasion ability of particles of mechanical impurities interacting with the parts of pumping equipment. The implementation of filters is the most effective and affordable way to protect borehole electric submersible pumps from hydroabrasive wear. Filters reduce the concentration and decrease the average grain-size of mechanical impurities going through the pumping stages. The authors propose variants of constructive and schematic solutions of self-cleaning slot filters, providing an increase in the operating time of electric centrifugal pump units during production of well fluid with a high content of mechanical impurities. The operating principle of the proposed filters is described. The results of calculations of deformation of tubing string during the increase in pressure at the oil wellhead are presented, confirming the possibility of restoring the permeability of spring filter elements without lifting the pump unit to the surface.

Impellers are referred to as a core component of turbomachinery. The use of impellers in various applications is considered an integral part of the industry. So, increased performance and the optimization of impellers have been the center of attention of a lot of studies. In this regard, studies have been focused on the improvement of the efficiency of rotary machines through aerodynamic optimization, using high-performance materials and suitable manufacturing processes. As such, the use of polymers and polymer composites due to their lower weight when compared to metals has been the focus of studies. On the other hand, methods of the manufacturing process for polymer and polymer composite impellers such as conventional impeller manufacturing, injection molding and additive manufacturing can offer higher economic efficiency than similar metal parts. In this study, polymeric and polymer composites impellers are discussed and conclusions are drawn according to the manufacturing methods. Studies have shown promising results for the replacement of polymers and polymer composites instead of metals with respect to a suitable temperature range. In general, polymers showed a good ability to fabricate the impellers, however in more difficult working conditions considering the need for a substance with higher physical and mechanical properties necessitates the use of composite polymers. However, in some applications, the use of these materials needs further research and development.

“…and a finishing stage (milling, drilling, grinding, turning, cutting, etc.). To ensure that these processes are carried out, support systems such as water, electricity, compressed air must also be provided [13]. Traditional impeller manufacturing technology is uneconomical and needs to be adapted to a sustainable development strategy.…”

The time-consuming technological process of manufacturing impellers and the high production costs are the reason for the search for alternative materials and manufacturing methods. In this paper, based on a literature analysis, the performance of a pump with an impeller that was manufactured by an incremental method from polyethylene terephthalate with an admixture of glycol and carbon fibre (PETG CF) was selected and studied. Operation tests were conducted on the ship’s rotodynamic pump test bench. The composite impeller pump was shown to have an efficiency at the selected printing parameters of 26,23%, comparable to a tin bronze impeller, which has an efficiency of 27,7%. The maximum pump useful power with the impellers tested was 337 W at a flow rate of 4.42 m3 /h. The results confirm that, with a filament layer height of 0.12 mm and 100% fill in the four print contours, the pump characteristics obtained are consistent with those of the reference impeller. This fact ensures continuous operation of the ship’s pump for 48 hours which makes the chosen manufacturing method a reliable emergency method of impeller repair in offshore operations.
