Development and Research of Multi-Phase Reversible Pump

摘要

The purpose of this research is the forming of novel scientific principles for the transfer of multiphase media by using reversible pumps in the development of oil and gas fields. One of the tasks is associated with the transfer of a multi-phase medium during a high concentration ofthe solid phase in the flow. This article demonstrates the prospects of using reversible pumps for pumping multiphase media. New design methods have been tested using additive technologies when conducting scientific research. The research results expanded the technological capabilities forthe creation of new labyrinth pumps. It is shown that the auger in the labyrinth pump can be replaced with a set of paddle wheels. The impeller itself, as part of the labyrinth pump’s rotor, can perform as a centrifugal or axial wheel. This area of hydraulic machinery is yet unexplored.Therefore, it is advisable to continue and expand the research work in this field, considering the variety of options for rotor design. The labyrinth pump has the properties of a multistage pump, with a series connection of pumping stages. The authors considered working conditions for a labyrinthpump, under which the most uniform load distribution between the pumping stages could be ensured. The pressure distribution over the pumping stages was considered when pumping a liquid-gas mixture for different values of the rotor speed.Separate research results can be used to create a newpumping compressor and turbine technology for various industries, including transportation and robotics.
