Development of a Start-up Model of a Submersible Electric Motor When the Electric Centrifugal Pump is Installed and Set to Operating Mode

2019 1st International Conference on Control Systems, Mathematical Modelling, Automation and Energy Efficiency (SUMMA), 2019
In this paper, we studied the control process of a submersible electric motor when the electric centrifugal pump installation was brought to the operating mode. This topic is relevant because after underground repair, the conclusion to the operating mode has many features and difficulties. For example, salt deposits on pumping and electrical equipment,

Methodological principles of bench testing the gas separators of the submersible electric centrifugal pump installations in oil production

Proceedings of Higher Educational Institutions. Маchine Building, 2023
Increase in efficiency of the centrifugal pumps used in the oil producing wells with high content of the free gas is achieved by equipping them with the gas separators, where most of the free gas is sorted out from the pumped medium and discharged into the well annular space before entering the pump inlet.
