JET PUMP UNIT Russian patent published in 2022 - IPC F04F5/02 

FIELD: jet technology.

SUBSTANCE: invention relates to the field of jet technology, including jet pumps and compressors, jet control systems and jet propulsion systems for dynamic positioning. A jet pumping unit is proposed, containing sources of a working medium and a pumped medium, a jet pump equipped with a system of nozzles hydraulically connected in parallel and placed at the inlet to the working chamber with the formation of an annular channel, in which U-shaped pockets are placed with the formation of isolated each other in them. from each other inlet channels, each of which has one nozzle and which hydraulically connect the working chamber with the sources of the pumped medium through shut-off control devices, while the source of the working medium is hydraulically connected to the inlets of the nozzles, and the sources of the pumped medium are hydraulically connected to the annular channel.

EFFECT: claimed technical solution can be used in the oil and gas industries to improve the efficiency of technologies in the extraction and processing of hydrocarbons, including in the development of offshore fields.
