CONTINUOUS ACTION VORTEX PUMP Russian patent published in 2018 - IPC F04D5/00 F04D13/10 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to the continuous operation vortex pumps and can be used in oil wells injection systems. Pump 20 includes inlet port 21 contacting the pumped fluid F, and outlet port 22 contacting the pump branch pipe 30. Pump 20 is driven by a shaft 40 associated with the motor assembly 50, and also has pump housing 23, inside which there are plurality of pumping stages 24. Each pumping stage 24 consists of attached to the pump housing 23 stator 240, attached to the stator 240 front part diffuser 250, attached to the stator 240 rear part diffuser 250 and connected to the shaft 40 inside the stator 240 rotor 260. Each pumping stage 24 comprises at least two inlet sections E, each of which is contacting with corresponding annular channel C. Each annular channel C is contacting with corresponding outlet section S. Inlet sections E and the outlet sections S, respectively, evenly distributed along the stator 240 inner perimeter. Pumping stages 24 are arranged so, that each outlet section S of the previous pumping stage 24 is connected to the corresponding inlet section E of the subsequent pumping stage 24.

EFFECT: proposed is a continuous action vortex pump.
