FIELD: electric centrifugal pump units.
SUBSTANCE: self-cleaning filter for protection of an electric centrifugal pump unit (ECPU) refers to the mining industry and is designed to protect deep oil pumps from mechanical impurities contained in the reservoir fluid. The self-cleaning filter contains a frame, a shaft 8, on which the fine 6 and coarse 7 filter elements are mounted for rotation, additionally contains an external 2 and an internal 10 needle bearing and an inversion clutch 9 equipped with rollers. The frame is made of alloy steel and consists of elongated rods 5 of triangular shape and a flange-housing 1 connecting them. engagement with the coarse filter element 7, on which the fine filter element 6 is radially fixed.
EFFECT: increasing the service life of the pump by using the possibility of switching the ECPU to reverse rotation.
