Self-circulation pressurizing bearing for submerged pump

The utility model relates to a self-circulation pressurizing bearing for a submerged pump. Characterized in that it is characterized in that it comprises, a shunting annular groove is formed in the middle (axial) position of an inner hole, matched with the rotating shaft, of the bearing, a plurality of radial flow guide holes communicated with the outer circle of the bearing are evenly distributedin the shunting annular groove along the circumference, a plurality of upper pressurizing spiral flow guide grooves and lower pressurizing spiral flow guide grooves are formed in the upper portion and the lower portion of the inner hole of the bearing respectively, and the rotating directions of the upper and lower flow guide grooves are opposite. The diversion annular grooves are communicated with the diversion holes, the upper and lower pressurization spiral diversion grooves are communicated with the diversion annular grooves respectively, the upper and lower pressurization spiral diversion grooves are opened in t
