Short axial spacing bearing seat for centrifugal pump

The utility model belongs to the field of centrifugal pumps, and particularly relates to a short-axial-spacing bearing seat for a centrifugal pump, which comprises a bearing seat, a bearing seat cavity is arranged in the bearing seat, a pump shaft is movably connected to the middle of the bearing seat, an oil groove is arranged at the position of the pump shaft opposite to the bearing seat cavity, a bearing is arranged on the right side of the bearing seat cavity, and the bearing seat cavity is communicated with the oil groove. The bearing sleeve is arranged on the annular side of the pump shaft, and a bearing seat oil cavity is formed in the lower portion of the interior of the bearing seat. A lubricating oil cavity does not need to be enlarged by lengthening the axial distance of the bearing seat, in the rotating process of the pump shaft, lubricating oil is driven to flow through the arranged oil groove, it can be effectively guaranteed that enough lubricating oil is stored, the temperature of the bearing
