Abstract

The invention relates to the technical field of submerged pumps, and specifically discloses a vertical cantilever centrifugal submerged pump; including a motor, a motor bracket, a base, a bearing seat, a hollow connecting pipe, a pump body, a centrifugal impeller, an upper pump shaft and a lower pump shaft, The bearing seat is fixedly installed on the upper surface of the base, the motor bracket is fixedly installed on the upper end of the bearing seat, the motor is fixedly installed on the motor bracket, the upper and lower ends of the bearing seat are equipped with bearings, and the output shaft of the motor is connected with the upper pump shaft through a coupling. Connection, the upper pump shaft is set through the bearing seat and welded with the inner ring of the bearing, the hollow connecting pipe is connected to the lower surface of the base directly below the bearing seat, the lower end of the hollow connecting pipe is connected to the pump body, and the connection between the hollow connecting pipe and the pump body is provided with Seal assembly; the invention can effectively solve the imbalance caused by the radial thrust around the centrifugal impeller, reduce the wear between the pump shaft and the bearing caused by the imbalance state, and greatly prolong the service life of the submerged pump.

Description

technical field [0001] The invention relates to the technical field of submerged pumps, and specifically discloses a vertical cantilever centrifugal submerged pump. Background technique [0002] At present, vertical submerged pumps are widely used in mines, power plants, petrochemicals and other industries to transport liquids such as mud, paper pulp and sewage. The vertical motor of the submerged pump is fastened to the motor base with bolts, and is directly driven by the elastic coupling with the pump, the pump body, the intermediate connecting pipe, the pump frame, the liquid outlet pipe, and the pipe flange, which are connected by bolts to form an integral body. On the bottom plate, the whole of the vertical submerged pump is then installed on the container through the bottom plate. In the process of conveying the liquid, when the liquid contains large particles, it will cause abrasion, which will increase the clearance of the bearing, and at the same time, the length o...
