Bearing structure of space guide vane suspended semi submersible vertical turbine pump

The bearing structure of a space guide vane suspended semi submersible vertical turbine pump includes space guide vanes, pump shaft, rolling bearing components, bearing cover, secondary impeller, protective tube, connecting tube, "O" ring, and sealing components; The space guide vane is equipped with rolling bearing components; The pump shaft is positioned and fixed within the spatial guide vane through the rolling bearing assembly; There is a sealing component between the pump shaft and the space guide vane below the rolling bearing; There are bearing covers and protective tubes above the sealing components and rolling bearings; There is a sealing component between the bearing cover and the pump shaft. O-ring seals are installed between the bearing cover and the space guide vanes, as well as between the protective tube and the space guide vanes for sealing purposes. This technical method replaces the guide bearing structure of the original suspended semi submersible vertical turbine pump, optimizes the rolling bearing component structure between the existing space guide vanes, protective tubes, and connecting tubes, reduces manufacturing costs, saves materials, simplifies the pump assembly structure, and is more convenient to operate.
