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

The sealing structure of a space guide vane suspended semi submersible vertical turbine pump includes a space guide vane, pump shaft, bearing assembly, protective tube, connecting tube, mechanical seal shaft sleeve, double end mechanical seal, mechanical cover, impeller, and impeller nut. The pump shaft is positioned inside the space guide vane through the bearing assembly, and the space guide vane, protective tube, and connecting tube are connected as a whole through bolts; The machine seal shaft sleeve is placed on the pump shaft and positioned through a flat key; The dual end mechanical seal is located between the mechanical seal shaft sleeve and the space guide vane; The machine seal cover is tightly matched with the double end mechanical seal, machine seal shaft sleeve, and space guide vane, and is fixed by tightening with screws; The impeller is mounted on the pump shaft and locked by a flat key and impeller nut connection. Plays a role in protecting the pump shaft and bearing components, improving the normal performance of the pump unit and extending its service life.
