Definitions

  • the invention relates to an impeller to be used inside submersible pumps for transporting fluids between two predetermined locations by transferring mechanical energy to working fluid in order to increase total head, using at least one drive unit.
  • WO2021260974 known in the literature relates to a submersible pump for minimizing the formation of blockages.
  • a non-blocking pump is provided with a pump body, an impeller comprising a main plate part, a blade part, and a central protruding part.
  • the pump structures in the current art are examined, it is seen that they encounter some problems during the transportation of the fluid.
  • One of these problems is the obstructions experienced during the transportation of the fluid.
  • pumps transportation capacity may decrease when fibrous materials are present in the working fluid. Depending on their length these fibrous structures may possibly wrap around the hub or the leading edge of the impeller, which causes some issues.
  • FIG. 2 illustrates a representative perspective view of the impeller (20) of the invention. Accordingly, the inventive impeller (20) prevents the pump (10) from being clogged by chopping the solid and fibrous materials in the transported fluid as well as transferring mechanical energy to the fluid.
  • Figure 4 illustrates a representative perspective view of at least one impeller cover (40) shaped using the same meridional section at the outer streamline of the impeller (20) of the invention. Accordingly, the said impeller cover (40) is positioned in the volute (12) adjacent to the impeller (20).
  • the impeller cover (40) is provided with at least one suction eye (41).
  • the said suction eye (41 ) allows the fluid to be taken into the impeller (12).
  • the fluid entering from the suction eye (41) is energized by the impeller (20) and transferred to the volute (12) and connected to the line to be used with the discharge opening (13).
  • the impeller cover (40) is provided with at least one shaped part (42).
