Abstract

Wirowa pompa wielostopniowa z wirnikami jednostrumieniowymi charakteryzuje sie tym, ze wirnik (2) ostatniego stopnia ma wystep (4) na tylnej tarczy (3) i wraz z uszczelnieniem (5) tworzy komore odciazenia (6), która przewodem (7) jest polaczona z kadlubem ssawnym. W innym rozwiazaniu wirnik (2) ostatniego stopnia ma wystep (4) na tylnej tarczy (3) i wraz z uszczelnieniem (5) tworzy komore odciazenia(6), która jest polaczona przewodem upustowym (10) z otoczeniem.The multistage centrifugal pump with single-stream impellers is characterized by the fact that the impeller (2) of the last stage has a protrusion (4) on the rear disk (3) and together with the seal (5) forms a pressure chamber (6), which is connected to the pipe (7) suction hull. In another embodiment, the impeller (2) of the last stage has a protrusion (4) on the rear disk (3) and together with the seal (5) forms a relief chamber (6) which is connected to the bleed pipe (10) with the surroundings.
