Axial -flow pump with from cutting function

The utility model relates to an axial -flow pump with from cutting function. The utility model discloses connect a plurality of cutting pieces on the water guide cap of axial -flow pump to it arranges to use the pump shaft to divide equally as the center pin. The utility model overcomes long flexible debris easily twined the axial -flow pump blade past, and the rigidity debris of large granule then can directly clash into the axial -flow pump impeller, reduced axial -flow pump device hydraulic efficiency, increased the output of axial -flow pump motor, worsened the operating environment of axial compressor pump station, seriously will result in defects such as axial -flow pump unit oscillation generation. The utility model discloses structure science is simple, and reasonable in design adopts the cutting piece to solidify in the water guide cap, forms integratively with the axial -flow pump impeller, has realized that the cutting piece is unified with the entity of blade, and need not increases cutting device especially, and the axial -flow pump with from cutting function impeller has good water conservancy performance, nos jam nature, the life of extension axial compressor impeller of pump, the maintenance cost of reduction impeller.
