Abstract
A sewage pump is to mount a blade set coaxially mounted between a water paddle disk and a first wheel blade within the blade chamber, wherein the blade set comprises a stationary annular blade base and a movable second wheel blade. The second wheel blade is within the annular blade base fixed to an inner wall of the blade chamber. Particularly, the stationary blade base and the second wheel blade respectively have blade sheets facing toward each other. When the sewage pump is driven by its motor, the water paddle disk, the first and second wheel blades are rotated to cause a suction force to drive precipitation flow into the blade chamber via the precipitation inlet. The first wheel blade cooperates with a gear ring to perform a first smashing stage and then the blade set performs a second smashing stage to improve the smashing efficiency of the sewage pump.
