Water pump impeller

The utility model discloses a water pump impeller, which relates to the related field of water pump impellers and comprises an upper end cover, a lower end cover is arranged below the upper end cover, blades are arranged above the lower end cover, a flow increasing device is arranged above the lower end cover, and suction and discharge of water flow are accelerated through rotation of the curved blades and a stirring rod. In this way, the suction amount and the discharge amount of the water flow by the water pump impeller can be increased, the overall flow is increased, meanwhile, the flowability of the water flow can be improved, and therefore the water pump impeller is endowed with better and stronger water pumping performance; the auxiliary device is arranged below the upper end cover, and impact force is protected and absorbed through the outer layer ring and the rubber ring, so that the impact force generated in the operation of the water pump impeller is protected and absorbed, the impact of torrent on
