Abstract
The invention discloses a water pump impeller. The water pump impeller comprises a shaft sleeve which is positioned on the center for sleeving a rotary shaft and a plurality of blades which are uniformly distributed at the periphery of the shaft sleeve, wherein each blade is composed of an upper blade section and a lower blade section; the bottom of each upper blade section and the top of each lower blade section are separated from each other, and a gap for allowing a liquid to flow through is formed between the bottom of each upper blade section and the top of each lower blade section. According to the water pump impeller, turbulent flow is increased by disconnecting the upper blade section and the lower blade section of each blade of the impeller, so that a laminar-flow problem is solved. The upper section and the lower section of each blade are discontinuous, and water shifts in discontinuous gaps to form turbulent flow, so that a cleaning solvent and water are mixed to generate cleaning foams, and therefore, cleaning capacity is improved.
