Description

Technical Field

[0001] The utility model relates to the technical field of impeller processing, in particular to a surface finishing processing device for a water pump impeller. Background Art

[0002] The surface finishing of the pump impeller is a key process, which directly affects the corrosion resistance, friction resistance, mechanical strength and overall performance of the impeller. Through grinding, rust, scale, burrs, flash, etc. on the impeller surface can be removed to improve the surface finish of the impeller. This helps to reduce the friction and impact vortex loss between water and the flow channel wall, thereby improving the performance of the water pump.

[0003] The surface grinding of the water pump impeller belongs to the surface finishing treatment. After grinding, the water pump efficiency can be improved and the service life of the impeller can be extended. At present, it is difficult for the impeller grinding device to position the impellers of different models, which will cause the impeller to shift during grinding, thus causing damage to the impeller surface and affecting the effect after grinding. In addition, the current grinding processing device can only grind a single impeller at a time, so the processing efficiency is low. Utility Model Content
