How to make copper impeller of water pump

Manufacturing method of copper impeller of water pump;

The copper impeller of the water pump is made of copper and is rarely used. However, it should be possible to manufacture copper impeller by general casting process, but the proportion of copper alloy has also been carefully adjusted, so that the cast copper impeller can meet the requirements in hardness and ductility.

Firstly, the alloy ratio is adjusted by casting, and finally injection molding is carried out.

Extension of knowledge points:

An impeller device comprises serrated rotating blades and a hub for mounting the blades, and is characterized in that the chord length of the blade tip of the rotating blade must be less than 5% of the diameter of the impeller, the serrations are distributed on the rear edge of the rotating blade which is 0.75 to 1.0 times the radius of the rotating blade, and gradually taper from the middle of the teeth to the edge of the teeth, and a saddle-shaped concave surface is formed between two teeth of the tooth root of the pressure surface and the suction surface of the rotating blade. The impeller device can effectively eliminate tip vortex and improve impeller efficiency.
