The invention relates to a novel manufacturing process of an
impeller. The novel manufacturing process is characterized by comprising the following specific process steps of S1, carrying out 3D printing on an
impeller prototype; S2, manufacturing a
casting system with a riser to form a module; S3, manufacturing a shell; S4, dewaxing and demolding treatment; and S5, carrying out
casting molding. According to the novel manufacturing process of the
impeller, compared with a traditional
casting or
forging method, the method has great advantages that a corresponding mold is needed when the castingor
forging method is used, raw materials and time are wasted, the tedious procedures are omitted through the 3D printing technology, computer related
software can be helped to directly generate the impeller, and any complex impeller can be quickly printed, so that the generation period is shortened, the cost is reduced, the
advantage of greatly reducing the
raw material loss in the research and development process is achieved, meanwhile, the impeller produced by using the process can greatly improve the overall shock absorption and
noise reduction capabilities of a pumping set, actual production reference is provided for the rapid low-pressure
investment casting production process of castings, and the feasibility of the process is verified.
