At present, impeller manufacturing mainly comprises 2 processing modes, namely:
casting and traditional machining, the method is the mainstream impeller manufacturing method at present, firstly, an integral impeller is manufactured through a casting mould, and then, the outer surface of the impeller is finished through equipment such as a numerical control lathe, a milling machine and the like. The main difficulty of the process is that the casting defects (such as air holes, sand holes, insufficient casting and the like) cause the lower yield, and the inner flow passages of the blades between the cover plates cannot be machined and polished due to the interference of the upper cover plate and the lower cover plate of the impeller, so that the surface of the inner flow passages is rough, and the working efficiency and the service life of the impeller are further reduced;
according to the method, three-dimensional model and point position data of the impeller are imported through powder paving/feeding type 3D printing equipment, and one-time printing and forming are carried out through a laser direct forming technology (DMD), however, due to the fact that the closed impeller is provided with a structural cover plate and blades, excessive support is achieved during design, powder materials are wasted, support removing is difficult and time consuming, and the surface accuracy of an internal runner after polishing treatment is affected.
