AI Technical Summary
Existing technologies for manufacturing titanium alloy three-dimensional flow impellers suffer from low material utilization, long processing cycles, and high costs. Furthermore, the thermal deformation and stress concentration problems caused by the welding process severely affect the dynamic balance performance and reliability of the impeller.
The blade structure is divided into two parts, an inner concave part and an outer convex part, which are manufactured and processed separately. Metallurgical connection is achieved through 3D printing and precision machining technology. Combined with the oblique insertion connection of the oblique slot and the card body, the filling of the through hole and the fitting design of the annular groove, the boundary line is optimized to improve the connection stability and hydrodynamic performance.
This achieves efficient use of materials, reduces processing difficulty and cost, improves the connection stability and hydrodynamic performance of the impeller, and ensures overall efficiency and reliability.
