Abstract
The invention discloses a combined type large silicon carbide ceramic impeller. The combined type large silicon carbide ceramic impeller is formed by splicing a plurality of components including a plurality of first ceramic impeller bodies and a plurality of second ceramic impeller bodies. The first ceramic impeller bodies and the second ceramic impeller bodies are alternately arranged in the circumferential direction; wherein a first blade plate is arranged on the first ceramic impeller body, and a second blade plate is arranged on the second ceramic impeller body; when the first ceramic impeller body and the second ceramic impeller body are spliced, the first blade plates and the second blade plates are spliced to form blades; a first cavity is formed in each blade and extends towards an impeller outlet of the ceramic impeller body along a working surface of the blade; and a splicing line between the adjacent first ceramic impeller body and second ceramic impeller body penetrates through the first cavity. Through the improvement, the reliability of the combined large silicon carbide ceramic impeller is higher.
