[0040] In order to have a further understanding and understanding of the features, purposes and functions of the present invention, detailed descriptions are given below in conjunction with the diagrams:
[0041] Please refer to FIG. 5, which is one of the embodiments of the closed impeller of the present invention. The impeller 3 has a disc-shaped structure. There are several radial blades on both sides of the outer edge of the disc. The space between the two adjacent blades constitutes a radial flow channel. The structure of the blade includes a blade inlet 32, a blade side plate 34, a blade outlet 31 and a blade hub plate 36. The central hub of the impeller 3 is provided with a shaft hole 37 The keyway 39 is smoothly combined with the motor shaft center. In addition, there are several ribs 38 connected between the hub and the blade root 30 disc. The axial coordinate of the impeller structure is the z-axis, the radial coordinate is the r-axis, and the blade radial flow The cross...
