Embodiment Construction
[0013] Such as figure 1 and figure 2 As shown, the compressor impeller of the present invention includes a wheel disc 1, which is a disc with a shaft hole 5 processed in its center and a shaft sleeve 4 arranged in the center of one side. The inner diameter of the bushing 4 is equal to and corresponds to the shaft hole on the wheel disc 1 . The shape of the sleeve 4 is trumpet-shaped, so that the diameter of one end thereof is larger than that of the other end. The big end of the axle sleeve 4 is cast integrally with the wheel disc 1 . Blades are evenly distributed around the shaft sleeve 4, and the blades and the shaft sleeve 4 are cast as one. One end of the short blade 3 far away from the wheel disk 1 is retracted inward, and the retracted length is 1 / 5 of the total length of the blade, so that the length of the blade on the end of the shaft sleeve 4 far away from the wheel disk 1 is arranged in a long and short end shape. Among the adjacent blades, one impeller is a lo...
