[0021] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0022] A vortex pump impeller, reference Figure 1 and Figure 2 As shown, it includes a wheel rim 1 and a wheel axle 2 integrally formed at the center of the wheel rim 1. The wheel rim 1 and wheel axle 2 are coaxially arranged. The wheel axle 2 is provided with a mounting shaft hole 3 and a flat keyway is provided in the mounting shaft hole 3. The vortex pump impeller can be assembled onto the pump shaft through the mounting shaft hole 3.

[0023] Blades 4 are provided on both axial end faces of the wheel rim 1. The blades 4 are evenly distributed on the wheel rim 1 and extend along the radial direction of the wheel rim 1. The outer end of the blade 4 is flush with the outer edge of the wheel rim 1.

[0024] The blades 4 on the two axial end faces of the wheel rim 1 are distributed in a mirror symmetrical manner with the wheel rim 1 as the center. The angle α between each blade 4 and the wheel rim 1 is deflected in the impeller rotation direction. In one embodiment, the angle α between each blade 4 and the wheel rim 1 is deflected in the impeller rotation direction by 15°-30°. Preferably, the angle α between each blade 4 and the wheel rim 1 is deflected in the impeller rotation direction by 20°.

[0025] Therefore, the two blades 4 on the two axial end faces of the wheel rim 1 are arranged in a V-shape. If the two blades 4 are a group of blades 4, the two blades 4 in all the groups of blades 4 on the wheel rim 1 are arranged in a V-shape.

[0026] Reference Figure 1 and Figure 3 As shown, a mounting ring 5 is integrally formed on the wheel rim 1. The mounting ring 5 protrudes from the two axial end faces of the wheel rim 1. The mounting ring 5 is coaxially arranged with the wheel rim 1. A mounting part is formed between the mounting ring 5 and the edge of the wheel rim 1. All blades 4 are evenly distributed on the mounting part. The inner end of the blade 4 is flush with the mounting ring 5, and the outer end of the blade 4 is flush with the outer edge of the wheel rim 1. The height of the blade 4 is the same as the height of the mounting ring 5.

[0027] Among them, the two axial end faces of the mounting part are formed with arc-shaped surfaces 6. The arc-shaped surfaces 6 extend from the top of the mounting ring 5 to the outer edge of the wheel rim 1. The cross-section of the arc-shaped surfaces 6 gradually decreases from the mounting ring 5 to the outer edge of the wheel rim 1.

[0028] This application addresses the efficiency and energy consumption issues of vortex pumps by changing the shape of the blades 4 in the impeller. The angle of the blades 4 is deflected in the direction of blade rotation, forming a structure similar to a paddle shape. This allows the fluid to be guided more smoothly into the flow channel of the vortex pump, improving the velocity distribution of the fluid within the impeller flow channel.

[0029] Compared with conventional impellers, the vortex pump impeller of this application can generate stronger longitudinal and radial vortices at the same rotational speed, and the energy loss caused by the blade 4 is smaller. Therefore, the pressure range generated is wider, which can significantly improve the kinetic pressure of liquid flow in the vortex pump, thereby improving the head and efficiency of the vortex pump and reducing the energy consumption of the vortex pump.

[0030] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
