[Technical Field]

[0001] This utility model relates to an integrated multi-stage rotor. [Background Technology]

[0002] Water pumps are widely used in industry, agriculture, and daily life, and their stable performance has a significant impact on production and daily life. As one of the core components of a water pump, the rationality of its structural design directly affects the pump's operational quality. The basic structure of a traditional water pump rotor includes a rotor frame, magnetic ring, shaft, and impeller. There is often a gap between the shaft and the rotor frame / impeller. During rotor operation, this often results in loud noise, significant vibration, and radial runout of the rotor body along the shaft, affecting the smoothness of rotor rotation, frequently causing malfunctions, and thus affecting the pump's service life.

[0003] Therefore, this utility model was created based on the above-mentioned shortcomings. [Utility Model Content]

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide an integrated multi-stage rotor with a simple structure and stable operation.

[0005] This utility model is achieved through the following technical solution:

[0006] An integrated multi-stage rotor is characterized by comprising a rotating shaft 1, on which a magnetic ring 2 and a rotor body 3 capable of fixing the magnetic ring 2 are mounted. One end of the rotor body 3 is provided with an impeller 4, and the impeller 4 is provided with a wear-resistant slip ring 5. The two ends of the rotating shaft 1 extend from the ends of the rotor body 3 and the wear-resistant slip ring 5, respectively. The magnetic ring 2, rotor body 3, impeller 4, wear-resistant slip ring 5 and rotating shaft 1 are integrally connected.

[0007] The integrated multi-stage rotor as described above is characterized in that: the rotor body 3 is provided with a plug-in post 31, the impeller 4 is provided with a sleeve part 41 sleeved on the plug-in post 31, the inner wall of the sleeve part 41 is provided with a positioning protrusion ring 42, and one end of the plug-in post 31 is provided with a hook 32 that engages with the positioning protrusion ring 42 after the plug-in post 31 is inserted into the sleeve part 41.

[0010] The integrated multi-stage rotor as described above is characterized in that: the rotor body 3 includes a first positioning block 34 and a second positioning block 35 that are spaced apart on the rotating shaft 1 and cooperate with each other to clamp on both sides of the magnetic ring 2, and the insertion post 31 is disposed on the end of the second positioning block 35.

[0011] The integrated multi-stage rotor as described above is characterized in that: an adhesive is filled between the magnetic ring 2, rotor body 3, impeller 4, wear-resistant slip ring 5 and rotating shaft 1.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1. This utility model integrates the magnetic ring, rotor body, impeller, wear-resistant slip ring and shaft into a single unit, effectively eliminating the gaps between the components and shaft in traditional rotors, greatly reducing the noise and vibration caused by gaps during rotor operation, and improving the smoothness of rotor rotation.

[0014] 2.

Detailed Implementation Methods

[0019] The present invention will be further described below with reference to the accompanying drawings:

[0020] like Figures 1 to 3As shown, an integrated multi-stage rotor includes a shaft 1, a magnetic ring 2 mounted on the shaft 1, and a rotor body 3 for fixing the magnetic ring 2. One end of the rotor body 3 is equipped with an impeller 4, and a wear-resistant slip ring 5 is mounted on the impeller 4. Both ends of the shaft 1 extend from the ends of the rotor body 3 and the wear-resistant slip ring 5, respectively. The magnetic ring 2, rotor body 3, impeller 4, wear-resistant slip ring 5, and shaft 1 are integrated together. This invention effectively eliminates the gaps between the components and the shaft in traditional rotors by integrating the magnetic ring, rotor body, impeller, wear-resistant slip ring, and shaft, greatly reducing noise and vibration caused by gaps during rotor operation and improving the smoothness of rotor rotation.

[0021] Furthermore, the rotor body 3 is provided with a plug-in post 31, and the impeller 4 is provided with a sleeve portion 41 that fits onto the plug-in post 31. The inner wall of the sleeve portion 41 is provided with a positioning protrusion ring 42, and one end of the plug-in post 31 is provided with a hook 32 that engages with the positioning protrusion ring 42 after the plug-in post 31 is inserted into the sleeve portion 41. This structural design allows the rotor body and the impeller to achieve initial positioning through the cooperation of the plug-in post and the sleeve portion. The engagement of the hook with the positioning protrusion ring further prevents relative movement between the two in the axial direction, enhancing the stability of the connection.

[0022] Furthermore, the outer wall of the insertion post 31 is provided with a slot 33, and the inner wall of the sleeve portion 41 is provided with a rib 43 that inserts into the slot 33. The cooperation between the slot and the rib can effectively prevent relative rotation between the rotor body and the impeller in the circumferential direction, thereby further improving the stability of the connection between the two.

[0023] Furthermore, one end of the wear-resistant slip ring 5 is fixedly installed inside the sleeve portion 41 and presses the hook 32 against the positioning protrusion ring 42. The wear-resistant slip ring 5 is made of wear-resistant material, such as ceramic. The wear-resistant slip ring 5 not only reduces the friction between the impeller 4 and other components during rotation, thus improving the service life of the impeller 4, but also, its structural design of pressing the hook 32 against the positioning protrusion ring 42 further enhances the reliability of the connection between the rotor body 3 and the impeller 4, preventing the hook from loosening during long-term operation.

[0024] The rotor body 3 includes a first positioning block 34 and a second positioning block 35 that are spaced apart on the rotating shaft 1 and cooperate to clamp the magnetic ring 2 on both sides. A plug-in post 31 is disposed on the end of the second positioning block 35. The arrangement of the first positioning block 34 and the second positioning block 35 can accurately fix the magnetic ring 2 on the rotating shaft 1, prevent the magnetic ring 2 from moving axially on the rotating shaft 1, and ensure that the magnetic ring can function stably during rotor operation.

[0025] In this invention, adhesive is used to fill the spaces between the magnetic ring 2, rotor body 3, impeller 4, wear-resistant slip ring 5, and rotating shaft 1. The adhesive is a high-strength, high-temperature resistant adhesive, such as epoxy resin. After each component is assembled onto the rotating shaft 1, the adhesive is injected to further enhance the connection strength between the components and the shaft, making the entire rotor a tight whole. This effectively eliminates any gaps that may exist between the components and the shaft, thereby further improving the stability and reliability of the rotor. Specifically, adhesive can be injected between the impeller 4 and the wear-resistant slip ring 5, between the impeller 4 and the rotor body 3, and between the rotor body 3 and the magnetic ring 2.

[0026] During assembly, firstly, the first positioning block 34 is fitted onto the rotating shaft 1, then the magnetic ring 2 is installed on the rotating shaft 1, followed by the installation of the second positioning block 35, which clamps the magnetic ring 2 between the first and second positioning blocks 34 and 35. Next, the sleeve portion 41 of the impeller 4 is fitted onto the insertion post 31 of the rotor body 3, allowing the hook 32 to engage with the positioning protrusion 42, while the protrusion rib 33 is inserted into the slot 43, achieving a preliminary connection between the rotor body 3 and the impeller 4. Then, the wear-resistant slip ring 5 is installed inside the sleeve portion 41, pressing the hook 32 tightly. Finally, adhesive is filled into the gaps between the magnetic ring 2, rotor body 3, impeller 4, wear-resistant slip ring 5, and rotating shaft 1. After the adhesive cures, the entire rotor forms a tight, integrated structure. Through the above structural design, this integrated multi-stage rotor effectively solves the problems existing in traditional water pump rotors, possessing advantages such as low noise, low vibration, smooth rotation, and long service life, making it suitable for various water pump equipment.
