Description

Technical Field

[0001] This utility model relates to the field of pipeline pump equipment technology, specifically to a pipeline pump impeller assembly that is easy to install. Background Technology

[0002] According to publication number CN221144818U, the patent title is: "A Pipeline Pump Impeller Mounting Assembly". The assembly includes an impeller pump, a motor, and an impeller. The motor's output end is connected to a main shaft extending into the impeller pump and engaging with a connecting post on the impeller to drive its rotation. An mounting ring is provided between the main shaft and the impeller, connecting to both the main shaft and the impeller. During installation, the mounting ring, connecting post, and main shaft require fine adjustments. Since the internal space of an impeller pump is typically small, this adds extra difficulty to adjusting the mounting ring. Therefore, we propose a pipeline pump impeller assembly that is easy to install. Utility Model Content

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Refer to the attached Figure 1-6An easy-to-install pipeline pump impeller assembly includes a concentrically arranged impeller 1, mounting ring 2, and main shaft 3. The impeller 1 is also equipped with a connecting post 11 and a square truncated pyramid 13. The design of the square truncated pyramid 13 allows for a precise insertion fit with the square groove 32 on the inner wall of the main shaft 3. This square fit is more resistant to torsional and shear forces than circular or other shaped fits, thus significantly improving the connection stability between the impeller 1 and the main shaft 3. Furthermore, the geometry of the square truncated pyramid 13 restricts the degrees of freedom during assembly, allowing for more precise alignment of the impeller assembly and reducing assembly errors. A mating post 14 connects the main shaft 13 to the connecting post 11. The mating post 14 is inserted into the square groove 32, which not only improves the connection strength but also increases the overall stability of the component, thereby extending the service life of the pipeline pump. The protruding teeth 31 on the main shaft 3 are engaged in the mounting ring 2, so that the whole is inserted into the connecting post 11. This fit design makes the assembly process simpler, reduces complex assembly steps, and improves assembly efficiency. The square groove 32 on the inner wall of the main shaft 3 is inserted into the square truncated pyramid 13 to install the connecting post 11 and the square truncated pyramid 13. These structures provide a foundation for the stable connection of the components.

[0024] The connecting post 11 has a connecting groove 12 for accommodating the mounting ring 2. The mounting ring 2 has a flange 23 around its circumference that engages with the connecting post 11. The flange and the connecting groove 12 of the connecting post 11 achieve a precise engagement, ensuring the secure assembly of the impeller assembly.

[0025] The protruding teeth 31 on the main shaft 3 correspond to the recessed mounting grooves 22 on the mounting ring 2. This design makes the installation of the impeller assembly more precise and reduces errors during the installation process. The shaft center of the mounting ring 2 has a through hole 21, which allows it to slide upwards, facilitating quick positioning and installation during maintenance and impeller replacement. During installation, the mounting ring 2 is sleeved from the tail of the main shaft 3. The mounting grooves 22 on the mounting ring 2 correspond to the protruding teeth 31. The protruding teeth 31 are engaged in the mounting grooves 22 and abut against the bottom wall of the mounting ring 2 to form a whole. This installation method greatly improves maintenance efficiency.
