[0002] During pump operation, guide vane assemblies play a crucial role in guiding fluid flow and improving pump efficiency and performance. However, existing pump guide vane assemblies present numerous inconveniences in terms of installation and maintenance, such as complex installation processes, loose component connections, and poor sealing, which affect the overall performance and service life of the pump. Furthermore, existing guide vane guidance methods can only guide fluid through a single mechanism, limiting further efficiency improvements.
[0003] To address the aforementioned issues, we propose an easy-to-install pump guide vane assembly. Utility Model Content

Detailed Implementation
[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 This utility model provides a technical solution: a pump guide vane assembly that is easy to install, including an impeller body 1, an auxiliary guide plate 2, an elastic element 3, and a spline groove 4. Multiple mounting grooves 11 are evenly distributed on the outer circumference of the impeller body 1. One end of the elastic element 3 is connected to the mounting groove 11, and the other end of the elastic element 3 is connected to one end face of the auxiliary guide plate 2. The spline groove 4 is located at the center of the impeller body 1. The elastic element 3 is always in a taut state.
[0021] There are two relatively conventional installation methods for the impeller body 1 and the pump's inner wall. The first method involves an elliptical sidewall where the pump's inner wall contacts the outer circumference of the impeller body 1. Therefore, when the impeller body 1 rotates, the outer end face of the auxiliary guide plate 2 needs to elastically extend and retract with the pump's inner wall. Thus, the elastic element 3 must always be taut to ensure the auxiliary guide plate 2 fits tightly against the pump's inner wall. The second method involves an eccentric arrangement between the impeller body 1 and the pump. This also requires the auxiliary guide plate 2 to extend and retract. Therefore, in summary, the elastic element 3 must always remain taut.
[0022] Furthermore, the auxiliary guide plate 2 includes an auxiliary blade 21 and a supporting guide rib 23. One side wall of the auxiliary blade 21 is connected to the mounting groove 11 through the elastic member 3. The supporting guide rib 23 is provided on the side wall of the auxiliary blade 21 adjacent to the elastic member 3. A sliding groove is provided on the inner side wall of the mounting groove 11. A T-shaped block is provided on the outer side of the supporting guide rib 23. The T-shaped block of the supporting guide rib 23 is slidably connected to the sliding groove of the mounting groove 11.
[0023] Furthermore, the outer end face of the auxiliary vane 21 is provided with multiple rolling elements 22. When the auxiliary vane 21 is ejected, its outer end face will be in close contact with the inner wall of the pump. Therefore, to avoid excessive friction leading to a reduced lifespan of the auxiliary vane 21 and poor flow guiding effect, the rolling elements 22 are added in this invention. In this invention, the rolling elements 22 are made of rubber balls, which can provide shock absorption through elastic deformation and reduce the friction between the auxiliary vane 21 and the inner wall of the pump. It should be noted that the rolling elements 22 cannot be made of excessively soft rubber material, otherwise, the compression of the elastic element 3 will cause damage. Furthermore, a sealing cap 5 is detachably connected to the top surface of the impeller body 1, and a cap spline groove 53 is formed at the center of the sealing cap 5. The cap spline groove 53 communicates with the spline groove 4.
[0024] Furthermore, the sealing cap 5 includes a first assembly cap 51 and a second assembly cap 52, wherein the first assembly cap 51 and the second assembly cap 52 are inserted and assembled.
[0025] Furthermore, the connecting sidewall of the first assembly cover 51 and the second assembly cover 52 is provided with a plug 511, and the end face of the plug 511 is provided with a plug magnet 512. The connecting sidewall of the second assembly cover 52 and the first assembly cover 51 is provided with a slot 521, and a magnet for attracting the plug magnet 512 is provided in the slot 521. The sealing cover 5 adopts a split design, which only requires aligning and inserting the first assembly cover 51 and the second assembly cover 52, and then connecting them with bolts.
[0026] Furthermore, the top surface of the plug 511 is provided with bolt holes, and the top surface of the slot 521 is provided with bolt holes, the bolt holes of the plug 511 communicating with the bolt holes of the slot 521. For example... Figure 2 As shown, the sealing gland 5 is also provided with multiple threaded holes, and as... Figure 1 The impeller body 1 shown has multiple openings on its top surface that correspond to multiple threaded holes on the sealing cover 5, in order to fasten the sealing cover 5 to the impeller body 1.
[0027] Furthermore, the bottom surface of the sealing cap 5 is provided with a sealing strip 54 corresponding to the mounting groove 11. The sealing strip 54 is made of a smooth material to prevent the auxiliary guide plate 2 from failing to slide due to excessive friction. The sealing strip 54 is made of polytetrafluoroethylene (PTFE), which has an extremely low coefficient of friction: PTFE has the lowest known coefficient of friction (only 0.04). The smooth surface of PTFE significantly reduces the frictional resistance between the sealing strip and the contact surface. PTFE has excellent self-lubricating properties, reducing frictional power consumption and wear even under close contact or high-speed movement, extending the service life of the sealing strip. PTFE is compatible with refrigerants, lubricating oils, and impurities, adapting to complex working environments and avoiding increased friction due to chemical corrosion. PTFE does not easily undergo plastic deformation under continuous pressure, maintaining the shape and size stability of the sealing strip and ensuring long-term sealing performance.
[0028] Working principle: First, one end of the elastic element 3 is installed into the mounting groove 11 of the impeller body 1, ensuring that the elastic element 3 is firmly fixed. Then, one side wall of the auxiliary blade 21 of the auxiliary guide plate 2 is connected to the mounting groove 11 through the elastic element 3, while aligning the T-shaped block supporting the guide rib 23 with the sliding groove on the inner side wall of the mounting groove 11, so that the auxiliary guide plate 2 can slide along the sliding groove into place. The multiple rolling elements 22 on the outer end face of the auxiliary blade 21 can reduce friction during rotation, making the installation smoother.
[0029] The first assembly cover 51 and the second assembly cover 52 of the sealing cover 5 are plugged into each other. The plug 511 of the first assembly cover 51 is inserted into the slot 521 of the second assembly cover 52. Since the end face of the plug 511 is provided with the plug magnet 512, and the slot 521 is provided with a magnet for attracting the plug magnet 512, the plug 511 and the slot 521 will be initially fixed under the action of magnetic force. Then, bolts are used to further and firmly connect the first assembly cover 51 and the second assembly cover 52 through the bolt holes on the top surface of the plug 511 and the top surface of the slot 521.
[0030] The installed sealing cap 5 is placed on the top surface of the impeller body 1, ensuring that the sealing strip 54 on the bottom surface of the sealing cap 5 corresponds and fits into the mounting groove 11 of the impeller body 1, thus ensuring a good seal. The sealing cap 5 is connected to the impeller body 1 by bolts, facilitating subsequent maintenance and repair.
[0031] The spline groove 4 at the center of the impeller body 1 and the spline groove 53 at the center of the sealing gland 5 are used to cooperate with the pump's drive shaft to transmit power. During installation, the pump's drive shaft is inserted into the spline groove 4 and the spline groove 53 of the sealing gland to ensure that the impeller body 1 can rotate with the rotation of the drive shaft, thereby realizing the pump's function.
[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
[0033] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
