Description

Technical Field

[0001] This utility model relates to the field of blower technology, and more specifically, to a multi-stage high-speed blower. Background Technology

[0002] A multi-stage high-speed blower is a mechanical device that gradually increases gas pressure through multiple stages of compression impellers, primarily used in high-pressure gas transportation applications. Its core advantage lies in achieving high-pressure output through multi-stage impellers connected in series, while maintaining a low rotational speed to improve operational stability. Multi-stage high-speed blowers typically employ a centrifugal compressor structure, consisting of multiple impeller units connected in series. After being compressed stage by stage, the gas's kinetic energy is converted into pressure energy by a diffuser, and finally discharged through a volute. The impellers are made of aluminum alloy and precision-machined, effectively reducing vibration and noise.

[0003] In existing technologies, during the use and installation of blowers, the seals at the connection points of multi-stage blowers are prone to loosening, affecting the working efficiency of the blowers; therefore, we have made improvements to this issue and proposed a multi-stage high-speed blower.

It should be noted that, unless otherwise specified, the embodiments, features, and technical solutions in the embodiments of this utility model can be combined with each other.

[0027] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0028] like Figures 1-6As shown, this embodiment proposes a multi-stage high-speed blower, including a multi-stage blower 1. The multi-stage blower 1 has multiple sets of hierarchical linkage rings 2 inside. Each set of hierarchical linkage rings 2 is provided with a connecting threaded component 4, which includes screws and nuts. The outer end of the hierarchical linkage rings 2 is provided with two sets of linkage kits 3. An adjustment component is provided between the two sets of linkage kits 3. The adjustment component is used for adjusting the connection of the linkage kits 3. The adjustment component includes a threaded rod 5 and a threaded cylinder 6 located between the two sets of linkage kits 3. The outer end of the threaded cylinder 6 is provided with a toothed groove 7. The outer end of the toothed groove 7 is engaged with a linkage bevel gear 8. The outer end of the linkage bevel gear 8 is provided with a sliding groove 12. The outer end of the sliding groove 12 is provided with a protective cover 17. A support structure is provided between the linkage bevel gear 8 and the protective cover 17 to stabilize the sliding of the linkage bevel gear 8 on the sliding groove 12. The support structure includes a rotating rod 9 and a limiting ring groove 13 located at the lower end of the linkage bevel gear 8, a positioning ring sleeve 10 and a telescopic rod 11 located at the upper end of the linkage bevel gear 8, and a positioning spring 14 located between the threaded cylinder 6 and the protective cover 17. The inner end of the positioning spring 14 is provided with a positioning cylinder 15, and the movable end of the positioning cylinder 15 is covered with a ring cylinder 16. The ring cylinder 16 is embedded in the inner end of the threaded cylinder 6, and the movable end of the positioning cylinder 15 slides along the inside of the ring cylinder 16. The lower end of the rotating rod 9 is provided with a cross groove for easy connection with a screwdriver.

[0029] The multi-stage blower 1 has multiple sets of interlocking rings 2 arranged axially inside. Adjacent sets of interlocking rings 2 are axially fixed by connecting threaded parts 4, which include matching screw and nut assemblies. Two sets of interlocking components 3 are symmetrically arranged at the outer end of each set of interlocking rings 2, and an adjustment component for adjusting the relative position of the two sets of interlocking components 3 is configured between the two sets of interlocking components 3.

[0030] The adjustment components include:

[0031] The screw adjustment mechanism consists of the threaded rod 5 and the threaded cylinder 6, and the outer end of the threaded cylinder 6 has toothed grooves 7 evenly distributed around the circumference.

[0032] The linkage bevel gear 8 meshes with the tooth groove 7 for transmission;

[0033] The slide groove 12 structure is located at the outer end of the linkage bevel gear 8;

[0034] A protective cover 17 covering the outside of the slide 12;

[0035] The support structure set between the linkage bevel gear 8 and the protective cover 17 is used to ensure the stability of the linkage bevel gear 8 when it slides in the slide groove 12.

[0036] The supporting structure includes:

[0037] The rotating rod 9 and the limiting ring groove 13 are used for axial positioning. The rotating rod 9 is vertically fixed to the lower end of the linkage bevel gear 8, and the outer circumference of its center is provided with an annular limiting ring groove 13. The limiting ring groove 13 forms a snap fit with the inner circumferential surface of the slide groove 12, so that the linkage bevel gear 8 moves axially along the slide groove 12 when rotating.

[0038] The positioning ring 10 and the telescopic rod 11 are used for radial positioning. The positioning ring 10 is fitted onto the outer periphery of the upper end of the linkage bevel gear 8. One end of the telescopic rod 11 is fixed to the outer wall of the positioning ring 10, and the other end is fixed to the inner wall of the protective cover 17, and is arranged parallel to the slide groove 12.

[0039] The positioning spring 14 and positioning cylinder 15 are used for elastic buffering. One end of the positioning spring 14 is fixed to the outer wall of the threaded cylinder 6, and the other end is fixed to the inner wall of the protective cover 17. The positioning cylinder 15 is fitted inside the positioning spring 14, and its movable end is covered with a ring cylinder 16 structure. The ring cylinder 16 is embedded in the inner wall of the threaded cylinder 6, so that the extension and retraction movement of the positioning spring 14 is guided through the ring cylinder 16.

[0040] The slide groove 12 is longitudinally arranged along the lower outer surface of the protective cover 17, and its cross-sectional shape matches the limiting ring groove 13. To facilitate assembly and maintenance, a standard cross groove structure is provided at the lower end of the rotating rod 9 for manual adjustment in conjunction with tools such as screwdrivers.

[0041] In this embodiment, the axial spacing is coarsely adjusted by combining the threaded rod 5 and the threaded cylinder 6, and finely adjusted by combining the linkage bevel gear 8 and the tooth groove 7. The stability of the adjustment process is ensured by the synergistic effect of the support structure. The elastic guiding system composed of the positioning spring 14 and the telescopic rod 11 can effectively absorb the impact load during the adjustment process, and the cooperation between the annular limiting groove 13 and the slide groove 12 ensures the transmission accuracy.

[0042] When using this application: To ensure stable and sealed connections between stages during the installation of a multi-stage blower 1, first, the stage linkage rings 2 are interlocked and fixed together using connecting threaded parts 4. Then, two sets of corresponding linkage kits 3 are wrapped around the outer ends of the stage linkage rings 2. At this point, a screwdriver is used to align with the cross slots in the upper and lower rotating rods 9, and the threaded cylinder 6 is moved into the protective cover 17, ensuring that the inner surface of the ring cylinder 16 is in contact with the outer end of the positioning cylinder 15. At this point, the distance between the ring cylinder 16 and the positioning cylinder 15 is minimized. Then, the rotation of the threaded cylinder 6 is adjusted along the direction of the linkage spring tension. The rotation of the threaded cylinder 6 is achieved by engaging with the linkage bevel gear 8. The rotation of the linkage bevel gear 8 is achieved through the connection between the cross groove on the rotating rod 9 and the screwdriver, which in turn brings the corresponding threaded rod 5 into contact with the corresponding threaded cylinder 6. This causes the screwdriver to rotate in the opposite direction, pushing the threaded cylinder 6 and the threaded rod 5 into a threaded connection, and tightening the corresponding linkage assembly 3 at one end. During this process, the movement of the threaded cylinder 6 is smooth, and a connecting piece is provided between the linkage bevel gear 8 and the threaded cylinder 6 to ensure that the two move and rotate synchronously (e.g., an annular groove is provided on the outside of the threaded cylinder 6, and an arc-shaped slider is provided on the upper end of the linkage bevel gear 8, which can ensure that the movement between the threaded cylinder 6 and the linkage bevel gear 8 is consistent and stable, and that separation will not occur).

[0043] After installation, during use, the connection between each stage cylinder of the multi-stage blower 1 will vibrate. This vibration will cause the stage linkage ring 2 to loosen. This loosening will cause the threaded cylinder 6 and the threaded rod 5 to loosen. At this time, the threaded cylinder 6 will drive the linkage spring connected inside the protective cover 17 (one end of the protective cover 17 is fixed to the outer end of the linkage kit 3) to rotate and contract (the rotational contraction of the linkage spring will reduce the radius of the spring and increase the number of spring coils, thus increasing the unit elastic force of the spring). At the same time as loosening, the threaded cylinder 6 will rebound under the reverse elasticity of the linkage spring, generating a tightening rotational force between the loosened threaded cylinder 6 and the threaded rod 5 (the threaded rod 5 is fixedly connected to one of the linkage kits 3), ensuring that the loosened threaded cylinder 6 and the threaded rod 5 are tightened again, ensuring the stability of the connection seal. This connection seal stability can be carried out automatically, and it ensures that noise generation is reduced during the operation of the multi-stage blower 1.

[0044] It should be understood that in this application, all rotating, sliding, meshing, belt-driven and other moving parts are well lubricated and not prone to slippage or wear, and each part is provided with a corresponding protective shell. However, in the accompanying drawings of this application, the connection state of each moving part is not shown. It should also be understood that all parts in this application are made of metal or plastic materials with suitable strength in the relevant field to ensure that their structural rigidity meets the actual requirements.

Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above.
