Description

Technical Field

[0001] This application relates to the field of compressor parts technology, and in particular to a compressor guide ring device. Background Technology

[0002] Guide rings play a crucial role in the operation of compressors. Traditional guide rings typically have a simple structure, which leads to numerous problems in practical use.

[0003] First, the opening size of traditional guide rings is often fixed, making it impossible to flexibly adjust according to actual operating conditions. Under different operating conditions, such as varying pressures, temperatures, and operating durations, the dimensional requirements for the guide ring may change. Guide rings with fixed openings struggle to adapt to these changes, potentially leading to decreased precision in the fit between the guide ring and other internal compressor components. This, in turn, affects the overall performance and operational stability of the compressor, and in severe cases, may even shorten its lifespan. Second, traditional guide rings have poor sound absorption. Compressors generate significant noise during operation, and prolonged exposure to high-noise environments can adversely affect the health of operators.

[0004] The utility model patent with patent application number CN202323086507.7 discloses a novel guide ring for a compressor, including a guide ring body, the guide ring body forming an opening, a positioning groove provided at one end of the guide ring body, and an adjusting block provided at the other end of the guide ring body, the adjusting block cooperating with the positioning groove.

[0005] The aforementioned patent has the following drawbacks: the adjusting block engages with the positioning groove through the locking rod. Under the long-term high-frequency vibration of the compressor, the locking part is prone to loosening due to fatigue, resulting in inaccurate positioning of the guide ring and affecting the operating stability of the compressor. Relying solely on the engagement of the locking rod with the fixed-spaced locking groove, the adjustment accuracy is limited by the spacing of the locking groove, making it difficult to achieve continuous and high-precision adjustment, and failing to meet the application scenarios with stringent requirements for the positional accuracy of the guide ring.

[0006] Therefore, a compressor guide ring device is invented to solve the problems mentioned in the background art. Utility Model Content

[0007] The purpose of this invention is to provide a compressor guide ring device to solve the problems of inconvenient adjustment of the opening size of the existing guide ring, poor reliability of the adjustment structure, and poor sound absorption effect.

[0008] This application provides a compressor guide ring device, which adopts the following technical solution: it includes a guide ring body, wherein the guide ring body has an open ring structure, one end of the guide ring body is provided with a positioning sleeve with internal threads and the other end is connected to a threaded rod adjustment assembly, the threaded rod adjustment assembly is threadedly engaged with the positioning sleeve and is used to adjust the opening size of the guide ring body, the inner ring surface of the guide ring body is provided with a composite sound absorption mechanism, the outer ring surface of the guide ring body is provided with a first wear-resistant layer, and the two opposite sides of the guide ring body are provided with a second wear-resistant layer.

[0009] Optionally, the threaded rod adjusting assembly includes a threaded rod and a fixing block. The fixing block is fixedly connected to the guide ring body, and the threaded rod is rotatably connected to the fixing block. The fixing block has a through hole, and the threaded rod passes through the through hole. The positioning sleeve has a threaded hole inside that matches the threaded rod.

[0010] Optionally, the threaded rod is provided with a limiting component that can limit its movement. The limiting component includes a limiting block with a limiting groove. The limiting block is fixed to the bottom of a fixing block. The threaded rod has several limiting holes. The fixing block is provided with a limiting rod that can pass through the limiting holes and be inserted into the limiting groove.

[0011] Optionally, the composite sound-absorbing mechanism consists of an inorganic foam sound-absorbing base layer, a sound-absorbing fiber transition layer, and a damping material covering layer, from the inside out.

[0012] Optionally, the first wear-resistant layer is made of ceramic matrix composite material, and the second wear-resistant layer is made of tungsten carbide coating.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] 1. The use of a threaded rod adjustment assembly in conjunction with a positioning sleeve with internal threads greatly improves the reliability of adjustment compared to the traditional snap-fit ​​adjustment structure. Under the long-term high-frequency vibration conditions of the compressor, the stability of the threaded fit is stronger and less prone to loosening due to fatigue. This effectively avoids the problem of inaccurate positioning of the guide ring and ensures the operational stability of the compressor. At the same time, the threaded adjustment can achieve continuous and high-precision adjustment, breaking through the limitation of the snap-fit ​​groove spacing on the adjustment accuracy and meeting the application scenarios with stringent requirements for the positional accuracy of the guide ring.

[0015] 2. The composite sound-absorbing mechanism set on the inner ring surface of the guide ring body is composed of an inorganic foam sound-absorbing base layer, a sound-absorbing fiber transition layer and a damping material covering layer. This multi-layer composite structure can absorb the noise generated by the compressor in all directions and at multiple levels, effectively converting and consuming the noise energy, significantly reducing the pollution of noise to the working environment, and effectively protecting the health of the operators.

[0016] 3. The outer ring surface of the guide ring body is made of ceramic matrix composite material as the first wear-resistant layer, and the two opposite sides are made of tungsten carbide coating as the second wear-resistant layer. These two high wear-resistant materials greatly improve the wear resistance of the guide ring, so that the wear degree is significantly reduced during frequent friction contact with other parts. This not only extends the service life of the guide ring, but also reduces the number of maintenance and downtime caused by guide ring wear, and improves production efficiency.

[0022] The present application will be further described in detail below with reference to the accompanying drawings. In the description of the present utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on the present utility model.

[0023] Reference Figure 1 , Figure 2One embodiment shown is as follows: The compressor guide ring device in this embodiment includes a guide ring body 1 with an open annular structure. A positioning sleeve 2 with internal threads is provided at one end of the guide ring body 1, and a threaded rod adjusting assembly 3 is connected to the other end. The connection between the positioning sleeve 2 and the threaded rod adjusting assembly 3 is achieved through threaded engagement, that is, the threaded rod adjusting assembly 3 can rotate in the internal thread of the positioning sleeve 2 and achieve axial movement. A composite sound-absorbing mechanism 4 is fixedly provided on the inner ring surface of the guide ring body 1. This mechanism consists of an inorganic foam sound-absorbing base layer, a sound-absorbing fiber transition layer, and a damping material covering layer from the inside to the outside. A first wear-resistant layer 5 is provided on the outer ring surface, which is made of ceramic matrix composite material. A second wear-resistant layer 6 is provided on both opposite sides, which is made of tungsten carbide coating.

[0024] The implementation principle of the above embodiment is as follows: the guide ring body 1 serves as the main body of the entire device, and its open ring structure can surround the corresponding parts of the compressor. The threaded engagement relationship between the positioning sleeve 2 and the threaded rod adjustment assembly 3 is the key to realizing the adjustment of the opening size. When it is necessary to adjust the opening size, by rotating the threaded rod adjustment assembly 3, the threaded rod adjustment assembly 3 is moved axially relative to the positioning sleeve 2 using the transmission characteristics of the thread, thereby changing the opening size of the guide ring body 1. This threaded engagement method ensures the accuracy and stability of the adjustment and avoids the loosening problem caused by long-term use or vibration. The inorganic foam sound-absorbing base layer in the composite sound-absorbing mechanism 4 utilizes its porous structure to convert some of the energy into heat energy when noise is transmitted, thereby achieving preliminary sound absorption. The fiber structure of the sound-absorbing fiber transition layer can further block and scatter noise, absorbing noise energy; the damping material covering layer utilizes its own damping characteristics to convert the vibration energy of noise into other forms of energy, thereby effectively absorbing the operating noise of the compressor. The first wear-resistant layer 5 on the outer ring surface is made of ceramic matrix composite material. Due to its high hardness and high wear resistance, it can withstand the friction generated when the outer ring surface of the guide ring comes into contact with other parts of the compressor, protecting the outer ring surface from wear; the second wear-resistant layer 6 on the two opposite sides is made of tungsten carbide coating. The high hardness and wear resistance of tungsten carbide can prevent wear on the sides during friction with other parts, ensuring the structural integrity and performance stability of the guide ring body 1 during long-term use.

[0025] Reference Figure 1 , Figure 3 , Figure 4 One embodiment shown is as follows: In this embodiment, the threaded rod adjusting assembly 3 consists of a threaded rod 7 and a fixing block 8. The fixing block 8 is firmly fixed on the guide ring body 1. A through hole 10 is provided on the fixing block 8. The threaded rod 7 passes through the through hole 10 and can rotate in it. At the same time, the positioning sleeve 2 has a threaded hole 9 inside that is adapted to the threaded rod 7, so that the threaded rod 7 can be threadedly connected to the positioning sleeve 2.

[0026] The implementation principle of the above embodiment is as follows: The fixing block 8 serves as a support structure for the threaded rod 7, connecting the threaded rod 7 and the guide ring body 1. Its fixed connection to the guide ring body 1 ensures the integrity of the structure. The threaded rod 7 passes through the through hole 10 on the fixing block 8, allowing it to rotate around its own axis without significant offset or shaking. When the threaded rod 7 rotates, due to its fit with the threaded hole 9 inside the positioning sleeve 2, the threaded rod 7 moves axially within the positioning sleeve 2 under the action of the thread, causing one end of the guide ring body 1 to move relative to the other end, thus adjusting the opening size. The through hole 10 on the fixing block 8 ensures the stability and axial constraint of the threaded rod 7 during rotation, making the adjustment process smoother and more reliable, avoiding decreased adjustment accuracy or structural damage caused by shaking during rotation, and also facilitating the operator's operation of the threaded rod 7.

[0027] Reference Figure 1 , Figure 4 One embodiment shown is as follows: A limiting component 11 is provided on the threaded rod 7 in this embodiment. The limiting component 11 includes a limiting block 12, which is fixed to the bottom of the fixing block 8. A limiting groove 13 is provided on the limiting block 12. At the same time, multiple limiting holes 14 are distributed on the threaded rod 7. A limiting rod 15 is provided on the fixing block 8. This limiting rod 15 can pass through the limiting holes 14 on the threaded rod 7 and be inserted into the limiting groove 13 of the limiting block 12.

[0028] The implementation principle of the above embodiment is as follows: After the opening of the guide ring body 1 is adjusted to the required size by the threaded rod adjustment assembly 3, in order to prevent the threaded rod 7 from rotating due to vibration or other factors during operation, which would cause the opening size to change, the limiting assembly 11 is used for limiting. The limiting rod 15 is inserted into the selected threaded rod 7 limiting hole 14 and inserted into the limiting groove 13 of the limiting block 12. Through this limiting method, the rotational freedom of the threaded rod 7 can be restricted. The limiting block 12 is fixed to the bottom of the fixing block 8, which ensures the stability of the limiting structure. The setting of multiple limiting holes 14 allows the user to select the appropriate limiting position according to different opening adjustment requirements, which improves the flexibility and reliability of the limiting. The limiting rod 15 passes through the limiting hole 14 and is inserted into the limiting groove 13, forming a stable mechanical limiting structure, which ensures that the opening size of the guide ring body 1 is maintained in the set state when the compressor is running, thus ensuring the stable operation of the compressor and the reliable operation of the guide ring.

[0029] Reference Figure 1 , Figure 2 , Figure 3 One embodiment shown is as follows: In this embodiment, the composite sound absorption mechanism 4 on the inner ring surface of the guide ring body 1 is arranged sequentially from the inside to the outside with an inorganic foam sound absorption base layer, a sound absorption fiber transition layer and a damping material covering layer, which are closely fitted to form an integral sound absorption structure.

[0030] The implementation principle of the above embodiment is as follows: When the compressor generates noise, the noise first comes into contact with the innermost inorganic foam sound-absorbing base layer. The porous structure of this base layer causes the noise wave to continuously collide with the pore walls as it propagates within it, converting some of the sound energy into heat energy, thus achieving initial absorption of the noise. Subsequently, the sound-absorbing fiber transition layer, through its internal crisscrossing fiber structure, causes the noise wave to be reflected, refracted, and scattered, further consuming the noise energy. Finally, the damping material cover layer utilizes its own damping characteristics. When the noise wave is transmitted to this layer, the damping material converts the vibration energy of the noise wave into heat energy and other forms of energy, thereby effectively reducing the propagation and diffusion of noise. This achieves multi-level and efficient absorption of compressor noise by the composite sound-absorbing mechanism 4, reducing the impact of the noise generated by the compressor during operation on the environment and operators.

[0031] Reference Figure 1 , Figure 3 One embodiment shown is as follows: the first wear-resistant layer 5 fixedly disposed on the outer ring surface of the guide ring body 1 is made of ceramic matrix composite material, while the second wear-resistant layer 6 fixedly disposed on the two opposite sides is made of tungsten carbide coating.

[0032] The implementation principle of the above embodiment is as follows: During compressor operation, the outer ring surface and two opposite sides of the guide ring body 1 will rub against other components. The first wear-resistant layer 5 of the ceramic matrix composite material on the outer ring surface, with its high hardness, high wear resistance, and high thermal shock resistance, withstands external friction and wear, effectively protecting the outer ring surface of the guide ring body 1 and preventing it from being damaged by friction during long-term use. The second wear-resistant layer 6 of the tungsten carbide coating on the two opposite sides, due to the high hardness and high wear resistance of tungsten carbide, can protect the sides of the guide ring body 1 during contact and friction with other components, preventing wear, scratches, and other problems on the sides, ensuring the structural integrity and guiding performance of the guide ring throughout its use, extending the service life of the guide ring device, and reducing maintenance and replacement costs caused by wear.

[0033] The working principle of this device is as follows: By rotating the threaded rod 7 in the threaded rod adjustment assembly 3, since the fixed block 8 is fixed to the guide ring body 1 and the threaded rod 7 is rotatably connected to the fixed block 8, when the threaded rod 7 rotates, it will rotate in the through hole 10 of the fixed block 8. Since the threaded rod 7 is threadedly engaged with the positioning sleeve 2, and the positioning sleeve 2 is at one end of the guide ring body 1, as the threaded rod 7 rotates, it moves axially in the threaded hole 9 of the positioning sleeve 2, causing one end of the guide ring body 1 to be displaced relative to the other end, thereby achieving precise opening adjustment. After the adjustment is completed, the limiting assembly 11 plays its role. The limiting block 12 is fixed to the bottom of the fixing block 8. Its upper limiting groove 13 cooperates with the limiting hole 14 on the threaded rod 7. The limiting rod 15 is inserted into the limiting groove 13 through the selected limiting hole 14 to restrict the rotation of the threaded rod 7 and ensure the stability of the guide ring opening. The noise generated by the compressor operation is first contacted by the inorganic foam sound-absorbing base layer of the inner ring composite sound-absorbing mechanism 4. The porous structure of the base layer causes the noise wave to collide with the hole wall when it propagates in it, and part of the sound energy is converted into heat energy, thus achieving initial sound absorption. Then, the sound-absorbing fiber transition layer uses its fiber structure to reflect, refract and scatter the remaining noise, further consuming the noise energy. Finally, the damping material covering layer, with its own damping characteristics, converts the vibration energy of the noise wave into other forms of energy, effectively reducing noise propagation and achieving a good sound absorption effect.

[0034] The working principle of this device has been explained through the above embodiments. These embodiments only illustrate several implementation methods of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
