Description

Noise suppression components and compressors Technical Field

[0001] This invention belongs to the field of air compressor technology and relates to a noise suppression component. Furthermore, this invention also relates to a compressor including such a noise suppression component. Background Technology

[0002] A compressor muffler (also known as a silencer ring, noise reduction ring, or sound insulation ring) is a component used to reduce the noise generated during compressor operation. This muffler is typically installed in the compressor housing near the compressor's discharge or intake port to reduce noise through sound wave absorption, scattering, and damping; therefore, it can also be called a noise suppressor. This muffler is usually mounted into a mounting slot on the compressor housing using components such as elastic retaining rings or wave-shaped retaining rings.

[0003] For example, in the invention patent filed by China North Engine Research Institute (Tianjin) on May 18, 2016, with publication number CN 106015098 and titled "A pre-swirl silencer that effectively widens the compressor flow range", a pre-swirl silencer is disclosed, which includes a compressor volute with a casing treatment, a silencer ring with pre-swirl blades and an elastic retaining ring. The silencer ring is arranged at the inlet of the compressor volute and fixed by the elastic retaining ring.

[0004] This type of muffler ring is fixed to the compressor inlet by a flexible retaining ring. However, assembling the flexible retaining ring is relatively difficult, and there is a risk that it may come loose from the groove if it is not installed properly. On the other hand, mounting components such as wave retaining rings are somewhat expensive because they are not standard parts on the market.

[0005] Therefore, there is a need to improve existing mufflers in order to provide an improved noise suppression device that can overcome one or more of the disadvantages of the prior art. Summary of the Invention

[0006] The purpose of this invention is to reduce the processing cost and installation difficulty of the muffler ring used in the compressor, and to improve the safety of the compressor, while still maintaining the desired noise suppression effect.

[0007] According to one aspect of the invention, a noise suppression member is provided that can be mounted to a mounting groove in the housing of a compressor. The mounting groove extends circumferentially and has a first radial dimension. The noise suppression member may include: a circumferentially extending annular body located radially inside the mounting groove; and an elastic member connected to the annular body, the elastic member including at least one elastic mounting portion protruding radially outward from the annular body to have a second radial dimension, wherein the second radial dimension of the elastic mounting portion is larger than the first radial dimension of the mounting groove, and the elastic mounting portion is elastically deformable, for example, at least radially or axially, so that the noise suppression member is detachably mounted to the mounting groove by means of the elastic mounting portion.

[0008] This noise suppression component can be detachably installed into the mounting slot by means of elastic deformation, without the need for additional parts such as elastic retaining rings, which reduces installation costs and prevents accidental detachment from the compressor housing.

[0009] According to the above aspects of the present invention, preferably, the elastic mounting portion can undergo elastic deformation when it is snapped into the mounting groove, and the noise suppression member can be held in the mounting groove solely by means of the elastic force generated by the elastic deformation.

[0010] In this way, the noise suppression component can be held in the mounting groove by the elastic force generated by elastic deformation, thus forming an elastic self-locking structure, without the need for retaining rings, fasteners or other auxiliary components, reducing the required mounting components and improving reliability.

[0011] According to the above aspects of the present invention, preferably, the mounting groove has a first height in the axial direction, and the elastic mounting portion has a second height in the axial direction, the second height being measured between the highest point of the elastic mounting portion and the lower surface of the annular body, wherein the second height of the elastic mounting portion is greater than the first height of the mounting groove, and the elastic mounting portion is capable of elastic deformation in the axial direction to engage the annular body with the mounting groove.

[0012] This arrangement creates a more reliable self-locking structure, preventing circumferential movement of the annular body and further improving installation reliability.

[0013] According to the above aspects of the present invention, preferably, the elastic member may further include an elastic attachment portion, the elastic mounting portion being connected to the annular body via the elastic attachment portion and protruding from the upper surface of the annular body, forming a radial gap between the elastic member and the annular body.

[0014] This elastic mounting part allows for elastic displacement or deformation in both the radial and axial directions, further improving the reliability of the installation.

[0015] According to the above aspects of the present invention, preferably, the noise suppression element may be made of metal or metal alloy, and the elastic member is formed on the annular body by a stamping process; or the noise suppression element may be made of non-metal, and the elastic member is integrally formed on the annular body by a molding process.

[0016] This noise suppression component can be manufactured as a single piece, thereby reducing material consumption and processing costs, and facilitating rapid mass production.

[0017] According to the above aspects of the present invention, in order to further facilitate the installation and engagement of the noise suppression member into the mounting groove of the compressor housing, preferably, the shape of the resilient mounting portion may include any of the following shapes: flat shape; U-shape; V-shape.

[0018] According to the above aspects of the present invention, preferably, in order to better maintain the balance of the noise suppression member in the mounting groove and improve the noise suppression effect, the annular body may include an outer periphery, and the elastic member includes at least three elastic mounting portions arranged at intervals on the outer periphery.

[0019] According to the above aspects of the invention, preferably, the noise suppression member may further include a pin groove, which is arranged on the annular body spaced apart from the elastic member (e.g., circumferentially spaced).

[0020] This pin-slot arrangement allows for the installation of noise suppression components using tools that mate with the pin slots, further reducing installation difficulty and improving installation efficiency and reliability.

[0021] According to another aspect of the invention, a compressor is provided that may have a housing with an inlet having a mounting groove, wherein a noise suppression element according to the above aspects is provided in the mounting groove.

[0022] This compressor can improve assembly efficiency and reduce compressor costs while ensuring noise suppression.

[0023] According to the above aspects of the present invention, preferably, a first opening may be provided on the periphery of the mounting groove. The first opening has a third radial dimension, which may be larger than the second radial dimension of the elastic mounting portion, so as to allow the elastic member to be installed into the mounting groove via the first opening. This allows the noise suppression member to be installed into the mounting groove more conveniently and quickly.

[0024] At this point, the noise suppression component can be easily and quickly installed into the mounting slot without radial deformation, further improving installation efficiency.

[0025] According to the above aspects of the invention, preferably, the periphery of the mounting groove may further include a second opening arranged circumferentially spaced from the first opening, the second opening being shaped to at least partially accommodate the resilient mounting portion so as to engage the resilient mounting portion in the second opening.

[0026] By locking the flexible mounting part into the second opening, the installation of the noise suppression component can be further facilitated, and after installation, the noise suppression component is prevented from moving accidentally in the circumferential direction, ensuring installation reliability and improving the noise suppression effect.

[0027] Therefore, the noise suppression component of the present invention can meet the usage requirements, overcome the shortcomings of the prior art, and achieve the intended purpose. Attached Figure Description

Detailed Implementation

[0046] It should be understood that, unless explicitly stated otherwise, the invention may employ various alternative orientations and sequences of steps. It should also be understood that the specific apparatus shown in the drawings and described in the specification are merely exemplary embodiments of the inventive concept disclosed and defined herein. Therefore, unless expressly stated otherwise, the specific orientations, directions, or other physical features involved in the various disclosed embodiments should not be considered limiting.

[0047] An air compressor is a device that converts mechanical energy into gas pressure energy. It typically includes reciprocating (piston) compressors, axial compressors, and centrifugal compressors. Centrifugal air compressors use an impeller to drive the gas to rotate at high speed, generating centrifugal force. The gas pressure and velocity are increased during the diffuser flow inside the impeller.

[0048] A centrifugal compressor typically includes a casing, impeller, diffuser, volute, and intermediate body. The casing is a crucial component of the air compressor, usually referring to the outer shell, housing, or casing of the entire compressor. It supports internal components such as the impeller and connects to the intermediate body. The impeller is the core component of the centrifugal compressor; its rotation generates kinetic energy, thereby increasing the pressure and velocity of the gas. The volute, located behind the diffuser and usually downstream of the impeller, collects the airflow from the diffuser, reducing the flow velocity and thus increasing the gas pressure. Additionally, the volute can guide gas outside the compressor, delivering it to gas delivery pipes or coolers. The diffuser, located behind the impeller, converts the kinetic energy of the gas into pressure energy. The intermediate body, also known as the bearing housing, is a key component for maintaining stable, high-speed rotor rotation. It may contain a turbine shaft, floating bearings, thrust bearings, and a fixed shaft seal.

[0049] The casing of a centrifugal compressor may be provided with an inlet end to guide media such as gas evenly to the impeller (e.g., to guide the media axially), reducing airflow disturbance and separation losses.

[0050] Figures 1 and 2 show schematic perspective views of a compressor 1000 according to a non-limiting embodiment of the present invention from different angles.

[0051] As shown in the figure and by way of non-limiting example, the compressor 1000 may include a housing 300 having an inlet 301 and an outlet 302. A medium to be compressed, such as a gas, may enter the compressor 1000 through the inlet 301, and after being compressed by structures such as an impeller, a diffuser, and a volute, exit the compressor through the outlet 302.

[0052] A mounting groove 200 may be provided at the inlet 301 of the housing 300 of the compressor 1000. The mounting groove 200 may extend circumferentially (i.e., extend along the circumferential direction C) and has a first radial dimension R1.

[0053] The first radial dimension R1 can be a dimension measured in the radial direction X. For example, the radial direction X can be the direction passing through the geometric center of the mounting groove 200. For a mounting groove 200 having a generally circular shape, the radial direction X can be its radial direction, and the first radial dimension R1 can be the radius dimension of the mounting groove 200. In this case, the first radial dimension R1 is the distance between the edge profile of the mounting groove 200 facing the center and the center, rather than the distance between the bottom of the mounting groove 200 (i.e., the bottom away from the center) and the center. Therefore, the first radial dimension R1 defines the radial size or cross-sectional size of the inlet channel portion of the inlet 301.

[0054] Figure 3 shows a front view of a compressor 1000 according to a non-limiting embodiment of the present invention.

[0055] As shown in Figures 2 and 3, and as a non-limiting embodiment, a first opening 201 may be provided on the periphery (e.g., the upper periphery) of the mounting groove 200. The first opening 201 may be arc-shaped and have a third radial dimension R3, which may be larger than the first radial dimension R1. The third radial dimension R3 can be measured similarly to the first radial dimension R1 (see Figure 3), i.e., the distance between the edge contour of the first opening 201 and the geometric center of the mounting groove 200. In other words, the third radial dimension R3 is not the radius of curvature or radial dimension of the arc segment itself.

[0056] Additionally, the periphery (e.g., the upper periphery) of the mounting groove 200 also includes a second opening 202 spaced apart from the first opening 201 along the circumferential direction C. As shown in FIG2, the circumferential length of the second opening 202 may be less than that of the first opening 201, that is, the second opening 202 is a smaller opening than the first opening 201.

[0057] Figure 4A shows a cross-sectional view taken through section line AA of compressor 1000 in Figure 3; while Figure 4B shows an enlarged view of a portion of Figure 4A.

[0058] As shown in the figure and as a non-limiting example, the mounting groove 200 may be a stepped groove and include a first groove portion 200A and a second groove portion 200B, such that the mounting groove 200 may have an integral first height h1. This first height h1 may be measured in the axial direction Y.

[0059] The axial direction Y can be the direction in which the airflow enters the compressor 1000 against the flow, and the axial direction Y can be perpendicular to the radial direction X and orthogonal to the circumferential direction C.

[0060] As shown in detail in Figure 4B, the first groove 200A can be further recessed into the circumferential wall of the inlet and has a fourth radial dimension R4, which can be larger than the first radial dimension R1. The fourth radial dimension R4 can be measured similarly to the first radial dimension R1.

[0061] The second groove 200B may have a fifth radial dimension R5, which may be smaller than the fourth radial dimension R4.

[0062] As an example, the fifth radial dimension R5 can be approximately equal to the first radial dimension R1. In this case, when the fifth radial dimension R5 is approximately equal to the first radial dimension R1, the circumferential wall at the inlet 301 of the housing 300 can be considered to have only one groove recessed into the circumferential wall, namely the first groove 200A.

[0063] In the views of Figures 4A and 4B, the wall thickness of the circumferential wall on the left side of the second groove 200B can be less than the wall thickness of the circumferential wall on the right side of the second groove 200B. In other words, the cross-section of the medium flow channel decreases in the direction opposite to the axial direction Y in Figure 4B.

[0064] Figure 5 shows a schematic perspective view of a compressor 1000 equipped with a noise suppression element 100 according to the present invention; while Figure 6 shows a cross-sectional view of the compressor 1000 of Figure 5.

[0065] As shown in the figure, the noise suppression component 100 can be installed into the mounting groove 200 of the housing 300 of the compressor 1000. The noise suppression component 100 may mainly include: a circumferentially extending annular body 10 and an elastic member 20 connected to the annular body 10. The annular body 10 may be located radially inside the mounting groove 200.

[0066] Figure 7 shows a front view of the compressor 1000 of Figure 5; Figure 8 shows a cross-sectional view taken through section line BB of the compressor 1000 of Figure 7; Figure 9 shows a schematic cross-sectional perspective view of a portion of the compressor 1000 according to a non-limiting embodiment of the present invention; and Figure 10 shows an enlarged view of a portion of the compressor 1000 of Figure 9.

[0067] As shown in the figure, the annular body 10 may have a guide surface with a generally arcuate cross-section to make the flow of the medium entering the inlet 301 of the housing 300 smoother, so as to reduce the noise generated.

[0068] As shown more clearly in Figure 10, the annular body 10 abuts against the second groove 200B of the mounting groove 200, while the elastic member 20 extends into and engages in the first groove 200A.

[0069] As an example, in the embodiment of Figures 7-10, the elastic member 20 is engaged in the second opening 202, and preferably, it is elastically engaged therein, that is, the elastic mounting portion 21 of the elastic member 20 undergoes elastic deformation.

[0070] As also schematically shown in Figure 10, the elastic mounting portion 21 has a second height h2 in the axial direction Y, which is measured between the highest point of the elastic mounting portion 21 and the lower surface 14 of the annular body 10.

[0071] Figures 11-15 show different views of a noise suppression element 100 according to a first non-limiting embodiment of the present invention.

[0072] As shown in the figure, the noise suppression component 100 may be generally annular and includes an annular body 10 and an elastic member 20. The annular body 10 may include an outer periphery 11 and an opposing inner periphery 12, as well as an upper surface 13 and an opposing lower surface 14.

[0073] The elastic member 20 may include at least one elastic mounting portion 21. For example, as shown in FIG11, the elastic member 20 includes three elastic mounting portions 21 spaced apart on its outer periphery 11. The elastic member 20 also includes an elastic attachment portion 22, through which the elastic mounting portions 21 are connected to the annular body 10 and protrude from the upper surface of the annular body 10, forming a radial gap between the elastic member 20 and the annular body 10.

[0074] The elastic member 20 is connected to the annular body 10. For example, the elastic member 20 and the annular body 10 can be integrally formed, or the elastic member 20 and the annular body 10 can be formed separately, and the elastic member 20 is connected to the annular body 10 by a connection method such as welding, bonding or riveting.

[0075] As an example where the elastic member 20 is integrally formed with the annular body 10, the noise suppression member 100 may be made of a metal or metal alloy such as aluminum alloy or steel, and the elastic member 20 may be formed on the annular body 10 by a stamping process. As an alternative example, the noise suppression member 100 may be made of a non-metal such as plastic or composite material, and the elastic member 20 may be integrally formed on the annular body 10 by a molding process.

[0076] As shown in Figure 14, the elastic mounting portion 21 protrudes radially outward from the annular body 10, giving the elastic mounting portion 21 a second radial dimension R2. This second radial dimension R2 of the elastic mounting portion 21 can be larger than the first radial dimension R1 of the mounting groove 200. Additionally, the outer periphery 11 of the elastic member 20 can have a sixth radial dimension R6, which can be approximately equal to or slightly smaller than the fifth radial dimension R5, allowing the annular body 10 to be positioned against the second groove 200B of the mounting groove 200 (see Figures 4B and 10).

[0077] This elastic mounting portion 21 can elastically deform, for example, at least radially or axially. Radial deformation can be a relative displacement of the elastic mounting portion 21 toward the center, and as the deformation increases, the corresponding elastic restoring force also increases. Axial deformation can be achieved due to a change in the height of the elastic attachment portion 22 or the elastic mounting portion 21 in the axial direction Y, and similarly, as the deformation increases, the corresponding elastic restoring force also increases.

[0078] As described above with reference to FIG5-10, the noise suppression member 100 can be installed into the mounting groove 200, and specifically, the noise suppression member 100 is installed into the first groove portion 200A of the mounting groove 200 by means of the radial inward deformation of the elastic mounting portion 21.

[0079] As an example of radially deformable detachable installation, during installation, the elastic mounting portion 21 can first be radially deformed inward, and when placed into the mounting groove 200, the elastic mounting portion 21 can elastically return to its original position, so that the outermost radial edge of the elastic mounting portion 21 can abut against the bottom of the first groove portion 200A, thereby holding the noise suppression member 100 in a predetermined position within the mounting groove 200. At this time, the second radial dimension R2 can be greater than the fourth radial dimension R4, thereby ensuring that after installation, the elastic mounting portion 21 still has elastic deformation to keep the noise suppression member 100 in place.

[0080] When it is necessary to remove the noise suppression component 100 from the mounting slot 200, the resilient mounting portion 21 can be deformed radially inward in the same way, thereby allowing it to be removed from the first slot portion 200A of the mounting slot 200, so as to realize the detachable installation of the noise suppression component 100 into the mounting slot 200.

[0081] At this time, the elastic mounting part 21 undergoes elastic deformation when it is inserted into the mounting groove 200, and the noise suppression member 100 can be held in the mounting groove 200 by means of the elastic force generated by the elastic deformation, without the need for additional holding force or holding members (such as fasteners, retaining rings, etc.).

[0082] As described above, “removable installation” as used herein means that the noise suppression component 100 can be installed into or removed from the mounting slot 200 by means of its own elastic deformation, without the need for additional threaded fasteners, adhesives, etc., or welding or riveting to the mounting slot 200.

[0083] As an example of axially deformable detachable installation, the mounting groove 200 has a first height h1 in the axial direction Y, and the elastic mounting part 21 has a second height h2 in the axial direction Y, the second height h2 being measured between the highest point of the elastic mounting part 21 and the lower surface 14 of the annular body 10.

[0084] To ensure that the elastic mounting part 21 undergoes axial elastic deformation after being inserted into the mounting groove 200, the second height h2 of the elastic mounting part 21 is greater than the first height h1 of the mounting groove 200. Thus, when installed into the mounting groove 200, the elastic mounting part 21 can elastically deform in the axial direction Y to engage the annular body 10 with the mounting groove 200.

[0085] As shown in Figures 11-14, the noise suppression component 100 also includes a pin groove 30, which is arranged on the annular body 10 at a distance from the elastic member 20, for example, at a distance along the circumferential direction C, and preferably at equal intervals to achieve better force balance.

[0086] It should be understood that although in the embodiments shown in Figures 11-15 the elastic member 20 and the pin groove 30 are arranged along the outer periphery 11 of the annular body 10, in alternative embodiments the elastic member 20 and the pin groove 30 may also be arranged in other locations, for example, between the outer periphery 11 and the inner periphery 12. Furthermore, although three elastic members 20 and three pin grooves 30 are shown in this embodiment, those skilled in the art will envision a greater number of elastic members 20 and pin grooves 30.

[0087] Figures 16-18 show different views of a noise suppression element 100 according to a second non-limiting embodiment of the present invention.

[0088] Except as described below, the second non-limiting embodiment of the noise suppression element 100 shown with reference to FIG16-18 is substantially the same as or similar to the first non-limiting embodiment of the noise suppression element 100 shown with reference to FIG11-15. Therefore, for the sake of brevity, repeated descriptions of the same or similar parts are omitted, and the same or similar parts are labeled with the same or similar reference numerals.

[0089] In the embodiment of the noise suppression component 100 shown in Figures 11-15, the shape of the elastic mounting portion 21 may be approximately V-shaped or approximately U-shaped; while in the embodiment of the noise suppression component 100 shown in Figures 16-18, the shape of the elastic mounting portion 21 may be approximately flat, in order to achieve different mounting effects or for different compressors 1000.

[0090] Figures 19-20 show different views of a noise suppression element 100 according to a third non-limiting embodiment of the present invention.

[0091] Except as described below, the third non-limiting embodiment of the noise suppression element 100 shown with reference to FIG19-20 is substantially the same as or similar to the first non-limiting embodiment of the noise suppression element 100 shown with reference to FIG11-15. Therefore, for the sake of brevity, repeated descriptions of the same or similar parts are omitted, and the same or similar parts are labeled with the same or similar reference numerals.

[0092] In the embodiment of the noise suppression member 100 shown in Figures 19-20, the elastic mounting portion 21 is attached to the annular body 10 via elastic attachment portions 22 on both sides; while in the embodiment of the noise suppression member 100 shown in Figures 11-15, the elastic mounting portion 21 is attached to the annular body 10 via an elastic attachment portion 22 on one side, such that the elastic mounting portion 21 has a free end.

[0093] Figure 21 shows a cross-sectional perspective view of a compressor 1000 equipped with the noise suppression component 100 shown in Figures 19-20; and Figure 22 shows an enlarged view of a portion of Figure 21.

[0094] As shown in Figures 19-20, the elastic member 20 of the noise suppression component 100 can achieve a greater elastic force. Therefore, the noise suppression component 100 can be more securely held in the mounting groove 200.

[0095] In addition, this noise suppression component 100 can be made of non-metallic materials, such as by molding various composite materials.

[0096] An example installation process for the noise suppression component 100 according to the present invention will now be described.

[0097] As described above, a first opening 201 is provided on the periphery of the mounting groove 200. The first opening has a third radial dimension R3, which is larger than the second radial dimension R2 of the elastic mounting portion 21, so as to allow the elastic member 20 to be installed into the mounting groove 200 through the first opening 201. This installation method allows the noise suppression member 100 to be installed into the mounting groove 200 without elastic deformation in the radial direction X.

[0098] Additionally, as described above, the outer periphery 11 of the mounting groove 200 also includes a second opening 202 arranged spaced apart from the first opening 201 along the circumferential direction C. The second opening 202 is shaped to at least partially accommodate the resilient mounting portion 21. Thus, after the resilient member 20 is installed into the mounting groove 200, the resilient member 20 can be rotated about its own axis, for example, towards the adjacent second opening 202, to engage the resilient mounting portion 21 in the second opening 202.

[0099] The process of removing the noise suppression component 100 from the mounting slot 200 can be the reverse of the installation process described above.

[0100] The terms “upper” and “lower” used herein to indicate orientation or location, and “first” and “second” used to indicate sequence, are merely to enable those skilled in the art to better understand the concept of the invention as illustrated in the preferred embodiments, and are not intended to limit the invention. Unless otherwise stated, all sequences, orientations, or locations are used only to distinguish one element / component / structure from another, and unless otherwise stated, do not indicate any particular order, sequence of operations, direction, or orientation. For example, in an alternative embodiment, “first opening” could be “second opening.”
