Description

Technical Field

[0001] The present invention relates to the technical field of compressors, and in particular to a sealing structure and a scroll compressor having the same. Background Art

[0002] At present, the compressor is the core equipment of modern industrial pneumatic system, which is a driven fluid machine that boosts low-pressure gas to high-pressure gas. The scroll air compressor is a kind of machine without reciprocating motion mechanism, which mainly relies on scroll to compress air. It has simple structure, small size, light weight and easy to realize automation, so it is widely used.

[0003] However, this scroll compressor still has the following defects when used for compressing gas:

[0004] The scroll compressor drives the movable scroll by the rotation of the transmission shaft, thereby raising the low-pressure gas to high-pressure gas. However, during the operation of the scroll compressor, due to repeated rotation, the end face of the movable scroll and the repeated friction between the sealing strip will cause the following problems: the sealing strip will be displaced under long-term working conditions; long-term friction will cause wear on the top of the sealing strip, and external gas will leak into the scroll compressor; high-frequency rotation will cause vibration, thereby reducing the sealing of the sealing structure and reducing the service life of the body. In this way, the sealing effect of the scroll compressor will be greatly reduced. Especially when compressing high-purity gas, the high-purity gas will be contaminated due to the reduced sealing effect. Summary of the invention

[0005] In view of at least one defect or improvement demand in the prior art, the present invention provides a sealing structure and a scroll compressor having the same, so as to improve the sealing performance of the scroll compressor.

[0010] The two sealing members are directly or indirectly abutted against each other to form a first spacing space;

[0012] The first top surface is used to directly or indirectly contact the first contact surface, and the first cross section is used to directly or indirectly contact the second contact surface, so that the sealing state of the sealing structure is formed by this arrangement.

[0013] The specific shape of the seal has a first top surface and a first cross section with different widths in the direction of arrangement in the first direction, so that when two seals are in direct or indirect contact, a first spacing space can be generated due to the difference in width between the two seals.

[0014] For example, the first top surface of one seal does not contact the first top surface of another seal due to the difference in width, but the first section of one seal directly or indirectly abuts the first section of another seal, and the first section of one seal and the first section of another seal are arranged on the same plane, such as the second contact surface, regardless of whether they are maintained in a facing posture or in a posture opposite to facing, the width difference between the two forms a first spacing space.

[0064] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0065] The terms "first", "second", "third", etc. in the specification and claims of the present invention and the above drawings are used to distinguish different objects rather than to describe a specific order. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusions. For example

[0066] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The described embodiments are only possible technical implementations of the present invention, not all possible implementations. Those skilled in the art can completely combine the embodiments of the present invention to obtain other embodiments without creative work, and these embodiments are also within the scope of protection of the present invention.

[0067] In the prior art of devices that need to be sealed with a sealing structure, the sealing structure in the prior art is a single sealing structure, which is directly placed in the space that needs to be sealed in the device, or a groove is set on one side of the two parts and placed therein. Although this structure can achieve a certain sealing effect, leakage will still occur. In particular, when the two parts are relatively displaced or rotated, the seal will be displaced, and because the two objects will rub against the seal, the seal will be worn and deformed over a long period of time, and then the sealing structure will not be able to achieve a sealing effect.

[0068] like Figure 1 As shown in , in the first embodiment of the present invention, in order to enhance the sealing effect of the sealing structure, improvements are made to the prior art. The present invention is a sealing structure, comprising a plurality of sealing members, the plurality of sealing members are arranged in a first direction, the sealing member has a top surface, and a cross section, the width of the first top surface in the first direction is less than or equal to or greater than the width of the first cross section in the first direction; the top surface of the sealing member is used to form a seal with the first contact surface to form a first end face, so that the two sealing members can be directly or indirectly abutted and installed, and a first spacing space can be formed between the two sealing members; the sealed air cavity is all or part of the first spacing space.

[0069] In this embodiment, there are many ways for the two sealing members to directly or indirectly abut against each other. Taking two sealing members as an example, Figure 2 , Figure 3 , Figure 4 This is a cross-sectional diagram of different abutment modes of seals:

[0070] like Figure 5 As shown in , in the second embodiment of the present invention, the sealing structure includes: a U-shaped sealing unit, wherein the U-shaped sealing unit is arranged singly in the first direction, or a plurality of U-shaped sealing units are arranged directly or indirectly abutting each other, so that the U-shaped space forms a first spacing space. The sealed air cavity is all or part of the first spacing space. The U-shape is its cross-sectional shape, and the cross-sectional shape of the sealing unit is roughly U-shaped, including but not limited to a concave shape, etc.

[0071] The first direction is the direction in which the gas flows in or out, that is, when the top surface of the seal contacts the first contact surface, an air gap is generated between the two due to relative movement, and the gas inside and outside the device will communicate, and the direction in which the gas flows is the first direction. The second direction is roughly the same as the first direction.

[0072] When the sealing structure is arranged in a device to be sealed, the surfaces of the two components of the device to be covered are close to the sealing member, and the surfaces of the two components are similar to Figure 1 , 5The first contact surface and the second contact surface shown in the figure, at the same time, the sealing structure forms a seal of the periphery in a continuous manner on the periphery of a sealing area on the first contact surface; or forms a seal of the periphery in an intermittent overlapping contact manner in the second direction, thereby forming the sealed air cavity into a closed space.

[0073] Furthermore, in order to improve the shock absorption effect of the sealing structure, so that the sealing structure can better adapt and buffer when subjected to pressure or vibration, a tightening component can be provided for the sealing structure of the first and second embodiments of the present invention. When different components of the device are covered, the sealing component tightening component is squeezed and deformed, which can adapt to different pressure changes, play a good shock absorption and sealing effect, and ensure the efficient and stable operation of the required sealing device.

[0074] From the cross-sectional view of the sealing structure, the said tensioning member is arranged between the sealing member and the first contact surface, and its elastic constant is different from that of the sealing member, so that a good shock absorption effect can be achieved. The tensioning member can be integrally formed with the sealing member, that is, the sealing member itself is processed, and various shapes of elastic structures that can play a supporting role are directly processed at the cross-sectional position of the sealing member, which can meet the requirements of having a certain elasticity in the vertical direction, such as cylindrical, serrated, etc. Figure 6 It is a serrated tightening component processed at the bottom of the seal. It can also be two independent components of the sealing structure. The shape of the elastic structure can be any shape, such as a hollow round tube, such as Figure 7 .

[0075] To further facilitate the installation of the sealing structure of the present invention, the sealing structures of the first and second embodiments of the present invention are preferably arranged in the mounting groove. When the sealing structure is arranged in the mounting groove, the cross section of the sealing member contacts the cross section of the mounting groove, i.e., the second contact surface, the top surface of the sealing member contacts the first contact surface, the first sealing member is attached to the first surface of the mounting groove with its side edge, and the last sealing member is attached to the second surface of the mounting groove with its side edge. At the same time, the sealing member is slightly higher than the height of the mounting groove in the depth direction of the mounting groove, such as one tenth to one fifth of the height of the mounting groove. At this time, the sealing member will be compressed in the mounting groove, thereby improving the sealing performance.

[0076] Similarly, the multiple seals used in the present invention will undergo a certain displacement during operation, thereby affecting the sealing effect of the sealing structure. Therefore, in order to solve the above problem, further, a stopper can be added to the sealing structure in Embodiment 1 and Embodiment 2 of the present invention to further fix the seal and prevent the seal from being displaced during operation of the scroll compressor. The stopper can not only be used to separate the seals to form a sealed cavity, but can also be used to fix the seals.

[0077] When the seal is placed between two contact surfaces, the seal is squeezed on both sides, deformed, and fully fills the gap in the installation groove. The seal is close to the two sides and the cross section of the installation groove and the second contact surface, that is, the cross section of the installation groove, and the top surface of the seal is tightly fitted with the first contact surface. Generally speaking, external gas cannot leak inward or outward through the contact part between the seal and the first contact surface and the second contact surface. The seal is tightly fitted when it is difficult to move. At this time, the friction between the seal and the installation groove and the limiter increases, which can effectively reduce the displacement of the seal and play a role in fixing the seal. At the same time, because the seal and the installation groove and the limiter are tightly fitted without gaps, external gas cannot enter the interior, which can also play a good sealing and dustproof effect.

[0078] From the cross-section of the sealing structure, taking the sealing structure of the first embodiment as an example, Figure 8 As shown, a limiter is provided in the first embodiment of the present invention, and the limiter is additionally installed between two sealing members. Similarly, the limiter can also be a raised structure of the second contact surface, that is, the limiter and the second contact surface are integrated. The limiter can be a closed-loop type connected end to end, or a segmented type, wherein the segmented type is a closed-loop type limiter that is disconnected in the middle, with one section being a limiter area and the other section being an unlimited limiter area, and the number of limiters is not limited as long as they play a good fixing role. (The cross-sectional shape of the limiter can be deformed according to the sealing structure).

[0079] Take the sealing structure of the second embodiment as an example. Fig. 9 FIG. 2 shows a situation in which a limiting member is provided in the first embodiment of the present invention, and the limiting member is a protruding structure of the second contact surface.

[0080] In the sealing structure of the scroll compressor of the prior art, the sealing structure is located outside the fixed scroll or the movable scroll. The outside of the disk is the periphery of the meshing area of ​​the rotating roll on the movable scroll of the scroll compressor and the fixed roll on the fixed scroll. Most of them use a single sealing strip placed in the sealing groove to achieve a sealing and dustproof effect. However, when the scroll compressor is working, the movable scroll moves relative to the fixed scroll, and the internal temperature of the entire compressor body is above 150 degrees Celsius. The high temperature will cause the sealing strip and the sealing strip to deform, and the long-term friction movement will cause the sealing strip to shift and wear. When a single sealing groove and a single sealing strip are used, once deformation and wear occur, the external gas will easily leak into the interior of the scroll compressor, and the sealing effect will be reduced. In particular, when the scroll compressor is used for the compression of high-purity gas, once a leak occurs, the high-purity gas will be contaminated and the purity of the final product gas will be reduced.

[0081] Based on this, the inventors have made improvements to the prior art in the third embodiment of the present invention in order to enhance the dustproof sealing effect of the sealing structure. A mounting groove is provided on the disk of the static scroll disk, and one or more mounting grooves may be provided. The mounting groove has a certain width in the first direction, and can be used to install the sealing structure of the first and second embodiments of the present invention. For example, as shown in Figure 10, which is a top view of the static scroll disk, when the first direction is the radial direction of the static scroll disk, the plane shape of the mounting groove is circular, and two are provided outside the static disk, and a mounting groove with a small circumference is provided inside the mounting groove with a large circumference. The shaded portion in the figure is the mounting groove.

[0082] As shown in Figure 11, a protruding structure is provided at the cross-sectional position of the mounting groove, which is provided between the sealing structures and can be used to fix the sealing structure. In the above embodiment, the sealed air cavity can also be inflated by providing a ventilation structure. In this case, a certain amount of gas can be maintained in the sealed air cavity, and the sealing effect can be better achieved. Furthermore, the ventilation structure allows the sealed air cavity to generate a slight positive pressure on the outside of the scroll compressor, and the sealing effect can be further achieved through air pressure. Those skilled in the art can choose whether to add the ventilation structure according to the sealing needs.

[0083] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0084] The above is only an exemplary embodiment of the present disclosure, and the scope of the present disclosure cannot be limited thereto. That is, any equivalent changes and modifications made according to the teachings of the present disclosure are still within the scope of the present disclosure. After considering the specification and practicing the disclosure here, those skilled in the art will easily think of the implementation scheme of the present disclosure. The present invention is intended to cover any variation, use or adaptive change of the present disclosure, which follows the general principles of the present disclosure and includes common knowledge or customary technical means in the technical field not recorded in the present disclosure. The description and examples are regarded as exemplary only, and the scope and spirit of the present disclosure are defined by the claims.

[0085] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0086] It will be easily understood by those skilled in the art that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
