Description

Technical Field

[0001] The present invention relates to a rotary compressor, and more particularly to an elastic damping bracket for a compressor accumulator and a compressor system. Background Art

[0002] A compressor is a driven fluid machine that raises low-pressure gas to high-pressure gas, and is the heart of a refrigeration system. It sucks in low-temperature and low-pressure refrigerant gas from the suction pipe, compresses it by driving a piston through the operation of an electric motor, and then discharges the high-temperature and high-pressure refrigerant gas to the exhaust pipe, providing power for the refrigeration cycle. An accumulator is one of the important components of a compressor, which plays the roles of storage, gas-liquid separation, filtration, silencing, and refrigerant buffering.

[0003] The accumulator is usually installed on the compressor housing through an accumulator bracket. The existing accumulator brackets are mainly in two forms: clamp and welding. Among them, the clamp-type accumulator bracket has a high damping coefficient, small vibration and noise, but its cost is high; while the welded-type accumulator bracket has a low cost, but at the same time, it has the defects of low damping coefficient and lack of buffering ability.

[0004] For example, a disclosed accumulator bracket and a compressor including the same in CN114427767A. The accumulator bracket in it is still fixed to the outer side wall of the compressor body and the accumulator by welding. Although it is provided with a clamp, in this solution, the clamp is arranged around the accumulator to limit the vibration and noise radiation of the accumulator, and it is difficult to weaken the transmission of vibration; and the clamp needs to be arranged around the accumulator, occupying a large space and having a high cost.

[0005] Therefore, it is necessary to design an accumulator bracket that can combine the advantages of the clamp form and the welding form, while improving the damping coefficient of the accumulator bracket, and also reducing the cost of the accumulator bracket. Summary of the Invention

[0006] The purpose of the present invention is to provide an elastic damping bracket for a compressor accumulator and a compressor system to solve at least one of the above problems, so as to solve the defects that the clamp form of the existing accumulator bracket has a high cost and the welding form lacks buffering ability. The elastic damping bracket of the present invention realizes the effect of reducing the cost of the bracket while improving the damping coefficient of the welded bracket through the combination of rigidity and elasticity.

[0007] The purpose of the present invention is achieved through the following technical solutions:

[0008] The first aspect of the present invention discloses an elastic damping bracket for a compressor accumulator, including a first welding bracket, a second welding bracket, and a buffer member;

[0009] The described buffer is abutted and arranged between the first welding bracket and the second welding bracket, and the first welding bracket, the buffer, and the second welding bracket are sequentially assembled through connecting pieces.

[0010] Preferably, the buffer is an energy-consuming damper.

[0011] Preferably, the buffer is formed by sequentially laminating a plurality of arc-shaped spring pieces.

[0012] Preferably, the second welding bracket is provided with an installation groove, and the buffer is arranged in the installation groove.

[0013] Preferably, both ends of the buffer are abutted against the inner side wall surface of the installation groove, the middle of the buffer arches up, and the arch top abuts against the first welding bracket.

[0014] Preferably, the first welding bracket, the buffer, and the second welding bracket are connected by threads.

[0015] Preferably, the connecting piece includes a first threaded piece and a second threaded piece. The first threaded piece includes a screw rod and a bolt, and the second threaded piece includes a nut.

[0016] Preferably, the elastic damping bracket is an axisymmetric structure.

[0017] Preferably, the second welding bracket includes supporting sections on both sides and a welding section connecting the two supporting sections on both sides; there is a pair of the first welding brackets and the buffer, and the first welding brackets and the buffer are assembled on the supporting sections of the second welding bracket through connecting pieces.

[0018] The second aspect of the present invention discloses a compressor system, including a compressor and a liquid receiver, and the elastic damping bracket as described above is used to connect the compressor and the liquid receiver;

[0019] The first welding bracket is fixedly welded to the liquid receiver;

[0020] The second welding bracket is fixedly welded to the compressor.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] By welding the first welding bracket on the liquid receiver, welding the second welding bracket on the compressor, and arranging a special buffer (elastic damping component) between the first welding bracket and the second welding bracket, the damping coefficient and energy consumption coefficient of the elastic damping bracket can be effectively improved, and the overall bracket is constrained in the form of threaded connection, which can increase the transmission loss in the high-frequency band, optimize the vibration of the liquid receiver, and reduce noise.

[0023] An energy-dissipating damper is adopted, preferably an energy-dissipating damper formed by laminating several arc-shaped spring pieces, as a buffer member abutted between the first welding bracket and the second welding bracket. When vibration occurs, the arc-shaped spring pieces undergo elastic deformation to absorb the vibration energy. At the same time, the force-bearing processes of the various layers in the multi-layer arc-shaped spring pieces are not exactly the same, resulting in deformation and friction between the layers, thereby dissipating energy and reducing the vibration energy, and finally achieving the vibration reduction effect of the elastic damping bracket.

[0027] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] Embodiment

[0029] An elastic damping bracket for a compressor liquid receiver, as Figure 1 and Figure 2 shown, includes a first welding bracket 1, a second welding bracket 2 and a buffer member 3;

[0030] The buffer member 3 is abutted and arranged between the first welding bracket 1 and the second welding bracket 2, and the first welding bracket 1, the buffer member 3 and the second welding bracket 2 are sequentially assembled through a connecting member 4.

[0031] More specifically, in this embodiment:

[0032] As Figure 1 、 2 shown, the overall elastic damping bracket is an axisymmetric structure. The second welding bracket 2 is an integral structure, as Figure 2 , and is composed of two side support sections and a middle welding section; the welding section adopts an arc shape adapted to the radian of the compressor welding surface, and the support sections are respectively used to connect the buffer member 3 and the first welding bracket 1. The first welding bracket 1 is provided in a pair, as Figure 1 shown, and is respectively connected to the support sections on both sides of the second welding bracket 2 through a connecting member 4; the buffer member 3 corresponding to the first welding bracket 1 is also provided in a pair and is abutted between the second welding bracket 2 and the first welding bracket 1.

[0033] The buffer member 3 adopts an energy-consuming damper and can achieve vibration reduction by means of damping energy consumption. In this embodiment, the buffer member 3 is further formed by sequentially laminating a plurality of arc-shaped spring pieces. The stacking method, stacking layers, thickness of a single arc-shaped spring piece, wave pitch, and selected material need to be optimized by simulation and testing according to actual conditions and requirements. Installation grooves 5 are respectively formed on the support sections on both sides of the second welding bracket 2, as Figure 1 , and the buffer member 3 is arranged in the installation groove 5, and both ends thereof abut against the inner wall surface of the installation groove 5; since the buffer member 3 is arched, the arched portion in the middle thereof protrudes from the second welding bracket 2, and the top of the arch also abuts against the first welding bracket 1.

[0034] In the elastic damping bracket, the first welding bracket 1, the buffer member 3, and the second welding bracket 2 are assembled into a whole by means of threaded connection. Correspondingly, the connecting member 4 is a threaded member, specifically including a first threaded member and a second threaded member. Among them, the first threaded member can be a screw rod or a bolt and can be selected according to actual conditions; the second threaded member uses a nut to lock the whole elastic damping bracket. In this embodiment, a long bolt is adopted. After passing through the first welding bracket 1, the buffer member 3, and the second welding bracket 2 in sequence from the upper top surface of the first welding bracket 1, it is locked by a nut through the lower top surface of the second welding bracket 2. The bolt passes through the top of the arch (the axis of symmetry) of the buffer member 3, so that the force deformation of the arc top of the arc-shaped spring piece is more uniform.

[0035] In a compressor system adopting this elastic damping bracket, especially in a rotary compressor, this elastic damping bracket is connected between the compressor and the liquid receiver. Further, this elastic damping bracket is fixedly welded to the outer wall surface of the liquid receiver through the first welding bracket 1 and is fixedly welded to the compressor through the second welding bracket 2. When the liquid receiver vibrates, the buffer member 3 absorbs the vibration based on the damping energy absorption effect, and at the same time, a movement to overcome the vibration will also be generated based on the damping effect, that is, the force application processes of the various layers in the set of multi-layer arc-shaped spring pieces are not completely the same, resulting in deformation and friction between the layers, and then energy dissipation occurs, and the vibration energy is reduced, and finally the vibration reduction effect of the elastic damping bracket is achieved.

[0036] The above description of the embodiments is for the convenience of those of ordinary skill in the art to understand and use the invention. It is obvious that those skilled in the art can easily make various modifications to these embodiments and apply the general principles described herein to other embodiments without creative labor. Therefore, the present invention is not limited to the above embodiments, and the improvements and modifications made by those skilled in the art without departing from the scope of the present invention according to the disclosure of the present invention should be within the protection scope of the present invention.
