Description

Technical Field

[0002] The description in this section merely provides background information related to the disclosure of the present utility model and does not constitute prior art.

[0003] The scroll compressor is a type of positive displacement compressor, and the compression components consist of a moving scroll and a stationary scroll. It is widely used in the fields of chemical industry, refrigeration, air separation, oil and gas, and has many advantages such as high efficiency, energy saving, and stability. However, the compression process of the scroll compressor is uneven, which will produce periodic pressure pulsation and torque fluctuations, causing the compressor to vibrate. In addition, the scroll compressor operates at a high speed, and the gap between the scroll main units is very small. If impurities or liquids enter, it will cause wear or jamming of the scroll main unit, causing severe vibration of the compressor. If the vibration reduction is not good, the vibration of the compressor will be transmitted to the installation foundation and surrounding equipment, causing noise pollution and equipment damage. At the same time, the vibration of the compressor will aggravate the wear of the scroll main unit, reduce the life and efficiency of the compressor, and even shut down failures, and further affect output, causing great economic losses.

[0004] The existing vibration reduction treatment for scroll compressors is generally performed by opening a first hole below the support at the bottom of the compressor and reducing vibration through an elastic mechanism, but the effect is often unsatisfactory, and the vibration reduction unit is generally an integrated fixed structure, which is difficult to maintain and replace when a failure occurs, and the production cost is also high.

The following describes the implementation method of the present utility model based on its overall structure.

[0029] See also Figure 1-3 , is a scroll compressor vibration reduction mechanism of this embodiment, used to support the compressor, including:

[0030] A body 1, wherein the body 1 has a first side and a second side opposite to each other, wherein the first side of the body 1 is used to connect with a support column 100;

[0031] At least one first buffer device 2, the first buffer device 2 extends from the body 1 into the support column 100 and is used to conflict with the support column 100;

[0032] At least one second buffer device 3 , wherein the second buffer device 3 extends from the body 1 toward a direction away from the support column 100 .

[0033] By means of the above structure, the main body 1 in this embodiment includes two-stage vibration reduction at the top and bottom. Compared with the traditional one-stage vibration reduction, this embodiment significantly improves the vibration decomposition effect of the compressor, thereby reducing the environmental noise and mechanical wear caused by the vibration.

[0034] Furthermore, the first buffer device 2 includes a first limit seat 21, a first buffer pad 22 and a first limit column 23; the first limit seat 21 is configured to be tubular, the first limit seat 21 is inserted into the first hole 11, and the outer wall of the first limit seat 21 fits with the inner wall of the first hole 11, and the inner wall diameter of the first limit seat 21 is larger than the diameter of the support column 100; the first buffer pad 22 is configured to be annular, the first buffer pad 22 is placed at the bottom of the first hole 11, and the edge of the first buffer pad 22 is in conflict with the inner wall of the first limit seat 21; one end of the first limit column 23 is in conflict with the first hole 11, and the diameter of the first limit column 23 is smaller than the inner diameter of the hole; the second buffer device The device 3 includes a second limiting seat 31, a second buffer pad 32 and a second limiting column 33; the second limiting seat 31 includes a tube portion 311 and an annular portion 312 arranged at one end of the tube portion 311, the tube portion 311 is inserted into the second hole 12, and the outer wall of the tube portion 311 matches the inner wall of the second hole 12, the second buffer pad 32 includes a peripheral portion 321 and a seat portion 322 arranged at one end of the peripheral portion, the annular portion 312 abuts against the seat portion 322, the peripheral portion 321 is inserted into the tube portion 311, and the outer wall of the peripheral portion 321 abuts against the inner wall of the tube portion 311; the second limiting column 33 is inserted into the peripheral portion 321, and the inner wall of the peripheral portion 321 abuts against the outer wall of the second limiting column 33.

[0035] When using this embodiment, the staff only needs to fix and stabilize the multiple second buffer devices 3 on the main body 1 and the external frame 200, align the support column 100 at the bottom of the compressor with the position of the first buffer device 2 in the first hole 11, and insert the multiple support columns 100 into the first buffer device 2, so that the hollow support column 100 can be sleeved on the first limiting column 23 of the first buffer device 2. At this time, the first limiting seat 21 and the first limiting column 23 respectively limit the inner and outer walls of the support column 100. At the same time, one end of the support column 100 also abuts against the flexible first buffer pad 22 made of rubber. After the compressor is running, if the compressor vibrates When the compressor moves, the vibration can be transmitted to the support column 100 at the bottom of the compressor, wherein some small-amplitude vibrations can be squeezed by the flexible first buffer pad 22, and the potential energy of the vibrations can be converted into the elastic deformation of the first buffer pad 22 itself, and finally offset, and some large-amplitude vibrations continue to be transmitted to the first limit seat 21, the first buffer pad 22 and the first limit column 23 on both sides of the support column 100 and transmitted to the main body 1, and continue to be transmitted from the main body 1 to the second limit seat 31 in the second hole 12. At this time, the second buffer pad 32 tightly attached to the second limit seat 31 absorbs most of the residual vibration and continues to convert the vibration potential energy into elastic deformation, thereby realizing the elimination of the vibration generated by the compressor.

[0036] During the use of this embodiment, since the vibration of the compressor is firstly eliminated in the first buffer device 2, and the eliminated vibration is further eliminated in the second buffer device 3, compared with the traditional single-stage shock-absorbing support structure that only eliminates a single vibration, a higher noise reduction effect is achieved, and the vibration caused by large vibration is avoided from being transmitted to the installation foundation and surrounding equipment, causing noise pollution and equipment damage, thereby extending the life and efficiency of the compressor. At the same time, since the first buffer device 2 and the second buffer device 3, which are the core of the secondary shock absorption, are composed of multiple split structures and can be quickly disassembled and installed without special tools, compared with the traditional integrated structure, the split-structure secondary shock absorption component of the utility model can effectively improve the later maintenance efficiency of the vibration reduction mechanism of the scroll compressor.

[0037] Furthermore, if Figure 1 and Figure 3 As shown, the body 1 is configured as a conventional rectangular plate structure, and the plate structure of the body 1 is slightly raised from the four sides to the middle to enhance the structural support force, and the position of the first hole 11 on the body 1 is prefabricated according to the specific compressor model. In this embodiment, Figure 1 As shown, the first hole 11 is arranged in an isosceles triangle mirror image along the main body 1. The above arrangement can effectively achieve a balance of stability, and the second hole 12 is located at the corner of the rectangle of the main body 1 to achieve the most stable support effect for the main body 1. In actual use, the main body 1 can be installed on the external frame 200 through the combination of the second hole 12 and the second buffer device 3, and screwed into the second limit column 33 by bolts, and can also be installed in any other area where the compressor mechanism is required. The first limit seat 21 in the first buffer device 2 is set to be an annular cylindrical shape, and the bottom of the first limit seat 21 has a small amount of protruding base structure, which contacts the bottom surface of the first hole 11, which helps to enhance the stability of the first limit seat 21 in the first hole 11. The length of the first limit seat 21 matches the depth of the first hole 11, so that the first limit seat 21 protrudes out of the first hole 11. It is worth noting that the collective outer contours of the first buffer pad 22 and the first limiting column 23 are both set to a matching circular or cylindrical structure, so that the force of the first buffer device 2 after vibration can be more balanced. The first buffer pad 22 is sleeved on the outer annular area at the bottom of the first limiting column 23. Therefore, after being fixed, the support column 100 can fall on the first buffer pad 22 in the annular area, so that a better vibration reduction effect can be achieved.

[0038] In another embodiment, the first buffer pad 22 in the first buffer device 2 can cover the bottom of the first limiting column 23, that is, the first limiting column 23 and the support column 100 are jointly abutted against the first buffer pad 22 of the flexible structure. At this time, the first buffer device 2 can also obtain better shock absorption effect by absorbing kinetic energy of a larger area of ​​flexible components.

[0039] Furthermore, the tube portion 311 of the second limit seat 31 is also configured as a cylindrical structure that matches the inner wall of the second hole 12, and the peripheral portion 321 of the second buffer pad 32 and the second limit column 33 are configured as a whole as circular or cylindrical structures that match each other, so that the force on the second buffer device 3 after vibration can be more balanced.

[0040] Furthermore, if Figure 2 As shown, the number of combinations of the support column 100, the first hole 11 and the first buffer device 2 is three groups, and the three groups of combinations of the support column 100, the first hole 11 and the first buffer device 2 are arranged in an isosceles triangle on the body 1 in a mirror-image arrangement. At the same time, the number of combinations of the second hole 12 and the second buffer device 3 is four groups, and the four groups of combinations of the second hole 12 and the second buffer device 3 are arranged at the four corners of the body 1. Specifically, the pressure from the compressor and the vibration transmitted to the body 1 of the vibration reduction mechanism can be more evenly dispersed through the mirror-symmetric triangular arrangement of the first buffer device 2 and the quadrilateral arrangement of the second buffer device 3.

[0041] Furthermore, if Figure 1 As shown, the second limiting column 33 includes a fixing hole 331, and the fixing hole 331 is fixed to the external frame 200 by means of a mounting bolt. The fixing hole may be an internal thread structure in another embodiment, but in this embodiment, it is a conventional cylindrical structure space for inserting and fixing the fixing member on the external frame 200, thereby locking the body 1.

[0042] Furthermore, the main body is made of nylon and 50% glass fiber. Specifically, the main body 1 is injection molded and weighs 490g. In the first buffer device 2 and the second buffer device 3, the first limit seat 21 and the second limit seat 31 are injection molded, and weigh 5-10g; the first buffer pad 22 and the second buffer pad 32 are rubber molded, and weigh 10-15g; the first limit column 23 and the second limit column 33 are lathe-processed, and weigh 10-15g. In other words, the first buffer device 2 and the second buffer device 3 are each composed of three components, and weigh about 30g. Compared with the 490g main body 1, a better balance is achieved in cost and vibration reduction effect.

[0043] The present invention uses specific embodiments to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method and core idea of ​​the present invention. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present invention.
