Description

Technical Field

[0001] This utility model relates to the field of compressor technology, specifically to a pump support, support assembly and compressor. Background Technology

[0002] With the continuous development of industrial technology, compressors are being used more and more widely in refrigeration, air conditioning, chemical and other fields. Consequently, the noise problem generated by compressors during operation is becoming increasingly prominent.

[0003] Valve noise is one of the main sources of noise in compressor operation. It not only affects the overall noise level of the compressor but also the perceived noise level of the equipment using the compressor, reducing the customer experience. Valve noise is generally caused by the valve plate forcefully striking the pump support after high-pressure gas is discharged during compressor operation, as it needs to seal the exhaust port promptly. Furthermore, during compressor operation, the pump operates at high speed, requiring high-speed intake and exhaust, so the valve plate repeatedly strikes the pump support, exacerbating the valve noise.

[0004] In existing technologies, valve noise is generally reduced by decreasing the contact area between the valve plate and the pump support. However, this reduction in contact area puts a strain on the overall sealing performance of the compressor. Therefore, researching a technology that can effectively reduce compressor valve noise, improve the listening experience of equipment using the compressor, and simultaneously ensure the overall sealing performance of the compressor is of great significance for the development of compressors in refrigeration, air conditioning, and chemical industries. Utility Model Content

[0005] To address the shortcomings of the prior art, this invention provides a pump support. By using an exhaust buffer groove corresponding to the exhaust port and located on the valve plate positioning groove, the contact area with the sealing valve plate is reduced. This reduces the impact force and noise of the sealing valve plate striking the support body during sealing. Furthermore, the exhaust buffer groove can store some gas during the compressor's exhaust process, creating a rebound buffer zone between the sealing valve plate and the exhaust buffer groove during sealing, further effectively reducing the impact force and noise of the sealing valve plate on the support body. Additionally, a buffer groove partition wall protruding from the bottom of the exhaust buffer groove can divide the exhaust buffer groove into multiple exhaust buffer zones, which can be designed according to the actual operating speed of the compressor to meet the usage requirements of the compressor under different operating conditions.

[0054] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are some, but not all, of the embodiments of this utility model.

[0055] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0056] Example 1:

[0057] Please see the appendix Figure 1 , 24. The pump support 10 of this utility model embodiment includes a support body 100, a valve plate positioning groove 200 disposed on the support body 100 for limiting and installing the sealing valve plate 30, an exhaust hole 300 passing through the valve plate positioning groove 200 for compressor exhaust, an exhaust buffer groove 400 corresponding to the exhaust hole 300 and opened on the valve plate positioning groove 200, and a buffer groove partition wall 500 protruding from the bottom of the exhaust buffer groove 400 for dividing the exhaust buffer groove 400 into multiple exhaust buffer zones; wherein, the exhaust buffer groove 400 is used to store part of the gas during the compressor exhaust process to form a rebound buffer zone for the sealing valve plate 30, so as to reduce the impact force of the sealing valve plate 30 hitting the support body 100 when sealing. Furthermore, the exhaust port 300 is a round hole structure, which can effectively ensure the uniformity and stability of the compressor exhaust; preferably, the exhaust buffer groove 400 is a flat bottom or U-shaped bottom U-shaped buffer groove structure, the height of which is 30%-75% of the height of the exhaust port 300, and the width of which is 30%-75% of the diameter of the exhaust port 300.

[0058] Please refer to the appendix for further details. Figure 3 The 500mm buffer tank partition wall can be selected and designed according to actual needs. The specific design is as follows:

[0059] 1. The buffer trough partition wall 500 is an arc-shaped partition wall structure 501 coaxial with the exhaust hole 300 and surrounding the outer periphery of the exhaust hole 300, as shown in the attached figure. Figure 3 As shown in Figure 3-1, the interior of the exhaust buffer tank 400 can be divided into multiple interconnected exhaust buffer zones.

[0060] 2. The buffer tank partition wall 500 is an annular partition wall structure 502 coaxial with the exhaust hole 300 and surrounding the outer periphery of the exhaust hole 300, as shown in the attached figure. Figure 3 As shown in Figure 3-2, the interior of the exhaust buffer tank 400 can be divided into multiple non-interconnected exhaust buffer zones.

[0061] 3. The buffer trough partition wall 500 consists of multiple rectangular partition wall structures 503 connected to both sides of the exhaust buffer trough 400, as shown in the attached figure. Figure 3 As shown in Figure 3-3, the interior of the exhaust buffer groove 400 can be divided into multiple non-interconnected exhaust buffer zones, and multiple rectangular partition wall structures 503 are evenly distributed on the exhaust buffer groove 400 with the center line of the exhaust hole 300 as the center.

[0062] The aforementioned buffer tank partition walls 500 can divide the interior of the exhaust buffer tank 400 into multiple exhaust buffer zones. This not only stores some of the gas during the compressor's exhaust process, but also creates a rebound buffer zone between the sealing valve plate 30 and the exhaust buffer tank 400 when the sealing valve plate 30 is sealing. This further effectively reduces the impact force and noise of the sealing valve plate 30 on the support body 100. Moreover, it can be designed according to the actual operating speed of the compressor to meet the usage requirements of the compressor under different operating conditions.

[0063] Please see the appendix Figure 2 , 7 8. The buffer groove partition wall 500 includes a partition wall body 510 and a sealing ring limiting groove 520 opened on the top of the partition wall body 510 for limiting the sealing ring 20; at the same time, the design of the sealing ring limiting groove 520 can also promote the flow of gas between each exhaust buffer zone, so as to improve the uniformity of the buffering force applied to the sealing valve plate 30 by multiple exhaust buffer zones, so as to prevent the sealing valve plate 30 from affecting the overall sealing performance of the compressor due to uneven force.

[0064] Please see the appendix Figure 1 In some embodiments, the valve plate positioning groove 200 includes a valve plate mounting groove 210 for mounting the sealing valve plate 30, and a valve plate movement groove 220 corresponding to the exhaust hole 300 for elastically limiting the movement of the sealing valve plate 30.

[0065] The pump support 10 of this embodiment reduces the contact area with the sealing valve plate 30 by using an exhaust buffer groove 400 corresponding to the exhaust port 300 and formed on the valve plate positioning groove 200. This reduces the impact force and noise of the sealing valve plate 30 striking the support body 100 when sealing. Furthermore, the exhaust buffer groove 400 can store some gas during the compressor's exhaust process, forming a rebound buffer zone between the sealing valve plate 30 and the exhaust buffer groove 400 when the sealing valve plate 30 seals, further effectively reducing the impact force and noise of the sealing valve plate 30 on the support body 100. Additionally, the buffer groove partition wall 500 protruding from the bottom of the exhaust buffer groove 400 can divide the exhaust buffer groove 400 into multiple exhaust buffer zones, which can be designed according to the actual operating speed of the compressor to meet the usage requirements of the compressor under different operating conditions.

[0069] Please see the appendix Figure 2 , 6 The sealing ring 20 includes a sealing ring body 21 adapted to the exhaust buffer groove 400 to ensure the overall sealing performance of the compressor, and a venting groove structure 22 evenly distributed on the sealing ring body 21 to allow gas flow. Preferably, the side of the sealing ring body 21 that contacts the sealing valve plate 30 is a planar structure to effectively ensure the stability of the sealing seal between the sealing ring 20 and the sealing valve plate 30. The venting groove structure 22 is a rectangular groove structure or a fan-shaped groove structure adapted to the part of the top of the partition wall body 510 where the sealing ring limiting groove 520 is not provided. The top of the partition wall body 510 has a sealing ring limiting groove 520, and the top of the partition wall body 510 forms a sawtooth structure. When the venting groove structure 22 is installed at the part of the top of the partition wall body 510 where the sealing ring limiting groove 520 is not provided, the overall installation and limiting of the sealing ring 20 can be achieved.

[0070] Furthermore, the valve plate protection cover 40 is an arc-shaped protective cover structure with one end away from the exhaust port 300 pressing against the sealing valve plate 30 and the other end adjacent to the exhaust port 300 suspended above the exhaust port 300; it can both protect and limit the sealing valve plate 30 to prevent damage to the sealing valve plate 30, and provide space for the elastic deformation of the sealing valve plate 30 without affecting the normal operation of the sealing valve plate 30.
