DETAILED DESCRIPTION

[0023] The technical scheme of the utility model will be further described in detail below by specific embodiments, and the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0024] Embodiment 1: refer to Figures 1 to 5 A compressor stator support, the compressor housing 6 is the basic structure of the whole compressor, and the compressor housing 6 provides a mounting platform for internal components. The pump body 3 inside the housing is one of the core components of the compressor, and the pump body 3 is responsible for compressing gas. In order to ensure the stability of the pump body 3 during operation, the first stator support 1 and the second stator support 2 are specially designed above the stator 33, which are symmetrically arranged and can uniformly disperse the weight of the stator, reduce vibration, and thus improve the operating efficiency of the compressor.

[0025] The first stator support 1 is designed with a first leg 11 and a first fixing hole 12 at both ends, which allows the support to be firmly fixed to the compressor shell 6, while the first leg 11 provides an additional support point, enhancing the stability of the entire structure. The first fixing hole 12 is used to install bolts or other fasteners to ensure a tight connection between the support and the compressor shell. The second stator support 2 is designed similarly, with a second leg 21 and a second fixing hole 22 providing support and fixing functions respectively. The overall curved structure design of the two stator supports not only enhances the load-bearing capacity of the supports, but also improves their adaptability to irregular loads. This structural design allows the supports to better distribute stress when under pressure, reducing local stress concentration and prolonging the service life of the supports. The first arc edge 14 of the first stator support 1 closely fits the compressor shell 6, maximizing the contact area between the support and the shell and providing better support and stability. The gap between the first inner edge 15 and the stator 33 not only provides space for thermal expansion, but also reduces friction between the support and the stator, reducing wear and ensuring smooth rotation of the stator.

[0026] The design of the second stator support 2 also takes into account the close fit with the compressor shell 6, and the design of the second arc edge 24 helps to improve the stability of the support. The gap between the second inner edge 25 and the stator 33 also takes into account the need for thermal expansion and reduced friction. The application of this design on both supports, the design of the weight-reducing hole 13 of the first stator support 1 not only reduces the weight of the support and the overall weight of the compressor, but is particularly important in situations where lightweight design is required, such as portable or mobile compressors. The weight-reducing hole 13 also helps to improve the heat dissipation performance of the support, which is crucial for maintaining the stable operation of the compressor and prolonging its service life.

[0027] In summary, the design of this compressor stator support takes into account stability, weight reduction and heat dissipation performance, and through various components and structures, it achieves efficient and stable operation of the compressor. This design not only improves the performance of the compressor, but also reduces maintenance costs.

[0028] Example 2: Referring to Figures 1 to 5 A compressor stator support, the outer shell of the compressor, i.e. the shell 6, constitutes the framework of the entire compressor, which not only provides physical protection for the internal components of the compressor, but also serves as a mounting platform. Inside the shell, the pump body 3 is a key component of the compressor, responsible for compressing gas. In order to ensure the stability of the pump body 3 during operation, especially above the stator 33, symmetrical first stator support 1 and second stator support 2 are designed, which can evenly distribute the weight of the stator and reduce vibration, thereby improving the working efficiency of the compressor.

[0029] The first stator bracket 1 and the second stator bracket 2 are designed with great precision. The first stator bracket 1 is equipped with a first leg 11 and a first fixing hole 12 at both ends, respectively. This layout enables the bracket to be stably installed on the compressor shell 6, and the first leg 11 provides an additional support point, enhancing the stability of the overall structure. The first fixing hole 12 is used to install fasteners such as bolts, ensuring a tight connection between the bracket and the compressor shell. The second stator bracket 2 also adopts a similar design, with a second leg 21 and a second fixing hole 22 responsible for support and fixation, respectively.

[0030] Both stator brackets adopt an overall curved structural design, which not only enhances their load-bearing capacity but also improves their adaptability to non-uniform loads. This structure enables the brackets to more effectively distribute stress when under pressure, reducing stress concentration points and prolonging the service life of the brackets.

[0031] The first arc edge 14 of the first stator bracket 1 closely fits the compressor shell 6, maximizing the contact area between the bracket and the shell and providing stronger support and stability. The gap intentionally left between the first inner edge 15 of the first stator bracket 1 and the stator 33 not only provides space for thermal expansion but also reduces friction between the bracket and the stator, reducing wear and ensuring smooth rotation of the stator.

[0032] The second stator bracket 2 also considers close fitting with the compressor shell 6, with the design of the second arc edge 24 helping to enhance the stability of the bracket. The gap between the second inner edge 25 and the stator 33 also takes into account the need for thermal expansion and reduced friction, reflecting the designer's attention to the details of compressor operation.

[0033] The first weight-reducing hole 13 on the first stator bracket 1 reduces the weight of the bracket, thereby reducing the overall weight of the compressor, which is particularly important in situations requiring lightweight design, such as portable or mobile compressors. The first weight-reducing hole 13 also helps improve the heat dissipation performance of the bracket, which is crucial for maintaining stable operation and prolonging the service life of the compressor.

[0034] A notable feature of the second stator bracket 2 is the second weight-reducing hole 23 specially designed at one end of the bracket. This weight-reducing hole 23 is carefully designed on the side of the second fixing hole 22. Such a design not only helps to reduce the overall weight of the second stator bracket 2, thereby reducing the total weight of the compressor, but also improves the heat dissipation efficiency and dynamic response capability of the bracket without affecting the structural strength. This design is particularly important in applications requiring lightweight and high efficiency, such as in the design of mobile or portable compressors, where weight reduction and improved heat dissipation performance are key considerations.

[0035] The pump body 3 is designed to comprise two parts, a pump body head 31 and a pump body tail 32. In this design, the first weight reduction hole 13 and the second weight reduction hole 23 are arranged near one end of the pump body head 31. This layout helps to optimize the airflow and heat distribution inside the compressor, as the pump body head 31 is usually the hottest part of the compressor, and the arrangement of the weight reduction holes can improve the heat dissipation efficiency of this area, while reducing the weight, which is crucial for maintaining the high efficiency of the compressor and prolonging its service life.

[0036] The bottom of the compressor housing 6 is designed with several fixtures 7, above which is a bushing 6. This design provides a stable foundation, allowing the compressor to be safely installed on various platforms. The fixtures 7 not only enhance the stability of the compressor, but also help to disperse the vibrations and pressures generated during the operation of the compressor, protecting it from damage. The use of the bushing 6 further improves the durability and maintainability of the compressor, as it reduces direct contact between the fixtures 7 and the compressor housing 6, reducing wear and tear, while also facilitating the disassembly and maintenance of the compressor. This design is particularly useful in industrial environments that require frequent movement or regular maintenance, as it improves the reliability and maintenance convenience of the compressor.

[0037] Example 3: Reference Figures 1 to 5 The compressor stator support, the external protective structure of the compressor, that is, the housing 6, is the frame of the entire machine, which not only protects the various components inside the compressor, but also serves as the mounting base for these components. Inside the housing 6, the pump body 3 serves as the core component of the compressor, responsible for the function of gas compression. To ensure the stability of the pump body 3 during operation, a pair of first stator supports 1 and second stator supports 2 are specially designed to be located above the stator 33 and evenly bear the weight of the stator through a symmetrical layout, reducing vibration and improving the working efficiency of the compressor.

[0038] The first stator support 1 and the second stator support 2 are designed very precisely. The first stator support 1 is equipped with a first leg 11 and a first fixing hole 12 at both ends, which allows the support to be stably installed on the compressor housing 6. The first leg 11 serves as an additional support point, enhancing the stability of the overall structure. The first fixing hole 12 is used to install fasteners such as bolts to ensure the tight connection between the support and the compressor housing. The second stator support 2 also adopts a similar design, with a second leg 21 and a second fixing hole 22 serving as support and fixation respectively.

[0039] The two stator brackets adopt an overall bending structure design, which not only enhances the carrying capacity of the brackets, but also improves their adaptability to uneven loads. This design enables the brackets to more effectively disperse stress when under pressure, reducing stress concentration points and thus prolonging the service life of the brackets.

[0040] The first arc edge 14 of the first stator bracket 1 closely fits the compressor housing 6, maximizing the contact area between the bracket and the housing and providing stronger support and stability. The gap intentionally left between the first inner edge 15 of the first stator bracket 1 and the stator 33 allows for thermal expansion and reduces friction between the bracket and the stator, reducing wear and ensuring smooth rotation of the stator.

[0041] The second stator bracket 2 also takes into account the close fit with the compressor housing 6, with the design of its second arc edge 24 helping to enhance the stability of the bracket. The gap between the second inner edge 25 and the stator 33 also takes into account the need for thermal expansion and reduced friction, reflecting the designer's attention to the details of compressor operation.

[0042] The first weight-reducing hole 13 on the first stator bracket 1 is a clever design that reduces the weight of the bracket, thereby reducing the overall weight of the compressor, which is particularly important in situations where lightweight design is required, such as portable or mobile compressors. The first weight-reducing hole 13 also helps improve the heat dissipation performance of the bracket, which is crucial for maintaining stable operation and extending the service life of the compressor.

[0043] In the design of the compressor stator bracket, the optimization of the second stator bracket 2 is crucial. In particular, the second stator bracket 2 is designed with a second weight-reducing hole 23 at one end, which is cleverly arranged next to the second fixing hole 22. Such design details not only reduce the weight of the second stator bracket 2, but also have a positive impact on the overall weight control of the compressor. More importantly, this weight-reducing design does not sacrifice the structural strength of the bracket, but rather improves the heat dissipation efficiency and response capability to dynamic loads through the arrangement of the weight-reducing hole. This is particularly important for compressors that pursue lightweight and high efficiency, especially in the design of mobile or portable compressors, where weight reduction and heat dissipation performance improvement become key factors that must be considered in the design.

[0044] In the design of the pump body 3, the pump body is divided into two parts, the pump body head 31 and the pump body tail 32, which helps to better manage and optimize the space inside the compressor. The first weight reduction hole 13 and the second weight reduction hole 23 are carefully arranged near the end of the pump body head 31, and such a layout is crucial for the distribution of air flow and heat. Since the pump body head 31 is usually the part that generates the most heat, the arrangement of the weight reduction holes not only improves the heat dissipation efficiency of this area, but also helps to reduce the weight, which is of great significance to maintaining the high efficiency of the compressor and prolonging its service life.

[0045] The bottom of the compressor housing 6 is designed with several fixing parts 7, which provide a solid mounting base for the compressor, ensuring that the compressor can be stably installed on various platforms. The presence of the fixing parts 7 not only enhances the stability of the compressor, but also helps to disperse the vibrations and pressures generated during the operation of the compressor, thereby protecting the compressor from damage. The bushing 6 is arranged above the fixing parts 7, further improving the durability and maintainability of the compressor. The bushing 6 reduces direct contact between the fixing parts 7 and the compressor housing 6, reducing wear and tear, while also simplifying the disassembly and maintenance of the compressor. This design is particularly important in industrial environments that require frequent movement or regular maintenance, as it improves the reliability of the compressor and the convenience of maintenance.

[0046] In the design of the compressor stator support, the bushing 6 serves to fix the support spring 5, while the support spring 5 fixes the first leg 11 of the first stator support 1 and the second leg 21 of the second stator support 2, respectively. This design allows the stator support to be elastically connected to the compressor housing 6 through the support spring 5, thereby absorbing vibrations during the operation of the compressor, reducing noise, and protecting the stator support from damage caused by mechanical vibrations. The use of the support spring 5 also helps to reduce the impact on the stator support during the start and stop of the compressor, prolonging its service life.

[0047] In the design of the compressor stator support, the first fixing hole 12 and the second fixing hole 22 are positioned with bolts, and the sizes of the two fixing holes are the same. This standardized design helps to simplify the production process, as the same bolts and tools can be used to fix the first stator support 1 and the second stator support 2, thereby improving assembly efficiency and maintenance convenience. At the same time, the same size of the fixing holes also means that the same fasteners can be used, reducing the types and inventory of spare parts, and reducing maintenance costs.

[0048] The hole diameters of the first and second lightening holes 13 and 23 in the compressor stator support are slightly larger than those of the first and second fixing holes 12 and 22. This design allows the lightening holes to reduce the weight of the support while maintaining sufficient structural strength. The slightly larger diameter of the lightening holes can provide better heat dissipation channels, helping to quickly dissipate heat, especially during high-load operation of the compressor. This design can effectively prevent local overheating and protect the stator support from thermal damage. At the same time, this design also helps to improve the processing efficiency of the material, as larger holes are easier to achieve through mechanical processing, reducing complexity and cost in the manufacturing process.

[0049] In summary, these design features of the compressor stator support work together to not only improve the stability and durability of the compressor, but also optimize its heat dissipation performance and maintenance convenience, allowing the compressor to reliably operate under various working conditions while reducing maintenance costs and improving production efficiency.

[0050] The present application is not limited to the details of the above exemplary embodiments, but can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application.
