Description

Technical Field

[0001] This application relates to the field of compressor vibration reduction technology, and more particularly to a compressor assembly and an air conditioner. Background Technology

[0002] Marine chillers, as specialized refrigeration and air conditioning equipment for ships, must adapt to the harsh, turbulent, and space-constrained operating conditions at sea, placing high demands on equipment reliability, vibration resistance, and structural compactness. The compressor (especially the scroll compressor) is the primary source of vibration in the chiller. Because marine chillers commonly employ variable frequency compressors to adapt to varying operating conditions, the compressor's operating frequency dynamically adjusts with cooling demand, resulting in changes in the excitation frequency.

[0003] This results in significant differences in the vibration characteristics of ships under different navigation conditions: for example, surface operation corresponds to a high-frequency vibration environment, while underwater operation corresponds to a low-frequency vibration environment. When the excitation frequency coincides with the natural frequency of the chiller unit's base components, pipelines, or the compressor itself, it can easily trigger structural resonance, causing abnormal wear of the equipment, increased noise levels, and consequently affecting the overall operational stability and shortening its service life. Summary of the Invention

[0004] This application provides a compressor assembly and an air conditioner, which aims to solve the problem of resonance that occurs during the inverter operation of the compressor.

[0005] This application provides a compressor assembly, including a compressor, a base assembly, and a vibration absorber. The compressor and the base assembly are mounted and connected. The vibration absorber includes an elastic bracket and a vibration-absorbing element. The elastic bracket is connected to the base assembly, and the vibration-absorbing element is connected to the elastic bracket. The vibration-absorbing element is configured as a mass-adjustable structure.

[0008] In some embodiments, a plurality of first positioning holes are provided on one end face of the mass block, the first positioning holes being used for detachably connecting the first counterweight and the second counterweight.

[0009] In some embodiments, along the first direction, the mass block has a second positioning hole on the outside of at least part of the first positioning hole, the second positioning hole being used at least to accommodate the first counterweight.

[0010] In some embodiments, the first counterweight is provided with a third positioning hole for detachably connecting the second counterweight.

[0011] In some embodiments, the compressor, the elastic support, and the mass block are distributed along a first direction, which is the vertical direction, and the first positioning hole is located on the lower end face of the mass block.

[0012] In some embodiments, a plurality of first positioning holes are evenly distributed around the center line of the mass block.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments.

[0025] Please see Figures 1 to 11 This application provides a compressor assembly and an air conditioner, which aims to solve the problem of resonance that occurs during the inverter operation of the compressor.

[0026] like Figure 1 and Figure 2As shown, the compressor 100 assembly includes a compressor 100, a base assembly 200, and a vibration absorber 300. The compressor 100 is mounted and connected to the base assembly 200. The vibration absorber 300 includes an elastic bracket 310 and a vibration absorber 320. The elastic bracket 310 is connected to the base assembly 200, and the vibration absorber 320 is connected to the elastic bracket 310. The vibration absorber 320 is configured as a mass-adjustable structure.

[0027] The base assembly 200 is used to support and position the compressor 100. The base assembly 200 can be a plate-like structure or a support structure. Figure 1 As shown, the base assembly 200 may include a base plate 210 and multiple support feet 220. The base plate 210 has base holes corresponding to the multiple support feet of the compressor 100, so as to connect the support feet to the base plate 210 by bolts. The support feet 220 are provided between the support feet and the base plate 210 for adjusting the installation height of the compressor 100, and the support feet 220 can also be set as a buffer structure to buffer and absorb the vibration during the operation of the compressor 100.

[0028] The vibration absorber 300 is a device used to absorb or reduce system vibration by generating an anti-vibration with the main system to counteract or weaken the vibration energy of the main system. The elastic support 310 is a component of the vibration absorber 300; its function is to provide elastic support, allowing the vibration absorber 320 to vibrate within a certain range and to transmit vibration energy. The adjustable mass structure refers to a configuration where the mass of the vibration absorber 320 can be adjusted according to actual needs. By changing the mass of the vibration absorber 320, the natural frequency of the vibration absorber 300 can be changed, thereby enabling it to adapt to the vibration suppression requirements of the compressor 100 at different frequencies.

[0029] For example, the mass can be adjusted by adding or removing additional mass blocks 321 to the vibration absorber 320, or by changing the density of the filling material inside the vibration absorber 320. By adjusting the mass of the vibration absorber 320, the natural frequency of the vibration absorber 300 can be changed, enabling it to avoid the excitation frequency generated by the compressor 100 under different operating conditions, thereby optimizing the vibration reduction effect.

[0030] Thus, by configuring the vibration absorber 320 as a mass-adjustable structure, the natural frequency of the vibration absorber 300 can be adjusted according to the operating frequency of the compressor 100 under different operating conditions. This effectively avoids resonance problems caused by the excitation frequency coinciding with the structure's natural frequency, making it particularly suitable for the variable frequency operation requirements of marine scroll chillers under high-frequency conditions on the water surface and low-frequency conditions underwater. This helps reduce equipment wear and operating noise, and improves the operational stability and service life of the chiller unit.

[0031] In some embodiments, such as Figure 3 and Figure 4As shown, the vibration damping component 320 includes a mass block 321 and several counterweight blocks 322. The mass block 321 is connected to the elastic support 310, and the counterweight blocks 322 are detachably connected to the mass block 321.

[0032] The mass block 321 is the main mass-bearing component of the vibration absorber 320. It is connected to the elastic support 310 and together they form the core vibration unit of the vibration absorption system. The mass block 321 can be made of metal or alloy to provide the required inertial mass. Its shape and size can be designed according to the actual application scenario and space constraints, for example, it can be cylindrical, square, or a structure with specific geometric features.

[0033] Several counterweights 322 are auxiliary mass units used to achieve fine adjustment of the mass of the vibration absorber 320. The mass of these counterweights 322 is usually smaller than that of the mass block 321, and they can be added, removed, or replaced as needed. The material of the counterweights 322 can be the same as or different from that of the mass block 321, and their shape can be designed in various forms that facilitate installation and disassembly, such as cylinders, rings, or plates.

[0034] A detachable connection refers to a connection between the counterweight 322 and the mass block 321 that allows for repeated installation and removal without damaging the components. This connection method aims to provide convenient mass adjustment operations to accommodate different tuning needs. Common detachable connection methods include, but are not limited to, threaded connections, snap-fit ​​connections, pin connections, magnetic connections, or connections achieved through fasteners (such as bolts and nuts). Selecting a suitable connection method requires comprehensive consideration of connection strength, operational efficiency, and reliability against vibration and loosening.

[0035] Thus, mass block 321 serves as the main mass of the vibration absorber 320, while counterweight block 322 acts as an auxiliary mass. By increasing or decreasing the number of counterweight blocks 322 or replacing them with counterweight blocks of different masses, the total mass of the vibration absorber 320 can be easily and quickly changed. This modular mass adjustment method allows the vibration absorption system to be precisely tuned according to the vibration frequency generated by the compressor 100 under different operating conditions, thereby effectively adjusting the natural frequency of the vibration absorber 320 to match the main vibration frequency of the compressor 100, significantly improving the vibration absorption effect. In addition, the detachable connection design ensures the convenience and reliability of the mass adjustment process, eliminating the need to replace the entire vibration absorber 300, reducing maintenance costs and operational difficulty, and improving the adaptability and versatility of the compressor 100 components. Among them, such as Figure 3 and Figure 4As shown, the counterweight 322 includes a first counterweight 3221 and a second counterweight 3222, wherein the mass of the first counterweight 3221 is greater than the mass of the second counterweight 3222. The first counterweight 3221 is detachably connected to the mass block 321, and the second counterweight 3222 is detachably connected to at least one of the mass block 321 and the first counterweight 3221.

[0036] The counterweight 322 is a component used to adjust the overall mass of the vibration absorber 320. By introducing different types of counterweights 322, namely the first counterweight 3221 and the second counterweight 3222, more options and combinations can be provided for mass adjustment, thereby improving the flexibility and efficiency of mass adjustment.

[0037] The first counterweight 3221, due to its larger mass, is mainly used for large-range mass adjustments to quickly reach the desired approximate mass value. The second counterweight 3222, due to its smaller mass, can be used for small-range fine-tuning to precisely switch the natural frequency of the vibration absorber 300, thereby achieving a better vibration reduction effect.

[0038] For example, the mass of the first counterweight 3221 can be several times the mass of the second counterweight 3222, such as 2 times, 5 times or 10 times. The specific value can be designed according to the actual application requirements and adjustment accuracy requirements.

[0039] The detachable connection method ensures that the first counterweight 3221 and the second counterweight 3222 can be easily installed or removed as needed. This connection method can take various forms, such as threaded connection, snap-fit ​​connection, pin connection, or magnetic connection, to ensure reliability and ease of operation. By selectively installing different numbers and types of the first counterweight 3221 and the second counterweight 3222, the mass of the vibration-absorbing component 320 can be flexibly configured.

[0040] By using differentiated counterweights 322, when adjusting the mass of the vibration absorber 320, a coarse and wide-range mass adjustment can be made first using the larger first counterweight 3221 to quickly approach the target mass value. Subsequently, a finer adjustment is made using the smaller second counterweight 3222 to achieve precise control over the mass of the vibration absorber 320. This not only significantly improves the efficiency and accuracy of mass adjustment and reduces the time spent on repeated trial and error, but also effectively reduces the total number of counterweights 322 required to achieve the same adjustment range, thereby simplifying operation and reducing maintenance costs. Therefore, this solution can more effectively match the vibration characteristics of the compressor 100 under different operating conditions, optimize the vibration reduction effect, and improve the overall operational stability of the compressor 100 components.

[0041] For example, such as Figure 4 , Figure 5and Figure 8 As shown, one end face of the mass block 321 is provided with a plurality of first positioning holes 3211, which are used to detachably connect the first counterweight 3221 and the second counterweight 3222.

[0042] The first positioning hole 3211 can be configured as a threaded hole, and the counterweight 322 is correspondingly provided with a threaded post or bolt, so as to achieve a fastening connection between the two by screwing in, thereby avoiding additional vibration and noise caused by additional shaking.

[0043] Alternatively, the first positioning hole 3211 can be configured as a snap-fit ​​hole, with a corresponding snap-fit ​​structure on the counterweight 322, allowing for quick engagement and disengagement by pressing or rotating. Furthermore, a plug-in connection can be used, where the first positioning hole 3211 is a smooth hole, and the counterweight 322 has a pin or post for insertion and securing with additional fasteners (such as pins, bolts, or spring pins). These detachable connection methods ensure that the counterweight 322 can be easily replaced or adjusted when needed, while also guaranteeing the stability of the connection and preventing loosening or detachment due to vibration during compressor 100 operation.

[0044] In some embodiments, such as Figure 4 , Figure 5 and Figure 8 As shown, along the first direction Z, the mass block 321 has a second positioning hole 3212 on the outside of at least part of the first positioning hole 3211. The second positioning hole 3212 is at least used to insert and accommodate the first counterweight 3221.

[0045] For example, on one end face of the mass block 321 along the first direction Z, a second positioning hole 3212 is provided on the outside of part or all of the first positioning hole 3211. The second positioning hole 3212 is mainly used to insert and accommodate the first counterweight 3221. For example, the second positioning hole 3212 can be a circular hole with a large diameter, and the first positioning hole 3211 is a threaded hole structure, that is, both are circular hole structures, so that after the first counterweight 3221 is screwed into the first positioning hole 3211, its main body is at least partially inserted into the second positioning hole 3212, avoiding exposure and additional occupation of vertical (up and down) space in the first direction Z.

[0046] Or, such as Figure 4 and Figure 5As shown, a third positioning hole 3223 can also be provided in the first counterweight 3221 for detachably connecting the second counterweight 3222. The end of the first counterweight 3221 is used to connect the third positioning hole 3223, which is located on opposite sides of the first counterweight 3221 along the first direction Z. In this case, the second counterweight 3222 can be installed at the end of the first counterweight 3221 as needed to adjust and increase the overall mass of the vibration absorber 320.

[0047] At this point, as needed, a separate first positioning hole 3211 can be opened on the lower end face of the mass block 321 to facilitate the installation of the second counterweight 3222 at different positions.

[0048] Alternatively, instead of having a separate first positioning hole 3211 on the lower end face of the mass block 321, a second positioning hole 3212 can be provided on the outer side of the first positioning hole 3211 on the lower end face of the mass block 321. In this case, the cross-sectional shape of the second counterweight 3222 is the same as that of the first counterweight 3221, but the height of the second counterweight 3222 is smaller than that of the first counterweight 3221. This allows the second counterweight 3222 to be inserted into the second positioning hole 3212 and detachably connected to the first positioning hole 3211.

[0049] For example, the first counterweight 3221 and the second counterweight 3222 have the same outer diameter. The first counterweight 3221 and its main body, and the main body of the second counterweight 3222, can be inserted into and adapted to the second positioning hole 3212. The upper connecting ends of both counterweights 322 are used to adapt and connect to the first positioning hole 3211 and the third positioning hole 3223.

[0050] It should be noted that, as Figure 1 and Figure 2 As shown, the compressor 100, the elastic support 310, and the mass block 321 are arranged sequentially along the first direction Z, where the first direction Z is the vertical direction (e.g., the vertical direction). Furthermore, as... Figure 3 As shown, the first positioning hole 3211 is located on the lower end face of the mass block 321. This makes the entire compressor 100 assembly form a compact and stable mounting structure in the vertical direction. This layout not only optimizes space utilization but also facilitates the installation and removal of the counterweight block 322 from below, improving operational convenience.

[0051] It should be noted that in this embodiment, the mass block 321 is a regular structure with its center line overlapping the center of gravity, avoiding additional vibration caused by center of gravity shift. Multiple first positioning holes 3211 are evenly distributed around the center line of the mass block 321, so that they are symmetrically distributed when installing the first counterweight 3221 or the second counterweight 3222. This ensures that the overall mass distribution of the mass block 321 remains balanced after the counterweight 322 is installed, effectively avoiding additional vibration caused by off-center loading, thereby improving vibration absorption and the operational stability of the component.

[0052] In some embodiments, such as Figure 8 As shown, the end face of the mass block 321 with the first positioning hole 3221 and the insertion blind hole 3213 can be a rectangular, square, or circular face. Taking the end face as a square face as an example, two second positioning holes 3222 are provided at intervals along each diagonal. The four positioning holes 3222 are located at the same position from the intersection of the two diagonals, and each second positioning hole 3222 also contains a first positioning hole 3221. A first positioning hole 3221 is provided at the midpoint of the line (non-diagonal) connecting two adjacent second positioning holes 3222 to form the connection point of the four first positioning holes 3221.

[0053] In some embodiments, such as Figure 5 and Figure 9 As shown, the mass block 321 is provided with a blind insertion hole 3213 and a mounting hole 3214 communicating with the blind insertion hole 3213 along the first direction Z. Combined with... Figure 4 and Figure 8 The vibration damping component 320 also includes a connecting block 323, which is adapted to be inserted into the blind insertion hole 3213. The size of the mounting hole 3214 is smaller than the size of the connecting block 323, and the inner diameter of the mounting hole 3214 is smaller than the inner diameter of the blind insertion hole 3213. The connector is connected to the elastic bracket 310. Alternatively, the connecting block 323 may not be required, allowing the elastic bracket 310 to be connected to the mounting hole 3214. The elastic bracket 310 may be detachably connected to the mounting hole 3214 or the connecting block 323.

[0054] Thus, the connecting block 323 can be inserted into the blind insertion hole 3213. Due to the limiting effect of the upper mounting hole 3214, the connecting block 323 can be prevented from detaching from the blind insertion hole 3213 from the top. At this time, the elastic bracket 310 and the connecting block 323 can be connected by bolts passing through the mounting hole 3214 for a detachable connection between the two. Alternatively, rivets can be used for the connection and installation between the two. This allows the connecting block 323 and the mass block 321 to function as a whole, and the elastic bracket 310 provides damping vibration in the vertical direction (i.e., the first direction Z), thereby absorbing the vibration energy during the operation of the compressor 100 and preventing the compressor assembly from generating larger or more intense vibrations and noise.

[0055] In some embodiments, such as Figure 9 As shown, the connecting block 323 includes a main body portion 3231 and a connecting portion 3232 connected in sequence. The connecting portion 3232 can be disposed at one end of the main body portion 3231, or it can be disposed at both ends of the main body portion 3231. The outer diameter of the main body portion 3231 is smaller than the inner diameter of the insertion blind hole 3213, and the outer diameter of the connecting portion 3232 is smaller than the inner diameter of the mounting hole 3214.

[0056] Alternatively, the blind insertion hole 3213 and the mounting hole 3214 may be polygonal holes with triangular, quadrilateral or pentagonal cross sections, while the main body 3231 and the connecting part 3232 may be polygonal prism structures that are compatible with them for insertion. This is not limited.

[0057] At this time, as Figure 9 As shown, at least one connecting hole 3233 is provided at the connecting portion 3232 to connect the connecting block 323 to the elastic bracket 310 via bolts or rivets. The connecting hole 3233 can be a blind hole or a through hole. In this case, along the first direction Z, the height of the connecting portion 3232 is greater than the height of the mounting hole 3214, allowing the mass block 321 to slide vertically relative to the connecting block 323.

[0058] It should be noted that if the mass component 321 in the vibration absorber 320 cannot be stably connected to the elastic support 310, it will not only affect the calculation of the natural frequency of the vibration absorber 300, but also cause additional vibration to the entire system compared to the mass component 321 swaying up and down or left and right compared to the elastic support 310.

[0059] Thus, during the connection and installation of the elastic bracket 310 and the connecting block 323, since the connecting portion 3232 at the upper end of the connecting block 323 contacts the elastic bracket 310 under the fixation of bolts or rivets, an annular gasket (sleeved on the outside of the connecting portion 3232) or a compression filler can be placed between the mass block 321 and the elastic bracket 310 to prevent the mass block 321 from swaying up and down or left and right relative to the connecting block 323 and the elastic bracket 310. This helps to increase the effective contact area and connection stability between the mass block 321 and the elastic bracket 310, thereby improving the stability of the vibration absorber 300 during the vibration energy absorption process.

[0060] Alternatively, along the first direction Z, the height of the connecting part 3232 is less than or equal to the height of the mounting hole 3214, so that after the mass block 321 is connected and installed through the connecting block 323, the mass block 321 can directly contact the elastic bracket 310 and be pressed and fixed below the elastic bracket 310 under the action of bolts or rivets, so as to avoid the mass block 321 from swaying up and down or left and right relative to the connecting block 323 and the elastic bracket 310, thereby improving the stability of the vibration absorber 300 during the vibration energy absorption process.

[0061] For example, such as Figure 2 and Figure 3 As shown, the elastic bracket 310 includes at least three claws 313, which are connected to the base assembly 200. The vibration damping member 320 is detachably connected to the center of gravity of the elastic bracket 310 to facilitate the installation, removal, maintenance or replacement of the vibration damping member 320.

[0062] As a key component of the vibration absorber 300, the elastic bracket 310's elastic properties enable the vibration-absorbing element 320 to vibrate relative to the base assembly 200, thereby dissipating vibration energy. To ensure a stable and reliable connection between the elastic bracket 310 and the base assembly 200, this application designs at least three latches 313. These latches 313 can engage or fasten with corresponding structures (such as slots, holes, or protrusions) on the base assembly 200, forming a secure and non-loose connection. The configuration of at least three latches 313 provides a stable three-point or multi-point support, effectively preventing the elastic bracket 310 from swaying or displacing during vibration, thus ensuring the stability of the entire vibration absorption system.

[0063] As the main mass component, the vibration absorber 320 functions to generate reverse vibration to counteract the vibration generated by the compressor 100. To optimize the vibration absorption effect, this application detachably connects the vibration absorber 320 to the center of gravity of the elastic support 310, or offsets it by a distance less than or equal to 2mm, which can minimize the additional torque or eccentric load caused by the connection position deviating from the center of gravity. This connection method ensures that the vibration absorber 320 mainly undergoes translational motion during vibration, avoiding unnecessary tilting, torsion, or swaying, thereby enabling the vibration absorber 320 to absorb and transfer vibration energy more purely and efficiently.

[0064] The arrangement of at least three locking claws 313 ensures high stability and reliability in the connection between the elastic support 310 and the base assembly 200, effectively preventing loosening or displacement due to vibration during compressor 100 operation. Simultaneously, the detachable connection of the vibration absorber 320 to the center of gravity of the elastic support 310 significantly optimizes the vibration mode of the absorber 320, enabling it to absorb and dissipate vibration energy more efficiently, reducing additional vibration or structural fatigue caused by eccentric loads. This center-of-gravity connection method, combined with the adjustable mass of the vibration absorber 320, allows the entire vibration absorption system to be precisely adjusted according to actual operating conditions, thereby significantly improving the overall vibration reduction effect and operational reliability of the compressor 100 assembly while ensuring system stability.

[0065] In some embodiments, such as Figure 3 As shown, the elastic support 310 includes a positioning member 311 and at least two elastic frames 312. The positioning member 311 is connected to the vibration-absorbing member 320 (mass block 321). One end of the elastic frame 312 is provided with at least two spaced claws 313, and the other end of the elastic frame 312 is detachably connected to the positioning member 311 so that the multiple claws 313 are spaced around the positioning member 311.

[0066] The positioning component 311 can be designed as a ring, disc, groove, or structure with a specific geometry, and may have features such as threaded holes, slots, or bosses to connect and fix it to the mass block 321 and the elastic frame 312. The positioning component 311 ensures the accurate installation position of the mass block 321 on the elastic support 310, thereby guaranteeing the overall balance and vibration reduction effect of the vibration absorber 300. The connection method between the positioning component 311 and the mass block 321 can be varied, such as by bolts, screws, riveting, welding, or snap-fitting. This ensures that the vibration of the mass block 321 can be effectively transmitted to the base assembly 200 and the compressor 100 via the elastic frame 312, thereby absorbing and dissipating the vibration energy during the operation of the compressor 100. At least two elastic frames are provided to offer multi-point support, enhance the overall stability of the vibration absorber 300, and ensure that vibration energy is evenly distributed and absorbed. One end of the elastic frame 312 is provided with at least two spaced-apart claws 313, which serve as intermediaries for connecting the elastic frame 312 to the base assembly 200. These claws 313 can be designed as hooks, U-shaped clamps, L-shaped legs, or lugs with bolt holes, etc., to securely connect with corresponding structures on the base assembly 200. By spaced-aparting the claws 313 at one end of the elastic frame, the contact area between the elastic support 310 and the base assembly 200 can be expanded, improving the stability of the connection and helping to evenly transfer vibration loads to the base assembly 200.

[0067] The other end of the flexible bracket 312 is detachably connected to the positioning element 311. This detachable connection, for example, is achieved through bolts, pins, clips, or plugs, facilitating the modular assembly of the flexible bracket 310. This connection method allows the flexible bracket 312 to be installed, disassembled, or replaced independently of the positioning element 311, greatly simplifying the production assembly process, reducing maintenance costs, and allowing the number or type of flexible brackets to be adjusted according to actual needs.

[0068] By setting multiple claws 313 spaced apart and evenly distributed around the positioning member 311, and connecting the other end of the elastic frame 312 to the central positioning member 311, the claws 313 of the elastic frame 312 are spatially spaced or evenly distributed around the positioning member 311, ensuring that the supporting force borne by the mass block 321 is balanced and symmetrical. This uniform distribution helps prevent the vibration absorber 300 from tilting or being unbalanced during operation. It ensures that the supporting force of the vibration absorber 300 on the compressor 100 is evenly distributed, effectively avoiding unbalanced loads and vibrations, thereby significantly improving the vibration reduction efficiency and stability of the vibration absorber 300 and extending the service life of the compressor 100 components.

[0069] Overall, the design of the vibration absorber 300 should be based on the design specifications and principles of vibration absorbers, comprehensively considering the related effects of damping, mass, and stiffness. The optimal design of the vibration absorber 300 can be simply achieved by applying the optimal harmony condition and optimal damping. The mechanical model is shown below. Figure 11 .

[0070] Establish a system of differential equations using Newton's method: ; Where f is the excitation force of the main system (i.e., compressor 100 and base assembly 200). m, k, and c are the mass, stiffness, and damping parameters of the vibration absorber 300, respectively. M and K are the mass and stiffness parameters of the main system structure, respectively. x1 and x2 are the displacement parameters of the main system and the vibration absorber 300, respectively.

[0071] Solving according to the optimal homology condition, at this point: ; Where γ is the ratio of the natural angular frequency of the vibration absorber 300 to that of the main system. M is the mass ratio of the vibration absorber 300 to that of the main system, i.e., m / M. ω2 is the natural angular frequency of the vibration absorber 300, i.e. The unit is (rad / s). ω1 is the natural angular frequency of the main system, i.e. The unit is (rad / s).

[0072] When the mass ratio is μ, the design formulas for the three key parameters constituting the vibration absorber 300 are as follows: The quality of the dynamic vibration absorber ; Stiffness of the elastic element of the dynamic vibration absorber (N / m) ; Damping coefficient of dynamic vibration absorber (N·s / m). ; When the vibration absorber 300 moves with the main system, the vibration of the main system is suppressed, but the vibration absorber 300 itself vibrates strongly, which to some extent transfers the vibration energy of the main system to the vibration absorber 300 and dissipates the energy through its own damping.

[0073] According to the above formula, we can obtain: The vibration absorber 300 is designed with a natural frequency of, .

[0074] Based on the design principle of the vibration absorber 300 described above, and considering the two main operating conditions of marine vortex chillers—surface (high frequency) and underwater (low frequency)—a variable fixed-frequency (i.e., mass) vibration absorber 300 mounting assembly is designed. For example, nuts are spot-welded onto the elastic bracket 310, and the mass block 321 in the vibration absorber 300 is connected to the elastic bracket 310 using mounting bolts. The mounting bolts on the elastic bracket 310 are used for fixation, and finally, the entire vibration absorber 300 is fixed to the bottom of the compressor.

[0075] To adapt to vibration reduction under various operating conditions of the compressor, the vibration absorber 300 consists of multiple counterweights 322 to change its own mass and thus its natural frequency. This is mainly divided into the following three types: 1. When compressor 100 operates in a water surface condition, its operating frequency is relatively high. Assuming a rated operating frequency of 56Hz, design the mass of the vibration-absorbing component 320 of the vibration absorber 300 based on this target frequency. Its structure is as follows: Figure 10 As shown, its cross-sectional structure is as follows Figure 9 As shown. Therefore, in water surface conditions, the vibration absorber 300 only needs to use the mass block 321 for vibration absorption.

[0076] II. When compressor 100 operates underwater, its operating frequency is relatively low. Assuming a rated operating frequency of 36Hz, the mass of the vibration absorber 320 is designed based on this target frequency, and its structure is as follows: Figure 5 As shown, due to the decrease in operating frequency, the mass of the vibration absorber 300's mass block 321 needs to be increased, and positioning holes have been pre-designed at the bottom of the mass block 321. Therefore, at low frequencies, such as Figure 8 As shown, a first counterweight 3221 is installed at the second positioning hole 3212, so that the mass of the vibration absorber 320 is increased to absorb vibration at the characteristic frequency of the low-frequency target.

[0077] III. Due to operational requirements, the actual operating frequency of the compressor 100 may decrease by 1~2Hz from the rated operating frequency. Therefore, the characteristic target frequency requiring a lower peak value may be slightly lower. To optimize the effect of the vibration absorber 300, the mass of the vibration absorber 320 needs to be adjusted as needed. Therefore, a first positioning hole 3211 and a third positioning hole 3223 are provided at the bottom of the mass block 321 and the first counterweight 3221. Figure 7 As shown, when the mass needs to be adjusted under surface conditions, the second counterweight 3222 can be installed at the bottom of the mass block 321. Figure 6 As shown, when underwater conditions require mass correction, the second counterweight 3222 can be installed at the bottom of the first counterweight 3221 to reduce the vibration absorption frequency.
