Description

Technical Field

[0001] The utility model relates to the technical field of compressors, in particular to a compressor speed stabilizing device. Background Art

[0002] Compressors play a crucial role in many areas of modern industry. For example, in the chemical industry, compressors compress and transport various gases, creating the appropriate pressure conditions for chemical reactions. In the refrigeration industry, they are core components of the refrigeration cycle, transferring heat by compressing the refrigerant to achieve the cooling effect. In the oil and gas extraction sector, compressors help lift natural gas and other gases from underground wells to the surface for subsequent transportation and processing.

[0003] The compressor consists of a transmission mechanism, a body, a valve mechanism and a shaft sealing mechanism. In a rotary vane compressor, when the rotor rotates, the blades extend outward under the action of centrifugal force, fitting tightly to the inner wall of the cylinder, dividing the cylinder into multiple sector-shaped areas. As the rotor continues to rotate, these sector-shaped areas undergo the process of suction, compression and exhaust in turn. In a complete rotation cycle, the basic working unit can complete multiple such cyclic operations, thereby realizing the compression and transportation of gas.

[0004] When some compressors are in use, the speed of the rotating shaft will be unstable due to motor fluctuations and daily use, which will cause damage to the compressor. The problems caused by the unstable rotating shaft speed are multifaceted. In chemical production, it will cause the gas delivery volume to fluctuate, seriously affecting the normal progress of chemical reactions and even causing product quality to substandard; in refrigeration components, it will cause refrigeration efficiency to fluctuate greatly and temperature control to become inaccurate, which not only affects the user experience but also shortens the service life of the equipment; from an overall perspective, a compressor that is in an unstable speed state for a long time will have its internal components subjected to uneven stress, accelerating component wear and increasing the probability of equipment failure, thereby affecting the continuity of the entire production process, causing huge economic losses and production delays to the company. Therefore, a compressor speed stabilization device is proposed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figures 1 to 3 The utility model provides an embodiment: a compressor speed stabilizing device, which aims to safeguard the stable operation of the compressor and solve a series of problems caused by factors such as speed fluctuations during actual use. The device includes a shell 1. The shell 1 serves as the exterior of the entire device, and its internal space is carefully designed and laid out. The interior of the shell 1 is rotatably connected to an adjusting block 2. The rotating connection of the adjusting block 2 inside the shell 1 is very precise and smooth. This is due to the high-precision processing technology and the adaptive connecting components, so that the adjusting block 2 can rotate freely around a specific axis without any jamming or blocking, and can flexibly respond to subsequent changes in various working conditions, providing a key motion basis for the effective operation of the entire speed stabilizing mechanism. The interior of the shell 1 is fixedly connected to a motor 19.

[0032] The internal sliding connection of the adjustment block 1-2 is connected with multiple sliding columns 13. The connection structure of these sliding columns 13 and the internal of the adjustment block 1-2 is cleverly designed, which not only ensures the smoothness of sliding, but also has good matching accuracy. It can accurately and quickly change its own position according to different force conditions inside the adjustment block 1-2, playing an indispensable regulatory role in the transmission and balance of force inside the device, helping to maintain the stability of the compressor speed. The external sliding connection of multiple sliding columns 13 is connected with the adjustment block 2-16. The adjustment block 2-16, the adjustment block 2-2 and the sliding columns 13 together constitute an interrelated and synergistic adjustment system. The adjustment block 2-16 can produce relative displacement with the adjustment block 2 through the sliding connection with the sliding columns 13. This relative sliding design enables them to adaptively make corresponding adjustments when facing changes in the speed or torque of the motor 19, thereby effectively buffering and balancing the impact of the changes, and ensuring that the entire device can fully exert its stabilizing effect on the compressor.

[0033] The interior of the adjustment block 1 2 and the adjustment block 2 16 are both provided with a slide groove 2 14. The interior of the slide groove 2 14 has been finely polished and processed, so that the sliding column 13 can strictly follow the predetermined direction and route when sliding therein, and there will be no adverse conditions such as deflection and shaking, ensuring the accuracy and reliability of the adjustment action, and providing a strong guarantee for the stable operation of the entire speed stabilization adjustment mechanism. The interior of the slide groove 2 14 is fixedly connected with a buffer block 15. The buffer block 15 is made of high-quality rubber material with high elasticity, wear resistance and good buffering performance. When the sliding column 13 slides in the slide groove 2 14 and contacts it, the buffer block 15 can effectively absorb the impact force transmitted by the sliding column 13 by virtue of its excellent elastic properties, and convert the impact force into its own elastic potential energy for storage, thereby avoiding the impact force directly impacting other key components of the device, thereby playing an important role in protecting the motor 19, compressor and various connecting components at critical moments, extending their service life and reducing the probability of failure caused by external force impact.

[0034] The top of the adjustment block 2 is fixedly connected with a counterweight block 3. The weight of the counterweight block 3 has been rigorously calculated and designed, and its existence has a key influence on the center of gravity distribution of the entire device. By reasonably increasing the weight on the top, the overall center of gravity of the device is more stable during operation, especially when dealing with vibrations, unbalanced forces, etc. generated during the operation of the compressor, the counterweight block 3 can use its own gravity to assist the device to quickly return to a stable state, effectively reduce shaking, ensure the stable operation of the compressor, and thereby improve its work efficiency and reliability. The outside of the counterweight block 3 is provided with a disassembly and assembly component for disassembly. The motor 19 serves as the power "heart" of the entire compressor speed stabilization device and has high efficiency and stable performance characteristics. It can output stable and continuous power, providing reliable driving force for the operation of the compressor and the movement of related components in the entire device, ensuring that each component can work together in a preset manner to achieve the purpose of regulating the compressor speed. Its stable power output is crucial to maintaining the normal operation of the entire component.

[0035] The bottom end of the adjusting block 2 16 is fixedly connected with a counterweight block 2 17, and the counterweight block 2 17 echoes with the counterweight block 1 3. The two work together to further optimize the overall center of gravity layout of the device, so that the device can always maintain a relatively stable state under different working conditions, whether it is placed horizontally or subjected to external force interference at a certain angle, avoiding a series of operating problems caused by unstable center of gravity, creating a stable working environment for the compressor, and ensuring its stable and efficient operation. The bottom end of the adjusting block 12 is rotatably connected to the top of the adjusting block 2 16, and the top of the adjusting block 2 is fixedly connected with a connecting column 4. The connecting column 4 serves as a "bridge" connecting the motor 19 and other key components. It has sufficient strength and rigidity. It can stably and reliably transmit the power generated by the motor 19 to the subsequent compression block 18. During the power transmission process, there will be no deformation, breakage, etc. caused by its own insufficient strength, ensuring the continuity and accuracy of power transmission, ensuring that the entire device can operate normally, and play the role of stabilizing the compressor speed.

[0036] The top of the connecting column 4 is fixedly connected to a compression block 18. Based on its unique structural design, the compression block 18 will effectively compress the gas and other media inside the compressor after receiving the power transmitted by the motor 19. In this process, through cooperation with other components in the device, the impact of factors such as speed fluctuations on the compression work can be minimized, ensuring the compression efficiency and quality of the compressor, achieving stable compression function, and meeting the needs of actual production applications. The outside of the shell 1 is fixedly connected to a coolant tank 21, which stores a sufficient amount of coolant. When the device runs for a long time and key components such as the motor 19 generate heat due to continuous work, the coolant can continuously take away the heat through the heat dissipation components such as the circulating pipeline connected to it, maintain the components working within an appropriate temperature range, prevent performance degradation, component damage and other problems due to overheating, ensure that the device can operate continuously and stably, and extend the overall service life of the device. Especially for those components that are more sensitive to temperature, the presence of the coolant tank 21 is even more indispensable.

[0037] Reference Figure 1 、 Figure 4 and Figure 5The disassembly and assembly components include two rotating blocks 5, the rear ends of the two rotating blocks 5 are rotatably connected to the front end of the counterweight block 3, and the structural design of the rotating block 5 itself ensures the flexibility and stability of its rotation. The connection part between the rotating block 5 and the counterweight block 3 has been specially reinforced, so that when the rotating block 5 rotates around the connection point, it can smoothly adjust the angle without loosening or detaching, which provides a reliable basic guarantee for subsequent disassembly and assembly operations. The operator can easily operate the rotating block 5 to perform corresponding actions to meet the needs of different usage scenarios. One of the rotating blocks 5 is internally slidably connected with a sliding tooth 6. The sliding structure of the sliding tooth 6 inside the rotating block 5 is reasonably designed, its surface is smooth, and the matching clearance with the surrounding components is just right. This design allows the sliding tooth 6 to rotate when driven by external force. The movable block 5 slides quickly and smoothly inside and reaches the predetermined position accurately to realize the corresponding fixing or unlocking function, playing a key connection and locking role in the entire disassembly and assembly assembly. The end of the sliding tooth 6 away from the connecting column 4 is fixedly connected with a telescopic spring 8. The telescopic spring 8 is made of high-quality spring steel and has good elastic recovery ability and fatigue resistance. During the disassembly and assembly of the device, the telescopic spring 8 can be flexibly expanded and contracted according to the needs of the operation. For example, when fixing the components, it can rely on its own strong elastic potential energy to stably and forcefully push the sliding tooth 6 towards the fixed position to ensure the firmness of the fixation; and during disassembly, it can contract under the action of appropriate external force, which facilitates the sliding tooth 6 to be separated from the fixed position, making the entire disassembly and assembly process simple and easy, greatly improving the convenience and efficiency of operation.

[0038] The end of the other rotating block 5 away from the counterweight block 3 is fixedly connected to a fixed block 11, and the outside of the fixed block 11 is slidably connected to the inside of one of the rotating blocks 5. The sliding fit between the fixed block 11 and the rotating block 5 is extremely accurate, and the dimensional tolerance between the two is controlled within an extremely small range, so that the fixed block 11 can be accurately embedded in the corresponding position during the sliding process, triggering the subsequent fixed chain reaction, ensuring the accuracy and reliability of the entire disassembly and assembly assembly during connection and fixation, and avoiding problems such as loose connection due to poor fit. A slide groove is provided inside one of the rotating blocks 5. 10, the outside of the sliding tooth 6 is slidably connected to the inside of the fixed block 11, and the outside of the other rotating block 5 is fixedly connected with a latch tooth 12. The shape, size and surface roughness of the latch tooth 12 are strictly designed so that it can perfectly match the latch groove 20 opened on the outside of the connecting column 4. When the latch tooth 12 slides into the latch groove 20, a tight and stable limiting structure is formed between the two, which firmly fixes the connecting column 4 to prevent it from any loosening or movement in the axial direction, ensuring the connection between the motor 19 and the compression block 18 and ensuring the stability of the device during operation.

[0039] The interior of the telescopic spring 8 is provided with a connecting rod 7, and the rear end of the connecting rod 7 is fixedly connected to the front end of the sliding tooth 6. The connecting rod 7 plays an important role in providing guidance and support for the sliding of the sliding tooth 6. It enables the sliding tooth 6 to slide smoothly along a predetermined straight line direction under the telescopic action of the telescopic spring 8, avoiding the situation that the sliding tooth 6 deflects, jams, etc., which affects the fixing effect, and ensures that the function of the entire disassembly and assembly assembly can be smoothly and accurately realized, thereby improving the accuracy and reliability of the disassembly and assembly operation. The other end of the telescopic spring 8 is fixedly connected to the inside of one of the rotating blocks 5, and the end of the connecting rod 7 away from the sliding tooth 6 is fixedly connected to a handle 9. When performing the disassembly and assembly operation, the operator only needs to easily grasp the handle 9 to conveniently apply external force and accurately control the movement of the telescopic spring 8, the sliding tooth 6 and other components, thereby realizing convenient operation of connecting or disassembling the components, without using complicated tools or consuming too much effort, greatly improving work efficiency, and making the entire disassembly and assembly process easy and simple. A slot 20 is provided on the outside of the connecting column 4, and the outside of the slot 20 is slidably connected to the inside of the slot 20.

[0040] Working principle: When the staff needs to install a stabilizing device on the compressor, the driving end of the motor 19 and the connecting column 4 at the bottom end of the compression block 18 are respectively slid into the inside of the counterweight block 1 3 and the counterweight block 2 17. At this time, the two rotating blocks 5 are rotated in opposite directions to make the two rotating blocks 5 fit together. At this time, the fixed block 11 outside one of the rotating blocks 5 will slide into the inside of the slide groove 10 of the other rotating block 5. At the same time, the telescopic spring 8 will push the sliding tooth 6 to slide into the notch of the fixed block 11 to fix it. At the same time, the latch tooth 12 will slide into the inside of the latch groove 20 to limit the latch groove 20. At this time, the quick connection between the motor 19 and the compression block 18 is completed. When the compressor or motor 19 needs to be maintained, repaired or parts need to be replaced, the motor 19 and the compressor can be easily separated, avoiding the trouble of complicated disassembly of the entire connection part, greatly facilitating subsequent maintenance work, reducing equipment downtime, and improving the maintainability and overall operating efficiency of the equipment.

[0041] When the compressor is started, when the speed of the motor 19 fluctuates or the torque changes, the sliding column 13 between the adjustment block 12 and the adjustment block 2 16 will slide inside the slide groove 2 14 of the two. When it suddenly increases, the sliding column 13 will squeeze the buffer block 15 inside the adjustment block 2 16 for buffering. When it suddenly decreases, the sliding column 13 will squeeze the buffer block 15 inside the adjustment block 12, thereby delaying the speed change transmitted to the compressor, avoiding instability of the compressor due to sudden speed changes, and protecting the connecting parts and transmission components of the motor 19 and the compressor.

[0042] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
