Description

Technical Field

[0001] This utility model belongs to the field of oil and gas production technology, and more specifically, it relates to a vibration-damping control cabinet for mobile FMC multiphase compression equipment. Background Technology

[0002] FMC (Fuel-Modulated Compression) multiphase compressors are devices used in specific industrial applications, primarily for processing gases or liquids. They improve efficiency and reduce energy consumption through multiphase compression technology. In the oil and gas industry, FMC multiphase compressors are commonly used for natural gas compression and transportation, improving the production efficiency of oil and gas fields.

[0003] In operation, to enable the FMC multiphase compressor to automatically determine the appropriate critical flow rate and automatically set the compressor speed required for that flow rate, thus achieving continuous and stable gas well production and long-term production increases, a PLC integrated into the system control cabinet is necessary. For example, Chinese invention patent CN111271026B describes equipping the FMC multiphase compressor with a PLC control cabinet. To achieve PLC control, numerous controller modules need to be integrated within the control cabinet. Due to this integrated design, the compressors and pumps within the FMC multiphase compressor will vibrate during operation. This vibration may cause wiring connections or solder joints within the control cabinet to break, resulting in poor contact or damage to electrical components, affecting the normal operation of the equipment and even causing production stoppage. Furthermore, continuous vibration can loosen the mechanical structure of the PLC control cabinet, affecting its stability and lifespan.

[0004] To avoid the impact of vibration on the PLC control cabinet, vibration reduction measures need to be implemented to ensure the stable operation of the FMC multiphase compressor. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a vibration-damping control cabinet for mobile FMC multiphase compressor equipment. This solves the technical problem in the prior art where the bumps and vibrations during the movement and operation of the FMC multiphase compressor equipment cause breakage of wiring positions or solder joints of electrical components inside the control cabinet, resulting in poor contact or damage to electrical components, thus affecting the normal operation of the equipment.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A vibration-damping control cabinet for a mobile FMC multiphase compression device includes a cabinet body and a mounting plate for installing a controller module. The key feature is that the mounting plate is floatingly installed inside the cabinet body via an elastic mechanism. The compression and extension of the elastic mechanism mitigates impact, maintaining the mounting plate in a relatively stable state. The mounting plate is vertically positioned and has at least one tuned mass damper mounted on it. The tuned mass damper includes a reed with a mass attached to it. During vibration, the oscillation of the mass reduces the displacement amplitude of the mounting plate. The mass generates inertial force, interacting with the vibration of the structure, thereby consuming the vibration energy of the structure and achieving vibration reduction.

[0008] Optionally, the elastic mechanism includes at least one set of horizontal slide rods, a sliding frame is slidably mounted on the horizontal slide rods, at least one set of vertical slide rods is provided on the sliding frame, the mounting plate is slidably mounted on the vertical slide rods, and springs are provided on the moving paths of the sliding frame and the mounting plate, which can be compressed and extended to relieve impact.

[0009] Optionally, the elastic mechanism includes multiple springs, which suspend the mounting plate within the cabinet.

[0010] Optionally, a keel frame is provided inside the cabinet, and the mounting plate is installed on the keel frame.

[0011] Optionally, the mass is a magnet, and an induction coil corresponding to the magnet is installed inside the cabinet. When the magnet swings, the induction coil cuts its magnetic field lines to generate an induced current. By analyzing the generated induced current, the vibration of the control cabinet can be determined.

[0012] Optionally, there are multiple tuned mass dampers, which are respectively arranged on both sides, top and bottom of the mounting plate.

[0013] Optionally, the induction coil is connected to a current detection module.

[0014] Optionally, multiple springs are located around the mounting plate.

[0015] Optionally, the control cabinet is integrated into the FMC multiphase compression device.

[0016] Optionally, the mounting plate is provided with mounting rails for mounting the controller module.

[0017] This utility model provides a vibration-damping control cabinet for mobile FMC multiphase compression equipment, which has the following advantages:

[0018] 1. The mounting plate is floating inside the cabinet through an elastic mechanism. When subjected to pressure or vibration, the compression and extension of the elastic mechanism can alleviate the impact, maintain a relatively stable state, reduce the possibility of loosening of the controller module connection, and ensure the stable operation of the equipment.

[0019] 2. By installing a tuned mass damper on the mounting plate, when the mounting plate is subjected to external forces, the tuned mass damper will absorb and disperse the energy of these forces, slow down the swing speed of the mounting plate, and further maintain the relative stability of the mounting plate.

[0020] 3. By setting the mass block as a magnet and setting an induction coil corresponding to the magnet inside the cabinet, the vibration of the control cabinet can be determined by the swing of the magnet causing the induction coil to cut its magnetic field lines. Attached Figure Description

[0034] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0035] This utility model provides the following technical solution:

[0036] Example 1:

[0037] A vibration-damping control cabinet for a mobile FMC multiphase compressor is disclosed. The control cabinet 1 is integrated into the FMC multiphase compressor; this integrated design reduces the overall size and facilitates subsequent relocation. Figure 1 , Figure 2 As shown, the control cabinet 1 adopts a conventional cabinet 10, which contains a mounting plate 11 for installing controller modules (electrical components). The mounting plate 11 is vertically oriented and has mounting rails 110 for installing the controller modules. The controller modules are then installed on the mounting plate 11. To improve the stability of the installation structure, a frame 17 is provided inside the cabinet 10, and the mounting plate 11 is installed on the frame 17.

[0038] Due to its integrated design, the FMC multiphase compressor equipment generates vibrations during operation, including from the compressor and pump. To address the issue of loose connections in the controller module within control cabinet 1 caused by these vibrations, [further measures are needed]. Figures 3-5 As shown, this solution involves floating the mounting plate 11 inside the cabinet 10 using an elastic mechanism. During implementation, the mounting plate 11 can mitigate impacts from pressure or vibration through the compression and expansion of the elastic mechanism, maintaining a relatively stable state and reducing the possibility of loosening of the controller module connection.

[0039] Specifically, such as Figure 4 , Figure 5As shown, one type of elastic mechanism in this solution, the "sliding frame type," includes at least one set of horizontal slide rods 13. A sliding frame 14 is slidably mounted on the horizontal slide rods 13. When subjected to force, the sliding frame 14 can move horizontally. At least one set of vertical slide rods 15 is provided on the sliding frame 14. A mounting plate 11 is slidably mounted on the vertical slide rods 15. When subjected to force, the mounting plate 11 can move vertically. Springs 16 are provided along the movement paths of both the sliding frame 14 and the mounting plate 11. During implementation, the springs 16 can alleviate impact through compression and extension, thus maintaining the mounting plate 11 in a relatively stable state.

[0040] To further suppress the vibration of the mounting plate 11, such as Figure 2 , Figure 3 As shown, at least one tuned mass damper 12 is mounted on the plate. It dissipates energy by providing kinetic resistance, thereby suppressing the vibration of the mounting plate 11. In practice, when the mounting plate 11 is subjected to external forces, the tuned mass damper 12 absorbs and disperses the energy of these forces, slowing down the swaying speed of the mounting plate 11 and keeping it relatively stable.

[0041] For a detailed explanation of the working principle, please refer to: Basic Principles and Working Mechanism of Tuned Mass Damper 12 (TMD). A TMD is a passive control device composed of a mass block, elastic components, and a damper. Its basic principle is to add a mass block to the structure, making it close to the structure's natural frequency, thus forming a resonant system. When the structure is subjected to external excitation, the mass block generates inertial force, interacting with the structure's vibration and thereby dissipating the structure's vibrational energy, achieving vibration reduction.

[0042] The working mechanism of the TMD mainly includes two aspects: first, it resists the vibration of the structure through the inertial force of the mass block; second, it provides restoring force through the elastic restoring force of spring 16. The damper is used to dissipate vibration energy and reduce the vibration response of the structure. By rationally designing the parameters of the TMD, it can achieve the maximum vibration reduction effect under the main vibration modes of the structure.

[0043] like Figure 6 As shown, the structure of the tuned mass damper 12 in this scheme includes a reed 121 and a mass 122 disposed on the reed 121. During vibration, the displacement amplitude of the mounting plate 11 is reduced by the swing of the mass 122.

[0044] In addition, such as Figure 2 , Figure 3 As shown, block 122 is a magnet, and an induction coil 18 corresponding to the magnet is installed inside the cabinet 10. Figure 7 , Figure 8As shown, when vibration occurs, the mass 122 will oscillate. This oscillation of the magnet causes the induction coil 18 to cut its magnetic field lines, generating an induced current. The induction coil 18 is connected to a current detection module, which monitors parameters such as the frequency and voltage of the induced current to determine the vibration status of the control cabinet 1. Specifically, the frequency of the current reflects the vibration frequency of the control cabinet 1, and the amount of current generated reflects the amplitude of the vibration. This allows for the determination of the vibration status of the control cabinet 1 by analyzing the generated induced current.

[0045] To ensure vibration reduction effectiveness and monitoring reliability, such as Figure 2 , Figure 3 As shown, there are multiple tuned mass dampers 12, which are respectively arranged on both sides, top, and bottom of the mounting plate 11. In practice, the multiple tuned mass dampers 12 can balance vibrations in multiple directions, and the multiple induction coils 18 matched with them can also collect vibration data from multiple parts of multiple control cabinets 1. The collected data can be comprehensively analyzed, verified, and the reliability of monitoring can be ensured.

[0046] Example 2:

[0047] The difference between this embodiment and Embodiment 1 lies in the different elastic mechanism, such as... Figure 9 As shown, the "spring-type" elastic mechanism used in this embodiment includes multiple springs 16, which suspend the mounting plate 11 within the cabinet 10. Specifically, the multiple springs 16 are located around the perimeter of the mounting plate 11. In practice, the springs 16 on both sides and the bottom of the mounting plate 11 support it, while the springs 16 at the top of the mounting plate 11 pull it. This method results in a simpler structure and greater freedom of movement for the mounting plate 11.
