Description
Technical Field
[0001] This utility model relates to the field of helium compressor technology, specifically to a disassembly device for the installation and maintenance of helium compressors. Background Technology
[0002] The helium compressor is a horizontal, high-speed, high-pressure-ratio, variable-frequency unit. The high-temperature gas-cooled reactor adopts a dual-reactor, single-unit overall layout, with both reactors sharing a single fuel sphere helium delivery system. This system includes two parallel-connected helium compressors, which can operate simultaneously or independently. During normal reactor operation, one compressor is in operation, while the other is on standby. The helium compressor system is capable of delivering fuel spheres, delivering absorber spheres, and delivering helium during emergency dehumidification and low-flow-rate core cooling operations. The helium compressors perform various functions as needed, but not multiple functions simultaneously.
[0003] High-temperature gas-cooled reactors (HTGRs) will become an important reactor type for my country's future nuclear power development. They can achieve very high operating temperatures and output high-temperature helium. Besides efficient power generation through various methods such as direct gas cycle, indirect gas cycle, and steam cycle, they can also be used for various process thermal applications, including hydrogen production, coal gasification and liquefaction, heating, and seawater desalination. Based on their inherent safety characteristics, consideration can be given to eliminating off-site nuclear emergency response, narrowing the planning restriction zone, and bringing them closer to users, increasing the adaptability of site selection. High steam output parameter cogeneration can meet the clean heating needs of industrial steam supply and heating in industries such as steel, chemical, papermaking, and printing and dyeing. They also have potential applications in areas such as ultra-high temperature hydrogen production, distributed auxiliary power generation, and clean replacement of decommissioned coal-fired power plant boilers, all within the comprehensive utilization of nuclear energy.

[0043] This disassembly device for the installation and maintenance of a helium compressor involves the following steps: During disassembly, the impeller end external self-aligning bracket 1 is installed on one side of the compressor. Then, the electromagnetic bearing-related components are removed and temporarily placed in the position of the self-aligning device 10. After installing and fixing the semi-circular fixing sleeve 4, the impeller end external self-aligning bracket 1 and the self-aligning device 10 are adjusted. After removing the electromagnetic bearing-related components, the impeller end external self-aligning bracket 1 and the self-aligning device 10 are re-fixed. The semi-circular fixing sleeve 4 is removed, and the slide rail 3 and the inner sliding plate 6 are installed.

[0044] The slide rail 3 and the inner fixed plate 25 work together to ensure balanced force distribution and prevent uneven force distribution from damaging the internal components of the compressor.
[0045] This disassembly device for the installation and maintenance of helium compressors meets the installation and maintenance requirements of helium compressors in the high-temperature gas-cooled reactor demonstration project, significantly improves the installation and maintenance efficiency of helium compressors, reduces the input of manpower and material resources, strictly limits the radial displacement of the rotor part during the entire disassembly process to avoid collision damage, and the external dimensions of the device fully meet the on-site working conditions and space constraints.
[0046] In this embodiment, the tension rod 2 positions the inner sliding disc 6 through the limiting pin 20, thereby ensuring the stability of the inner sliding disc 6 when it is not required to slide.
[0047] The tension rod 2 has multiple members, which are radially spaced along the outer self-aligning bracket 1 at the impeller end. This arrangement ensures the stability of the inner sliding disc 6 mounted on the tension rod 2 and prevents sliding or tilting.
[0048] Specifically, the self-aligning device 10 includes a connecting base 101, an adjusting screw 102, a sliding tube 103, and a limiting ring 105. The connecting base 101 is connected to the impeller end external self-aligning bracket 1, and a connecting protrusion 104 is provided on the side wall of the connecting base 101. The middle part of the connecting base 101 has a sliding cavity 107, and a sliding groove 108 is provided on the side wall of the connecting base 101.

The adjusting screw 102 is inserted into one end of the connecting protrusion 104 and the sliding tube 103, and the sliding tube 103 is connected to the adjusting rod 110.
[0049] The self-aligning device 10 can be fixed by connecting the connecting base 101 to the impeller end external self-aligning bracket 1. At the same time, a sliding cavity 107 is provided in the connecting base 101, and a connecting protrusion 104 is provided on the connecting base 101, so that the sliding tube 103 can be placed in the sliding cavity 107. Then, the adjusting screw 102 is used to connect the sliding tube 103 and the connecting protrusion 104 at the same time, so that the connecting base 101 and the sliding tube 103 are connected into a whole. Then, the sliding tube 103 is connected to the adjusting rod 110, and then connected to the spindle 11. Thus, the position of the spindle 11, that is, whether it is concentric with the impeller end external self-aligning bracket 1, can be adjusted by moving the adjusting screw 102.
[0050] The sliding tube 103 is provided with an adjusting protrusion 106, which is located in the sliding groove 108. One end of the adjusting screw 102 is rotatably connected to the connecting protrusion 104, and the other end is threadedly connected to the adjusting protrusion 106.

The connection between the connecting base 101 and the sliding tube 103 is achieved by using the adjustment protrusion 106.
[0052] In some optional embodiments, the adjusting screw 102 is provided with a limiting ring 105, which is used to prevent the adjusting screw 102 from moving relative to the connecting base 101, thereby ensuring the connection stability of the adjusting screw 102 relative to the connecting base 101.

[0055] Meanwhile, one side of the adjusting rod 110 is connected to a threaded sleeve 111 by a bolt, and the threaded sleeve 111 is used to connect to the spindle 11. That is, by using the threaded sleeve 111 to thread one end of the spindle 11, the adjusting rod 110 is connected to the spindle 11, thereby realizing the connection between the adjusting rod 110 and the spindle 11, and thus realizing the connection between the self-aligning device 10 and the spindle 11.
[0056] In some alternative embodiments, the outer sliding disk 5 is provided with a handle 9.
[0057] The handle 9 is designed to facilitate operation of the external sliding disk 5, providing an operating reference for the operator.
[0058] The disassembly device for installing and maintaining a helium compressor also includes an external self-aligning bracket 7 at the motor end. This bracket 7 is located on the other side of the compressor, specifically the right side, and can be adjusted as needed during actual use. The external self-aligning bracket 1 at the impeller end and the external self-aligning bracket 7 at the motor end are connected at both ends of the compressor.
[0059] When the motor end external self-aligning bracket 7 is installed, the motor end can be disassembled. The specific disassembly process is the same as that for the impeller end.
[0060] The specific disassembly method for the disassembly device used for the installation and maintenance of a helium compressor is as follows: Install the impeller end external self-aligning bracket 1, then remove the electromagnetic bearing-related components and temporarily place them in the position of the self-aligning device 10. After installing and fixing the semi-circular fixing sleeve 4, adjust the impeller end external self-aligning bracket 1 and the self-aligning device 10. After removing the electromagnetic bearing-related components, re-fix the impeller end external self-aligning bracket 1 and the self-aligning device 10, and remove the semi-circular fixing sleeve 4. Install the slide rail 3 and the inner sliding disc 6, then install the tension rod 2 and tighten it with the threaded hole of the internal electromagnetic bearing housing. Finally, install the inner sliding disc... 6. Move the tension rod 2 to the vicinity of the end and fix it with the limit pin 20. Use manual push-pull operation or set screw external pull operation to move the electromagnetic bearing housing out. Fix the semi-circular fixing sleeve 4. Remove the impeller end external self-aligning bracket 1. Use a crane to transport the electromagnetic bearing housing out. Reinstall the impeller end external self-aligning bracket 1, slide rail 3, and inner sliding plate 6. Remove the semi-circular fixing sleeve 4.
