Description

Technical Field

[0001] The utility model belongs to the technical field of compression-expansion integrated machine manufacturing, in particular to a rotor auxiliary assembly mechanism of a high-power magnetic suspension compression-expansion integrated machine. Background Art

[0002] Shipping is the main mode of LNG global trade. During the transportation of LNG ships, LNG will inevitably partially evaporate into BOG flash gas. Direct discharge will cause economic losses and greenhouse hazards. Using LNG cryogenic devices to liquefy it is the main BOG treatment method for large LNG carriers. Compared with mixed refrigeration, nitrogen expansion and other technical routes, cryogenic reliquefaction technology has outstanding advantages such as compact system, high efficiency, high reliability and low maintenance cost. Therefore, LNG cryogenic devices are indispensable high-value-added core equipment. At present, the global LNG cryogenic device market is basically occupied by foreign manufacturers such as Air Liquide and CryoStar. Among them, high-power and high-efficiency magnetic levitation compression and expansion integrated machine is one of the core components of the cryogenic device, and it has become a real "neck-stuck" key technology that needs to be solved urgently for domestic substitution. Because the high-power magnetic levitation compression and expansion integrated machine needs to meet the requirements of high power, high speed, explosion-proof, and sealing, the body and core components are large in size and weight, and human power cannot achieve direct flipping of the body.

[0003] At present, most of the existing high-power magnetic levitation compression and expansion machines use manually operated lifting tools to achieve repeated flipping of the casing. On the one hand, repeated lifting using the above method will inevitably lead to safety hazards and the phenomenon of parts knocking and falling. On the other hand, due to the excessive magnetic force of the permanent magnet rotor shaft and the permanent magnet stator, it is easy to cause the installation position to deviate during assembly and it is difficult to adjust, resulting in poor assembly accuracy and low assembly efficiency.
