Description

Technical Field

[0001] The present application relates to the technical field of centrifugal compressors, and in particular to a compressor rotor bracket capable of automatically turning. Background Art

[0002] In the field of compressor technology, the compressor rotor is the core component of power transmission and gas compression. The stability and reliability of its performance are crucial to the operation of the entire compressor system. In the daily maintenance and overhaul of the compressor, cranking operation is an indispensable and important link. Cranking is to rotate the compressor rotor slowly and evenly through a specific device. This operation not only helps to check the balance of the rotor, the wear of the bearings and the effectiveness of the lubrication system, but also prevents the rotor from deformation or sediment accumulation due to gravity by rotating it after a long period of shutdown, ensuring that the rotor can quickly reach the best working state when restarting.

[0003] The rotor bracket is an important auxiliary tool in the manufacturing, storage and maintenance of compressor rotors. Its design and function directly affect the handling efficiency and maintenance quality of the rotor. Although the traditional compressor rotor bracket can meet the basic requirements of stably supporting the rotor, due to the large size and amazing weight of the compressor rotor, it is impossible to turn the rotor manually. In actual operation, it is usually necessary to use lifting equipment to cooperate with other personnel, which is difficult to operate, time-consuming and labor-intensive, and greatly increases the difficulty of compressor maintenance, so it needs to be improved.
