The invention discloses a rotor dynamic balance adjustment method and device of a centrifugal compressor, relates to the technical field of centrifugal compressors, and can realize online dynamic balance of the rotor. The method includes: during the operation of the centrifugal compressor unit, monitoring the vibration state of the rotor of the centrifugal compressor in real time; if the vibration state meets a preset vibration alarm condition, obtaining the rotor dynamic Balance the phase and quality of the biased weight; according to the phase and quality, send an online dynamic balance adjustment command to the pre-configured dynamic balance device on the rotor, so that by adjusting the counterweight balance block in the dynamic balance device, the above The rotor is dynamically balanced online. The invention is suitable for the rotor dynamic balance adjustment of the centrifugal compressor.
Description
technical field [0001] The invention relates to the technical field of centrifugal compressors, in particular to a rotor dynamic balance adjustment method and device of a centrifugal compressor. Background technique [0002] Centrifugal compressors are generally multi-stage, which can make the gas obtain higher pressure. In some centrifugal compressors, due to technological reasons, the process gas will undergo polymerization reaction and produce coking. For example, the product gas contains olefins and high-carbon gases. When compressed, due to the increase in temperature, coking will occur, and the coke will stick. The aerodynamic performance of the centrifugal compressor is seriously affected on the impeller, diffuser and other centrifugal compressor flow passages and components. The uneven coverage of the coke or the sudden shedding of parts will affect the balance of the rotor of the centrifugal compressor, which will cause the centrifugal compressor to vibrate beyond ...
