Check the operating condition of the urea carbon dioxide turbine rotor

What specific situation is the poster referring to? 1. Runtime. . . For example, how often is it necessary to perform maintenance or replace tiles? 2. Problems that occurred during operation. . . Changes in amplitude or thrust? 3. Effect of changes in process parameters on the rotor. . . 4. Balance after blade structure adjustment. . . Wait. When our factory was in normal operation, it generally underwent a major overhaul every one and a half years to replace the tiles. There was once an instance during normal operation when the shaft suddenly rose. Upon shutdown for inspection, it was found that in one case the thrust bearing pads were installed in the wrong direction, which prevented proper oil film formation and led to wear of the pads ； Once, it was suspected that the loss of a balance weight had caused imbalance in the rotor ； Once, after a surge shutdown, \"free rotation\" occurred again, causing damage to the bearings. . .
