| Abstract: | The failure in control of the deviation of guide blade of 60000 m3/h air separation plant-completed Model VK200-3 air compressor and the irregular movement of stage-I guide blade results in shutdown of the air compressor because of exceeding the limit of stage-I shaft vibration.The trouble is completely eliminated through reforming the control of air compressor guide blade and fixing the opening of stage-Ⅱ and stage-Ⅲ guide blade,and thus the air separation plant is kept at safe and steady operation.The structure of Model VK200-3 air compressor is briefed and the analysis and treatment process of the shutdown trouble is detailed. |
