Vibration problems of the turbine booster in air separation units
Thread Content
During the regular 6-hour switching of molecular sieves in air separation compressors, it causes increased vibration in the bearings of the turbine and booster; how can this be avoided?
The time when this incident occurred needs to be clarified. Is it a problem that existed from the beginning, or did it arise later on? If it is original, it should be handled by the design institute or the equipment manufacturer. If it appears the day after, it may be related to overproduction. Such as operating under overpressure. For reference.
It is still necessary to clarify when the vibration occurs – during the heating phase of the molecular sieve, during the cooling phase, or during the simultaneous operation phase. It is also important to know how the gas flow rate changes at that time: does it decrease or increase in the case of the compressor? Only by answering these questions first can a detailed analysis be carried out to determine appropriate countermeasures
