Centrifugal compressor
Thread Content
There is a type of compressor used in this facility, a centrifugal multi-axis, multi-stage compressor with coolers between the stages. Recently, these centrifugal compressors have been experiencing ultra-low frequency vibrations, and the vibration levels in the connected pipelines increase several times as well. What could be the possible causes?
Check if there is slight surge? ~~
No, it’s around 270 T/H of air
Is this compressor old? If it has been well maintained, it’s hard to determine the technical condition
In this situation, bearing damage causes wear inside the rotor, resulting in imbalance of the rotor. It is recommended to stop the machine immediately for inspection and repair; continuing to operate it can lead to serious accidents.
The bearing vibration is not particularly high, ranging between 10–30 UM
There are fluctuations in the vibration of this rotor; if it operates at high speeds for a long time, it will definitely cause damage to the bearings
Another possibility is that there are loose parts inside your rotor!
