How to deal with compressor vibration
Thread Content
I have a set of circulating hydrogen compressors of the PW.0.61-25-35 model; severe ground vibration occurs during operation, and all alignment measures taken meet the specified requirements. I request the help of all experienced teachers and experts, offering valuable solutions. Thank you
Ground vibrations should be fine, right?
Ground vibration may be a foundation-related issue; it is not necessarily caused by the compressor itself.
On one hand, the foundation involves checking the tightness and levelness of the foot bolts; for the cooling water lines, flexible connections can be used, and measures such as 45-degree elbows or spring supports can be employed to mitigate the impact of pipeline fluids
Look for the epicenter; it is recommended to use the process of elimination.
The simplest solution is to install shock absorbers; there are shock absorbers available for purchase, and you can get in touch with them. For those with high requirements, damping shock absorbers can also be installed.
Is the base a bit too small? We have encountered this problem before as well
Thank you all for your replies. The design institute suggested reinforcing the foundation.
It is likely that there are problems with the foundation aspects, such as uneven shims, foot bolts that are too short or not bent according to specifications, inadequate secondary grouting, insufficient foundation load, and so on. 1. Please have the architectural department of the design institute review the design ； 2. Check the handover documents to assess the status of the civil engineering foundation handover ； 3. Identify the causes on-site and take remedial actions accordingly.
There are also many ways to reinforce it; didn’t the design institute provide a solution?
