Vibration fluctuations at the second and third stages of the Cooper TA48 compressor
Thread Content
The vibration of the Cooper compressor TA48 exhibits intermittent fluctuations, primarily occurring at stages 2 and 3. Since these stages share the same shaft, it is likely that there is no issue with the instrument signals. After some time of such fluctuations, the vibrations at stages 2, 3, and 4 reach levels of 0.5/0.8/0.9 mils respectively. Currently, these fluctuations occur frequently enough to reach the interlock threshold, causing the compressor to stop operating. Please help to resolve this issue; thank you very much
There are various factors that can cause vibration. When encountering such issues, the process-related factors should be ruled out first, after which the machine needs to be stopped and disassembled for inspection. Regarding the process, it is necessary to check the process parameters to see if there are any discrepancies. . . . . . Mechanical issues such as excessive bearing clearance, problems with shaft alignment, and lubrication problems. . . . . If it doesn’t work, don’t force it; as long as the process-related issues can be ruled out, the problem must lie with the equipment itself, and then it needs to be stopped. . . . . The specific responsibilities are thus assigned. If you stop and find that it’s a problem within your area of expertise, then you shouldn’t stop.
