Vibration problems causing vibration in catalytic flue hoods
Thread Content
The vibration issue that causes vibration in catalytic smoke extractors: Is there a correlation between the vibrations indicated by our instruments and those measured using vibration detectors on the exterior equipment housings? What is the highest level of housing vibration you have ever measured on-site?
Vibration of smoke extractors generally refers to shaft vibration and shaft displacement data; measuring the housing can only provide indirect indications of these values, and such readings are for reference only.
The vibration value displayed on the DCS is in um, while the vibration (velocity) of the housing measured on-site is in mm/s; there is a certain relationship between the two. For example, our on-site measurement was 1.9, while the DCS showed 30. It can only be used as a reference, after all, the measurement points for the two are different.
If both values increase, it proves that the vibration of the smoke extractor has indeed increased.
The indoor values are within the acceptable range now, but the on-site vibration readings exceed 10
Contact the instrumentation to verify whether that measurement is accurate; if the actual vibration level increases, it will be noticeable on site, as the platform will vibrate noticeably.
If the shaft vibration is not high but the vibration at the site is significant, it indicates that there are many external factors; analyze what causes the shell vibration.
There are various reasons for on-site vibration measurement, such as issues with the vibration meter, the measurement points, the measurement methods, and environmental influences. There is more than one vibration measurement point in a DCS; it’s impossible for them all to fail at the same time. 1. Try using a different vibration detector and a different vibration measurement point; also check other areas to see if there is vibration there. 2. Have an instrument checked the measurement points to see if there are any issues.
The vibration is indeed intense; the platform shakes so much that it makes your feet numb
