Seeking help with vibration problems
Thread Content
There are 5 cooling towers; one of the reducers exhibits excessive vibration. It is suspected that there is a problem with the sensor, but when the sensor is used on other reducers, the readings are normal. Conversely, when the sensor from those other reducers is used on this reducer, the readings become abnormal, and the same situation occurs when the channels are swapped. But when using a magnetically attached vibration meter to measure the reducer, the vibration levels are not above the acceptable limit; I’m not sure why I need some help.
It is recommended not to overlook this; the reducer needs to be checked.
I wonder if it’s possible to use human senses to try this out, that is, by using a stethoscope or touching the area to check for any abnormalities. Generally speaking, human perception can be considered quite reliable for making judgments; as long as it’s possible to use it, it’s worth giving it a try.
It can only be inserted into the cooling tower while it’s in operation; it’s too dangerous.
It is also possible to listen to the areas where the brackets move during operation on a macro level, but this requires familiarity gained through regular inspections; by listening frequently, one can learn to identify abnormal sounds. I’m not sure what your cooling tower looks like; if it has a variable speed drive, it should be taken apart for inspection and maintenance, and regular maintenance checks should also be scheduled. For reference.
What was said on the 4th floor is correct; it’s a dangerous situation that isn’t allowed, and the second owner wouldn’t approve of it either.
We have also encountered situations where the shield wire was properly grounded.
There is no main control room for the shielded wires at all; the shielded wires coming from the probes were cut off
If I do the math, this probe also has oil temperature and oil level readings
