33- Simple vibration diagnosis and precision vibration diagnosis of rotating
machinery
--------------------------------------------------------------------------------------------------------------------------------------
The results of the vibration diagnosis can be confirmed
as a technical report, which is largely divided into a simple diagnosis report
and a detailed diagnosis report, etc., and is prepared including the cause and
evaluation of the current vibration problem, and a description of
countermeasures if necessary. The meaning of each report is a simple report in the case of
simple evaluation of phenomena and absolute standards after temporary
measurement, and detailed analysis to the extent that current causes can be
analyzed and countermeasures can be found through spectrum analysis and cause
analysis of various vibrations. are treated as detailed reports. In general, the
definition of regular textbooks for facility diagnosis qualifications is not
very different.
Simple diagnosis and precise diagnosis,
offline and online
First of all, if you look at the methods of simple
diagnosis, there are 'route measurement' and 'online monitoring system'. Inspection is commonly
referred to as 'off-line' as a method in which humans intermittently
investigate and record the state of equipment using a portable instrument
(vibration meter, data collector). On the other hand, constant monitoring is a method of
continuously monitoring by a monitoring device and is called 'on-line'. Inspection called
off-line can measure many measurement points and directions, but it cannot be
said to be continuous depending on the frequency of measurement. There are
advantages and disadvantages between the two systems, since on-line
continuously monitors and stores near real-time data from already installed
sensors.
