BISOPE series 13- Vibration Spectrum Analysis Summary Table (Mechanical Faults)

--------------------------------------------------------------------------------------------------------------------------------------

Order analysis using the vibration spectrum graph is easily used to find out mechanical defects, electromagnetic defects, and fluid-related defects. The initial intention was supposed to have started from the idea that some regularity would be related to mechanical defects through vibration signals, but in fact, most of the rules that are the basis of order analysis can be explained physically. It would be understandable to say that this could be compared to a scientific analysis of human health and disease.

 

Mechanical defects that can be confirmed by vibration spectrum (summary table)

 

Whether or not there is a mechanical defect in the equipment can be checked through the vibration spectrum frequency graph. The table below summarizes the rules of order analysis related to mechanical defects. However, even if you memorize and understand all of this table, you need to understand that the vibration diagnosis of the machine has many problems, so it is only used as a reference for the basics.

 

Item	phenomenon	note
Unbalance	1X(Radial)	Dominates more than 80% of other frequencies, phase is stable
Misalignment	2X, 1,2,3X	180 phase difference in bearings on both sides (note the position and direction)
Bent shaft
