BISOPE series 23- Vibration!--1x, 1xTS, 1Order high phenomenon

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

The hypothesis that “resolving the problem of vibration is the same as solving the cause of a mechanical defect” through vibration analysis, that the machine condition is not good when the vibration is high No need.

 

When you first enter the vibration field during equipment diagnosis, you will learn and speak 1X (“ONE X”). Everyone has been thinking about whether to call it “1 times, 1X” until they first hear it being called 1X. Because the book doesn't explain it so easily. Also, in order to find the cause of 10X, it is “one X” that must be understood..

1X, 1X, 1x TS, Order, 1x RPM

 

‘1X’ refers to the first of the components proportional to the turning speed of the machine and is usually expressed in Hz. (If it is RPM, divide by 60.) So 2X is a frequency that is twice 1X, and therefore 10X is a frequency that is an integer multiple of 10 times 1X.

For example, when expressing 90Hz vibration in a motor rotating at 1800rpm, you can say "90Hz amplitude is large, or 5400rpm amplitude is low". This can be conveniently referred to as "3X is greater or lower". In addition, this expression of 'X' can be used more usefully when the number of rotations changes...........................
