If the 10X peak is at 2500 CPM, what is the running speed of the machine?

To determine the running speed of the machine based on the given 10X peak value, you need to understand the relationship between the peak frequency and the operating speed of the machine. The 10X peak at 2500 CPM indicates that the vibration frequency observed is a harmonic of the running speed of the machine, specifically the 10th harmonic.

To find the running speed, the peak frequency needs to be divided by 10. In this case, if the 10X frequency is 2500 CPM, you perform the calculation as follows:

2500 CPM ÷ 10 = 250 CPM.

The resulting speed of 250 CPM indicates that the machine operates at that running speed. This reasoning is based on the fundamental principle of vibration analysis that relates harmonics to actual operating speeds; hence, when a 10X frequency is noted, dividing by 10 gives you the fundamental speed of the machine.

Understanding this concept is crucial for vibration analysis, as it helps in diagnosing and addressing issues related to machine performance and vibration signatures. Recognizing harmonics and their corresponding baseline frequencies is a key skill in the field.
