Vibration Analysis Wall Chart Pdf ★

It provides a unified framework for your entire maintenance team, ensuring that junior technicians and seasoned analysts use the same diagnostic references.

Bearings fail in four distinct stages, which are mapped precisely on high-quality charts using specific fault frequencies: Defect on the outer race. BPFI (Ball Pass Frequency Inner): Defect on the inner race.

Let's put the wall chart to use. The following table summarizes the key vibration "fingerprints" for several common faults, a core feature of any good diagnostic chart. Use this as a guide for interpreting the data you see on your analyzer.

A practical chart includes a simplified ISO severity chart for velocity (mm/s or in/s) based on machine class (e.g., Small machines, Rigid foundations, Soft foundations). Vibration Analysis Wall Chart Pdf

Looseness can be structural (base/foundation problems) or fit-related (loose bearing liners, rotating elements). Features a long string of harmonics (

: Protect your printed charts from grease, oil, and moisture in industrial environments.

The vibration analysis wall chart PDF on the wall wasn't just a guide to fixing machines; it was a guide to humility. It reminded him that the machine always told the truth, but you had to know the language to hear it. It provides a unified framework for your entire

What (e.g., pumps, cooling towers, gearboxes) do you target most?

): Always determine the exact rotation speed of the machine first.

Downloading a digital PDF version of a vibration chart offers distinct operational advantages:

Quick equations for calculating bearing frequencies, gearmesh frequencies, and forcing frequencies. 2. Key Machine Faults Featured on the Chart

Characterized by strong 2x RPM radial vibration, with 1x and 3x also present. Phase is 180∘180 raised to the composed with power out of phase radially across the coupling. Mechanical Looseness
