Many industry experts and OEMs offer high-quality, free PDF wall charts.
The heart of any high-quality PDF wall chart is its diagnostic matrix. Here are the primary faults covered, along with their characteristic spectral and phase footprints: 1. Unbalance
: Natural frequencies of bearing components ring out; minor sidebands appear.
Do you need a chart focused on or advanced bearing/gearbox diagnostics ?
Before analyzing any peaks, determine the exact rotational speed of the machine. If a motor turns at 1,800 RPM, then
These charts help in determining if the issue is mechanical or electrical. Limitations
Color-coded velocity and acceleration limits to determine if immediate action is required. Core Fault Frequencies Featured on a Wall Chart
RPM in the direction. Phase shift across the coupling is approximately 180∘180 raised to the composed with power Parallel Offset Misalignment: Characterized by high
Color-coded indicators or rules of thumb for velocity and acceleration levels. 2. Deciphering the Core Fault Signatures
Visual graphs showing where peaks appear relative to the running speed (
Charts help you differentiate between similar-looking problems. For instance, both unbalance and bent shafts cause high
