Measurement Testing

Critical industrial equipment (e.g., pumps, motors, compressors, fans and spindles) can be monitored by vibration analysis. Specific components include:

Pump bearings
Fan unbalance
Screw compressors
Spindle bearings

Here are some applications:

Shaft unbalance

The vibration-analysis tool should detect unbalance at an early stage. Condition diagnosis allows predictive action to prevent serious damage or downtime. To monitor unbalance, the rotational speed is required as a parameter.

Bearings

causes of failure: wear, misalignment, lubrication problems. The vibration-analysis tool should, for example, monitor the inner race, outer race and rolling elements of a bearing. In order to monitor the critical frequencies the vibration-analysis tool needs the following data:

* bearing specs (e.g., number of rolling elements, rolling element diameter and pitch)
* diameter or DIN number
* Rotational speed (rpm)
