Measuring techniques
The concept of strategic condition monitoring is quite simple. The types of mechanical faults which can occur on a given machine are well known to your maintenance personnel. What they need is, first: a straightforward message that a fault is developing, and second: an indication of its severity.
There is no single method which can measure everything at a reasonable price. However, if you define the target (the expected machine fault, which you must do in any case), you can easily pick the monitoring method which will provide the fastest, cheapest, and most reliable result.
Bearing monitoring (SPM® Method)
The primary targets are rolling bearings (damage and lubrication condition). In many applications, these are the only machine elements which need monitoring. The method also reacts to shaft misalignment, cavitation, and other faults. It requires little input data and is fast and easy to apply.
Bearing analysis (SPM Spectrum™)
Shocks generated by damaged bearings will typically have an occurrence pattern matching the ball pass frequency over the rotating race. Shocks from e. g. damaged gears have different patterns, while random shocks from disturbance sources have none.
Vibration severity measurement
Very efficient for detecting the most common machine faults, such as imbalance, structural weakness, loose parts. Little input data needed, easy to apply.
Vibration spectrum analysis (EVAM® Method)
Requires considerably more input to make sense of the data but, used in connection with our comprehensive analysing software, allows you to target difficult problems where other methods cannot give accurate answers.
Balancing
Balancing can be performed with handheld instruments as Leonova or T30. Descriped here is the balancing functions of Leonova. For more information about balancing please contact your local SPM office or read more in your instrument manual.
Shaft alignment
Shaft Alignment is an optional Leonova™ Infinity function for quick and easy shaft alignment, with either limited or unlimited use. In case of limited use, credits are deducted for each alignment assignment. The function is user-friendly and easy to learn.
