Predictive maintenance Part I – Industry 4.0

The strategy that predicts when machinery will
require maintenance

“Damage can always be prevented if appropriate steps
are taken in due time.” There’s no better way of describing the main benefit of
predictive maintenance.

The principle is based on three pillars:

1. Permanently monitoring the condition of a
“healthy” system to detect wear or variations from the normal condition early
on – fluid condition monitoring

2. If a variation is detected, in the simplest case
only an alert is issued, but a better option is to determine and output the
remaining service life of a component or a subsystem – as per Industry 4.0

3. On the basis of this “condition” of the system,
costly downtime can now be reliably avoided and inexpensive maintenance can be
scheduled.

This type of “condition-based” strategy creates the
conditions for enabling negative changes in hydraulic and lubrication systems
to be detected early on and countermeasures to be initiated in due time.
Virtually every fluid system comes with a multitude of ways to consistently
monitor the condition of the fluid and save on unnecessary costs.
