Vibration Analysis / Condition Monitoring
The Pruftechnik VibXpert data collector with OmnitrendSoftware is also utilized to perform vibration analysis on a multitude of equipment. Our technicians can analyze collected data and provide reports that identify problems in the very early stages of failure. Trending this data over periods of time is also a powerful tool, allowing our customers to schedule repairs, thereby avoiding downtime and costly emergency repairs.
Vibration Monitoring is one of the most useful Condition Monitoring techniques available to maintenance technicians as early identification of problems such as Imbalance, Bearing Faults, Misalignment and Gear Tooth Mesh problems are critical factors in ensuring and extending the working life of machinery.
Rotating Mechanical Solutions use Vibration Monitoring to monitor the health of rotational equipment.
This involves the trending and analysis of certain machinery performance parameters to detect and identify developing problems before failure occurs, causing extensive damage. The detection and diagnosis of faults before they become a problem is obviously the most desirable way to maintain machinery. An effective condition-monitoring program will help to detect faults at an early stage such as when rolling element bearing defects are still minor and do not affect the performance of the machine. This allows time to analyze the problem while the machine stays online and production continues normally. This advance warning allows planning of the repair at a convenient time.
As part of an overall Asset Management Strategy, Condition Monitoring is the process of monitoring a parameter of condition in machinery, such that a significant change is indicative of a developing failure. It is a major component of predictive maintenance and allows maintenance to be scheduled or other actions to be taken to avoid the consequences of a failure, before the failure occurs.
Condition Monitoring is used to indicate a deviation from a reference value (e.g. temperature or vibration behavior) to identify impending failure.
Condition Monitoring is more cost effective than a run to failure maintenance policy as it reduces/minimizes direct maintenance cost:
It reduces/eliminates indirect costs from lost production due to unscheduled downtime from an in-service failure.
A major component of predictive maintenance, it is a process of monitoring a parameter of condition in machinery.
Electric Motor Evaluation
Online testing (performed while the motor is in operation) and offline testing (performed on deenergized motors) can provide critical information to the overall health and condition of an electric motor, including insulation testing (resistance to ground and capacitance to ground), motor circuit analysis, and power quality.
Based on the results of these tests, recommendations can be made as to what corrective actions need to be made.
