The purpose of condition monitoring inspection is to follow the way of equipment to detect the symptoms of faults.
- The basis of a condition monitoring system is made up of the inspection actions that regularly takes place in the machinery and equipment.
- these actions, that they are at stake not only the inspector's directions, but also a number of specific techniques, It aims to determine the evolution of the equipment operating conditions.
- Each has advantages and defects, beyond its own limitations.
- Its application implies, therefore, a knowledge of all the factors at play, It is common to apply more than one technique on each machine, either as a parameter to follow a trend, want to check the condition.
- When selecting a control technique for a critical machine, It is important to note that the machines malfunctioned because one or more critical components fail.
- Therefore, the most sensitive methods of inspection machine, running through fault detection in individual symptoms components, seen the greatest deviation from normal conditions to be focused on these symptoms making it easier to detect abnormalities.
- The selection of a control method therefore depends on the type of components susceptible to damage and how this occurs.
- One can then consider the possible hypotheses to control the degradation of these components and may even be possible to find a technique that can only detect any failures likely type of a machine with reasonable efficacy.
- On the other hand, the specific situation of maintaining each plant will impose some constraints on the choice of inspection techniques to implement.
