Vibration analysis improves production quality?
IDENTIFYING THE DESTRUCTIVE CAPABILITY OF THE MONITORED MACHINE VIBRATION IS A FUNCTION OF VIBRATION ANALYSIS.
Industry, an immensely important productive sector in the economy, while growing financially, it must also grow in productive methods, whether by expanding its physical location or acquiring more modern equipment.
The maintenance of industrial machinery is expensive and requires a lot of care so that the asset has the necessary reliability to meet the production demand.
To this end, the general advice is that maintenance should be a constant procedure that aims to indicate the risk of machine malfunction, in order to avoid a productive break with unanticipated consequences.
Predictive maintenance is an example of cost-effective maintenance. It catches apparent defects and not yet visible to the naked eye defects.
The maintenance is done based on the analysis of the collected data about the machine’s operation, such as vibration and its resulting heating, for example.
Through Vibration Analysis it is possible to identify defects in machine parts and reverse a possible critical situation.
WHAT IS VIBRATION ANALYSIS?
Vibration analysis is a procedural method of analyzing the performance of moving parts within a machine. The analysis takes place within the range of the rate of dynamic forces variation that are continuously generated.
These same forces affect the characteristic vibrational level of each component (electronic or mechanical). Therefore, with the collection of this data it is possible to verify anomalies that were not even visible at the first analysis, and at the same time without interrupting the use of the machine.
HOW CAN IT BE MEASURED?
Each component has different peculiarities, each piece behaves with different vibrational frequencies. Howerver, each machine component has a continuous frequency amplitude, if this amplitude is in divergence, a mechanical failure is found that could be serious or not.
Vibration measurement can be done using three units: velocity, displacement, and acceleration.
Within the measurement analysis, it is possible to evaluate it from peak to peak, only peaks, rectified average, or by RMS (Root Medium Square).
Among the possible methods to be used, the RMS stands out because it takes into account the time history of the wave and generates a level value that is directly linked to the energy contained in the part being analyzed, in other words, it is possible to obtain an analysis of the destructive capacity of the vibration.
The maintenance costs, depending on the industry, can reach up to 30% of the production cost.
Unnecessary breaks reveal weaknesses in obtaining information about the machine’s health, generating production costs, labor, equipment, materials, and sometimes the replacement of parts that are still in good condition but were wrongly detected as defective.
All maintenance-related costs can be reduced and often even avoided if the condition of the machine or equipment is monitored based on actual data that determines the need to pause for the replacement or maintenance of parts or components on the machinery.
Therefore, vibration analysis is a mechanism for maximum efficiency when it comes to performing maintenance.
The occurrence of irregular amplitudes within a continuous frequency solidifies the costly decision to shut down machinery and the production sector. Thus, there are considerable savings in production and maintenance expenses.
