MAINTENANCE PROGRAM DEVELOPED BY OSLINGER S.A.S
PREVIOUS CONSIDERATIONS
Technical Asset Management is an approach that allows alignment of maintenance expenses of the assets with the economic objectives of the company.
Companies use Asset Management to reduce costs, manage risk and achieve economic, quality and environmental objectives.
Result: a set of spending decisions that maximize the shareholder's profit considering the available budget for investments.
Oslinger S.A.S applies the following techniques and tools as support to the Technical Asset Management of our Clients:
Diagnosis offline and online.
Monitoring of the condition.
Identification, control and risk management.
Condition based maintenance.
Increased Loadability (designing again) ("Up-grade", "Up-rated")
DEFINITION OF MAINTENANCE PROGRAM BASED ON CONDITION (MBC)
1. IDENTIFICATION OF FAILURE MODES
Previo al mantenimiento, Ingenieros expertos de nuestra empresa realizan inspección visual detallada interna, externa, diagnóstico eléctrico y mecánico del equipo, ya sea en línea o fuera de línea con equipos de última generación y tecnología de punta para determinar la existencia de fallos incipientes.
Es ampliamente conocido a nivel mundial, que el devanado del estator de grandes máquinas eléctricas, es la parte con mayor probabilidad de falla y la que incide en mayor lucro cesante. Por lo mencionado anteriormente y consciente de ello, en la inspección visual y basados en los ensayos como también en los históricos de operación, los expertos de OSLINGER S.A.S determinarán la existencia de mecanismos de degradación del aislamiento dieléctrico de los devanados del estator o del rotor debidos a esfuerzos TEAM:
T: Térmico E: Eléctrico A: Ambiental M: Mecánico.
2. SELECTION OF DIAGNOSTIC INDICATORS
3. TO DETERMINE RESIDUAL TIME
Nowadays the technology has not developed to the point of accurately predicting the residual time of a component.
The objective of the expert is to correlate the diagnostic indicators to determine whether the equipment is in good condition (green), regular status (yellow), poor condition (orange) or very poor (red) condition.
The degradation rate is increased from the green state to the red state.

4. DEFINITION OF ACTIONS
With the results of the previous points, considering the importance of the equipment in the production process and reviewing the operating history within its capability curve, the level of intervention to be performed is determined.
When the equipment is between the sections marked with orange and red (intermediate-fast degradation), decisions must be made:
If the equipment is in the orange zone, it is necessary to locate the defect and carry out maintenance.
If your computer is degraded globally, you must plan to replace it.
It is not always possible to purchase spare parts or to intervene the equipment, however, the customer decides to continue operating the equipment, moving it in the risk matrix of the orange zone to the red zone, increasing the probability of failure.
