Maintenance Practices
Breakdown maintenance
You fix the machine when it breaks.
- Downtime is common
- Secondary damages are COSTLY
- Control is lost over production
Preventive maintenance
You perform regular overhauls based on a scheduled time so that the machine will not fail.
- less costly than breakdown maintenance
- Repair intervention is based on time
- Many times you fall into the breakdown maintenance because you are basing your practices on time and not on operating conditions of the machine.
Predictive maintenance
You don’t fix it if it will not breakdown.
- Much cheaper than Preventive Maintenance
- Repair intervention is based on operating conditions
- This is the only way to look into the future since machines express their pain before failing. Their problems have symptoms. Many technologies help us interpret these symptoms to understand their causes. We can rely on: Vibration analysis, Oil analysis, Thermal imaging, Motor current analysis, Ultrasound
Proactive maintenance
You need to anticipate and solve the problems even before they occur.
- THIS IS THE ONLY WAY TO EXTEND THE LIFETIME OF THE MACHINE
- After checking symptoms using predictive maintenance, we perform root cause analysis to treat and solve the cause.
- Experts should go through details like the following few points: o Purchase specifications o Installation procedure, levelling, precision alignment, … o Acceptance testing o Routine maintenance procedure, tools,… o Condition monitoring technologies
- LOWEST COST AMONG ALL MAINTENANCE STRATEGIES
