Maintenance engineering encompasses various types of maintenance strategies and practices aimed at ensuring the reliability, availability, and longevity of equipment, machinery, and infrastructure. Here are some common types of maintenance engineering:
1. Preventive Maintenance (PM):
- Preventive maintenance or Scheduled maintenance tasks performed on equipment at predetermined intervals to prevent unexpected failures and prolong equipment life.
- Includes tasks like inspections, lubrication , calibration, and replacement of worn-out parts.
2. Predictive Maintenance (PdM):
- Predictive maintenance Relies on condition monitoring techniques to predict equipment failures before they occur.
- Uses tools like vibration analysis , thermography, oil analysis, and acoustic emissions to detect early signs of deterioration.
3. Corrective Maintenance:
- Reactive maintenance carried out in response to equipment failures.
- Aimed at restoring equipment to its operational state as quickly as possible.
- May involve troubleshooting, repair, and replacement of faulty components.
4. Reliability-centered Maintenance (RCM):
- Focuses on identifying the most critical components and failure modes of a system and developing maintenance strategies based on their risk and consequences.
- Balances the cost of maintenance with the consequences of failure to optimize maintenance efforts.
5. Condition-Based Maintenance (CBM):

- Monitors the condition of equipment in real-time using sensors and other monitoring devices.
- Maintenance actions are triggered based on the actual condition of the equipment rather than predefined schedules.
6. Total Productive Maintenance (TPM):
- Involves the entire organization in maintenance activities to maximize the overall effectiveness of equipment.
- Aims to eliminate losses in productivity due to equipment failures, defects, and downtime.
7. Risk-Based Maintenance (RBM):
- Prioritizes maintenance tasks based on the risk of failure and the potential consequences.
- Considers factors such as safety , environmental impact, and production losses when determining maintenance priorities.
8. Proactive Maintenance:
- Focuses on identifying and addressing potential issues before they lead to equipment failures.
- Includes activities like root cause analysis , design improvements, and reliability testing.
9. Run to Failure (RTF) Maintenance:
- Involves intentionally not performing maintenance on equipment and allowing it to run until it fails.
- Typically used for non-critical equipment where the cost of repair or replacement is lower than the cost of preventive maintenance.

1 个月Hi, I pretend to put this in perspective. I saw the picture at the beginning of this article, and I was quite surprised. Writing about maintenance and other practices or specialities is wonderful; however, with all respect, I believe we need to give structure to our knowledge. Some meaning of words.? There is a mixed up the type of maintenance with methodologies, and priorities and criticality.? Each one has a specific ending as part of processes in the maintenance management.? This kind of stuffs create more confusion than help.?
