Types of Equipment Maintenance

There are several types of equipment maintenance strategies, each with its own advantages and disadvantages:

1. Reactive Maintenance

Reactive maintenance, also known as breakdown maintenance, is the "run-to-failure" approach. Equipment is repaired only when it breaks down. While it may seem cost-effective in the short term, it can lead to unexpected downtime, higher repair costs, and potentially dangerous situations. This approach is generally only suitable for non-critical equipment where failure has minimal impact.

2. Preventative Maintenance (PM)

Preventative maintenance involves performing regular inspections, cleaning, lubrication, and component replacements on a scheduled basis, regardless of the equipment's condition. This proactive approach helps to identify and address potential problems before they lead to breakdowns, reducing downtime and extending equipment lifespan. A common example is changing the oil in a car every six months or 10,000 kilometers.

3. Predictive Maintenance (PdM)

Predictive maintenance uses advanced technologies like sensors, data analytics, and machine learning to monitor equipment performance and predict when maintenance is needed. This approach allows for targeted maintenance interventions, minimizing downtime and optimizing maintenance costs. For example, monitoring the vibration of a motor can indicate impending bearing failure. The data informs the repair decision at the appropriate time.

4. Condition-Based Maintenance (CBM)

Condition-based maintenance is similar to predictive maintenance but relies on real-time monitoring of equipment condition to determine when maintenance is required. It involves using sensors and other monitoring devices to track parameters like temperature, vibration, and oil quality, and triggering maintenance actions based on pre-defined thresholds. A large air conditioning system's coolant temperature being monitored. If the temperature exceeds a threshold, an alarm is triggered, and maintenance is scheduled.

5. Reliability-Centered Maintenance (RCM)

Reliability-centered maintenance is a systematic approach to maintenance planning that focuses on identifying and addressing the most critical failure modes of equipment. It involves conducting a failure mode and effects analysis (FMEA) to determine the potential consequences of equipment failures and developing maintenance strategies to mitigate those risks. This approach helps to ensure that maintenance resources are focused on the most important tasks.
