What is Preventive Maintenance?

In preventive maintenance, regular maintenance work is carried out on plant or machinery. The aim is to identify and eliminate potential problems before they lead to malfunctions or failures. The aim of preventive maintenance is to increase the availability and extend the service life of plant and machinery. Maintenance measures are carried out before malfunctions and failures occur.

How does preventive maintenance work?

  1. Determine maintenance schedules Based on empirical values, manufacturer specifications, etc., a maintenance schedule is drawn up that specifies the planned maintenance of the plant and machinery.

  2. Regular inspections The plant and machinery are inspected regularly to identify potential problems at an early stage.

  3. Maintenance work Based on the maintenance plans and the results of the inspections, maintenance work is carried out. This involves replacing wear parts, for example.

  4. Monitoring the results Once the maintenance work has been completed, the plant and machinery are checked again to ensure that they are functioning properly and that no more problems occur.

What is the difference between preventive and predictive maintenance?

Preventive maintenance and predictive maintenance are both proactive maintenance strategies that aim to minimize asset downtime and reduce maintenance costs. However, there is a fundamental difference between these two strategies.

Predictive maintenance is a data-driven maintenance strategy that uses sensors, for example, to monitor assets in real time and predict when maintenance should be performed. This approach analyzes data on asset performance to identify patterns that indicate potential failures. Predictive maintenance allows maintenance to be scheduled when it is needed, increasing asset life and reducing maintenance costs.

Predictive maintenance is a scheduled maintenance strategy in which regular maintenance is performed whether or not the action is necessary. The goal is to prevent breakdowns by, for example, replacing worn parts, performing routine inspections, and lubricating moving parts. The schedule for preventive maintenance is usually based on the manufacturer's recommendations or on the historical data of the plant.

What are the advantages of preventive maintenance?

  • Reduction of repair costs

  • Predictability of maintenance costs

  • Increased service life of equipment

What are the disadvantages of preventive maintenance?

  • Partly unnecessary maintenance work

  • Higher personnel costs
