Preventive Maintenance Overview

Study Notes

Preventive Maintenance

Main goal is to reduce the likelihood of equipment failure through regular inspections, servicing, and replacements.
Aims to extend the life of machines and improve reliability by preventing unexpected breakdowns.

Planned Maintenance (PM)

Includes scheduled inspections, servicing, and repairs based on time intervals or usage.
Components of PM consist of routine checks, lubrication, adjustments, and parts replacement.
NOT included: Unscheduled repairs or emergency fixes, which fall outside the planned schedule.

Condition Based Maintenance (CBM)

Distinguishes from Planned Maintenance by relying on real-time data and equipment condition.
Focuses on monitoring equipment and performing maintenance only when certain indicators show the need for action.
Aims to optimize maintenance efforts based on actual performance, rather than adhering to a predetermined schedule.

Corrective Maintenance

Occurs when equipment has already failed or is not functioning properly.
Focuses on diagnosing problems and repairing faults to restore equipment to normal operations.
Generally reactive, responding to breakdowns rather than preventing them.

Maintenance Types

Corrective Maintenance is specifically aimed at rectifying faults and restoring equipment to operational conditions.
Other maintenance types include Preventive, Predictive, and Condition Based Maintenance, each with distinct approaches and goals.

Description

Learn about the concept of preventive maintenance, which involves maintaining equipment or systems before any failures occur. Explore the two main subgroups: Planned Maintenance and Conditioned-Based Maintenance, to ensure equipment operates smoothly and to avoid unexpected breakdowns.
