Preventive Maintenance

The main objective of Preventive Maintenance is to prevent the failure of equipment before it actually occurs.

Preventive maintenance is a schedule of planned maintenance for cost-effective treatments to an existing system that preserves the system, retards future deterioration, and maintains or improves the functional condition of the system.

Goal of the Preventive Maintenance

  • To avoid the consequences of failure of equipment
  • Preventive maintenance is designed to preserve and enhance equipment reliability by replacing worn components before they actually fail

Major Steps in Preventive Maintenance

  • Cleaning
  • Equipment checks
  • Diagnostics activity
  • Partial or complete overhauls at specified periods
  • Lubricating

  • Optimal PM interval using Weibull Distribution

Business Benefits of Preventive Maintenance

  • Reduces the cost of ownership by early interventions and corrective measures before the costly major failures
  • Improved system reliability
  • Decreased cost of replacement
  • Decreased system downtime
