Introduction to Maintenance
- Introduction to Maintenance
- Whether a ship at sea, a car in your driveway or an 800 MW electrical generator at a power plant, all equipment is subjected to wear. Sometimes the wear is in the form of corrosion from exposure to chemicals or harsh atmospheric conditions. Sometimes it is due to friction or heat. Continued wear eventually results in failure of the equipment.
Equipment is designed to perform a specific function over a defined time period. Excessive wear reduces the lifespan causing early failures.
Whatever the cause, it is the inspection, repair, and replacement of components, known as maintenance that keeps the equipment running.
Condition Based Maintenance
- Condition-Based Maintenance
- Condition-based Maintenance, or CBM, is the process of measuring and analyzing a parameter that has a direct relationship to the health, or operational, condition of equipment. The goal of CBM is to identify and correct equipment degradation prior to failure. CBM is also known as condition monitoring, or performance monitoring, or Predictive Maintenance, which is abbreviated as PdM.
There are a wide range of predictive technologies that support CBM. The table highlights typical applications for some of the more common predictive maintenance technologies and their applications.
