Predictive Maintenance (PdM) techniques help determine the condition of "In-Service" equipment in order to predict when maintenance should be performed. This approach offers cost savings over routine or time-based preventive maintenance because tasks are performed only when necessary.
PdM or "Condition Based" maintenance attempts to evaluate the condition of equipment by performing periodic or continuous equipment monitoring. The primary goal of PdM is to perform maintenance at a scheduled point in time when the maintenance activity is most cost effective and prior to the equipment failure in service. The "predictive" component of the term Predictive Maintenance stems from the goal of predicting the future trend of the equipment's condition. This approach uses principles of statistical process control to determine at what point in the future maintenance activities will be appropriate.
Most PdM inspections are performed while equipment is in service, thereby minimizing production disruption of normal system operations. Adoption of PdM in the maintenance of equipment can result in substantial cost savings and higher system reliability. It is a systematic approach to defining a routine maintenance program composed of cost-effective tasks that preserve important functions. The result is a maintenance program that focuses scarce economic resources on those items that would cause the most disruption if they were to fail. Hence, a return-on-investment (ROI) for each maintenance dollar spent on any given PM Program is expected.
Predictive maintenance (PdM) techniques in addition to traditional preventive measures. PM Program management responsibilities can vary. For instance, routine testing and monitoring of manufacturing rotating equipment program management responsibilities include the responsibilities for data collection program:
Emission Spectroscopy (Elemental or Spectro-chemical Analysis)
Infrared Spectroscopy (FT-IR)
Moisture Oxidation Nitration
Sulfates Solvents Insolubles
- Ferrography (Wear Particle Analysis)
- Filter Analysis
- Write new lubricant specifications
- Vibration Analysis
- Thermography (corona detection)
- Ultra Sonics (Leak Detection or acoustic)
To-day, oil analysis programs utilize modern technology and laboratory instruments to determine equipment condition and lubricant serviceability. Contact REAL Services and have us help you customize PdM Program for you, your company and investors; Making your PM Program mean "Profit Making"™.
