What Students Learn: Preview
Predictive technologies measure one or more characteristics of machine operation, calculate the expected life of the monitored system, and then estimate the condition of equipment and, therefore, the need for maintenance on that equipment. With this information passed along to a good preventive maintenance program, the preventive maintenance team can make informed decisions on task scheduling and make the most of its maintenance and inspection tasks.
Vibration analysis programs are the most commonly conducted PDM efforts. By performing inspection and repairs during downtime, uptime failures of the analyzed components are all but eliminated. PDM is more than vibration analysis, however; multiple technologies, such as infrared thermography, balance, alignment, and electrical signature analysis are part of many PDM programs. Because of these technologies, plants run better and are more competitive. PDM allows maintenance departments to predict when a unit will fail and plan its maintenance during a scheduled downtime, usually when the unit is cooler, cleaner, and not needed for the manufacturing process.
Objectives
When a student completes this study unit, he and she will be able to:

• Define what PDM is and how it can be used in industry.
• Identify the various types of technologies used in PDM.
• Explain what goals should be considered for a new and a maturing PDM program.
• Discuss the scope of basic mechanical PDM.
• Explain how a time waveform and a frequency spectrum can be used to identify machine faults.

What Students Learn: Preview
When a company decides to begin a predictive maintenance (PDM) program, the first technology usually embraced is vibration analysis. Vibration analysis allows the technicians or other specially trained personnel to perform condition monitoring of equipment. Condition monitoring is used at first as a coarse comb to pull out those programs that will imminently cause downtime. Then the program can progress beyond condition monitoring to provide scheduling services for preventive maintenance and identification of redesigns that address repetitive faults.
This study unit will show you the basics of vibration analysis as performed with a data collector and a computer software program. These devices will be used to collect vibration measurement data and to store and display the results.
Objectives
When a student completes this study unit, he and she will be able to:

• Explain how vibration measurements are taken and the systems used to identify measurement points.
• Identify balance, looseness, and misalignment problems.
• Discuss the techniques used to diagnose rolling-element bearing faults.
• Explain how journal bearing condition monitoring and fault analysis is performed.
• Identify speed reducer faults that occur in the gear sets or the internal bearings.
• Describe how resonance can affect the operation of equipment.

Vibration analysis alone cannot perform sufficient condition monitoring to meet the needs of today's industry. Vibration analysis cannot easily find electrical faults, air leaks, electrical discharges, metal particles or contamination and breakdown of lubricants, or other important monitoring processes. Other technologies are needed for these tasks. This study unit will introduce you to these other technologies.
In this study unit, we will investigate many different technologies that can and should often be part of a good predictive maintenance program (PDM). This course is designed to discuss these technologies at a basic level. If you're considering working with one of these technologies, it's very important to understand how to operate the equipment involved and to gain additional equipment training from the manufacturer. These actions will provide you with a safe and profitable expanded PDM program.
Objectives
When a student complete this study unit, he and she will be able to:

• Explain the steps involved in performing balance and alignment on industrial machines.
• Discuss the use and operation of ultrasonic equipment to find problems such as electrical arcing, bearing faults, and internal and external air leaks in pneumatic systems.
• Describe the procedures used in electrical signature analysis (ESA) and how this inspection system can find motor problems.
• Explain how oil analysis can find lubricant problems and contamination.
• Describe how thermography can be used in a PDM environment.
