Since the development of machinery, there has been a war against friction. Friction causes machinery to vibrate excessively, sound louder, use more energy to do a given job, and, most importantly, wear out faster. To counter friction, lubricants have been developed.

Lubricants were once basic animal fats and plant oils used on simple machines. Today's lubricants are chemical compositions specially designed for specific types of machines and their work environment. There are now hundreds of types of oils and grease to select from, each tailored specifically for the machine or an individual component of any given machine.

This study unit is designed to give students the information they need to understand how lubricants are blended into these very special compounds and how they are selected for various applications.

Lubricating equipment is one of the most important industrial maintenance activities performed. Lubricants reduce friction, which saves on energy costs. They reduce wear, which saves on equipment maintenance costs. Proper lubrication significantly reduces machine downtime resulting from broken or worn out components. In addition, proper lubricating practices help keep a machine in tolerance for a longer period of time.

In today's world of twenty-four-hour-a-day, seven-days-a-week, plant operation, the role of lubrication takes on even greater importance. Equipment must be lubricated on a timely schedule, in the proper amounts, and with the correct lubricants to sustain long work cycles between planned shutdowns. This study unit will show you how to properly apply lubrication and maintain lubrication systems.

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.

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.

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.
