Costly oversights occur repeatedly despite thoughtful planning dedicated to maximizing the operation and lifespan of the motor. One unsettling realization is that testing, considered part and parcel of preventive maintenance, is not preventing anything because there is nothing to indicate that analyzing the data was even considered. This is a major pitfall and a classic example of a gap in a company’s motor management program.
Using the same concept of a trifecta (three factors for success), this article provides companies with the winning strategies of motor maintenance, focusing on the three reliability tasks for electric motor testing and the order in which they should be applied. Following these steps will drastically improve their odds in motor reliability and put a big payday at the end of their production goals.
Condition Monitoring when used to drive reliability improvement offers diagnostics, information and data for Root Cause Analysis and equipment redesign, along with verification of defect or design correction. Condition monitoring applied proactively is a context embracing world class reliability maintenance concepts.
In this paper I will outline some of the key business opportunities and issues which are driving change in the industry, summarize some of the resulting trends, as I see them, and then draw some conclusions regarding the implications of these trends for Condition Monitoring equipment manufacturers and suppliers, Condition Monitoring contractors, and organizations employing Condition Monitoring techniques.
It may seem that visual inspection goes beyond what thermographers are hired to do, but conscientious thermographers include notes and even images in their reports when they see code violations, broken equipment, incorrectly sized fuses, bad wiring, etc. A good thermographer will not ignore copper tubing used as a fuse, even if it looks fine in the infrared. Whether the inspection is insurance driven or a proactive stance, an infrared inspection and a visual inspection complement each other.
Continuous monitoring of the filter elements in a hydraulic system can provide valuable clues to the performance of the filter and the condition of the system. Before I discuss this, let’s consider some of the advantages and disadvantages of common filter locations in a hydraulic system.
When equipment fails, wind farms must deal with exorbitant crane mobilization expenses, lost energy production, soaring costs per kilowatt-hour and untimely delays in obtaining replacement parts in a burgeoning industry where the demand for necessary components routinely outstrips supply.
A Novel Approach in Process Monitoring and Proactive Maintenance: MCM and its Applications in Foundry Industry
MCM has many successful applications in different areas of industry. In this section, three applications of MCM in foundry industry will be presented.
Infrared Thermal Imaging is an excellent condition monitoring tool to assist in the reduction of maintenance costs on mechanical equipment. The technique allows for the monitoring of temperatures and thermal patterns while the equipment is online and running under full load. Most mechanical equipment has allowable operating temperature limits that can be used as guidelines. Unlike many other test methods, Infrared Thermal Imaging can be used on a wide variety of equipment including pumps, motors, bearings, pulleys, fans, drives, conveyors etc.
