Practical Machinery Vibration Analysis and Predictive Maintenance

One of the first points to make regarding vibration due to rolling element bearings is that generally speaking, the bearing is not a source of mechanical trouble but merely a result of other problems. Most often, when symptoms of bearing defects arise, they are accompanied by other symptoms, such as for misalignment, unbalance or lubrication. When dealing with rolling element bearing analysis, a good rule is to not only analyze the symptoms of bearing defects but to also determine why the bearing is defective. Look for symptoms of such sources as unbalance, misalignment, poor assembly, etc. There are many different symptoms of distressed rolling element bearings, and much good information has been published on the subject. It is, therefore, not the purpose of this section to supersede information that is likely already known, but instead to highlight some of its more practical applications and strengthen certain portions. One of the most difficult Bearing problems to identify is incipient failure failure that is just about to happen.

Prevention is a far better goal than trying to solve problems as they arise. While this strategy may be a little costly at first, it is not nearly as expensive as allowing problems to occur. Maintenance problem-solving is primarily concerned with four areas: maintaining critical systems, fixing the problem quickly and faster than the last time, determining what is causing the breakdown to happen so frequently, and identifying the 20 percent of breakdowns that are consuming 80 percent of your resources. This article focuses on the four common types of maintenance problems with the ultimate goal of helping you to prevent or at least minimize each type. A problem is a situation that can be characterized by a gap between your existing circumstances and where you do or do not want to be. The gap cannot be eliminated or maintained through obvious methods. Usually you want to overcome the gap, but sometimes you wish to maintain it.

Practical Solutions to Machinery and Maintenance Vibration Problems

Pratesh Jayaswal, A. Wadhwani, K. The objective of this paper is to present recent developments in the field of machine fault signature analysis with particular regard to vibration analysis. The different types of faults that can be identified from the vibration signature analysis are, for example, gear fault, rolling contact bearing fault, journal bearing fault, flexible coupling faults, and electrical machine fault. It is not the intention of the authors to attempt to provide a detailed coverage of all the faults while detailed consideration is given to the subject of the rolling element bearing fault signature analysis.

Machinery Vibration Analysis and Predictive Maintenance provides a detailed examination of the detection, location and diagnosis of faults in rotating and reciprocating machinery using vibration analysis. The basics and underlying physics of vibration signals are first examined. The acquisition and processing of signals is then reviewed followed by a discussion of machinery fault diagnosis using vibration analysis. Hereafter the important issue of rectifying faults that have been identified using vibration analysis is covered. The book also covers the other techniques of predictive maintenance such as oil and particle analysis, ultrasound and infrared thermography.

I hope you will find this handbook both stimulating and informative as you work to develop and implement RCM-based preventive maintenance programs in Navy ships.

Or we go to our favorite social site and see pictures of our friends, families, and pets. Reactive maintenance or breakdown maintenance as it is referred to as well, does not imply any regular service or tests. If you desire to hilarious books, lots of novels, tale, jokes, and more fictions collections are furthermore.

Vibrations of Power Plant Machines

As vibration isolation and reduction techniques have become an integral part of machine design, the need for accurate measurement and analysis of mechanical vibration has grown. Using accelerometers to convert vibratory motion into an electrical signal, the process of measurement and analysis is ably performed by the versatile abilities of modern electronics. A body is said to vibrate when it describes an oscillating motion about a reference position.
