Mechanical Seal Applications And Troubleshooting

Mechanical Seals, Third Edition is a source of practical information on the design and use of mechanical seals. Topics range from design fundamentals and test rigs to leakage, wear, friction and power, reliability, and special designs. This text is comprised of nine chapters; the first of which gives a general overview of seals, including various types of seals and their applications. Attention then turns to the fundamentals of seal design, with emphasis on six requirements that must be considered: sealing effectiveness, length of life, reliability, power consumption, space requirements, and cost effectiveness. The next chapter is devoted to test rigs used to establish the effect of the various seal parameters on the behavior of face seals. Special test rigs used to establish leakage, wear, friction losses, and temperature distributions for various material combinations, rubbing speeds, pressures, fluid media, and temperatures are highlighted. The following chapters explain primary leakage through the seal gap between the faces of the seals; factors that contribute to seal wear; friction and power of a mechanical seal; relationship of leakage to wear and friction of a balanced face seal; and importance of seal reliability and operating safety. The final chapter explores particularly interesting sealing problems together with the use of special accessories such as heat exchangers; magnetic and cyclone separators; and techniques such as cooling and auxiliary circulation. This book will be useful to mechanical engineers as well as seal designers and seal users.

Maintenance, Reliability and Troubleshooting in ROTATING MACHINERY This broad collection of current rotating machinery topics, written by industry experts, is a must-have for rotating equipment engineers, maintenance personnel, students, and anyone else wanting to stay abreast with current rotating machinery concepts and technology. Rotating machinery represents a broad category of equipment, which includes pumps, compressors, fans, gas turbines, electric motors, internal combustion engines, and other equipment, that are critical to the efficient operation of process facilities around the world. These machines must be designed to move gases and liquids safely, reliably, and in an environmentally friendly manner. To fully understand rotating machinery, owners must be familiar with their associated technologies, such as machine design, lubrication, fluid dynamics, thermodynamics, rotordynamics, vibration analysis, condition monitoring, maintenance practices, reliability theory, and other topics. The goal of the “Advances in Rotating Machinery” book series is to provide industry practitioners a time-savings means of learning about the most up-to-date rotating machinery ideas and best practices. This three-book series will cover industry-relevant topics, such as design assessments, modeling, reliability improvements, maintenance methods and best practices, reliability audits, data collection, data analysis, condition monitoring, and more. Volume one began the series by focusing on design and analysis. Volume two continues the series by covering important machinery reliability concepts and offering practical reliability improvement ideas. Best-in-class production facilities require exceptional machinery reliability performance. In this volume, exceptional machinery reliability is defined as the ability of critical rotating machines to consistently perform as designed, without degradation or failure, until their next scheduled overhaul. Readers will find this volume chock-full of practical ideas they can use to improve the reliability and efficiency of their machinery. Maintenance, Reliability and Troubleshooting in Rotating Machinery covers, among many other topics: General machinery reliablity advice Understanding failure data Design audits and improvement ideas Maintenace best practices Analyzing failures
