Описание: This book discusses condition based monitoring of rotating machines using intelligent adaptive systems. The adaptive fault diagnostics systems presented can be used in multiple time and safety critical applications in domains such as aerospace, automotive, deep earth and deep water exploration, and energy.
Описание: The first part of Screw Compressors gives a review of recent developments in screw compressor design. The second part presents a generalized mathematical definition of screw machine rotors and describes some well known lobe shapes in detail. The third part treats the mathematical modelling of the thermodynamics and fluid mechanics of compression and expansion processes. This includes discussion of the issues addressed in order to be able to predict the optimum rotor size and speed and built-in volume ratio and, in the case of oil flooded machines, the injection position and jet diameter. The fourth and fifth parts discuss the principles used and describe the application of the analytical procedures and rotor profiling techniques, presented in the earlier chapters, to the design of a number of twin screw compressors, currently manufactured including the examples of combining expansion and compression in the same machine.
Описание: This book - the authors' second book on screw compressors – presents the results of the most up to date methods of three-dimensional modeling of the fluid dymanics and the solid-fluid interaction within these machines, which are still being developed. By including them in the design process, it is possible, not only to predict flow patterns more accurately, and hence improve the design of the critical components, but also to determine how the pressure and temperature distribution within the compressor distorts the rotors and casing and how this, in turn, has an interactive effect on the performance.Such calculating facilities are especially valuable for oil free machines, in which temperature changes are much larger and thus make thermal distortion effects more significant. However, it confers advantages in all cases, as improved machine tools enable manufacturing tolerances to be reduced and hence compressors can be built with smaller clearances. Four examples outline the scope of the applied mathematical model for three dimensional calculation of fluid flow and stresses in the solid parts of the screw machine.

Описание: This book provides a summary of the essential knowledge and working processes involved with control of rotating equipment including: * machine characteristics; * overall control strategies; * detailed design; and * best practices. Emphasis is placed on the role of pumps and compressors as part of the overall process flow rather than treating them in isolation as this tends to optimize energy efficiency. Readers are made aware of the critical roles of rotating equipment and are given a good understanding of their dynamic behaviors, including surge/choke. The author imparts the practical know-how and skills involved in the design and implementation of capacity and anti-surge control and safe-guarding logic. Furthermore, the book discusses real-time monitoring of solutions based on operational requirements, dynamic models for control of supply and demand, cause-and-effect relationships, the use of online and offline data, and collaboration with other engineering disciplines. The text facilitates support for the day-to-day operation of in-house open-platform compressor control applications, encouraging the growth of analytic skills in troubleshooting and fixing common problems; it also inculcates a basic understanding of the principles of third-party proprietary technologies and supports decision-making between in-house and third-party solutions. Process engineers working in the oil-and-gas, refining, petrochemical, and chemical industries who bear responsibility for designing control solutions involving pumps and compressors will find this book an invaluable source of practical advice. This book also helps engineers working on design and maintenance of rotating equipment to understand the perspectives and requirements of process control.
