A "how-to" reference to help compressed air users and service providers improve the operating efficiencies and reliability of their air compressor and compressed air systems. The manual contains more than 300 pages original text, reference appendices, photos, and performance data.
This book is the record of the conference held in Oxford in 1992 organised by CIRIA, and co-sponsored by the Health and Safety Executive, The British Tunnelling Society and the Medical Research Council's Hyperbaric Sciences Panel. The book consolidates international medical and engineering knowledge and experience on the use of compressed air and hyperbaric techniques, and looks to how they can be safely used in the future.
This book examines the full spectrum of compressor types, how they operate, how to control them, and how operating conditions can significantly impact their performance. Discussed in detail are the influence of pressure, temperature, molecular weight, specific heat ratio, compression ratio, speed, vane position, and volume bottles. The various methods of throughput control are also addressed, including discharge throttling, suction throttling, guide pain positioning, volume, bottles, suction valve unloaders, speed control, as well as how each of these control methods affects compressor life. Compressor surge is defined and discussed in detail, along with the types of instrumentation (controllers, valves, pressure, and temperature transmitters) available, and which of those are most suitable for controlling search. Case studies have been included to illustrate the principles covered in the text. This edition also includes detailed information on compressor seals. Various types of seals providing the best results for different applications are discussed, thereby giving the reader a basic understanding of seals serotypes and applications.
