Fire Pump Handbook

   NFPA 25 was first released in 1992 with the declared purpose being the promote the activities and certain sections were specifically pertaining to fire pumps. NFPA fully recognizes that the installation standards such as NFPA 20 or maintenance document such as NFPA 25 must be suitable for enforcement and, as a result, must be concise and without explanatory text. Additionally, it must be acknowledged that such standards cannot be written to cover every situation that could be encountered. Therefore, NFPA 20 and NFPA 25 must be applied with judgment, the application of good sense, and an awareness of the rationale for the requirements. To assist in this task, NFPA, in partnership with the NFSA, has developed the Fire Pump Handbook. The present publication is intended to provide users of NFPA 20 and applicable portions of NFPA 25 with background information on certain requirements. The book also contains some suggestions on how certain provisions of the standards can be implemented effectively. The contents of the handbook are intended to provide users of NFPA 20 and NFPA 25 with a better understanding and appreciation of the documents. However, the reader is cautioned to look upon the commentary and other supporting information as views of the editors and contributing authors. Only the contents of NFPA 20 and NFPA 25 are considered the official position of NFPA.

Testing and Balancing HVAC Air and Water Systems

   This content of the present volume is mainly based on the field and teaching experience of the author in testing of the various types of HVAC systems, their balancing, design and evaluation. There are two basic methods of balancing. One method is balancing from the terminals back to the fan or pump. This method is proportional balancing. It was during a job at a nuclear power plant many years ago that I first started using the proportional method that I have outlined in this text. As we could not get enough experienced balancing technicians for the project, I began instructing sheet metal mechanics with little or no balancing background in proportional balancing. I found that the proportional method was quickly learned in a classroom setting and then applied to the field. The proportional method follows a scientific approach with quite predictable results, it also establishes a starting point and allows others with proportional balancing experience to take over the balancing when there is a need for that, large systems are balanced quicker, and the least resistance is imposed on the system while delivering air or water to the terminals at design or at the highest possible flow quantities... The author has continued to teach the presented method in his classes, seminars and in-house training programs and now with the СТАВ program with great success...

Machinery Condition Monitoring Principles and Practices

   While teaching the subject of machinery fault diagnostics and signal processing, and conducting short courses for industry professionals for more than fifteen years to the senior year and graduate students at the Indian Institute of Technology, Kharagpur, I have always had a problem locating a single book on the subject. Though there are excellent research journals and trade magazines on the subject, I have failed to locate a book without bias toward the equipment used or process followed for detecting faults in machines in general, and rotating machines in particular. With this preamble I began to write this book, drawing on my experience with machinery condition monitoring while consulting for many industries in India and abroad over the last two decades. In many of my fault-detection exercises in the industries where I have consulted, I have come across technicians and engineers who wonder what fast Fourier transform (FFT) is, and I have been provided with a table full of numbers and asked to find the fault in the machines. Many engineers in the field learn this subject from the technical brochure of the equipment they use, without understanding their limitations. They feel that since they have a piece of costly equipment at their disposal, they can detect and diagnose the fault in any machine. One of the purposes of this book is to eliminate such myths. No offense intended...

Detection of Electrical Discharges in Bearings

   This is a very informative and officially released publication specifically addressing the VFDs, standing for the "variable frequency drive"s; and the volume was prepared by the recognized specialists of the world-known SKF Company. The use of subject drives is constantly increasing, and that is mostly because of their cost effectiveness. The makers of these drives have all significantly and so valuably contributed to the above mentioned development by making subject equipment much better and reasonably affordable, and this was done by introducing the PWM - standing for the pulse width modulated - drives. However, it should of course be understood that, along with this newly introduced technology, some more premature bearing technical failures occurred; moreover, increasing number of electric motors fail prematurely. The main declared reason of these premature failures in the mentioned electric motors was electrical erosion. Dismounted bearing will be showing evidence of the electrical erosion - for example, the grease of the motor is also affected same way the other bearing components are. One of the proposed ways to diagnose the electrical erosion implies using the oscilloscope with a contact probe on a rotating shaft, however bear in mind that this way is considered expensive and too time-consuming, thus very impractical...
