Synopsis
Explore how explosion-proof motors are tested to prevent fires in mine environments and protect surrounding gas mixtures. This edition presents the core ideas behind protective devices, how heat and flames are managed, and why certain designs work or fail under tough conditions. The material covers the definition of explosion-proof motors, testing procedures, and practical lessons for safer electrical equipment in hazardous settings.
The book explains the two classes of explosion-proof motors and why many tests focus on the second class with relief openings. It outlines how investigators evaluate protective devices, the role of heat dissipation, and how dust and ignition points influence safety. Readers will see how testing conditions are chosen to simulate dangerous scenarios and how results shape safer motor casings and wiring practices.
- Understand how protective devices like gauzes, valves, and baffles are evaluated for cooling flames and limiting temperatures.
- See what factors raise or lower the risk of a puncture or ignition when methane and air mix inside motor casings.
- Learn why certain designs fail under dust, misalignment, or mechanical stress, and how robust construction helps prevent accidents.
- Discover the engineering reasoning behind minimizing open space in casings and improving protection from starting current and wiring.
Ideal for readers of technical safety guides, mining engineering, and electrical equipment design who want practical insight into explosion-prooft motor testing and safer equipment choices.

Évaluation du vendeur 4 sur 5 étoiles
Paperback. Etat : New. Print on Demand. This book investigates the safety of electric motors used in the mining industry by testing their protective devices against explosions caused by methane-air mixtures. The author, who is part of the Bureau of Mines, presents the results of over 200 tests, meticulously detailing the procedures, conditions, and outcomes. The results show that the type of protective device, the motor's operating state, and the presence of coal dust can significantly affect the severity of explosions. The book concludes that the tested protective devices can prevent ignition of the external methane-air mixture effectively when the motor is at rest or running without a fan, highlighting the importance of proper motor operation and maintenance in ensuring safety in hazardous mining environments. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item. N° de réf. du vendeur 9781333884086_0
