Mining | These lamps are self-contained units and comprise a strong alloy casing within which are a compressed-air turbine and a small alternating-current generator with stationary windings and revolving field magnets. The air enters the casing at one side, passes through a filter and then through a reducing valve that maintains a constant pressure of 40 psi (276 kPa) on the turbine blades. The air escaping from the turbine is used to scavenge the inside of the lamp and remove any combustible gases that might have entered when the lamp was not in use. It is finally discharged through a series of holes of such a size that the pressure inside the lamp casing is 2 to 3 psi (14 to 21 kPa) above atmospheric. Should this pressure be lost due to the lamp glass being broken, the light is extinguished automatically by a spring-loaded diaphragm, which short-circuits the generator unless held open by the excess pressure. Also called airturbolamp. (references) |
