Optimization of air brake system using rotary compressor in Locomotives

Abstract
Air brake system comprises the brake system using compressed air. For getting the pressurized air we use the compressor. Air brake system is used to stop the running train locomotive which contain high amount of kinetic energy. The pressurized air is provided by the different types of air compressors as per the requirement. The air brake system is used in present railway locomotives use the reciprocating compressor to provide the pressurized air to air brake system. The air pressurized by two compressors they are reciprocating and rotary compressors. There is a drawback in reciprocating compressor there is continuous contact of piston and cylinder. This introduces a significant amount of friction, which takes more power input to overcome this. Due to upward and downward movement, there are more chances of jerk on the coaches. Reciprocating compressors more expensive and require more maintenance. To overcome these drawbacks of reciprocating compressors, this can be replaced by rotary compressors. Rotary compressors use impellers (rotating part of compressor). . So maintenance cost can be saved. Due to continuous rotation of impeller, jerk on coatches will be controlled. Whereas rotary compressors are energy efficient with higher EER(energy efficiency ratio). In this way we can optimize the function of air brake system using rotary compressor.
