防爆柴油机国三排放试验台的设计研究

Design and Research of National Third Emission Test Bed for Explosion-Proof Diesel Engine

由于煤矿井下的恶劣环境直接影响矿工的生命健康,而井下污染物的一个重要来源是防爆柴油机作为动力的无轨胶轮车尾气排放,随着国家煤监局要求井下防爆柴油机排放必须达到国三标准,因此需建设一套防爆柴油机排放试验台对井下防爆柴油机进行国三排放检验。采用测控加载系统、进气流量及压力测量系统、数据采集分析系统及排放测试系统搭建了防爆柴油机国三排放试验台,结果表明该试验台运行平稳、可靠。

Because the harsh environment in the coal mine directly affects the life and health of miners,and an important source of underground pollutants is the tail gas emission of trackless rubber tyred vehicles powered by explosion-proof diesel engines,with the requirements of the state coal regulatory bureau that the emission of underground explosion-proof diesel engines must meet the national third standard,it is necessary to build a set of explosion-proof diesel engine emission test bed to carry out the national third emission inspection of underground explosion-proof diesel engines through the measurement and control loading system.The national third emission test bed of explosion-proof diesel engine was built with the intake flow and pressure measurement system,data acquisition and analysis system and emission test system.The results show that the test bed is stable and reliable.
