煤矿井下防爆发动机尾气排放对比课件

1、柴油机尾气隔爆处理系统FLAMEPROOF DIESEL ENGINE SYSTEMINTRODUCTION简介Diesel Engines are widely used in underground coal operations.柴油发动机广泛地应用于井下煤炭开采。Many mine operators prefer diesel because:-很多的煤矿操作人员喜欢使用柴油机是因为：High Power功率高Not Tethered to a Cable不需要连接电缆High Mobility灵活性高Flexible Use易于使用High Speed速度快Rapid Refuel

2、ling燃料补充快Low initial Purchase Price价格低Typical Diesel Vehicle Use in Australian Underground Coal Mines澳大利亚矿井下使用的通用的柴油车During Longwall Move长壁工作面使用Normal Mine Operation普通煤矿使用VEHICLE TYPE车辆种类Personnel Transporter运人车10-156-105 -10 Tonne LHD5-10吨的牵引车8-134-817- 40 Tonne Shield Hauler17-40吨的支架托运车2-40-1Shear
