摘　　要：防爆柴油机进气栅栏是一种能够熄灭内燃机可燃气体的安全装置,会带来较大的进气阻力使得进气量减少,从而引起许多燃烧、排放等问题。为了解决这一问题,对进气栅栏的结构进行分析,选取进气栅栏的进气管长度、稳压腔角度以及栅栏缝隙间距这3个比较重要的因素,每个因素选取3个水平进行正交试验分析,得出各因素对进气量影响的主次顺序,最终确定进气栅栏最佳的结构匹配方案。The intake fence of flame proof diesel engine is a kind of safety devices which extinguishing combustible gas of internal combustion engine, it brings more about air intake resistance leading to air inflow reduced, and results in a lot of problems such as combustion and emissions. To solve this problem, the thesis selected three important factors what the intake pipe length, pressure stabilization cavity angle and fence intervals distance, and each factor selects three levels to orthogonal test analysis. It works out that each factor the order of affect air inflow, finally we ascertain the best matching scheme about intake fence structure.
