摘　　要：防爆柴油机的进排气系统是防爆改造的关键部分,进气防爆栅栏的有效进气面积直接关系到防爆柴油机动力指标和燃烧性能。通过对防爆柴油机进气需求进行分析,根据收缩系数确定防爆进气栅栏的实际进气面积,并进行实例计算和流场分析,可为进气栅栏的设计改进提供理论依据。The intake and exhaust system of explosion-proof diesel engine is the key part of explosion-proof transformation.The effective intake area of intake explosion-proof fence is directly related to the power index and combustion performance of explosion-proof diesel engine.Through the analysis of intake demand of explosion-proof diesel engine,the actual intake area of explosion-proof air intake fence was determined according to the contraction coefficient.The calculation of an example and the flow field analysis could provide a theoretical basis for the design and improvement of the intake fence.
