本文就我厂生产的工程机械柴油机所匹配之排气消声器存在的质量问题进行了分析,提出了改进意见和方法,并通过试验验证。排气消声器作为工程机械柴油机的重要零部件之一,其与柴油机匹配的好坏,将直接影响到柴油机性能的发挥。现阶段市场上的排气消声器配套厂家众多,但材料多为普通钢板焊接而成,内部结构也不尽合理;导致消音器产品普遍存在消耗功率大,排气背压高,整机油耗高,消声效果差,易生锈等问题,尤其是在工程机械配套领域,情况更为严重,亟待优化提升。
This article analyzes the quality problems existing in the exhaust muffler matched with the construction machinery diesel engines produced by our factory, and puts forward the suggestions and methods for improvement, and passes the test. Exhaust muffler as one of the important components of construction machinery diesel engine, its match with the diesel engine quality will directly affect the performance of diesel engine. Exhaust muffler on the market at this stage a large number of supporting manufacturers, but most of the materials for the ordinary steel welded together, the internal structure is not always reasonable; resulting silencer products widespread consumption of power, exhaust back pressure, high fuel consumption, Muffler effect is poor, easy to rust and other issues, especially in the construction machinery supporting areas, the situation is more serious and urgent need to optimize and enhance.
