1.空气滤清器作用空气滤清器是发动机进气系统的重要部件,其作用是分离出空气中的灰尘,减轻汽缸、活塞、活塞环等零部件磨损。空气滤清器保养不当,会造成发动机进气量不足、燃烧不充分、功率下降、冒黑烟、加快汽缸磨损,导致发动机动力性能、经济性能和环保性能下降。因此,空气滤清器的正确维护保养对保证发动机稳定可靠运行具有重要意义。2.干式空气滤清器结构目前挖掘机柴油发动机常用的空气滤清器分为惯性式、过滤式和综合式3种,根据滤芯材料又可分为干式和湿式2种。湿式空气滤清器因
1. The role of air filter Air filter is the engine air intake system is an important component, its role is to separate the dust in the air, reducing cylinder, piston, piston ring and other parts wear and tear. Improper maintenance of the air filter will result in insufficient intake air, insufficient combustion, power loss, black smoke and accelerated cylinder wear resulting in reduced engine power performance, economic performance and environmental performance. Therefore, the correct maintenance of the air filter to ensure stable and reliable operation of the engine is of great significance. 2. Dry air filter structure At present, the excavator diesel engine commonly used air filter is divided into inertial, filter and integrated 3, according to the filter material can be divided into two kinds of dry and wet. Wet air filter due to
