空气滤清器的作用是滤除空气中的灰尘,以减少气缸壁、活塞环、气门等零件的磨损,延长发动机的使用寿命。建筑机械由于经常在含尘量高的恶劣条件下工作,因此,对空气滤清器的选择与使用提出了更高的要求。据有关资料介绍,在发动机发生早期磨损情况下,75%是由灰尘引起的。来自用户的信息反馈,也主要反映空气滤清器选择或使用不当而使发动机出现故障,直至造成主机的长期停机。为此,空气滤清器的 The role of air filter is to filter out the dust in the air to reduce the wear of the cylinder wall, piston rings, valves and other parts to extend the life of the engine. Because construction machinery often works under harsh conditions with high dust content, higher requirements are placed on the selection and use of air cleaners. According to relevant information, 75% of dust is caused by dust in the early wear of the engine. The feedback from the user also mainly reflects that the air filter has been selected or improperly used to cause the engine to fail until it causes the host’s long-term shutdown. To this end, air cleaners
