一种新型压差管密封连接结构的颗粒捕集器总成
本技术属于汽车排气净化
,具体涉及一种新型压差管密封连接结构的颗粒捕集器总成。
技术介绍
颗粒捕集器即DPF,是一种安装在柴油发动机排放系统中的过滤器,使用过程中由于劣质燃油等原因易导致DPF堵塞失效,不但无法过滤尾气,还使油耗增加,发动机性能恶化,甚至损毁发动机,所以需要时时监测DPF的过滤组件两侧的压力,发现堵塞及时进行清洗或更换;过滤组件两侧设置的压差管是监测压力的通道,保持压差管与DPF之间气流畅通是保证监测结果准确性的关键,在长期的工作实践中发现,由于压差管与DPF是焊接密封的,其焊缝处易发生堵塞,导致监测结果不准确,而且难以进行清理,故研发本方案。
