【摘要】 本文针对发动机燃油过滤器的污染堵塞机理及其防治措施进行了研究,分析了过滤器的一般过滤原理、主要性能参数、和对过滤器精度的选择原则。对过滤器的主要污染物粉尘的参数测定结果进行了分析,为在试验室进行燃油系各种元件的磨损、污染敏感度的试验研究提供可比性和预测的依据,据此提出了燃油系过滤器精度的合理匹配。并通过过滤器的污染特性试验,验证了这种精度匹配的合理性。为了提高油液的净化,减小污染物对元件的磨损,本文分析了两种方法:一是采用旁路过滤系统,通过建立几种油液过滤系统的污染物控制方程,比较得出这一过滤系统的优势;二是采用棉纱作为过滤介质,通过分析棉纱的化学成分从理论上认为它可提高对油液的净化。更多还原

【Abstract】 The paper studyes the filter pollution jam mechanism and the measures of the engine fuel oil system;analyses the common filter principle the main function parameter together with the filter precision selecting principle.In this paper, the paramerer test result of the main contaminants is analysesed.lt puts forward a inferential basis for studying part wear of fuel oil and pollution sensitivity in lab, according to the result, the rational match of the filter precision is raised ,this match is verified by the filter pollution characteristic test. The paper puts forward two ways to advance oil cleaning and reduce part wear.First by building up several pollution control equations of oil filter system. We find that Bypass oil filtration and cleaning system that utilised can get effective result by comparing Second we think that cotton utilised as the filter medium are more effective than tranditional filter by analysising cotton chemistry constituents.更多还原
