基于故障模式的液压过滤器设计分析

Design and Analysis of Hydraulic Filter with Failure Mode

根据国内外的相关统计数据,液压系统中大约有70%的故障是由于系统介质受到污染所引起的^([1])。针对控制液压系统污染度的重要辅件-过滤器,收集总结过滤器使用的各种经验与教训,在刚开始设计时即着手分析危害性及其造成的影响,挖掘出过滤器潜在的缺陷,从而在过滤器的设计阶段采取改进和预防措施,达到消除过滤器可能发生故障的原因,增强了过滤器的设计有效性,降低了过滤器发生故障的风险。通过该文的阐述分析,为液压过滤器的改进提供了解决方案,对其他液压系统元件也起到借鉴作用。

According to the statistics at home and abroad,about 70%of the faults of hydraulic system are caused by medium pollution^([1]).In the light of the filter,which being as the important component of controlling the pollution degree of hydraulic system,we collect and summarize experience and lesson of field use.In the early stage of design,we start from the impact and hazard analysis,find out the possible potential defects of the filter,and take effective preventive measures in time in the design stage,so as to improve the design efficiency,eliminate the potential risks and eliminate the possible failure factors.Through the elaboration and analysis of this paper,it provides a solution for the improvement of the hydraulic filter,and also plays a reference role for other hydraulic system components.
