以装载机三包反馈故障为对象,分析了液压元件故障模式及产生的主要原因,提出了液压系统各元件的混合污染是造成该系统质量事故、三包费用居高不下的根源,并据此提出了对液压系统污染进行综合控制的措施,在分析有关标准和对液压元件制造现状广泛调研的基础上制定了切实可行的液压元件清洁度分步实施控制指标和规范,针对产品液压系统特点制定了用油指标,这些控制措施的实施有效地提高了产品液压系统的可靠性,收到了明显成效。
This paper analyzes the failure modes of hydraulic components and the main causes of them, and puts forward that the mixed pollution of hydraulic components is the root cause of the high quality of the system and the high cost of the Third Warrant. Based on this, Proposed a comprehensive control of hydraulic system pollution measures, based on the analysis of the relevant standards and extensive research on the status of the manufacture of hydraulic components based on the development of a feasible hydraulic components clean step by step implementation of control indicators and specifications for the product of the hydraulic system characteristics of the development The oil indicators, the implementation of these control measures effectively improve the reliability of the product hydraulic system, has received significant results.
