机油泵失效模式的研究

Study of the Oil Pump Failure Modes

本文结合工厂机油泵失效模式的研究项目,较为透彻完整地阐述了工厂设计部门和工程部门在机油泵失效模式中应用PFMEA和FTA手法的基本方法,阐明了通过FTA分析和掌握机油泵关键零件—弹簧及其组件失效模式之间的逻辑关系,进而通过PFMEA手法以重要度区分的形式找到优先解决机油泵质量隐患的次序。同时论述了PFMEA和FTA之间的密切联系和解决质量事故的优化分析方法。通过具体案例分析,证明FMEA和FTA方法解决质量问题效果显著,对指导同类产品设计具有指导意义。

Combining with the factory machine oil failure modes are thoroughly complete research project,describes the design department and engineering departments factory in oil pump failure mode and application of PFMEA basic methods,techniques of FTA clarified through the FTA analysis and master machine oil key parts-spring and its components failure modes,and the logical relationship between the PFMEA technique to important degrees by the form of priorities for the distinction find oil pump hidden sequence.Quality Meanwhile,the author discusses the PFMEA and close contact between FTA and solve quality accident optimization analysis method.Through the specific case analysis,proof FMEA and FTA method to solve quality problem for guiding effect significantly,has guiding significance for similar product design.
