Reliability And Maintainability Of The Application Of In Jiangling Foundry Equipment Management,

Because facility systems are more and more complex, the requirement for facility performance are higher and higher, there are more and more reliability and maintainability issues. The effect of reliability and maintainability on facility performance makes people recognize gradually the importance of studying reliability and maintainability.The theory of reliability and maintainability are introduced in this paper firstly.Set up the analysis process of facility reliability and maintainability and conducted calculation and analysis for one production line on reliability and maintainability as example. Then according to OEE requirement to set up reliability and maintainability specification. At last, analyses the gap between actual and standard specification. So provided data reference for decision on if facility need update or major repair.Using fault tree analysis to analyses facility failure. Through qualitative analysis, reflect internal relationship, and find out logic relationship between elements, components and system failure, help service people find root cause rapidly and shorten diagnose time, and avoid unnecessary inspection and teardown. Through calculating basic events severity, find out weak area of system, and provide reference for improving system design and implementing actions.Conduct failure analysis by using FMEA methods, and consider the selection of service methods through the aspects of severity, occurrence, and detection. Make clear how many failure modals the facility have, what's the occurrence, what result will be caused after failure happened, and what kind of action should be taken?Finally, applied reliability and maintainability theory on hot melt machine updated program, and improved the usage performance of hot melt machine.
