[Abstract]:In recent years, with the development of large scale, automation and high efficiency of handling equipment in coal terminal, the maintenance and management problem of loading and unloading equipment is becoming more and more prominent.The equipment of coal wharf has many kinds, complex composition, strong randomness of fault, various modes, and different influence on the reliability of equipment, which leads to the complication of maintenance management of equipment.Based on reliability theory and equipment fault risk assessment method, this paper deeply studies the maintenance decision of key equipment in silo coal wharf. The main contents are as follows:Firstly, the equipment composition and fault analysis method of silo coal wharf are studied.The traditional and silo coal wharf loading and unloading technology are analyzed. On the basis of the working principle of the key equipment of the silo coal wharf, the structure composition of the loader, the dumper and the belt conveyor are analyzed in detail.Based on failure mode and impact analysis, this paper studies the FMEA analysis method and flow chart of key equipment of silo coal wharf based on failure Modeand Effects analysis and equipment characteristics of silo coal wharf.Secondly, based on the principle of FMEA, the reliability of the key equipment of silo coal wharf is analyzed.Based on the widely collected fault data and the structure composition of the key equipment, the functions of the equipment mechanism, common faults and their influences are analyzed, the cumulative failure rate of the equipment is calculated, and the failure rate index is graded.Based on the basic principle of FMEA analysis, the characteristics of flow and equipment fault are analyzed, the severity and detection degree of equipment fault mode are comprehensively graded, and the loading machine, overturning machine and belt belt machine are analyzed by FMEA.Thirdly, based on the fuzzy theory and the ranking method to approximate the ideal solution, the fault modes of loading and overturning are evaluated.The index system of the key equipment of silo coal wharf is established. The fuzzy number and information entropy are applied to the fuzzification and weighting of the index value. Based on the approach ideal solution decision method, the comprehensive evaluation index is studied.The risk assessment of the fault mode of the stowing mechanism and the overturning system of the ship loader is completed.Finally, according to the reliability analysis and risk assessment results of silo coal wharf equipment, maintenance decision is made.Based on the maintenance theory of reliability Centered (reliability Centered), a RCM maintenance decision model for key equipment of coal wharf is established. Based on RCM logic decision process, the decision standard for maintenance mode of coal wharf equipment is established.The failure mode of the loading machine and the turn-over system is made to make the decision of the maintenance mode.The commonly used preventive maintenance cycle determination method is given. According to the actual operation data, the preventive maintenance cycle is calculated for the cracking failure mode of the bottom beam of the dumper.Based on the above research work, this paper puts forward the maintenance decision of key equipment of coal wharf based on reliability and risk assessment, which provides a new idea for the maintenance decision of key equipment of coal wharf in the future.
