Abstract：Monitoring and maintenance of running status of electrical and mechanical equipment is a crucial link for ensuring stable operation of a coal preparation plant.The problems faced by Caojiatan Plant involve,among others,differences in technical competence and skill levels of maintenance personal,inadequate and unsound equipment lubrication and monitoring work,and overload of equipment.As a remedial measures,an intelligent temperature and vibration monitoring is applied.The system is comprised of three parts:wireless data collector,data collection terminal and equipment fault diagnostic platform,which is capable of executing remote monitor-ing and diagnosis as well as early-warning of failure of equipment.Field application shows the use of the sys-tem can effectively guide lubrication work,improve management level and reduce fault removal and mainten-ance costs of equipment;each year,the number of equipment repaired or replaced is reduced from 31 to 23 while that discarded is cut by 2,resulting in a save of cost of about one million yuan a year;in 2023,the overall equip-ment breakdown time was seen to be reduced because of realization of intelligent monitoring and improvement of operation efficiency of core equipment;and especially in the third and fourth quarters of 2023,through optim-ization of algorithmic model,the equipment breakdown time was further reduced by an average of 60.98%com-pared with the corresponding period in the previous year.The use of the system for real-time monitoring and prevention of fault of electrical and mechanical equipment has led to reduced failure risks and improved man-agement level of equipment,and the building of a high-efficiency equipment operation system,thus effectively enabling the Caojiatan Plant to operate in a safe,steady and highly efficient manner.
