Design of predictive maintenance system of coal cleaning and processing equipments

Common faults and its causes of several main coal cleaning and processing equipments were analyzed. In view of problem that maintenance mode of current coal cleaning and processing equipment cannot accurately and effectively identify early fault and potential threat, a predictive maintenance system of coal cleaning and processing equipments was designed. The system is mainly composed of function module of basic information management, function module of real-time monitoring of equipment condition, function module of fault simulation, function module of predictive maintenance and decision, four modules are complement with each other and coordinates effect, which can evaluate running status of current equipment, and forecast development trend of fault, so as to realize the predictive maintenance and health diagnosis of the equipments.
