Design of Rotating Equipment Preventive Maintenance System Based on the Plant Information System

For the convenience of plant equipments maintenance,this paper designed a rotating equipment to preventive maintenance system which can calculate equipment prediction reliability and alarm automatically.It can help for making maintenance plan.The rotating equipment preventive maintenance system retrieves rotating equipments running time data from plant information system(PI)and then calculates MTBF,if the equipment run time reaches or exceeds the preset limit,the equipment will be alarmed for maintenance.After factory practice,it's proved that the system improves the maintenance work efficiency obviously.
