Description
Technical field
The present invention relates to the fields such as chemical industry, metallurgy, manufacture, particularly relate to a kind of initiative preventative maintenance method, device for dynamic equipment.
Background technology
Dynamic equipment refers to the rotating machinery (that is having the equipment of energy resource consumption) that driving machine drives, and as pump, compressor, blower fan, packaging machine, stirring machine etc., its energy can be electric power, aerodynamic force, steam power etc.
Fig. 1 shows of the prior art monitoring dynamic equipment running status and the schematic diagram of Breakdown Maintenance.The a large amount of dynamic equipment comprised in the process units of current China major part chemical industry, metallurgy, manufacturing is monitored its running status by means of only distributed discrete control system (DCS), programmable logic control system (PLC), data acquisition and supervisor control (SCADA) etc., when equipment dynamic in normal productive process is out of service, trigger alarm signals notifies that related personnel takes to safeguard or switching measure.Because dynamic equipment all carries very important effect in the production run of industry-by-industry, such as: the stirring in transferring raw material or product, course of reaction, maintain the energy equilibrium etc. of process units, this classic method of carrying out safeguarding after dynamic equipment breaks down again cannot meet the service requirement of process units " peace, steady, long, full, excellent ", even threatens the life security of field personnel.
Summary of the invention
Based on the defect that prior art exists, need to provide a kind of real time and on line monitoring and evaluation method, based on real-time data base, initiative preventative maintenance is carried out to dynamic equipment, by the risk factor of monitor and forecast fault, make the factor that the fault symptom of a trend does not produce, prevent to reach the object occurring and develop that lost efficacy, and then extend the serviceable life of machine, significantly save maintenance cost.
The object of this invention is to provide a kind of method can carrying out initiative preventative maintenance online to the dynamic equipment in process units, and a kind of a kind of initiative preventative maintenance device for dynamic equipment that guidance can be provided the maintenance of dynamic equipment or switching.
For solving the problems of the technologies described above, as first aspect of the present invention, providing a kind of initiative preventative maintenance method for dynamic equipment, comprising the following steps:
Real-time Obtaining moves the running status of equipment;
Timing also calculates the working time of dynamic equipment;
