Predictive Maintenance is the use of various types of sensors to predict wear and potential damage to equipment in order to anticipate and determine if the equipment is operating properly and needs maintenance.
Predictive maintenance is a more advanced form of maintenance than preventive maintenance (PM). It is in the equipment monitoring technology on the basis of a new equipment maintenance method, with ? Preventive maintenance? Compared to its differences and advantages as shown in Table 5-1.?
Project preventive maintenance predictive maintenance?
Analysis method according to the equipment repair history, estimated parts use period according to the instrumentation instructions, a comprehensive evaluation of the equipment, drawing parts of the standard operating curve?
Anomalous phenomena measurement method of regular inspection, visual inspection of the condition of the parts concerned, the occurrence of failure rarely alarm with the instrumentation in the operation of the equipment for continuous monitoring, can be measured at an early stage of impending failure, failure before the occurrence of an alarm signal?
Maintenance costs parts replacement of a large number of large costs, but do not have to purchase monitoring instrumentation only on the bad parts are replaced, less expensive, but to purchase automatic monitoring instrumentation, more investment, generally in the case of chemical installations, automated assembly lines, large-scale equipment, etc. to install
