Abstract

PROBLEM TO BE SOLVED: To obtain the optimum maintenance/inspection period of a facility unit based on the actual result of maintenance/inspection and to reduce maintenance/ inspection cost by extending the maintenance/inspection period, when abnormality is not detected at the time of maintenance/inspection, returning it to the preceding maintenance/inspection period by one when abnormality is detected and setting the maintenance/inspection period at the time to be the optimum one. SOLUTION: A recommendation inspection period (t) that a maker designates is set previously to a facility unit. First maintenance/inspection is executed after the period (t), in accordance with the recommendation/inspection period after the facility unit is installed. When abnormality is not detected in the facility unit, a designated day α is added to (t), and the new maintenance/inspection period is set to t+α. When abnormality is not detected even in a second maintenance/inspection, the maintenance/ inspection period becomes t+2α. When abnormality is detected at a third maintenance/ inspection, the maintenance/inspection period is set back to one previous, and the new maintenance/inspection period is set to t+α. Thus, the maintenance/inspection period is set optimal for the facility unit.

Embodiments of the present invention will be described below with reference to the drawings.

Embodiment 1 FIG. 4 is a diagram showing a method for determining a maintenance and inspection period for one equipment in the method for maintaining and inspecting equipment according to the embodiment of the present invention.

In FIG. 4, a recommended inspection period t specified by a manufacturer is preset for the equipment. After the installation of the equipment, perform the first maintenance inspection according to the recommended inspection period.
It is performed after the lapse. At this time, if no abnormality is found in the equipment, the specified date α is added to t, and the new maintenance inspection period is set to t + α. If no abnormality is found in the second maintenance inspection performed at t + α after the first inspection, α is added again to the maintenance inspection period, and the maintenance inspection period becomes t + 2α. At the time of the third maintenance inspection performed at t + 2α after the second inspection, if an abnormality is found in the equipment, the maintenance inspection period of the equipment is returned to the previous one, that is, the specified maintenance date from the current maintenance inspection period Subtract α to set the new maintenance inspection period to t
+ Α. Then, the maintenance / inspection period is set as an optimal maintenance / inspection period of the equipment. Abnormality here means
It refers to the operation or state of equipment that can be discovered during maintenance and inspection and that may cause a failure in the future, not visual abnormality such as equipment failure or malfunction.

That is, according to the embodiment of the present invention, a new maintenance inspection period is extended by a specified date for a recommended inspection period that is set short, unless an abnormality is found, and a new maintenance inspection period is set for the first time. Is regarded as the optimal maintenance inspection period, which is the period most suitable for the maintenance inspection period.

Further, even if a maintenance inspection is performed after setting the optimum maintenance inspection period and no abnormality is found, the maintenance inspection period is not extended. Therefore, the optimal maintenance and inspection period is reduced each time an abnormality is found. This corresponds to the necessity of increasing the frequency of maintenance and inspection because the number of failures increases as the number of hours of use of the equipment increases.

In the maintenance and inspection method according to the embodiment, the maintenance and inspection period is extended if no abnormality is found during the maintenance and inspection, and if the abnormality is discovered, one of the equipments for which the recommended inspection period is set is extended. By returning to the previous maintenance inspection period and setting the maintenance inspection period at this time as the optimal maintenance inspection period,
It is possible to obtain an optimum maintenance and inspection period of the equipment based on the results of the actual maintenance and inspection, and to reduce the maintenance and inspection costs.
