Title:
ABNORMALITY DETECTION DEVICE FOR LUBRICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/031366
Kind Code:
A1
Abstract:
This abnormality detection device is provided with: a plurality of flow detectors 30 that detect the flow of lubricating oil by opening/closing respective valve bodies 40; a temperature sensor S that detects the temperature of the lubricating oil; and a management unit 60 that conducts abnormality management of a lubricating system J on the basis of the detected temperature of the temperature sensor S and opening/closing of the valve bodies 40 of the flow detectors 30. The management unit 60 is provided with: an opening/closing detection means 62 for detecting opening/closing of the valve bodies 40 of the flow detectors 30; an opening start time calculation means 63 for calculating the opening start time of the valve bodies 40; an opening start time determination means 66 for determining whether the opening start time of the valve bodies 40 is within an appropriate opening start time range derived from the correlation with the temperature of the lubricating oil; and an abnormality determination means 67 for determining an abnormality when the opening start time determination means 66 determines that the opening start time is outside the range for at least one of the flow detectors 30.
