PROBLEM TO BE SOLVED: To provide an oil leakage detection system, an oil leakage detection device, and an oil leakage detection method which allow for detection of grasping a situation of oil leakage in a hydraulic elevator in detail and notifying a customer engineer of it.SOLUTION: An oil leakage detection system includes a first sensor, a second sensor, and an oil leakage detection device. The first sensor is provided in a tray installed in an oil leakage detection target part in the hydraulic elevator and detects that a preset first amount of oil is accumulated in the tray. The second sensor is installed in the tray and detects that a second amount of oil which is larger than the first amount is accumulated in the tray. When the accumulation of the first amount of oil in the tray is detected by the first sensor, the oil leakage detection device outputs first notification information. When the accumulation of the second amount of oil in the tray is detected by the second sensor, the oil leakage detection device outputs second notification information whose importance is higher than that of the first notification information.SELECTED DRAWING: Figure 3
【課題】油圧エレベータ内の油漏れの状況を詳細に把握して保守員に報知することが検出可能な、油漏れ検出システム、油漏れ検出装置、および油漏れ検出方法を提供する。【解決手段】実施形態によれば、油漏れ検出システムは、第1センサと、第2センサと、油漏れ検出装置とを備える。第1センサは、油圧エレベータ内の油漏れ検出対象箇所に設置された受け皿内に設けられ、予め設定された第1の量の油が受け皿内に溜まったことを検出する。第2センサは、受け皿内に設置され、第1の量よりも多い第2の量の油が受け皿内に溜まったことを検出する。油漏れ検出装置は、第1センサで第1の量の油が受け皿に溜まったことが検出されると、第1報知情報を出力し、第2センサで第2の量の油が受け皿に溜まったことが検出されると、第1報知情報よりも重要度の高い第2報知情報を出力する。【選択図】図3
