Title:
ABNORMALITY DETERMINATION SYSTEM AND ABNORMALITY DETERMINATION METHOD FOR PRESSURE-FEEDING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2019/106928
Kind Code:
A1
Abstract:
An abnormality determination system 100 is provided with: a tank 4 that stores drainage; a pressure-feeding apparatus 1 that intermittently pressure-feeds the drainage in the tank 4 by repeating a storage mode for temporarily storing the drainage from the tank 4 and a pressure-feeding mode for pressure-feeding the stored drainage by steam; a water level sensor 5 that detects the storage amount of the drainage in the tank 4; pressure sensors 6 that detect intermittent operation of the pressure-feeding apparatus 1 in the storage mode and the pressure-feeding mode; and a determination unit 7 that performs determination as to abnormality of the pressure-feeding apparatus 1. If the water level of drainage detected by the water level sensor 5 exceeds a predetermined first water level threshold value L1 or a predetermined second water level threshold value L2 and intermittent operation is not detected by the pressure sensors 6, the determination unit 7 determines that an abnormality is present in the pressure-feeding apparatus 1.
