とするボイラー用給水システムの異常検出装置。[Scope of Claim for Utility Model Registration] A plurality of water level detectors 2 and 3 are installed in the water level control box 1 attached to boiler B, and the water level in the boiler is determined based on the signals from these water level detectors 2 and 3. In a water supply system equipped with a controller 4 that controls the water supply pump P ON-OFF in order to maintain it within the control range of In preparation, the pressure change Δp is detected by the pressure sensor 10 after a predetermined time Δt 0 has passed since the water supply pump P starts operating, and if the pressure change is less than the predetermined value Δp 0 ,
If it is determined that an abnormality has occurred in the water supply pump P, the pressure change is greater than a predetermined value Δp 0 , and the signals from the plurality of water level detectors 2 and 3 contradict each other, the water level detector 2 An abnormality detection device for a boiler water supply system, comprising a detection device 30 that determines that an abnormality has occurred in the boiler water supply system.
