Document Type and Number:
Japanese Patent JP2022183793
Kind Code:
A
Abstract:
To provide a technology which is effective for suppressing an erroneous notification of abnormalities in two pumps which are linked through water transfer.SOLUTION: A pump abnormality notification device 10 for notifying abnormalities in two pumps P1, P2 which are linked through water transfer comprises: current sensors 11, 12 as information detection parts for detecting pump operation information D1, D2 related to the operation frequencies M1, M2 of the two pumps P1, P2; a storage part 22 for accumulating the pump operation information D1, D2 detected by the current sensors 11, 12; and notification parts 23, 24 and 25 for notifying the abnormalities in the two pumps P1, P2 on the basis of the pump operation information D1, D2 read out of the storage part 22. When a state that an operation frequency difference ΔM per unit time between the two pumps P1, P2 exceeds a threshold Ma is continued for a management frequency Na or more, the notification parts 23, 24 and 25 output abnormality notification signals.SELECTED DRAWING: Figure 1
