Title:
CONTROL DEVICE, CONTROL METHOD, PROGRAM AND ABNORMALITY DETECTION SYSTEM
Document Type and Number:
Japanese Patent JP2019019734
Kind Code:
A
Abstract:
To grasp a full water detection error.SOLUTION: A control device comprises: a determination part for determining a preset suction pressure that is a suction pressure of a vacuum pump 2 estimated in the case of full water or a preset current value that is a current value of the vacuum pump estimated in the case of full water by using a difference between a water level that is measured by a water gauge 7 and a full water level that a full water detector 8 discriminates as full water; a comparison part for comparing a measured pressure that is the suction pressure of the vacuum pump, measured by a pressure gauge (compound gauge) 9 with the preset suction pressure or comparing a measured current value that is a current value of the vacuum pump, measured by an ammeter with the preset current value; and a control part which performs control in such a manner that, in a case where a pair of a comparison result and a detection result of the full water detector is a preset combination, a notification should be performed.SELECTED DRAWING: Figure 1
