Document Type and Number:
Japanese Patent JP7316871
Kind Code:
B2
Abstract:
To provide a management data acquisition method capable of acquiring management data for evaluating a pump device in a stable state of high reliability.SOLUTION: The present invention relates to a management data acquisition method for a pump device which drains a liquid within a water tank. The method includes: a measurement data acquisition step of time-sequentially acquiring one or more pieces of measurement data including a pump discharge pressure or a pump discharge flow rate to be used for state evaluation of the pump device; an arithmetic processing step of calculating variations of the pump discharge pressure or the pump discharge flow rate on a preset time phase basis based on the measurement data acquired in the measurement data acquisition step; and a management data extraction step of extracting measurement data to be adopted as management data for the state evaluation of the pump device based on the variations calculated in the arithmetic processing step.SELECTED DRAWING: Figure 4
