Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a pump control device and a pump operating method capable of effectively restricting a power consumption by controlling a starting and a stopping of a pump for operation under an effective utilization of capacity of pump facility.SOLUTION: This invention relates to a pump control device that is installed at a water storage facility comprising a water storage tank, a water level meter for measuring a water level at said water storage tank and a pump for adjusting the water level in said water storage tank. When the water level in the water storage tank measured by said water level meter becomes a starting water level, said pump is started and then when it becomes a stopping water level, said pump is stopped. As said water stopping level, the first water stopping level and the second water stopping level that is set to said starting water level side in reference to said first stopping water level on the basis of a consumption power per unit water feeding amount of said pump can be set and any one of said first stopping water level and said second stopping water level is set to said stopping water level with either a feeding-in water amount or a feeding-out water amount per a specified time for said water storage tank being applied as an index.SELECTED DRAWING: Figure 3
