摘要：Problem to be solved: to provide a water supply device capable of preventing adecrease in overall efficiency. Control unit 54 of water supply device 1The pump unit 14 isoperated independently.When the operating frequency of pump device 14 reaches themaximum frequencyThe standby pump 14 is increasedThe first pump 14 is operated at a
speed andUp to the same frequency as pump 14The increased pump unit 14 is increasedfor every predetermined frequency stepThe pressure detected by the pressure detector21 for each frequency stepThe total efficiency is calculated from the water supplyamount and the consumed power detected by the flow rate detecting part 20, and theoperation part 52 is used54.When the total integrated efficiency was the highest, thepump 14 was raised at the operating frequency of the pump 14, and the constant speedoperation was performed.The pump unit 14 which has been leading to the targetpressure is shifted.Diagram
