Abstract
PURPOSE: To reduce the total number of pumps put in operation and minimize the running cost of the system, by reducing the number of pumps in operation in earliest stages.
CONSTITUTION: A group of pumps 4 are turned on or off through a pump controller 2 according to a pumping schedule 1 and water in a pumping well 3 is pumped under pressure by the pumps 4 through a flow control valve 5. The number of pumps in operation at the current time is checked in accordance with the schedule. If the number of pumps scheduled at a time in the future may be less than that at the current time by one and in addition, the current number of pumps in operation may be reduced by one for feeding a required amount of water, the number of pumps in operation is reduced by one prior to the scheduled time. This can reduce the frequency of starting or stopping the pumps, minimize the total number of pumps put in operation and thus reduce the running cost of the pumps.
