Abstract
PURPOSE: To prevent generation of beat phenomena and operation without conveying water by making arranged velocity controls giving a settled velocity difference to each pump in a pump system to be required to provide flow controls in response to consuming rate for water works system or another.
CONSTITUTION: Since flow rate to be conveyed is preset in a flow controller 10 differential signals are sought out between the set flow signals and flow signals conveyed through a flow meter 9, and the differential signals are supplied to an arranged velocity controller 11 and a unit number controller 12 which control so that two pumps 8a, 8b in other words motors 13a, 13b can be rotated by a settled velocity difference. Thus, arranged velocity control is done by giving a settled velocity difference. Thus, arranged velocity control is done by giving a settled velocuty difference to the pumps 8a, 8b, with prevention of jarring beat phenomena, by reason that the velocity difference between the pumps has flow characteristic curve of each pump set to almost the same, flow distribution is equalized with possibility of preventing operation without conveying water.
