Abstract
PURPOSE: To perform the control of flow, etc., by matching the axial outputs of each pump by returning values proportional to the magnitude of exciting current of exciting coupling.
CONSTITUTION: The flow controller consists of the exciting coupling device 9 by which to transmit the rotation of the induction motor 8 to the pump 3, the operator 10 by which to operate the axial output, the tachometer generator 6 for detecting the rotation number of pump, and the speed control circuit 5 by which to change the rotation number of the pump 3 by changing the current 7 by comparing and amplifying the exciting current 7, the speed command value 4, and the axial output 10. Considering the product of multiplying the exciting current 7 of the exciting coupling device 9 by the rotation number 6 to be the axial output of the pump 3 and also the lift head to be constant, the return 6a of the rotation number and the return 7a of exciting current are calculated by using the speed set value 4 as the set value of axial output by the arithmetic unit 10, and the result is used as the return value 10a of axial output to control the axial output.
