Abstract

PURPOSE: To secure a preferable control on a parallel operation of pumping equipment by employing a constitution wherein an adjusting pump variable for operation and a pressure pump working merely for intermittence are combined.
CONSTITUTION: An adjusting pump system 1 comprises a rotational speed controlling device (using a frequency converter) and an adjusting pump P0. A pressure pump system 2 comprises the first controlling device 5 and pressure pumps P1WP3 connected thereto. A control system 3 comprises a pressure switch PS and the second controlling device 6. A mode transfer switch 7 is connected to a control end of the frequency converter 4 and transferred in interlocking with on/off operation of the pressure pumps P1WP3 by the first controlling device 5, thus transferring a mode of the frequency converter 4. The second controlling device is connected to a control end of the rotational speed controlling device through the switch PS. Thus, a preferable control can be secured on a parallel operation of pumping equipment.
