    摘要: A pumping system 10 that jets the fluid from the nozzle selected out of the plurality of nozzles is provided with: a piston pump 13 as a positive-displacement pump; a permanent-magnet type synchronous motor 16 as a rotational speed variable drive unit; a turret device 25 as selecting arrangement; a discharge pipe 19; the nozzle 27; a controller that controls the rotational speed of the drive unit; a storage that stores control parameters and a target value of the discharge pressure corresponding to each nozzle; and a pressure sensor 21, wherein the controller controls the rotational speed of the drive unit by feeding back the discharge pressure using the control parameters corresponding to the selected nozzle so as to match the discharge pressure with the target value. Thus, an acurate nozzle-dependent control of the reciprocating piston-pump is enabled.
