Abstract (en)
[origin: WO2012066090A1] The invention relates to a method for the rotational-speed-variable control of an expeller pump unit for feeding a fluid, composed of an expeller pump and a drive, wherein the drive is composed of an electric drive motor and a frequency converter, by means of a control device, wherein a final pressure of the expeller pump is adjusted to a final pressure setpoint value by the control device, as well as a suitable control device for carrying out the method and a corresponding expeller pump arrangement. The control device (11) according to the invention detects state values which are supplied by the drive, in particular relating to the position, rotational speed and torque of the drive motor (6). The control device (11) determines therefrom the control variable, in particular the final pressure of the expeller pump (2). The expeller pump unit is adjusted to the setpoint value without using sensors.
