Abstract
A method for operating a pump, for conveying a fluid from a low-pressure side to a high-pressure side of the pump includes determining a current rate of change of pump vibrations and comparing the current rate of change with a limit for the rate of change or determining a current vibration of the pump and comparing the current vibration with a vibration amplitude limit for the vibration, storing the limit for the rate of change or the vibration amplitude limit in a surge controller, providing a control signal when the current rate of change reaches the limit or when the current vibration reaches the vibration amplitude limit, and changing a control variable of the pump by the control signal, such that the vibration is reduced and an unstable operating state of the pump is avoided.
