Abstract
A method for preventing or reducing mechanical vibrations of a pump, in particular a centrifugal pump, during pump operation is provided. A pump controller detects at least one signal of a pump operation parameter and identifies signal fluctuations in order to detect mechanical vibrations occurring in the pump. The pump controller controls the frequency converter to modify the pump speed in order to reduce a detected pump vibration.

A method for preventing or reducing mechanical vibrations of a pump having a frequency converter and a pump controller, comprising the steps of:
- detecting with the pump controller at least one signal of a pump operating parameter;
- analyzing with the pump controller the at least one signal to identify signal oscillations characteristic of mechanical vibrations of the pump;
- and
- changing the pump revolution rate by the pump controller controlling the frequency converter to reduce the mechanical vibrations of the pump.
A pump arrangement, comprising:
- a pump;
- a frequency converter;
- and
- a pump controller,
- wherein the pump controller is configured to
- receive at least one signal of a pump operating parameter,
- analyze the at least one signal to identify signal oscillations characteristic of mechanical vibrations of the pump, and
- control the frequency converter to change the pump revolution rate to reduce the mechanical vibrations of the pump.
