Abstract
A method for preventing damage to a multiphase pump includes measuring a differential pressure of a fluid across the pump and an axial position of a rotor of the pump over a time period, calculating a pressure fluctuation by measuring a difference between a maximum and a minimum value of the measured differential pressure over the time period, calculating a dynamic axial position by measuring a difference between a maximum and a minimum value of the measured axial position of the rotor over the time period, comparing the calculated pressure fluctuation with an expected pressure fluctuation value, comparing the calculated dynamic axial position with an expected dynamic axial position value, and selecting an operating condition of the pump based on the comparison of the calculated pressure fluctuation with the expected pressure fluctuation value and of the calculated dynamic axial position with the expected dynamic axial position value.
