Abstract

The disclosure relates to a method for preventing damage to a multiphase pump, comprising measuring the differential pressure of a fluid across a multiphase pump over a time period and measuring the axial position of a rotor of the multiphase pump over a time period. The method also involves calculating a pressure fluctuation by measuring the difference between a maximum value of the measured differential pressure and a minimum value of the measured differential pressure over the time period and calculating a dynamic axial position by measuring the difference between a maximum value of the axial position of the rotor and a minimum value of the axial position of the rotor over the time period. Also involved in the method is comparing the calculated pressure fluctuation of the multiphase pump with an expected pressure fluctuation value, and comparing the calculated dynamic axial position of the rotor with an expected dynamic axial position value, and selecting an operating condition of the multiphase pump from one of expected operation, surge operation and choke operation based on the comparison between the calculated pressure fluctuation and the expected pressure fluctuation value, and the comparison of the calculated dynamic axial position and the expected axial position value.

An axial stop prevent axial movement relative to the housing of one of the screw and the threaded part in a normal mode of operation. A primary drive provides a rotational movement to the screw assembly in the normal mode of operation. The screw assembly converts the rotational movement to an axial movement of a valve member 10 relative to the housing. An override is provided for operating the actuator in an override mode of operation, the override releasing at least one of the screw and the threaded part for axial movement relative to the housing in the override mode.
