If the pump’s motor is started in a situation where oil is flowing back to the reservoir, the pump is forced to rotate in a reverse direction. This situation causes torque that can be very stressful for the motor shaft, potentially resulting in a failure. Backspin control detects the rotating rotor and delays restart, until it is safe to execute. Utilizing this method, a user can get rid of backspin timers, eliminate production delays and increase the well output.
In case the normal pumping mode is requested, a flying start (i.e. starting into the rotating motor) is also possible during the backspin procedure.
