Abstract

Techniques are provided for protecting a twin screw positive displacement pump, that include a signal processor that receives signaling containing information about power, torque, speed, viscosity and specific gravity related to the operation of the twin screw positive displacement pump; and determines whether to enter an enhanced pump protection mode for the twin screw positive displacement pump based on a relationship between an actual corrected tune ratio and a tuned ratio set point (Tune Ratio SP). In operation, the signal processor determines if the actual corrected tune ratio is <= the actual corrected tune ratio set point (Tune Ratio SP), and if so, then enters the enhanced pump protection mode, else continues to use a basic pump protection mode, and also determines the actual corrected tune ratio based on a ratio of an actual corrected torque (TAcorr) divided by a tuned corrected torque (TTcorr) at a specific operating speed.
