Hydraulic fracturing system and method for optimizing operation thereof

A method for operating a hydraulic fracturing system, the method comprising steps of:

• transferring torque from an engine to a hydraulic fracturing pump using a transmission and a driveshaft;
• receiving, by a controller, information identifying pump flow and pressure settings;
• identifying an optimal transmission gear, using the controller, based on the pump flow and pressure settings and component durability data, the component durability data including transmission gear life prediction data and pump cavitation prediction data, and wherein the pump cavitation prediction data includes inlet pressure values corresponding to a potential pump cavitation event;
• and provide information identifying the optimal transmission gear.

A control system for a hydraulic fracturing system, including:

• a memory storing component durability data;
• and a controller programmed to:
• receive information identifying pump flow and pressure settings;
• identify an optimal transmission gear based on the pump flow and pressure settings and the component durability data, the component durability data including transmission gear life prediction data and pump cavitation prediction data, and wherein the pump cavitation prediction data includes inlet pressure values corresponding to a potential pump cavitation event;
• and provide information identifying the optimal transmission gear.
