    Abstract: Embodiments of a system, controller, and method for operating a plurality of pumps for a turbine driven fracturing pump system used in hydraulic fracturing are disclosed. In an embodiment, a method of operating a plurality of pumps associated with a hydraulic fracturing system includes receiving a demand Hydraulic Horse Power (HHP) signal. The demand HHP signal may include the Horse Power (HP) required for the hydraulic fracturing system to operate and may include consideration for frictional and other losses. The method further includes operating available pump units at a percentage of rating below Maximum Continuous Power (MCP) level, based at least in part on the demand HHP signal. Furthermore, the method may include receiving a signal for loss of power from one or more pump units. The method further includes operating one or more units at MCP level and operating one or more pump units at Maximum Intermittent Power (MIP) level to meet the demand HHP signal.

    Abstract: The invention provides a variable speed hydraulic pump designed to operate at a maximum horsepower throughout its pressure range by adjusting motor speed according to motor load parameters. In particular, the variable speed hydraulic pump includes a hydraulic pump unit coupled to a variable speed electric motor by a drive unit and to a hydraulic fluid tank for pressurizing and pumping hydraulic fluid when operated by the motor. A motor controller is electrically connected to the motor to supply drive signals to the motor based on electrical characteristics of the drive signals which are dependent on the load exerted on the motor. Suction from the load is provided by both the main pump and a bidirectional supercharging pump by reversing the direction of the motor and shifting a 4/3 valve to connect the main pump inlet to the load and its outlet to tank. In addition, the controller reduces the motor speed at the maximum rated pressure to just maintain the pressure, to reduce the amount of fluid pumped through the maximum pressure relief valve.

    Abstract: A control system for a hydraulic pump of the variable displacement type using a pair of coaxially arranged pressure responding pistons. The control system comprises a servo valve for controlling a conduit of pump delivery pressure which is to be applied to a larger chamber of a servo cylinder in response to the pump delivery pressure and external pilot pressure. The servo valve includes a servo spool for controlling the conduit in order to control the pump delivery pressure, a servo sleeve for movably receiving the servo spool, a pump delivery pressure responding piston for biasing the servo spool in response to the pump delivery pressure, an external pilot pressure responding piston adapted for biasing the servo spool in response to the external pilot pressure and being coaxially arranged with the pump delivery pressure responding piston. The lever assembly causes the servo sleeve to move in accordance with the movement of the servo piston. The lever assembly has an inclined surface part for causing displacement of the servo piston as a function of displacement of the pressure responding pistons to show a characteristic hyperbola.

    Abstract: A servomechanism for pump capacity control includes an adjustable throttle of the "nozzle-gate" type formed with two operating slots communicating through two fixed throttles with duct, a source of supply feeding the duct, an input signal converter whose movable element is connected to the gate of the nozzle-gate throttle and a four-slot, five-line distributor whose control spaces are in communication through two fixed throttles with the duct of the source of supply, two operating slots being formed in the adjustable throttle, whereas its operating spaces communicate with the corresponding spaces of an actuating hydraulic cylinder. The latter is connected to the control element and, by a mechanical position feedback, to the gate. The mechanical position feedback is constituted by a bar which is linked to the movable element of the hydraulic cylinder and has a slanted surface. The slanted surface interacts with a spring-loaded pusher, whose springs act on the gate. The servomechanism incorporates a device which ensures linear dependence of the speed of hydraulic cylinder movement on the displacement of the gate away from the neutral position, and acts on the slide valve of the four-slot five-line distributor. The servomechanism additionally includes a mechanism for limiting the power of the controlled pump, the mechanism being linked mechanically with the hydraulic cylinder and the gate of the nozzle-gate throttle, and hydraulically with the discharge line of the controlled pump.
