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.

Abstract: Disclosed herein is a hydraulic-pump controller that is capable of controlling absorbed pump torque in good balance against engine output at all times. In this hydraulic-pump controller, the discharge flow rates of the operating oil that are discharged from hydraulic pumps (9, 10) according to manipulation of manipulation units (12, 13) are predicted based on the discharge pressure of the hydraulic pumps (9, 10) that are driven by an engine (1), and based on the manipulation amount of the manipulation units (12, 13) that manipulate hydraulic actuators (27, 28), or a physical quantity correlating with the manipulation amount. Based on the predicted discharge flow rates and the discharge pressure, the absorbed torque of the hydraulic pumps is computed. Then, the predictive engine speed of the engine (11) is computed from the absorbed torque of the hydraulic pumps (9, 10) computed. Based on the deviation between the computed predictive engine speed and the actual engine speed of the engine (11), the regulators (12, 13) of the hydraulic pumps (9, 10) are controlled.

Abstract: A pump enable system includes a variable-displacement piston pump having a displacement control device. The displacement control device controls displacement of pistons in the pump based on a position thereof, and a position control system in the pump controls a position of the displacement control device based on a load on the pump. An over-ride system selectively over-rides the position control system such that the displacement control device assumes a position which reduces displacement of the pistons in the pump.

Abstract: A pump system includes a variable fluid displacement pump having a pressure line which is connected to a pressure load and connected to a load sensing control. A variable orifice is located downstream from the load sensing control. The variable orifice is fluidly connected to the load sensing control in a servo pressure conduit such that the margin pressure varies proportionally with respect to the fluid displacement Of the pump. The variable orifice can take many different forms, including a variable cross sectional area gap between the housing and an elongated servo piston longitudinally slidable therein. A longitudinal slot having uniformly increasing depth along the length of the servo piston gives the servo piston a cross sectional area which varies along its length. Thus, a variable orifice results.

Abstract: A system and method for operating a fleet of pumps for a turbine driven fracturing pump system used in hydraulic fracturing is disclosed. A method of operating a fleet 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 all available pump units at a percentage of rating below Maximum Continuous Power (MCP) level, based 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 units at Maximum Intermittent Power (MIP) level to meet the demand HHP signal.
