  • Publication number: 20230287775
    Abstract: A controller that is associated with a pump system causes a power ramp rate of a motor of the pump system to have an initial power ramp rate. The controller monitors, after causing the power ramp rate of the motor to have the initial power ramp rate, a frequency of a power bus. One or more power sources provide power to the pump system via the power bus. The controller causes, based on monitoring the frequency of the power bus, the power ramp rate of the motor to be modified.

  • Publication number: 20230243351
    Abstract: In some implementations, a controller may obtain a setting for a maximum discharge pressure associated with a fluid pump that is to be allowed during a hydraulic fracturing operation. The fluid pump may be driven by a motor that is controlled by a variable frequency drive (VFD). The controller may determine a maximum torque for the motor that achieves the maximum discharge pressure. The controller may cause, via the VFD, adjustment to a speed of the motor to maintain a torque of the motor at or below the maximum torque for the motor.

  • Publication number: 20230243348
    Abstract: In some implementations, a controller may obtain a setting for a target discharge pressure associated with a fluid pump driven by a motor that is controlled by a variable frequency drive (VFD). The target discharge pressure may be for use in a pressure test of a system that includes the fluid pump. The controller may determine a target torque for the motor that achieves the target discharge pressure. The controller may cause, via the VFD and in connection with the pressure test, adjustment to a speed of the motor to achieve the target torque for the motor.

  • Publication number: 20230233334
    Abstract: Stand-alone interbody fusion devices for engagement between adjacent vertebrae. The stand-alone interbody fusion devices may include a spacer and one or more inserts or members coupled to the spacer. The inserts or members may be configured and designed to provide the apertures which are designed to retain bone fasteners, such as screws, and secure the implant to the adjacent vertebrae.

  • Patent number: 11686186
    Abstract: In some implementations, a controller may monitor an available power supply of at least one power source for a system for hydraulic fracturing, and a current power demand of the system. The controller may determine, based on monitoring the available power supply and the current power demand, whether a relationship between the current power demand and the available power supply is indicative of an impending power failure. The controller may cause, based on determining that the relationship between the current power demand and the available power supply indicates the impending power failure, reduction of flow rates of one or more fluid pumps of the system to reduce the current power demand.

  • Patent number: 9447746
    Abstract: A control system of an engine is provided. The control system includes an inlet sensor configured to generate a signal indicative of an engine inlet air temperature and an intake manifold sensor configured to generate a signal indicative of an engine intake manifold air temperature. The control system includes a control module communicably coupled to the inlet sensor and the intake manifold sensor. The control module is configured to determine the engine inlet air temperature and the engine intake manifold air temperature. The control module is configured to determine an initial de-rate value based on a predetermined relationship between the engine inlet air temperature and the engine intake manifold air temperature. The control module is configured to determine a pre-stored de-rate modifier corresponding to an engine speed. The control module is configured to determine a final de-rate value based on the initial de-rate value and the pre-stored de-rate modifier.
