  • Publication number: 20240052826
    Abstract: In some implementations, a controller may monitor, in connection with a fluid pump driven by a motor that is controlled by a variable frequency drive and over a time period, a torque of the motor to obtain torque data, a speed of the motor to obtain speed data, and a pressure of the fluid pump to obtain pressure data. The controller may determine that the fluid pump is associated with a leak of a particular severity level based on the torque data indicating a deviation that satisfies a first threshold, the speed data indicating a deviation that satisfies a second threshold, and the pressure data indicating a deviation that satisfies a third threshold. The controller may perform at least one operation based on the particular severity level of the leak.

  • Patent number: 11898551
    Abstract: An example system includes a fluid end having a block, a fluid inlet formed in the block, and a fluid outlet formed in the block. The system also includes an intake manifold fluidly coupled to the fluid inlet, and a fluid conduit fluidly coupled to the fluid outlet and the intake manifold. The system further includes a valve fluidly coupled to the fluid conduit, the valve configured to control fluid flow through the fluid conduit, an actuator coupled to the valve and configured to position the valve in an open position or a closed position, and a controller communicatively coupled to the actuator and configured to send one or more signals to the actuator, causing the actuator to position the valve in the open position or the closed position.

  • Patent number: 11808139
    Abstract: A method may include monitoring, by a controller, operation of a pump of at least one hydraulic fracturing rig during ramp-up of the pump. Each of the at least one hydraulic fracturing rig may further include an engine and a transmission. The method may further include detecting, by the controller, an issue in the operation of the pump based on the monitoring of the operation and performing an action based on the detecting of the issue.

  • Patent number: 11808225
    Abstract: In some implementations, a controller may determine, in connection with a constant speed operation of an engine operable by spark ignition of a gaseous fuel, that a transient event associated with the engine is to occur, the transient event to cause a shift from a first gear to a second gear of a transmission coupled to the engine, where the shift from the first gear to the second gear is to increase a primary load associated with the engine. The controller may cause, prior to the shift from the first gear to the second gear, increasing of an auxiliary load associated with the engine. The controller may cause, during the shift from the first gear to the second gear, decreasing of the auxiliary load.

  • 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: 20230243350
    Abstract: In some implementations, a controller may monitor, during a ramp up period of a fluid pump driven by a motor that is controlled by a variable frequency drive (VFD), an intake pressure of the fluid pump and a discharge pressure of the fluid pump. The controller may detect, based on monitoring the intake pressure and the discharge pressure, whether the intake pressure satisfies an intake pressure threshold or the discharge pressure satisfies a discharge pressure threshold. The controller may cause, via the VFD, reduction of a torque of the motor based on the intake pressure satisfying the intake pressure threshold or the discharge pressure satisfying the discharge pressure threshold.
