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.

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.

Abstract: In some implementations, a controller may obtain an indication of a first crank angle associated with a first pump, of a dual-pump single-power source system, that is mechanically connected to a power source of the dual-pump single-power source system via a first clutch. The controller may obtain an indication of a second crank angle associated with a second pump, of the dual-pump single-power source system, that is mechanically connected to the power source via a second clutch. The controller may determine that a difference between the first crank angle and the second crank angle is outside of a tolerance of a crank angle difference value. The controller may modulate a fluid pressure associated with at least one of the first clutch or the second clutch to cause the difference between the first crank angle and the second crank angle to be within the tolerance of the crank angle difference value.

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.

Abstract: In some implementations, a controller may obtain a set of measurement values associated with the dual-pump single-power source system, wherein the set of measurement values includes at least one of one or more speed measurements associated with a clutch that is coupled to a power source and a first pump of the dual-pump single-power source system, a measurement value indicating an output speed of the power source, or a first crank angle associated with the first pump and a second crank angle associated with a second pump of the dual-pump single-power source system. The controller may detect that the clutch is experiencing slippage based on comparing at least two measurement values of the set of measurement values. The controller may perform an action to cause the clutch to disengage a mechanical connection between the first pump and the power source while the power source is running and is mechanically connected to the second pump.

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.
