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.

Abstract: A pinion shaft assembly for operation in a power end of a reciprocating pump includes a tubular member coupled to first pinion gear member via an interference coupling extension, possibly having a protruding alignment key operable to engage a slot formed on an inner wall of the first end of the tubular member to ensure correct rotational orientation of the first pinion gear member and the tubular member and to help prevent rotation of the first pinion gear member relative to the tubular member. The tubular member is also coupled to a second pinion gear member via an interference coupling extension, possibly having a protruding alignment key operable to engage a slot formed on an inner wall of the second end of the tubular member to ensure correct rotational orientation of the second pinion gear member and the tubular member and to help prevent rotation of the second pinion gear member relative to the tubular member.
