A system and method for operating a fleet of pumps for a turbine driven fracturing pump system used in hydraulic fracturing is disclosed. In an embodiment, 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 at least in part 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.

Embodiments of an enclosure assembly to enhance cooling of a hydraulic fracturing direct drive unit (DDU) during operation are included. The enclosure assembly may include an enclosure body extending at least partially around an enclosure space to house the DDU for driving a fluid pump. The enclosure assembly may include one or more heat exchanger assemblies connected to the enclosure body for cooling a process fluid associated with one or more of the DDU and the fluid pump, and which may be configured to draw air into the enclosure space from and external environment, toward one or more radiator assemblies to cool the process fluid, and along an airflow path through the enclosure space. One or more outlet fan assemblies may be operative to discharge air from the enclosure space to the external environment to maintain a desired temperature of the enclosure space.

The present invention discloses a semi-trailer-loaded turbine fracturing equipment, which adopts a linear connection of the whole equipment and a special chassis design, so that the center of gravity is double lowered to guarantee its stability and safety, the structure is simpler, the investment and operation costs are decreased, the risk of total breakdown of the fracturing site is reduced, and the equipment has a good transmission performance and is suitable for continuous operation conditions with long time and heavy load. The plunger pump is improved in that the distance between the center of rotation of the bellcrank and the center of rotation of the crankshaft is optimized so that the rated input power is increased to 5000-7000 hp, the transmission ratio of the reduction gearbox integrated on the plunger pump is optimized so that the maximum input speed can reach 16000 rpm, the superhigh speed allows the reduction gearbox to be connected directly to the turbine engine to address the problem that the turbine fracturing equipment is decelerated through two reduction gearboxes, thus decreasing the weight of the vehicle and reducing the overall size of the equipment.

A rod-pump control device is disclosed. The claimed rod-pump control device uses fuel or air usage for gas units, and can use pressure. The sensors work as the primary trigger to indicate a pump-off condition on an oil and gas well. These sensors can be used as stand-alone triggers or in conjunction with other sensors to more accurately monitor pump efficiency. When the pump-controller starts to indicate an inefficient pump condition, it will remove power to disengage an electric clutch or send a signal to an engine controller to stop. An adjustable algorithm will use percentage change of off time, dependent on actual run time compared to a user definable target time to keep the pump operating at peak efficiency.
