A system for cooling a generator includes a generator system. The generator system includes a generator, an enclosure, the enclosure surrounding the generator, and a radiator, wherein the radiator is fluidly connected to the generator. The system also includes a radiator and ventilation fan system. The radiator and ventilation fan system includes a controller. The radiator and ventilation fans system also includes a ventilation fan variable frequency drive (VFD), the ventilation fans VFD in electrical communication with the controller and a ventilation fan in electrical communication with the ventilation fans VFD. In addition, the radiator and ventilation fan system includes radiator fans VFD in electrical communication with the controller and a radiator fan in electrical communication with radiator fans VFD. Further, the system includes temperature sensors, the temperature sensors in electrical communication with the controller.

A system includes a generator and an enclosure surrounding the generator, the generator having an air intake and an inside surface. The system also includes an air intake housing affixed to the inside surface of the enclosure and fluidly connected to the air intake, the air intake housing terminating in an air intake housing inner plate positioned at inner edge of the air intake housing. The air intake housing inner plate has a plurality of air intake holes. In addition, the system includes a damper, the damper abutting the air intake housing inner plate, the damper having a plurality of damper holes. The damper is adapted to slide along the air intake housing inner plate.

An integrated fracking system includes a substructure assembly including one or more frame rails. The integrated fracking system includes a pump subsystem having a frac pump and a motor. The pump subsystem is coupled to the frame rails of the substructure assembly. The integrated fracking system includes a variable frequency drive, a transformer, and a cooling subsystem, each coupled to the frame rails of the substructure assembly.

Integrated fracking system

A well servicing pump system for a hydraulic fracturing system includes a first permanent magnet motor, second permanent magnet motor, and crankshaft. The first and second permanent magnet motors each include a rotor mechanically coupled to or integrated with the crankshaft. The well servicing pump may include gearboxes coupled between the rotors and the crankshaft. The well servicing pump system also includes a fluid section that includes an inlet, a pressurization chamber, and an outlet. The inlet and outlet are fluidly coupled to the pressurization chamber. The well servicing pump also includes a plunger mechanically coupled to the crankshaft, the plunger at least partially positioned within the pressurization chamber.

The integrated fracking system may include a variable frequency drive (VFD) coupled to the frame rails of the substructure assembly. The integrated fracking system may include a transformer coupled to the frame rails of the substructure assembly. The integrated fracking system may include a pump subsystem. The pump subsystem may include a first frac pump, a first motor operatively coupled to the first frac pump, a second frac pump, and a second motor operatively coupled to the second frac pump. The pump subsystem may be coupled to the frame rails of the substructure assembly.

Dual pump integrated fracking system

A frac system includes power generation equipment and a power storage device used to provide electric power to one or more pieces of frac equipment. The frac system includes a power controller used to control the source of the power to the frac equipment. The power controller may measure the charge status for the power storage device and the electrical power load being used by the frac equipment. The power controller may engage or disengage the power generation equipment based on the measured charge status and electrical power load, may control the source of the power provided to the frac equipment, and may control whether the power storage device is being charged.
