Abstract
A system and a method for producing fracturing fluid, comprising: engaging an engagement coupling attached to one end of a gear box dual shaft to a gear box connector of an external gear box, wherein the external gear box is part of a pump; rotating the gear box dual shaft to drive the pump after engaging the engagement coupling with the gear box connector; disengaging the engagement coupling from the gear box connector; and rotating the gear box dual shaft without driving the pump after disengaging the engagement coupling with the gear box connector.
Claims20
A fracturing transport, comprising:
- an electric motor having a motor shaft and being operable to transmit drive to the motor shaft;
- a pump disposed adjacent the electric motor;
- an external gear box connected to the pump, the external gear box including a housing whose dimensions are disposed between the electric motor and the pump, wherein the housing defines a gap between a side of the pump facing the electric motor and a side of the housing facing the pump;
- a drive shaft coupled to the motor shaft and driven by the transmitted drive, the drive shaft disposed between the electric motor and the external gear box;
- a gear shaft that is disposed on the external gear box and that is coupled to the drive shaft to drive a gear of the external gear box, the gear shaft comprising first and second ends extending from opposite sides of the housing of the external gear box, the first end of the gear shaft disposed toward the electric motor and coupled to the drive shaft, the second end of the gear shaft extending into the gap;
- and
- an engagement coupling disposed at the second end of the gear shaft in the gap, the engagement coupling being selectively coupleable between a coupled condition and an uncoupled condition, wherein the engagement coupling in the coupled condition transfers the transmitted drive to the gear of the external gear box, and the engagement coupling in the uncoupled condition isolates the transmitted drive from the gear of the external gear box.
A method of pumping fracturing fluid with a pump having a fluid end assembly powered by a power end assembly driven by an electric motor, the method comprising:
- operating the electric motor having a motor shaft and operable to transmit drive to the motor shaft, wherein the pump is disposed adjacent the electric motor, and an external gear box is connected to the pump, the external gear box including a housing whose dimensions are disposed between the electric motor and the pump, wherein the housing defines a gap between a side of the pump facing the electric motor and a side of the housing facing the pump;
- transferring the drive of the motor shaft to a drive shaft coupled to the motor shaft, the drive shaft disposed between the electric motor and the external gear box;
- driving aa gear shaft that is disposed on the external gear box and that is coupled to the drive shaft, the gear shaft comprising first and second ends extending from opposite sides of the housing of the external gear box, the first end of the gear shaft disposed toward the electric motor and coupled to the drive shaft, the second end of the gear shaft extending into the gap;
- and
- selectively transferring the drive to a gear of the external gear box by operating an engagement coupling disposed at the second end of the gear shaft in the gap, wherein the engagement coupling is selectively coupleable between a coupled condition and an uncoupled condition, the engagement coupling in the coupled condition transferring the drive of the gear shaft to the gear of the external gear box, and the engagement coupling in the uncoupled condition isolating the drive of the gear shaft from the gear of the external gear box.
