Abstract
An electric drive pump system includes a power end and a detachable transmission assembly. The transmission assembly is mounted to the power end and is configured to provide rotational power to the power end through a plurality of electric motors. The plurality of electric motors use a gearbox to drive an output spline that engages the power end. A control module is used to regulate the performance characteristics of the plurality of electric motors. A temperature regulation assembly is configured to regulate the temperature of the transmission assembly and the power end.
Claims19
A hydraulic fracturing pump system, comprising:
- a trailer platform supported on a plurality of wheels;
- a hydraulic fracturing pump supported on the trailer platform, the hydraulic fracturing pump having a power end and a fluid end;
- at least one electric drive motor supported on the trailer platform and operably coupled to the power end to drive the power end;
- and
- a radiator and one or more fans supported above the trailer platform and forming a radiator pack that is spaced apart from the trailer platform and covers at least a portion of the platform and operable to at least one of remove heat from the electric drive motor or clear debris from the trailer.
A hydraulic fracturing pump system, comprising:
- a trailer platform;
- a hydraulic fracturing pump supported on the trailer platform, the hydraulic fracturing pump having a power end and a fluid end;
- at least one electric drive motor supported on the trailer platform and operably coupled to the power end to drive the power end;
- a frame extending from the trailer platform to a height above the hydraulic fracturing pump;
- and
- a temperature regulation assembly supported by the frame above the trailer platform wherein the temperature regulation assembly comprises a radiator and one or more fans forming a radiator pack that is spaced apart from the trailer platform and substantially parallel with the trailer platform and is operable to at least one of remove heat from the electric drive motor or clear debris from the trailer.
A hydraulic fracturing pump system, comprising:
- a trailer platform;
- a hydraulic fracturing pump supported on the trailer platform, the hydraulic fracturing pump having a power end and a fluid end, wherein the power end has a pump crankshaft extending along a crankshaft axis;
- a plurality of electric motors mounted on the hydraulic fracturing pump and radially spaced apart from one another about the crankshaft axis;
- a frame extending from the trailer platform to a height above the hydraulic fracturing pump;
- and
- a panel supported by the frame above the trailer platform, wherein the panel comprises a radiator and a plurality of fans, the radiator in fluid communication with at least one of the power end and the plurality of electric motors, wherein the panel is disposed above the trailer platform and substantially parallel with the trailer platform and is operable to at least one of remove heat from the electric drive motor or clear debris from the trailer.
