An electric driven hydraulic fracking system is disclosed. A pump configuration that includes the single VFD, the single shaft electric motor, and the single hydraulic pump that is mounted on the single pump trailer. A power distribution trailer distributes the electric power generated by the power generation system at the power generation voltage level to the single VFD and converts the electric power at a power generation voltage level to a VFD voltage level and controls the operation of the single shaft electric motor and the single hydraulic pump. The power distribution trailer converts the electric power generated by the power generation system at the power generation level to an auxiliary voltage level that is less than the power generation voltage level. The power distribution trailer distributes the electric power at the auxiliary voltage level to the single VFD that controls an operation of the of the auxiliary systems.

An electric driven hydraulic fracking system is disclosed. A pump configuration includes the single VFD, the single shaft electric motor, and the single hydraulic pump mounted on the single pump trailer. A controller associated with the single VFD and is mounted on the single pump trailer. The controller monitors operation parameters associated with an operation of the electric driven hydraulic fracking system as each component of the electric driven hydraulic fracking system operates to determine whether the operation parameters deviate beyond a corresponding operation parameter threshold. Each of the operation parameters provides an indicator as to an operation status of a corresponding component of the electric driven hydraulic fracking system. The controller initiates corrected actions when each operation parameter deviates beyond the corresponding operation threshold. Initiating the corrected actions when each operation parameter deviates beyond the corresponding operation threshold maintains the operation of the electric driven hydraulic fracking system.

Disclosed is an electric pump, comprising a stator assembly, an electric control board assembly, and a conduction member capable of conducting electricity, wherein the stator assembly is electrically connected to the electric control board assembly; the stator assembly comprises a stator core; and the conduction member is electrically connected to a reference ground layer of the electric control board assembly and to the stator core, such that the influence of accumulated charges on the electric control board assembly is reduced, thereby improving the performance of the electric pump.

A low profile electric pump arrangement having a motor housing connected to a pump element of a transmission for a vehicle. An inverter housing connected to the motor housing and has a where an electronics control unit (ECU) connects through the inverter housing to selectively supply power to the motor within the motor housing. The recess and the ECU are covered and sealed off from the elements by a plastic cover. In order to obtain a low profile of the electric pump arrangement so it can fit within a desired packaging line on a transmission casing a metal bracket is over molded into the plastic cover. The metal bracket has at least one exposed surface that engages the inverter housing to hold the plastic cover onto the inverter housing in a position so that the plastic cover covers and seals the ECU and recess at the second side of the inverter housing.

An electric driven hydraulic fracking system is disclosed. A pump configuration that includes the single VFD, the single shaft electric motor, and the single hydraulic pump that is mounted on the single pump trailer. A pump configuration includes a single VFD configuration, the single shaft electric motor, and the single shaft hydraulic pump mounted on the single pump trailer. The single VFD configuration converts the electric power at the power generation voltage level distributed from the power distribution trailer to a VFD voltage level and drives the single shaft electric motor to control the operation of the single shaft electric motor and the single hydraulic pump. The VFD voltage level is a voltage level that is required to drive the single shaft electric motor. The VFD configuration also controls operation of the auxiliary systems based on the electric power at the auxiliary voltage level.

A multiple-pump device for a vehicle may include a housing. The housing may include at least a first drive device for driving a first drive shaft with a first impeller, and a second drive device for driving a second drive shaft with a second impeller. The multiple-pump device may include a bearing shield penetrated by the first drive shaft and the second drive shaft. The beating shield may separate a wet region with the first impeller and the second impeller from a dry region with the first drive device and the second drive device. The multiple-pump device may include power electronics arranged in the dry region and connected with the bearing shield to transfer heat.

A pump, in particular for a fluid circuit in a vehicle, for example a coolant pump with a multi-part housing that has a pump chamber, wherein an impeller is arranged in the pump chamber, wherein the pump chamber is bounded by a pump housing and a further housing part of the multi-part housing, wherein the pump housing and the further housing part each have a flange surface that rest against one another, and wherein one of the two flange surfaces has at least one annular groove and the other of the two flange surfaces has at least one circumferential web which engages in the annular groove.

Certain embodiments of the present application relate to a variable frequency drive (VFD) cabin for a pump configuration including a mobile trailer on which the VFD cabin is to be mounted. The VFD cabin generally includes a medium-voltage VFD and a ventilation system. In certain embodiments, the ventilation system is configured to generate an overpressure condition within the cabin to discourage the entry of dust and debris into the cabin. In certain embodiments, one or more components of the medium-voltage VFD are coupled to the floor of the cabin via a vibration damping system. In certain embodiments, the VFD cabin may be directly coupled to a chassis of the mobile trailer without an intervening suspension being provided between the VFD cabin and the chassis.

A variable speed pumping system including a variable speed pump, a remote user device, and an auxiliary device is provided. The variable speed pump includes a motor, a drive, a housing including a drive cover, and an onboard controller. The onboard controller includes a plurality of buttons formed in the drive cover, a touchscreen interface positioned on the drive cover, a main circuit board including a non-transitory computer readable medium, the main circuit board being electrically coupled to the touchscreen interface, the motor, and the drive, a wireless communication unit electrically coupled to the main circuit board, and a selectively removable IO expansion module. The onboard controller is configured to control one of a flow rate of the pump or a speed of the motor for a period time and actuate the auxiliary device based on input received on one of the onboard controller or the remote user device.
