Abstract:

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.

Abstract:

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.

David Devon Todd - Chicago IL, US

International Classification:

A47C 7/62
A47C 1/10

Abstract:

A disposable barber-chair headrest protective covering is provided to be used specifically for the headrest of a barber-chair. The disposable barber-chair headrest protective covering will be used to cover the headrest of the barber-chair before each service to prevent the cross-contamination of germs, hair debris, and infectious disease that can be transmitted from the head, scalp, or/and hair. The disposable barber-chair headrest protective covering will also minimize erosion and damage to the barber-chair caused by chemical build-up.The disposable barber-chair headrest protective covering will be made of material that is disposable, inexpensive, and flexible, with an elastic (or similar) band adhesive or sown in at the edges for flexibility. The elasticity allows the covering to hug the headrest of the barber-chair and be close-fitting. It can be applied by opening the elastic edges of the invention and sliding it onto the barber-chair headrest.

Abstract:

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.

Abstract:

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. The single VFD converts the electric power of at least 13.8 kV to a VFD rated voltage level of at least 4160 V and drives the single shaft electric motor at the VFD voltage level of up to 4160 V to control the operation of the single shaft electric motor and the single hydraulic pump. The single shaft electric motor drives the single hydraulic pump with the rotation at the rated RPM level of at least 750 RPM. The single hydraulic pump continuously pumps the fracking media into the well at the HP level of at least 5000 HP. The single hydraulic pump operates on a continuous duty cycle to continuously pump the fracking media at the HP level of at least 5000 HP.
