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.

Water pump with an impeller driven by an electrical machine comprising a housing cap and a volute with an input and an output and a boot hosting a stator and a rotor of the electrical machine and an electronic board mounted at the side apart from the impeller and covered by the cap housing, characterized in that the stator stack is over molded with a first plastic material and at least the stator stack, the wires and pins are over molded with a second plastic material to form a cylindrical ring boot and a heat sink that seals a cylindrical opening of the boot.

Embodiments of the invention provide a ring-style terminal block for supporting electrical connections. The ring-style terminal block includes an annular component having a radially inward facing surface at least partially defined by a first radius, a radially outward facing surface at least partially defined by a second radius larger than the first radius, a top surface extending between the radially inward facing surface and the radially outward facing surface, and a bottom surface. The bottom surface extends between the radially inward facing surface and the radially outward facing surface. The bottom surface is opposite the top surface and separated from the top surface by a thickness. The terminal block also includes a plurality of terminals spaced apart circumferentially and formed integrally within the annular component.

The present disclosure relates to a sampling pump configured for use in a wellbore for pumping liquid collecting in the wellbore. The sampling pump has a pump component including a motor and an outer housing configured to be inserted into the well bore. The outer housing has an inlet and an outlet. A fluid sensor detects when the inlet of the outer housing is positioned in the liquid in the wellbore. A flexible electrical cable assembly supplies power to the motor and the fluid sensor, and also communicates with the motor and the fluid sensor. A user control panel communicates with the flexible electrical cable and enables a user to control on and off operation of the DC motor from the control panel. The user control panel also has a component which is responsive to signals from the fluid sensor to indicate when the inlet is at least partially submerged in the liquid within the wellbore, as the pump is lowered into the wellbore.

A hanging bracket for supporting a suspended apparatus and a control unit housing includes a base having a first end and a second end. The first end includes a first surface and a first screw boss therethrough, and the second end includes a second surface and a second screw boss therethrough. The bracket also includes a support portion vertically spaced from the base, where the support portion adapted to support the suspended apparatus, and a neck extending between the base and the support portion. At least the first surface of the first end of the base, the second surface of the second end of the base, and the first and second screw bosses collectively form an interface configured for juxtaposition with complementary surfaces and screw holes of the control unit housing.
