Abstract: An electrically operated displacement pump includes an electric motor having a stator and a rotor. The rotor is connected to the fluid displacement member to drive axial reciprocation of the fluid displacement member. A drive mechanism is disposed between and connected to each of the rotor and the fluid displacement member. The drive mechanism receives a rotational output from the rotor and provides a linear input to the fluid displacement member.

Abstract: 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.

Abstract: Rotating equipment includes driver equipment, driven equipment and a rotating shaft coupling. The driver equipment includes a driver support connected to a stationary driver shaft, and also includes a driver arranged on the driver support with a driving shaft to rotate and provide a rotational torque. The driven equipment includes a driven unit support connected to a stationary driven unit shaft, and also includes a driven unit arranged on the driven unit support with a driven shaft to respond to the rotational torque and rotate. The rotating shaft coupling couples the driving shaft to the driven shaft and applies the rotational torque from the driving shaft to the driven shaft. The stationary driver shaft couples to the stationary driven unit shaft to provide a static torque load to counteract the rotational torque applied from the driving shaft to the driven shaft during operation.
