Abstract
An electrical submersible pump system for preventing high-pressure drawdown while starting includes a fixed-speed drive, hermetically-sealed motor including a motor shaft extending therefrom, a discharge pump including a pump shaft extending therefrom, and a torque converter interposing the motor and the pump. The torque converter includes a hollow body filled with a conversion fluid, a motor-side rotor mated to an end of the motor shaft and operable generate a vortex of the conversion fluid within the hollow body when the motor shaft is provided with a torque, and a pump-side rotor mated to an end of the pump shaft and rotatable as the vortex impinges on the pump-side rotor, and thereby providing a torque to the pump shaft to operate the discharge pump.
