DOWNHOLE TURBINE MOTOR AND RELATED ASSEMBLIES

摘要

A turbine drive may include a rotor that includes multiple turbine blades arranged in one or more turbine stages, as well as a stator cooperating with the rotor to direct fluid against the turbine blades and convert hydraulic, kinetic energy into rotational energy. The rotor may be fixed to the shaft to rotate synchronously therewith. The stator may be formed of multiple components that can be coupled together to define the stator and encompass the turbine blades of the turbine stages of the rotor. Two stator halves may each include vanes for positioning above and below a corresponding turbine stage, to direct fluid against the turbine blades. The stator may also be connected to a housing that encompasses the stator. Longitudinal slots and tabs on the stator and housing may hold the stator stationary relative to the housing.
