Description
Downhole Stage Mud Motor 6 3/4" for Directional Well Drilling
Downhole Mud Moto is a kind of downhole dynamic drilling tool powered by mud, which is composed of four assemblies: by-pass valve,motor,cardan shaft and drive shaft and the rubber part.
The function of a universal joint is to convert the planetary motion of the motor into the fixed axis rotation of the transmission shaft, transmitting the torque and speed generated by the motor to the transmission shaft and drill bit. Universal joints are often of the flexible shaft type.
The function of the transmission shaft is to transmit the rotational power of the motor to the drill bit, while bearing the axial and radial loads generated by the drilling pressure
