    8 '' Directional Drilling Downhole Mud Motor For HDD Service 7 / 8 Lobes 4.0 Stages

    8'' Directional Drilling Downhole Mud Motor for HDD Service, 7/8 lobes, 4.0 stages

    Downhole mud motor is a kind of downhole dynamic drilling tool drove by the hydraulic power of drilling mud. Downhole motor consists of five assemblies, such as by-pass valve, Anti-drop assembly, motor, universal coupling and drive shaft. Mud stream from the outlet of mud pump flows through a by-pass valve into the motor. This stream produces pressure loss at both inlet and outlet of the pump, to push the rotor into rotating, and to transmit the torque and speed onto the bit. The downhole motor property mainly depends upon its property parameters.

    Tiptop downhole mud motor adopts near bit structure, adjustable universal coupling housing, stabilizers with different sizes, types and structures, and also universal coupling specially designed for large drill bit & large torque with larger torque bearing capacity, better impact resistance performance and running stability, and integral or interchangeable stabilizers with different sizes are available.

    The Major Parts:

    Power Section Assy. (Stator and Rotor): with stable performance during long term operation.

    Drive Shaft Assy.: Utilizing high quality materials including forged steel drive shafts, and Tungsten carbide radial bearings which significantly reduces wear and improves durability and consistency in performance.
