High Performance Downhole Mud Motor for Directional Drilling with
Long Service Life
Tiptop is specialized in designing & manufacturing mud motor, motor
manufacturing, testing and maintenance equipment. The stable
quality and high performance of our mud motors, spare parts and
equipment have been effectively proven by customers in Russia,
India, Iran and China.
Downhole Mud Motors, also called Positive-Displacement Motors
(PDM), make use of a power generation section which is made up of a
rotor/stator combination. In order to move a rotor part, a PDM
requires hydraulic power from drilling fluid flowing through the
power generation part. With a PDM, the stator and rotor work in
tandem in the same way that gears do. The stator acts as the outer
gear, and is made from a moulded elastomer featuring at least two
lobes. The OD of the elastomer is protected by a secure metal
casing. The rotor is positioned within the stator, and acts as an
internal gear. This rotor is made of metal, and will have one less
gear or lobe than the stator. Because of this difference, a cavity
is created which is filled with drilling fluid when the PDM is
downhole. This cavity acts as a wedge when it is put under
pressure, and because the drilling fluid itself can’t be
compressed, the force applied to the top of the wedge causes the
rotor to move.
Tiptop downhole motor can work around 200 hours for one running in
general and working life of the power section has reached more than
1,000 hours. Our company is able to provide all sizes and
configurations of the downhole motor. We provide specific design
products according to the customer's requirements for the torque,
displacement, well temperature and other parameters.
•Size Range: Available from 1-11/16”OD to 11-1/4”OD
•Types: Adjustable bend housing type, Water based mud type (conventional
type), Oil-based mud type, Salty based mud type
•Structure: Consists of Bearing section assembly, Universal coupling assembly,
Power section assembly, Anti-drop device assembly and By-pass valve
assembly or Crossover sub.
•Advantages
•With the diversity and flexibility to work in all drilling
environments.
•Utilization of high quality materials, including forged steel
drive shafts (laser welding alloy on drive shaft surface), which
reduces wear and tear and down-time for servicing.
•With safety anti-drop device which reduces the probability of
residual motor parts left in the drill string in the event of
connection failure.
•High quality power section designs which efficiently maximize the
amount of speed and torque being transmitted to the drill bit.
•Tungsten carbide radial bearings which significantly reducing wear
and improves durability and consistency in performance.
Note: We have the capacity to design and customize spare parts
according to your requirements/drawings. Welcome to contact us to
customize your downhole motor and spare parts.
