Coiled Tubing Tools Mud Motor Hole Size 8 1/8"-9 5/8"
Product Descrption
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.
Motor Assembly
Downhole motor stator is machined from high quality alloy steel,
while rotor is made of rubber. It keeps the tool suitable for high
temperature and high oil mud system. Big force and tearing strength
of the rubber stator keeps the tool can also run under the high
temperature at about 180℃ and also the high oil mud condition. All
these benefits help to obtain the good operation effect. We have a
external coating on the downhole motor rotor, it gives the tool a
much longer service life.
