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.
