Product Description

Product Application

Downhole motor is a kind of downhole dynamic drilling tool drove by the power of drilling mud. 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.

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 180ºC 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.

Cardan shaft assembly

The function of cardan shaft is to convert planetary motion into fixed constant rotation of drive shaft, to transmit torque and speed from motor on the drive shaft, and to the bit.

Drive shaft assembly

The drive shaft assembly is made of hard alloy radial bearing,a new type of cemented tungsten carbide give the bearing a better abrasive resistance. A unique sintering process with copper nickel alloy makes the connection area much stronger and abrasive resistance in the friction high temperature condition.The drive shaft assembly were forged with superior alloy steel ,it give the shaft assembly good strength and toughness and also greatly improve the antifatigue capacity during the rotating movement,so give the downhole motor a much longer service life. Our Downhole motor cover the size from Φ43mm to Φ286mm.
