Being an appointed device producing downhole motor for CNPC, we launched a comprehensive set of layout and producing technological innovation and unique tools from Smith Inc, United states of america, such as produciotn line for production and total device assembly, production line for heat treatment method managed ambiance, and creation line for stator rubber. In 2000, we have made technology enchancement, capability growth and equipment substitute. The existing production potential has attained the global innovative stage.
Now we can produce eighteen varieties of 2 three/eight”- eleven 1/four” ( Dia. sixty-286mm), three sorts of nozzle stress drop series of 3.5Mpa, 7Mpa and 14Mpa, solitary head and multi-heads, single bend ,double bends and adjustable angle ranging from degree -three diploma to match with the a lot more than four hundred varieties of downhole motors applied iwth vairous kinds of centrilalizers. The scope of nicely gap is two seven/8″-26″ (Dia seventy three-660.4mm), the output torque is 118-18010 N.M and the output pace is sixty-500 rpm.
Downhole Motor |
Downhole motor is a kind of downhole dynamic drilling instrument pushed by the electricity of drilling mud. Mud stream from the outlet of a mud pump flows through a by-go valve into the motor. This stream creates stress loss at equally inlet and outlet of the pump, to drive the rotor into rotating, and to transmit the torque and speed onto the little bit. The downhole motor residence mainly relies upon on its property parameters.
Motor Assembly |
Downhole motor rotor is made from large high quality alloy steel, whilst s-rotor is produced of rubber. Substantial drive and tearing energy of the rubber stator permits the device to run in the large temperatures (about one hundred eighty ºC ) and high oil mud condition. All these benefits assist to keep effective procedure.
We create the downhole motor with an external coating on the motor rotor that provides
the tool a considerably lengthier service existence.
Cardan Shaft Assembly |
The operate of cardan shaft is to change planetary motion into fastened consistent rotation of push shaft, to transmit torque and velocity from motor on the drive shaft and to the bit.
Push Shaft Assembly |
The driveshaft assembly converts the eccentric movement of the rotor into concentric rotation for the bearing assembly. It also accommodates any angle established on the adjustable bent housing (or fastened bend housing) and carries the thrust load from the rotor brought on by the strain fall throughout the electricity section.
The generate shaft assembly are solid using exceptional alloy metal, it presents the shaft assembly excellent power and toughness and also significantly enhance the anti-fatigue capacity for the duration of the rotating motion, as a result supplying the downhole motor a considerably more time provider existence.
Our Downhole motors arrive in dimensions ranging from Φ43mm to Φ286mm.
