Oil Drilling Tools (5LZ73)

Dowehole motor is a kind of downhole dyc drilling tool upon the power of drilling mud. It can enhance the drilling speed highly and increase economic benefit largely.

Dowhole motor is made up of 4 parts which are driving assembly, motor assembly, connecting assembly, dump assembly. The mud stream from the outlet of mud pump flows into the motor by transit the pump valve. This stream produces pressure loss between the inlet of motor to the outlet of motor that can push the rotor of motor into rotating, and to transmit the torque an rotate speed onto the bit used by connecting assembly and driving assembly. In fact the downhole motor is a kind of energy transformation machine which transform the pressure of liquid to the energy of engine.
