127mm PDM Downhole Mud Motor For HDD
The Positive Displacement motor downhole motor is a kind of downhole power drilling tool powered by drilling fluid, also known as Positive Displacement motor (PDM). Its working principle is as follows: when the mud pump pumped mud flow through the bypass valve into the motor, a certain pressure difference is formed at the inlet and outlet of the motor, which pushes the rotor to rotate around the axis of the stator, and transmits the rotational speed and torque to the drilling bit through the cardan shaft and the transmission shaft to realize the drilling operation.
