Specifications

positive displacement drill:
The down-hole drill motor is a kind of downhole drill tool driven by mud.

positive displacement drill

As mud fluid from the mud pump enters the motor via the by-pass valve, a certain pressure difference is formed at the inlet and outlet of the motor, pushing the rotor to rotate. Torque and rotate speed are transferred via the cardan shaft and the driving shaft to the bit.

Performance of the down-hole drill motor depends mainly on performance parameters of the screw motor.
