5LZ73x7.0 Downhole screw drill tools/mud motor for hdd drilling equipment
1.Product description
Specification of downhole motor
Downhole motor is a kind of downhole dynamic drilling tool upon 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.
2.Recommend parameter
1.Material: High manganese steel
2.Standard: API downhole motor
3.Features: Big torque, high effective, wide flow rate range, running stable and long using time.
4.Specifications: Fit for 3 1/2"--17 1/2" well hole, including straight body, single- bent and double-bent construction.
