Product Description

73mm PDM Downhole Drilling Mud Motor for HDD

1.Product description
Specification of mud 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.ADVANTAGES OF DOWNHOLE MOTOR
Increased rate of penetration.
Better hole deviation control.
Reduction in drill string failure rate.
Reduction in wear and tear of the swivel, Kelly, and rotary drives.
Reduction in fuel cost, since compared to rotary drilling, less energy is required to power a downhole motor.

4.Application of downhole mud motor 
A Variety of Types & the Capabilities In accordance with the actual drilling needs,we push out high,
midiem and low speed  downhole motors,of a variety of types with different functional configuration and application for all working conditions.
1.Standard type Standard motor,mud lubricating transmission shaft, straight, single and double bent.
2.Long type The torque is increased by 30%to 60%than standard ones, mud lubricating transmission shaft, straight, single and double bent.
3.High flow rate type The adoption of hollow rotor and different sizes of hard alloy jet nozzle to increase the incoming flow and bit power.
