HDD(Horizontal Directional Drilling) Projects
HDD(Horizontal Directional Drilling) Projects is a construction technology for laying various underground public facilities (pipelines, cables, etc.) without excavating the surface of the ground. HDD(Horizontal Directional Drilling) is widely used in the construction of pipelines for water supply, electricity, telecommunications, natural gas, oil, etc. Horizontal directional drilling technology is a construction technology that combines the directional drilling technology of the petroleum industry with traditional pipeline construction methods. It can improve the construction speed, high construction accuracy, and lower cost, and is widely used in pipeline laying construction projects. HDD(Horizontal Directional Drilling) construction will not hinder traffic, damage green spaces and vegetation, and will not affect the normal life and work order of shops, hospitals, schools, and residents. It solves the interference of traditional excavation construction on residents’ lives, as well as the damage and adverse effects on traffic, environment, and surrounding building foundations.
Mud Motor for HDD(Horizontal Directional Drilling) Projects
ZH produces a variety of Mud Motor for HDD(Horizontal Directional Drilling), size from 43mm to 286mm, for used in the most complex drilling projects, our Mud Motor for HDD(Horizontal Directional Drilling) have the advantages of versatility and ease of use, reliable design, and suitable for any type of drill bit.
In order to obtain higher performance, ZH Mud Motor for HDD (Horizontal Directional Drilling) can also provide stators with rubber inside liners with iform thickness. The ZH Mud Motor for HDD (Horizontal Directional Drilling) is designed with streamline spindle section, radial support and high reliability Tungsten Carbide Radial Bearings or Axial Bearing, allowing the axial load of the drill bit to increase. In addition, the ZH Mud Motor for HDD (Horizontal Directional Drilling) can also be equipped with a bit stabilizer and an angle adjuster, from 0 to 3 °, or with a fixed tilt angle.
Earth drilling tools in previous HDD projects can’t meet the requirements of pipe line construction as the rock appears more and more frequently. A rock drilling tool is eagerly needed. ZH Mud Motor which is used in oil and gas well directional drilling is introduced into HDD projects and plays a more and more important role in nowadays HDD rock drilling projects.
Structure ZH Mud Motor for HDD (Horizontal Directional Drilling) Projects
The Mud Motor for HDD(Horizontal Directional Drilling) is composed of four major assemblies, a Bypass Valve, a Motor, a Universal Coupling Assembly and a Drive Shaft.
Working Principle of ZH Mud Motor for HDD (Horizontal Directional Drilling) Projects
Mud Motor is a part of the PDM drill, which is a volumetric downhole power drilling tool which uses drilling fluid as power to convert liquid pressure energy into mechanical energy. When the drilling mud pumped out by the mud pump flows through the bypass valve and enters the Mud Motor for HDD, a certain pressure difference is formed at the inlet and outlet of the Mud Motor for HDD, which drives the rotor to rotate around the axis of the stator, and transmits the speed and torque to the drill bit through the universal joint and transmission shaft, thus achieving drilling operations.
Features & Benefits of of ZH Mud Motor for HDD(Horizontal Directional Drilling) Projects
- ZH Mud Motor for HDD (Horizontal Directional Drilling) has available in fixed and adjustable housings.
- ZH Mud Motor for HDD (Horizontal Directional Drilling) performance parameters are closer to the theoretical design.
- ZH Mud Motor for HDD (Horizontal Directional Drilling) uniform temperature affects decreased due to the rubber deformation, reduced motor correction difficulty.
- During work the rubber becomes more resistant to deformation, rigidity increases, single stage pressure heightens, stiffness increases, wear slows down, becomes more efficient, and prolongs motor service life.
- Sensitive to temperature decreases, slow rubber thermal aging.
- ZH Mud Motor for HDD (Horizontal Directional Drilling) can ensures reliability and stability of downhole motor. After the single stage confined height, output efficiency increases.
- ZH Mud Motor for HDD (Horizontal Directional Drilling) has high work efficiency, the failure rate is low, and the construction progress is greatly improved.
