Do You Know How To Select A High-quality Horizontal Directional Drilling Rig?

With the horizontal directional drilling rig has been widely used in China, this machine does not need to open the ground when in use, which can not only protect the environment to a great extent, but also will not affect people's travel. Therefore, during construction, more and more people will rent this kind of machine to work. Do you know how to choose a high-quality horizontal directional drilling rig? The following editor has sorted out some information to share with you, hoping to help you.

1. The torque of the drilling rig is selected according to the needs of the project, and the horizontal directional drilling rig can work reliably in the high area of the drilling rig. The high area of the drilling rig usually refers to that the average progress of the drilling rig is more than 5m/h during normal drilling.

2. The drill pipe needs to transmit all the torque of the power head to the drill bit at the bottom of the hole, and stably transmit the pressure of the pressurized hydraulic cylinder, the dead weight of the power head and the dead weight of the drill pipe to the drill bit tens of meters below. Therefore, when drilling into a relatively hard formation, the drill pipe not only needs to bear a large torque and a large WOB, but also needs to overcome a large bending moment. If the drill pipe fails to meet this requirement, it is easy to be damaged.

3. At present, the adjustment structure of drilling rig mast is divided into triangle and parallelogram, which have their own advantages. The adjustment structure of the parallelogram drilling mast will be more practical from the perspective of the on-site installation and disassembly of the drilling rig and the crossing of air obstacles.

4. The external rotary drilling rig should have an automatic sounding device, which can measure both each drilling depth and the total drilling depth. This is essential for the drilling quality and operation of horizontal directional drilling rig.
