Reasons affecting the low torque transmission efficiency of horizontal directional drilling rigs

1. Wear of transmission parts: such as gears, chains, belts, etc., which are worn out after long-term use, resulting in poor meshing or slipping, causing energy loss.
2. Insufficient lubrication: The transmission system lacks sufficient lubrication, which increases the friction between the parts and affects the torque transmission.
3. Drill rod bending or deformation: The drill rod bends or deforms during use, resulting in additional resistance and energy loss during torque transmission.
4. Loose connection: The connection between the drill rod and the drill rod and the drilling rig is loose, the torque transmission is not tight, and energy leakage occurs.
5. Equipment aging: After long-term use, the overall performance of the drilling rig decreases, including the efficiency of the transmission system.
6. Complex geological conditions: Hard and uneven geology is encountered during drilling, which increases resistance and requires greater torque, but the transmission efficiency is affected.
7. Mud blockage: The mud channel is blocked, affecting the lubrication and cooling effects, and increasing the friction resistance.
8. Poor sealing: The transmission system is not well sealed, resulting in lubricating oil leakage or impurities entering, affecting the normal operation of the components.
9. Control system failure: If the electronic or hydraulic system that controls the torque output fails, the torque output may be unstable or inaccurate.
