1.Downhole drilling machine: When drilling a downhole gun hole with a aperture less than 150 mm, in addition to the application of a rock drill, it can also be used to drill a small diameter of 80 ~ 150 mm. When drilling a gun hole with a diameter of less than 70 mm in coal or softer mineral rock, it is generally used to drill or air drill, driven by a motor (or air motor) to drill the drill pipe, and the rock (coal) chips drilled out are discharged through the spiral groove on the drill pipe.
The Future of Portable Rotary Air Compressors
When the wind force is greater than level 6 during operation, the pile driver should stop the operation, and the oil cylinder should be used as an auxiliary support. If necessary, a wind rope should be added for fixing.When the crawler is piled, avoid the collision between the drill pipe reinforcement cage and other columns.
- Discharge Size The size of the discharge pipe affects how quickly mud can be expelled. Larger discharge openings can accommodate thick mud without clogging.
