Efficient And Comprehensive Drilling Technology Alternative Air Dth Hammer
describe
Water wells use pumps that are used to drive water from the ground to your home. These pumps determine the lifespan of your well. Submersible pumps that are commonly used in many wells usually last from eight years to ten years. With proper maintenance and care, the lifespan can be increased to fifteen years.
Technical Parameters:
| Comparison of liquid-driven hammer drilling process and air DTH hammer drilling process | |||||||
| DTH-HAMMER | COMMAND liquid-driven hammer | ||||||
| Applicable strata | |||||||
| Complete bedrock formation, or hard rock | Like the DTH-hammer, the crushing efficiency is extremely high for hard formations. | ||||||
| Unsuited Stratum | The mud acts as a medium for the impactor, essentially mud drilling. Mud drilling is suitable for a variety of formations. And the wall protection ability is strong, it is not easy to collapse, and the fractured formation can also be processed by filling. | ||||||
| Sandy soil layers, fractured strata and other loose formations, when loose formations will blow up the walls of the holes, or blow into small "big bells", if the air compressor model is not well matched, it will cause drill cuttings at the bottom of the hole. Suspended in the wellhead, can not blow out, resulting in buried bottom and other hole bottom accidents. | |||||||
| Matching equipment | |||||||
| Drilling rig | Drilling rig | ||||||
| Generally hydraulic power head drill | The rig can be in various forms, and the COMMAND uses a truss structure, which is a high-strength square tube welding, has a high load and good torsion resistance, and is suitable for various aperture construction. The drilling diameter is 505MM. | ||||||
| The rig is a combined I-beam or channel steel structure that is lightweight but does not have torsion resistance. Therefore, it is only applicable to the air DTH hammer drilling process which does not require a large torque, and the general aperture can only reach within 200MM. | |||||||
| Air compressor | Mud pump | ||||||
| Selection basis: | Selection basis: | ||||||
| Air flow: annular gap between drill pipe and hole wall (aperture) | Flow: Ring gap between drill pipe and hole wall (aperture) | ||||||
| Wind pressure: depth | Pressure: Depth | ||||||
| Commonly used air compressors can only reach a depth of about 280 meters, the deeper the cost is, the higher the cost is. | Mud pump is the basic component of drilling rig. Because of the ever-changing strata, mud drilling must be used to solve complex strata. | ||||||
| The selection of mud pump only needs to be based on the depth and aperture of normal mud drilling. | |||||||
