The underwater hole impactor is an important part of drilling equipment, and its performance directly affects the quality and efficiency of drilling. In the classification of submerged hole impactor, according to the difference of working wind pressure, it is mainly divided into high wind pressure submerged hole impactor and low wind pressure submerged hole impactor. Although the two are similar in basic working principle, there are obvious differences in performance characteristics, application fields and technical specifications.
Brief description of working principle
Whether it is high wind pressure or low wind pressure submerged hole impactor, its working principle is based on the principle of impact crushing. The piston is driven by compressed air, which creates an impact force and causes the drill to break the rock. As a power source, wind pressure is the key to drive the impactor.
Comparison of performance characteristics
High wind pressure hole impactor:
High impact: Due to the high working wind pressure, it can provide greater impact force, suitable for drilling in hard rock formations.
High efficiency: The high impact force means that the rock is broken up faster, resulting in increased drilling efficiency.
High energy consumption: High wind pressure means greater energy consumption, which has higher requirements for the stability and heat dissipation performance of the equipment.
Low wind pressure hole impactor:
Low impact force: the working wind pressure is low, the impact force is relatively small, suitable for soft or medium hardness rock formations.
Low energy consumption: Because the wind pressure is low, the energy consumption is relatively small, and the heat dissipation requirements of the device are relatively low.
Wide application: Due to the moderate impact force, the low wind pressure submerged hole impactor can show good drilling effect under various geological conditions.
Application field differences
High wind pressure submerged hole impactor is widely used in mining, large-scale infrastructure projects and other occasions that need to go deep into hard rock formations. The low wind pressure submerged hole impactor is more widely used in soil exploration, well drilling, small construction projects and other fields.
Specification variance
High wind pressure submerged hole impactors usually need to be equipped with more powerful compressors to provide adequate working wind pressure. Its structural design also places greater emphasis on impact and wear resistance. The low wind pressure submerged hole impactor is relatively light, and the requirements for the compressor are relatively low.
In summary, there are obvious differences in performance characteristics, application fields and technical specifications between high and low air pressure submerged hole impactors. In practical application, it is necessary to select the appropriate type of submerged hole impactor according to the specific geological conditions and engineering requirements.
