Full rotary drilling rig

Descripción del producto

Full rotary drill is a kind of equipment for underground engineering construction, its construction principle is as follows:



1. Drill pipe conveying: The full rotary drill sends the drill bit into the ground through the drill pipe conveying system to complete the drilling operation. The drill pipe conveying system usually includes drill pipe, drill pipe connector, drill pipe chuck and other components.



2. Drilling operation: The full rotary drill achieves drilling operation by rotating the drill rod and drill bit. The drill is powered by a hydraulic system that rotates the drill bit and applies pressure to create holes in the ground.



3. Drilling and coring: The full rotary drill can sample underground rock formations through the coring device for geological exploration and analysis.



4. Drilling wash: The full rotary drilling rig will inject cement paste or mud into the drilling hole through the flushing system during drilling to remove debris in the hole and reduce the temperature of the drill bit.



5. Drilling pipe installation: In some cases, the full rotary drilling rig can also strengthen the drilling hole by installing drilling pipes to ensure the safety of engineering construction.



In general, the full rotary drilling machine through the rotating drill bit, drill pipe conveying and washing system and other working principles, to complete the drilling operations of underground projects.
