Framework
Mainly consists of a power system, drill pipe, drill bit, core tube, feed system, etc.

Provides the power and torque required for drilling.

Connects the drill rig to the drill bit and transmits rotational forces.

The outer tube connects the drill bit and transmits torque; the inner tube stores the core.

Cuts or grinds the rock, mainly to form a circular hole and to retain the core.

Holds the core at the root of the core during lifting and prevents the core from falling out.

Circulates the drilling fluid, cools the drill bit and equalizes the formation pressure.

Controls the pressure of the drill bit on the formation and the drilling speed.

monitors and regulates parameters such as drilling pressure, rotational speed, flushing fluid flow rate, etc.
Ordering Process
When selecting a hydraulic core drilling rig, it is necessary to choose based on specific working conditions, such as geological conditions, drilling diameter and depth requirements, terrain conditions, etc.
Once the specific operating conditions of the hydraulic core drilling rig have been determined, the appropriate core drilling rig model can be selected, such as drill bit size, drill rod thickness, and matching power.
When placing an order for a hydraulic core drilling rig, it is necessary to double-check the drilling parameters, technical agreement, and configuration requirements.
