KYRC350 Reverse Circulation Drilling Rig

Product Introduction

KYRC350 reverse circulation drilling rig is a new, efficient, environmentally friendly and multifunctional crawler drilling rig. It uses double-wall drill pipe. After the inner tube is discharged, the discharged slag is collected by a cyclone collector. It can be used for sampling and analysis in geological exploration departments.
KYRC350 reverse circulation drilling rig can use compressed air reverse circulation down-the-hole drilling in various strata. The drilling rig’s drilling rig lifting, drilling rig compensation, drilling rod loading and unloading, rotation and feeding, outriggers, winches, walking and other actions are all realized by the hydraulic system, which greatly reduces the labor intensity and improves the construction efficiency and engineering quality.

Working Principle

The reverse circulation drilling rig adopts a double-layer drill pipe structure, and drills by sending air through the outer pipe and returning samples through the inner pipe;

High-pressure air is sent to the bottom of the hole from between the drill pipe and the hole wall;

Drill cuttings and rock powder are carried into the inner pipe under the action of air pressure difference;

Then enter the sample collection system through the cyclone separator.

This method is called reverse circulation, which is opposite to conventional positive circulation drilling.

Main Features

1. Air compressor is used to supply air and discharge slag. Various impactors and drill bits can be matched according to the size of the operating hole.

2. Low failure rate, small model and large torque. The rotation speed can be adjusted according to different working conditions to effectively improve the impactor footage efficiency.

3. The hydraulic system is equipped with an independent hydraulic oil radiator to ensure that the drilling rig can work continuously under high temperature outdoor climate conditions.

4. The movable slide can be pressed against the ground working surface through the compensating oil cylinder when the drilling rig is operating, which improves the rigidity of the drilling rig and ensures the working stability of the drilling rig.

5. The reliable and efficient air pre-filtration system can effectively filter out dust in the intake air, is easy to clean and maintain, effectively reduces engine wear, prolongs service life, and improves work efficiency, making it suitable for harsh working environments.
