Application
A Reverse Circulation Drilling Rig Is A Professional Drilling Equipment That Operates On The Reverse Circulation Principle. It Rapidly Discharges Rock Cuttings And Mud From The Hole Through Negative Pressure Inside The Drill Pipe, Realizing Efficient Slag Removal And Continuous Drilling. It Can Be Adapted To Various Complex Formations Such As Sand Layers And Pebble Layers, And Is Mainly Used In Scenarios Like Bridge Pile Foundations, Water Well Construction, And Water Conservancy Projects. It Not Only Improves Drilling Efficiency But Also Reduces The Risk Of Hole Wall Collapse, Ensuring The Quality Of Hole Formation

Product Features:
1. Adopting the well-known brand HOWO 4x6 chassis, 2 front and 8 rear.
2. Equipped with Weichai 129KW engine, it has strong power and can remove rock chips quickly.
3. The hydraulic system is equipped with an independent hydraulic oil radiator to ensure that the driing rig can workcontinuously under high temperature outdoor climate conditions
.4. The movable slide can slide with the compensating cylinder to press against the ground working surface during drillingoperation, which improves the rigidity of the driling rig and ensures the working stability of the driling rig.
5. The reliable and efficient air pre-filter 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 workingenvironments.
