1. The slag discharge pipe on the power head is made of special steel and thickened to extend the service life by more than10 times. The diameter of the slag discharge pipe is increased to 89MM, which reduces the possibility of slag blockage.
2. Low failure rate, small model and large torque. The rotation speed can be adjusted according to different workingconditions 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 workcontinuously under outdoor high temperature climate conditions.
4. High-efficiency driling, equipped with a Weichai 129KW engine for strong power, rapid rock cuttingsremoval.
5. Reliable and efficient air pre-filter system, which effectively filters out dust in the intake air, is easy to clean and maintain,effectively reduces enaine wear, extends service life, improves work efficiency, and makes it suitable for harsh working conditions.

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
