ARC Series Air Reverse Circulation Drilling Rig

1.Brief Introduction:

  

ARC series air reverse circulation drilling rig is a new, efficient and environmentally friendly geological drilling equipment. It uses the latest air reverse circulation drilling technology from Master Research Institute, compressed air is used as the circulating medium to quickly discharge, the cuttings from the bottom of the hole through reverse circulation. Rock cuttings and dust are effectively collected and sorted through dust collectors, avoid sample contamination, ensure the accuracy of sample data. the drilling rig is mainly used in mineral exploration, hydrogeological exploration, engineering geological exploration and other fields, suitable for various geographical environments, including complex environments such as thin air at high altitudes, thick permafrost, and abundant groundwater. It is the preferred equipment for geological exploration drilling and other deep hole operations.

 

2.Techincal parameters:

 2.1 Efficient drilling: the air reverse circulation drill uses a closed circulation system to quickly discharge cuttings, reduce repeated crushing, and significantly increase drilling speed.

2.2 High sample quality: the rock chip dust samples obtained through air reverse circulation drilling are free from contamination, easy to classify and track, and can accurately locate the mineralization location.

2.3 Green and environmentally friendly: Using compressed air as the circulating medium, compared with traditional mud drilling rigs, it does not require a large amount of water and chemicals during the construction process, reducing pollution to the environment.

2.4 Full hydraulic operation: drilling rig lifting, power head rotation and feeding, drill rod connection and unloading and other actions are all realized by the hydraulic system, which greatly reduces labor intensity and improves construction efficiency.

2.5 Low maintenance cost: the air reverse circulation drilling rig has a simple structure, and key components are made of high-strength materials with strong wear resistance and corrosion resistance, which reduces the replacement frequency of wearing parts and has low maintenance costs.

2.6 Reliable power: adopt big brand diesel engine, strong power, stable performance and perfect after-sales service.
