Working Principle of Drilling Rig

The multifunctional drilling rig is a kind of rig that uses diesel engine as power to drive the hydraulic oil pump to produce pressure oil, which drives the hydraulic motor and hydraulic cylinder through the reversing valve to realize the rotation, propulsion, leveling and lifting and lowering of the drilling frame, and complete various predetermined actions; compressed air is provided by the air compressor, and grouting drilling can be carried out by the centrifugal pump to meet the needs of different formations.

Define Hydraulic Drilling Rig

A new, efficient, and multifunctional full hydraulic drilling rig, which is mainly used for drilling water wells, monitoring wells, geothermal air conditioning holes, hydropower cofferdam grouting holes, dam anti-seepage grouting holes, foundation reinforcement grouting holes, open-pit mining, anchoring, national defense projects, and other deep hole rock drilling work. Since the drilling rig is equipped with a high-power hydraulic motor, hydraulic drill arm, and high-pressure down-the-hole impactor, its rock drilling efficiency is higher than other types of drilling rigs.
