The power head of SD1000 core drill is designed by French technology. The structure is in the form of double motor and mechanical gear change. It has a large speed change range and large torque at the low-speed end, which can meet the requirements of different drilling methods.
The power head of SD1000 core drill has high transmission accuracy and stable operation, which can better reflect its advantages in deep hole drilling.
The feeding and lifting system of SD1000 core drilling rig adopts oil cylinder chain multiplication mechanism, which has long feeding distance and high operation efficiency.
SD1000 core drilling rig has fast lifting and feeding speed, saves a lot of auxiliary time and improves drilling efficiency.
The guide rail of the main tower of SD1000 core drilling rig adopts V-shaped structure, the connection between the power head and the main tower is rigid, and the high-speed rotation is stable. Full hydraulic core drill.
The power head of SD1000 core drill adopts the mode of automatic opening.
SD1000 core drill is equipped with gripper and shackle, which is convenient and fast to disassemble drill pipe and reduce labor intensity.
The hydraulic system of SD1000 core drilling rig is designed according to French technology. The rotary motor and main pump are plunger type, which is safe and reliable.
The mud pump of SD1000 core drilling rig is hydraulically controlled, and various operations of the drilling rig are centralized, which is convenient to deal with various downhole accidents.
