Hydraulic Mobile Oil Drilling Rig DR-150 uses a variety of advanced control technologies, including electro-hydraulic proportional control, load-sensitive control, etc. Automatic pipe disassembly and assembly device improves work efficiency, reduces operator's labor intensity and manual error operation, and reduces construction personnel and construction costs. The upper and lower anchors are driven by hydraulic pressure. The anchor has a large force and is easy to operate. The two-speed spindle drive runs at low speed during drilling and dragging backwards to ensure smooth structure; and it can accelerate sliding at twice the speed, thereby reducing auxiliary time and improving the work efficiency when the drill returns and disassembles the drill pipe . No load. The engine has the characteristics of increasing turbine torque. When encountering complex geological conditions, the power can be immediately increased to ensure drilling power. The spindle drive speed is high, the drilling effect is good, and the construction efficiency is high. It is easy to control precisely when performing various functions (such as thrust / retraction and rotation), and is easy and comfortable to operate. The wire rope controller can be used by one person to complete the disassembly and assembly operation, which is safe and efficient. The patented floating vice can effectively extend the service life of the pipeline. Equipped with engine, hydraulic parameter monitoring alarm and multiple safety protection measures to effectively protect the safety of operators and machines.
