Advantage and features of ST180 water well drilling equipment
1, Easy and flexible full hydraulic control
The water drilling rig's speed, torque, thrust axial pressure, reverse axial pressure, thrust speed, and lifting speed can be adjusted at any time to meet the requirements of different drilling tool working conditions and different construction processes
2, Top-drive slewing propulsion lift
This bore well rig is easy to connect and disconnect the drill pipe, shorten the auxiliary time, and also facilitate drilling with the pipe.
3, Multifunctional drilling process
This drilling rig adopt air DTH drilling and mud pump circulation drilling process .it is optional items to install mud pumps, foam pumps and generators in to the drilling machine chassis
4, High efficiency
Due to the full hydraulic and top-drive slewing propulsion lifting, it is suitable for various drilling processes and various drilling tools, with convenient and flexible control, fast drilling speed and short auxiliary time, so the operation efficiency is high.
5, low cost
DTH drilling is mainly based on DTH drilling technology. DTH rock drilling has high efficiency and lower cost per meter.
7, Positive and negative axial pressure adjustment
The optimal impact efficiency of each impactor has its matching optimal shaft pressure and speed. During the drilling process, as the number of drill pipes increases, the axial pressure on the impactor also increases. Therefore, the positive and negative axial pressure valves are adjusted during construction to ensure that the impactor can obtain a more suitable axial pressure. At this time, the impact efficiency is higher.
8, hydraulic oil pump
parallel gearbox design (patent) oil pump unit separate, power supply is adequately allocated, hydraulic system unique design, maintenance and simple cost;
9,power head device
gearbox integrated casting, dual motor power, large torque, durable, low maintenance costs;
10, lifting force
patent design composite boom, small arm volume, long stroke, double cylinder lifting, increase tonnage;
11. Each rig is equipped with a stopper to raise the boom to protect the cylinder and ensure work safety;
12. Each hydraulic oil pipe is covered with a protective jacket to make the oil pipe have a longer service life.
