ST 400 Pneumatic Borewell Machine Advantage
1.Easy and flexible full hydraulic control
The 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
It is easy to connect and disconnect the drill pipe, shorten the auxiliary time, and also facilitate drilling with the pipe.
3.Multifunctional drilling
Various drilling processes can be used on this rig, such as: down-the-hole drilling, through-air reverse circulation drilling, gas lift reverse circulation drilling, cutting drilling, roller drilling, tube drilling, and Core drilling under development and more.The drilling rig can be equipped with mud pumps, foam pumps and generators according to user needs. The rig is also equipped with various hoists as standard.
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.
6.High outrigger and Tracked walking
The high outriggers are convenient for loading and transportation, and can be loaded directly without crane. Tracked walking is more suitable for muddy field movement.
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.Rig chassis
It can be a tracked self-propelled chassis or a vehicle-mounted self-propelled chassis. 9.High configuration
The main components and hydraulic system are all famous brands. In addition, the main frame of the rig is made of high-quality high-strength low-carbon alloy steel, which increases the overall strength and is very resistant to wear.
10.Diesel engine
This drilling water machine adopt 65KW Quanchai engine
11.Lifting force
design composite tower, 3.4m long stroke, double cylinder lift capacity 15 ton .
