Crawler Type Pneumatic Water Well Drilling Rig 400 Meter Water Well Drilling Machine For Sale

ST 400 Pneumatic Borewell Machine Product Information

Full hydraulic drilling rig mainly used to drilling wells,irrigation wells,ground source heating pump wells and boreholes for other purposes,especially for mountain and rock formation well projects.The rig can be drill in different layers.deep water well drilling rig uses full hydraulic control, and the top drive to drive the rotation of drilling tools with very high drilling efficiency.reasonable overall layout uses the tractor-mounted or full ground challis for transportation with good maneuverability.Very flexible in difficult roads and can be widely used in many fields such as resource exploration of hydrology wells, coal bed methane, the shallow layer of shale gas, terrestrial heat, etc, and can also be used for coal-mine gas exploitation salvage work.The top mounted driving head principal shaft has a great drift diameter, suitable for many kinds of construction work such as slurry drilling, air drilling, and air foam drilling, meeting the demands for well-drilling at different terrain strata..

ST 400 Pneumatic Borewell Machine Features

1. It improves drilling efficiency and reduces labor intensity With hydraulic automatic feeding mechanism.

2. It can be achievedwithout stopping to change rods, easy to operate, safe and reliable with ball clip holding mechanism orhydraulic chuck.

3. It hashole bottom pressure gauge to be easy to master the situation in the hole.

4. It also has advantage of Compact structure,concentrated handle, small footprint, light weight, strong decomposition, easy tomove. It can be operated in plains and mountainareas.

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 .
